One of the main issues all zoning systems have to overcome is trying to vary the airflow volume, when most residential HVAC equipment is constant volume. A true variable volume system has equipment designed to run on a wide range of airflow. There is high end residential equipment that is variable volume, with modulating heating and cooling. These high end systems, with variable capacity work well with zoning systems.
Their controller has to be in charge so all your really need from your thermometer is the off/on and heat/cool and fan on/off functions. The controller is tracking the duct pressure, room temp/humidity to adjust time on/off. Most smart thermometers don't really do much for room to room conditions but they make better guesses based on outside data and preferences.
That's a good opinion, but I gave up on Nest. I bought a Nest thermostat when it first came out because they promised they would make it compatible with Apple HomeKit, but they have broken that promise. I'm still waiting. Any company that breaks their promises loses my business.

Wooooooooooow. Love finding people who make progress on things and you find it's been relatively around for awhile because I was still stuck on duct dampers and mini splits as the only way to Zone a home
Really neat idea. The registers are a little ugly. Would like to see something that could take the existing registers, and mount under/OR replace the damper. Otherwise really neat.
Dipul, you would get a lot more respect if you actually had a tiny bit of HVAC experience. Your equipment is not for every house or project. Some homes just need an experienced HVAC tech to summarize their issues and come up with a solution. You are trying to be the next "Nest". I do admire your " Get rich or die tryin" mentality but have a little more respect for HVAC professionals. Some homes, they have the wrong size ducts, clogged air filters, small return duct, etc. and now you want people to believe your product is going to be the magic bullet. You want to get rich off something you don't really know anything about in the real HVAC world.
@@gretzkysyotes How do you install ductwork backward? You should get your facts straight before you throw all A/C contractors under the bus. By the way,jdere31760 is correct and these controls, They don't work too well. he made some statements that are just not correct. So ruin your system. You should fix it yourself too to keep those crappy contractors out of your house.
In the Netherlands we almost all have modulating, low temperature, central gas water heating, with water temperature from 30 to 60c (86-140F) when it is not freezing outside. All rooms have thermostats on the radiators and a central controller in the living room. All radiators are sized per room. The gas furnace is almost always extremely oversized for heating because is also supplies hot tap water.
You should make the outlet sensors so they screw on the the wall plate at the center screw. It will stop it from coming off when devices are unplugged.
it sounds like the engineer forgot one thing, most people are saying they need a bypass and that is correct for a non variable Hvac. In order to do it without the bypass you need a designed hvac for variable speeds to not over-pressure the flow. You need a max capacity btu but a variable fan speed. There will still be disadvantages, cost is one of them. size of the evaporator is another. A bypass could also be a good thing if they integrate a water heater into the loop instead of being a separate unit. I don't think current systems will not manage unless major deterioration happens. Plus modifying a hvac system vs designing one from the ground up will be better.
100% agreed but what makes me weird out is that as an IT/Technology professional myself, I would never recommend wireless connectivity as it is not as reliable as connected and if these registers are constantly opening and closing, they will eat through their batteries quickly.
Hi Im in the UK where ventilation and AC is beginning to happen, this is 6 years ago!! did this company ever make it ? is there something similar ? any links or info would be much appreciated. Regards
Installing dampers in the ducts means cutting into the sheet metal and is the domain of skilled tradesman charging high $/hr. Removing two screws and replacing the register as we see in the video is comparatively much easier.
One part of this system I'm not grasping. Suppose the original tstat for the system is in the living room. You now set the wireless system to sleep mode and it dampers off the living room. During heating season, the room inherently would get cold, tstat tells furnace to fire but you have now dampered off the register in the living room which will cause that room to heat either slowly or not at all. This then causes an inaccurate reading at the stat that doesn't represent the temperature spread in the entire house. So, you solve one problem with your cold bedroom but created another by having the furnace run longer. A poorly insulated home or inadequate system is very hard to overcome. You're not going to push much more cfm through ductwork that is designed incorrectly. Seems like a neat idea but doesn't solve all the issues. Should be a way for the hub to communicate with the heating and cooling system as well.
What doesn't make sense is before you can "damper" the air to the registers, you have to still fill the pipe, you lose pressure and velocity. Correctly done, the dampers would be at the trunk line and not at the end of the run. There is NO easy fix for a poorly designed ducting system period. These "how to" shows make everyone that has heat/cool issues and a credit card poor suckers. Best advice: if your homes heating and air is not doing the job.... Don't watch you tube videos... Call a PROFESSIONAL with an EDUCATION and not some dumbass with a pickup, toolbox or TV show....
Ron, correct. Think if it this way... the average house has around a 3 ton AC system, that requires around 1200cfm. If you were to install this so that only half the vents open on a call for cooling you would freeze you evap coil (indoor coil), or in heating, your system would bounce off the high limit, this is not a good design. You'll end up spending more money to run the system and you'll end up damaging it. Further more, lets say you have a 3 ton system and you have it setup so your bedroom is one zone. You would be paying to run a 3 ton system to cool one room. it's not cost effective.
Mark Woodworth I agree and you are correct. They skimmed over the topic in this "pretty typical" with this bozo from TV land. He "works" on these systems yet, every manufacturer in the world requires separate drains for heat and cool... Even Goodman... Tho this stem common drains both to one, not to mention not even a little to anyone's code. Maybe the thermostat should just be used and the system corrected. Furnace would tip out on limit and the ac would freeze and thermostatic operation is still based on the the area where it's located... If it's in a zone that's closed the rest of the house would suffer. This system they are selling is a baaaaad idea
We have been zoning hot water and steam heat since it's inception. And we have been zoning commercial air systems for years. It is about time to see residential scorched air get zoned.
use a Variable Air Volume system. it will detect the temp in the room and adjust the motor and pump so that u only get the required airflow and coolant circulation
@@strategygalactic well how many vents do you have? Someone was saying the system would cost them over $4000. Plus batteries and the outlet sensors look kinda bad.
OMG.... Where can I buy this. I just bought a new home, with 3 huge rooms and a massive master bedroom, large loft, huge living room.... lets just say lots of space. But I can't understand for the life of me how the builder put in a central heat/cooling system that is not zoned. So the rooms are either too hot or too cold with no way of adjusting room by room. I got a $16K quote form an HVAC company to redo the system with zones. And, this issue is causing me to burn through a 500gal propane tank in as little as 2-3 months. Your website is not working, how can I get this system?
100 dollars per vent isn't low enough cost to justify manually closing each vent. Is this a novelty price or actual cost of R&D plus materials with a slight mark-up for profit?
The other option is to harvest the airflow energy and store it in rechargeable batteries. You'd only need to harvest once in a while and never replace batteries.
You could make your own if you are that interested. Been using this system for about two years and have had to replace batteries in only 1 of my 12 vents. Though using a voltmeter I suspect I am going to have to go through and replace them all soon. My biggest complaint is they should have a NiMH setting so I can use rechargeable batteries. Five volts and more Ah's should work just fine. The issue is they immediately start saying the batteries need replacement. The one vent I replaced is working, but I can't really tell if it need replacement until the vent drops off line.
@@nicalicious3002 Try putting in a multizone system in an older home and you change your mind. Even with R40 in my attic in the summer my bedrooms get hot and if I run my AC for my upstairs then my downstairs are ice cold. BTW, the cost of a multzone can easily be $10K. I spent $2300 and my house is MUCH better room to room. I only wish they had sensors that don't have to be plugged in, a separate battery sensor I could put anywhere in the room. In my house an outside outlet is way too hot or cold and many of the inside outlets are next to cavities with the HVAC so the temps aren't right. The system seems to figure it out but during Spring and Fall there is a bit of a relearning period. Plus if you are going to put a USB outlet in a unit make sure it can do 2 amps per USB plug. This beats the crap out manual vent control during the summer because the sun moves from front to back of my house and I would be running around several times a day adjusting vents. Winter not so much. Costs are lower purchased as a house upgrade.
but what motor should the furnace have.? regular psc motor?? would closing registers over pressurize duct work? what about a closed register getting to cold and creating humidity problems? come on people don't just buy products without asking your contractor
I really like what I see but I would rather have a thermostat in each room. Apps are great but if you have a guest in the room or a renter you may not want them to be able to control your whole house. Any chance you will convert that little plug in box to also control the temp like the app from the room? Is there a way to give someone control of just one room with the app? This would be especially handy if someone is having a guest. Does your system account for AC systems that have dual fan speeds? My last question is are you going to have any round ceiling vents? I know this is typically a commercial vent but I have them in my home. THANK YOU!
Why do I have to use a costly hvac contractor to install this thing if it's just replacing face plates- there are no links to buy or cost on your website. Keen smart vents appear to do the same thing but can be handled by the DIY enthusiast. Frustrating when companies inflate costs by maintaining archaic distribution channels.
I install cable, phone, internet and security systems with zigbee based sensors and thermostats everyday. My whole house is ran on zigbee/z-wave devices and communication. I refuse to pay somebody to install 7 platic motorized vents, 6 plug in sensors and a hub to my 24p gig switch. If this does not have a self install kit, you've already lost me, I'll just wait for a competitor. Like maybe samsung with a trap thats installed right below existing vent covers.
Insurance companies forbid selling HVAC equipment. They found out the consumer goes after the deep pockets which is the wholesaler/manufacturer. It takes years to get proficient at HVAC and most people won't spend the time or money learning, so they can do a good, safe job. Manufacturers state in their warranty that if bought over the internet there is no warranty. Again, some DIY did something he thought was smart, linear, logical and wrong. Thats why training is essential. Which is why it is as it is. The liability selling to the untrained is higher than the gain/profit from selling. So that may seem stuck up to you but it's basic survival sense and protection from people doing things they haven't the training or equipment to be messing with. To put in a furnace or air conditioner is a minimum of $1000 in tools. The training is a lot more. So who can install it cheaper? You with the tool and training costs for one job or us with many jobs and admittedly overhead to spread over multiple jobs? And dare I say the tradesman insurance in case of trouble. Of which the insurance companies aren't gonna sell to you either. You're welcome to do your own stuff but if you burn/blow your own house down don't whine when they tell you your home insurance doesn't cover it. Zoning for the reasons stated is a bad idea. I like what the guy said and I'll be looking at this product. The HVAC industry needs as many rocket scientists as we can get. :-)
Mykel Hardin Ah yess, it’s DIYrs who make me the most profitable. They see some video such as this, they try it themselves and sooner or later call me to fix it. That being said . . . . . I cannot blame them. Some of the quotes I have seen from residential companies scare even me. There’s stuff that can be fixed (by the homeowner, even) and these companies are quoting a full furnace replacement. It’s insane!!!! Often times if I know it is going to cost an arm and a leg I advise shopping online for the parts. The liability is all on the homeowner, but he can save some money. On the commercial side, it’s a bit different. You said you’ve installed two 5-ton units. That fairly straight forward. And if you can do it, by all means. I do work for a marijuana growth facility with chilled water systems and heat recovery systems that are required by the EPA. Systems that require extreme humidity and temperature control in WA. Sometimes it is very expensive simply because of the liability. Adding a rooftop unit without a structural engineers blessing can end an HVAC company. Creating mold due to a poor install can cause a serious lawsuit.
All in all, I figured it was too good to be true if they just sold the equipment. They can also be wary of where their brand ends. If various DIYers install this system wrong, the credibility of the system falls and they don’t a profit on their product. Either, I really wish they would offer to sell the equipment straight to the homeowner.
Mykel Hardin Oh yes. Mini-Splits are easy to install. But they are peculiar, too. However, having the right tools alone puts you a step ahead of many HVAC installers. Using the flaring tool they use for plumbing, using the wrong gauge of wire for communication, not using a torque wrench on the flares, not placing the system on a vacuum down to 500 microns . . . . . . . . all rather simple practices that are ignored by many who have been doing HVAC for a long time, have resulted in service call backs. Most home installs are rather simple. If you have the tools, that is . . . lol
Love the idea and the ingenuity. However, this seems like a bandaid. If you have drafty areas of the home or areas that are colder and hotter, your house isn’t performing properly. I feel like if you fix the root of the problem, there is no upkeep to that (replacing batteries, etc.), no daily monitoring on an app, and your home would be much more energy efficient.
The register doesn’t normally fully seal them to keep the flow properly that’s why you can’t shut them all otherwise error will activate by the hub and your smartphone will not let you close all of them..
So how do I get this system? Does it save energy or just regulate your home? Closing registers never made sense to me because the heat and or air still goes to the register, so How does that save money?
Travis They never say it saves money except that it prolongs the life of the HVAC unit because it promotes consistant airflow. But the system is mostly to regulate temperature and make the house comfortable, not to save money.
Travis This product seems more about comfort than frugality but it can also save some money. A forced air furnace creates a given amount of heat (hot air) in a given amount of time. If a register is closed and that area is closed (by a door), less hot air is needed to heat the remainder of the house. So the furnace can run for less time. As was mentioned, electronic dampers directly off the trunk are more effective because none of the heat is 'wasted' in the dead end branch. In my opinion, this system would have more promise if it were connected to the furnace (or a thermostat) similarly to how electric dampers are. With this system, from work you could set your living room to be 72 but if you have a traditional (non Internet connected) thermostat and it is not set to the correct temperature, this system does not work.
Dipul, I really need a solution that allows me to pull colder outside air through my home when the outside temperature is less than or equal to the internal desired temp. Perhaps a whole house fan integration with damper controlled fresh air intakes. Opening a closing windows for a whole house fan is both inconvenient and not secure.
I like these. Do they work with ECM motors that ramp up and down? Also, do they work with 2 -wire Daikin SkyAir and VRV Series HVAC equipment which is a specialty brand I provide for my customers?
I just doubt this will make much difference:( The hub is not synced with the thermostat, so there are two control points. If the thermostat does not provide enough air flow, then the room temperature won't be controlled by the sensor effectively....
After reading all of the comments from the so-called experts on HVAC I have just one question. If closing the supply vents will destroy the blower motor hit the limits in the furnace/ac unit etc., etc, why do I have manual controls on the all the vents in my home that allow me to do that very thing. With the room zoning controls, I can now centrally control programmatically via wi-fi what I was able to control manually.
Your manually controlled registers are never meant to close 100%, they get adjusted at the manual takeoff dampers at the A/H main supply. These auto damper type do. Big difference.
Chances are mostly likely you'd never close all the dampers on two or more floors.... in fact, chances of you closing 50% of all your dampers is pretty slim but having an automated system do this is possible especially if it malfunctions due to inconsistent connectivity. Also remember that closing vents will put back pressure to destroy the blower motor only if done in a LONG TERM fashion.... you'd likely freeze or boil well before letting it get that bad in your home which means you'd open vents.
It's one of the better ideas I've seen in a while! How much they cost of a house. Too bad that they is no retail site, seems very easy to install but no info where to buy it from!
Being in construction for 45 yrs and a licensed contractor I would buy and install if system was available. I won't pay what would be a significant price hike for an HVAC contractor to install some vents. I can't even get an idea of the price because that info will impact what the contractors can charge if we the consumer new the prices, not a good way to do business. I understand there are homeowners that need an installer and that's fine. They should be available to purchase online and I think you will loose a lot of sales because of that.
Ian- they dont need every tom, dick and harry installing this and then having to support the product because people 'think' they know what they're doing. I can see a whole lot of problems with this, having a network of contractors that understand the product and can hook it up problem free is the way to go.
This is good idea, , have a question when these dampers close it increases static pressure in system the return is large bringing in air and now say 3 register are 50% ,1 is 70% how is VS blower going to adjust to airflow, without relief damper to make static adjustment??
I don't see a variable speed hvac system that speeds up and slows down according to need Trane builds a really nice true variable speed system that even slows down the compressor to keep the same speed as blower so when one zone isn't calling it compensates with speed of compressor and blower so you don't burn the compressor or blower motor up
No mention of costs on the video. Their website reveals they won't sell the hardware - you must have it installed by their "pros". I would suspect an average system to be upwards of 2 grand. I can't see why adjusting your existing floor dampers manually to balance each room wouldn't work almost as well.
There is currently nothing as easy without hiring a pro to explore around your roof to do this. It is plug and play. I definitely want zoning without the high costs and hassle of outside contracting.
Hi Dipul, Ecovent adjusts the vents to balance each rooms temperature. Before Ecovent, people were doing this manually for years. Floor vents have adjustable louvers for a reason. It sounds to me like you're trying to scare people into buying this overpriced system. I'm guessing the people that buy Ecovent also buy automatic trash-cans, soap dispensers and smart-phone controlled toilet seats - if there is such a thing. Oh yeah, and if my bedroom is too cold or hot compared to other rooms, I will adjust the floor vents myself.
It will kill the system. You’ll get improper air flow leaving the furnace and if like he said the vents adjust according to air flow that means they open up slightly which defeats the purpose of having them in the first place.
Dipul Patel You are not selling these on your website. No prices. Please tell me you are not having these available through 3rd party installation ONLY!!! GIVE US PRICES!
@@proverbs2life They have helped my 1950 house out! Much more comfortable. In the summer the vents downstairs are closed and the AC is running keeping the upstairs cool. During the winter I don't have cold rooms and hot rooms all over the house. BTW, not associated with these guys except by purchase. I just wish I could contact them. Keene bought them and buying their product is far harder. I am looking to upgrade my son's new 1948 house!
Here's the problem with this idea. Dampening air flow anywhere other than the main trunk line is futile. Anyone who understands air balancing knows that maintaining main trunk static pressure is crucial for adequate air flows. This can be done if dampening is occurring at the end of main trunk and at the beginning of each zone branch. There should also be a modulating bypass damper installed linked to network for those days when low demand will cause low flow issues.
It looks rather plug n' play so why do I need a contractor to install it? Can you also give a ball park cost for a typical 2000 sq ft two story house? Thanks. A great looking idea unless it is cost prohibitive.
I think Richard is a personable and generally knowledgeable guy, but sometimes I think he reads from a script that has not been really totally checked out.
I mean it sounds like a great idea but the thing is its gotta connect to a internet box which not every home has and that's a big no for more buyers not to mention of people can hack into it
In this earlier EcoVent RUclips video from Aug 2015 (ruclips.net/video/hbx8sD4lkDo/видео.html), they mention the cost of $1800 for a 4-bedroom house (9 rooms total). They also mention "a couple hundred per room". And lastly, they said they sold these systems to customers directly and their customers installed them with no professional installation needed. Today, they insist on professional installation only and don't mention any prices on their website. For those that don't have smart phones or those that would rather use a computer to control the system, is there a program (app) for home computers ?
Attention public. You don't need zoning. It causes more problems than any benefits you might get from. Been doing HVAC for more than 30 years and have never seen a zoning system that really worked properly. You are far better off with one thermostat controlling the whole house.
I do t agree had a 2700 foot house had two zones and two thermostats worked great. My mother in law kept her area hot we had air. Now living In a 3750 square foot house one thermostat. Basement freezing and first floor not bad, upstairs hot. We have to keep the air low just too get the top two floors cool and you freeze I. Basement. Any good ideas?
If you ductwork is not sufficient enough and you have not enough cooling or heating, how is this going to help? This just modulates the dampers to cut off heating or cooling. If a room is too cold in the wintertime, because your ductwork is not sized right, this is going to do nothing.
I am curious about this product, I have an older home that is a split level and there is a big temperature difference between the upstairs and the down stairs. I am concerned that the lines running to the upstairs rooms are actually to small as they are only 4 inch round ducts and of course not insulated. could this help in a case like this where the downstairs gets cold or hot and the upstairs gets hot or cold. I recently had blown in insulation in the attic and I have reinsulated the outside wall and spray foamed the corners.
sensors used in missles defence.,. lol i love how they upsale a 30 cent sensor.. military sensors are thousands of dollars redundancy your using a freaking arduino temp and moisture sensor 99cents on ebay dont lie bro... dont push a product that clearly anyone can do
Perhaps it's because the sensors used by Uncle Sam have to be rated for ballistic missile use? Arduino sensors are just as good for the job intended. I use them all the time.
Unfortunately coming from the heating and cooling industry, I know this product may seem like it works, but in fact it may still cause furnace and AC issues. Remember!!!! The duct work is sized for the furnace and vise Versa. Closing one vent or duct is NOT good. This thing may close 2, 4,5 or all but one register may cause huge issues!!!!
If room temperature is inconsistent, the original duct work and registers and load calc were not designed properly. If you shut off rooms, you alter the static pressure in the system and further screw up the air flow, and also reduce the efficiency of the system. Go back to rocket making, this is not your field. It takes years and a lot of study to become a good HVAC person.
After this system is installed and all the vent dampers are automatically adjusted, do they change from day-to-day or season to season ? I was thinking about this and they do probably change if you open or close a door to a room and may also change when switching from heating to cooling. If someone were to balance the floor vents manually using a thermometer in each room and being careful not to completely close more than 1 vent, which increases back pressure, I would think the need for this expensive system could be eliminated. If you have a 10 degree or more difference between rooms, your home's duct work was improperly installed. Using a damper of any sort increases back pressure.
You are correct Glenn. Homeowners need to hire the right professional to figure out their HVAC issue after inspecting the whole system not mask over it by putting in the ecovents first.
Well, sort of. The system would change from heating to cooling automatically, just like programable thermostats. You want 68-72 degrees in the living room. If you open the door and the space gets up to 74 degrees, system goes into cooling. While it is true that proper air balancing make all the difference in most setups, you have to remember; -most homes are chain-mailed, meaning not much engineering planning is put into the system. (Unlike hospitals or other commercial settings) -even if properly balance, the amount an intensity of heat sources changes things; too many computers in one room, or too many windows, extra hot. In truth, a very expensive system is necessary if you want to zone any place. SPECIALLY post installation. That’s the beauty of this system. But as with anything, it will not replace the efficiency of a properly planned zoning system.
One of the main issues all zoning systems have to overcome is trying to vary the airflow volume, when most residential HVAC equipment is constant volume. A true variable volume system has equipment designed to run on a wide range of airflow. There is high end residential equipment that is variable volume, with modulating heating and cooling. These high end systems, with variable capacity work well with zoning systems.
Guy would make a killing if he would sell this off to NEST to integrate with their learning thermostats and temp sensors.

When the main thermostat is not calling for cooling/heating, how does the register or hub energize the cooling/heating for the other zones?
This is a phenomenal system ... I’ve watched about 20 vids on hvac and all of them were such garbage but this system looks amazing
Just curious. Are you an HVAC tech?

seems like its easier to install since you don't have to go in the attic and install wiring or pneumatic hoses .etc.

So, you solve one problem with your cold bedroom but created another by having the furnace run longer. A poorly insulated home or inadequate system is very hard to overcome. You're not going to push much more cfm through ductwork that is designed incorrectly. Seems like a neat idea but doesn't solve all the issues. Should be a way for the hub to communicate with the heating and cooling system as well.
zimsjeep m
you would disable the original t-stat.
What doesn't make sense is before you can "damper" the air to the registers, you have to still fill the pipe, you lose pressure and velocity. Correctly done, the dampers would be at the trunk line and not at the end of the run. There is NO easy fix for a poorly designed ducting system period. These "how to" shows make everyone that has heat/cool issues and a credit card poor suckers. Best advice: if your homes heating and air is not doing the job.... Don't watch you tube videos... Call a PROFESSIONAL with an EDUCATION and not some dumbass with a pickup, toolbox or TV show....
Ron, correct. Think if it this way... the average house has around a 3 ton AC system, that requires around 1200cfm. If you were to install this so that only half the vents open on a call for cooling you would freeze you evap coil (indoor coil), or in heating, your system would bounce off the high limit, this is not a good design. You'll end up spending more money to run the system and you'll end up damaging it. Further more, lets say you have a 3 ton system and you have it setup so your bedroom is one zone. You would be paying to run a 3 ton system to cool one room. it's not cost effective.
Mark Woodworth I agree and you are correct. They skimmed over the topic in this "pretty typical" with this bozo from TV land. He "works" on these systems yet, every manufacturer in the world requires separate drains for heat and cool... Even Goodman... Tho this stem common drains both to one, not to mention not even a little to anyone's code. Maybe the thermostat should just be used and the system corrected. Furnace would tip out on limit and the ac would freeze and thermostatic operation is still based on the the area where it's located... If it's in a zone that's closed the rest of the house would suffer. This system they are selling is a baaaaad idea
We have been zoning hot water and steam heat since it's inception. And we have been zoning commercial air systems for years. It is about time to see residential scorched air get zoned.
Of course, but within the parameters of static and dynamic resistance permitted by the blower motors in the air handlers.
Great info. From where I can buy this system? The link in the description is not working.
Thanks.
they probably went out of business because this is mildly jank
Take my money!!!

use a Variable Air Volume system. it will detect the temp in the room and adjust the motor and pump so that u only get the required airflow and coolant circulation
that costs over 5 grand
@@strategygalactic well how many vents do you have? Someone was saying the system would cost them over $4000. Plus batteries and the outlet sensors look kinda bad.
that could be zoned?
What’s the brand of the smart vent system? Where can you buy it? There’s no mention at all.
What is the product name and where can I get it
Where do I get this?
THIS GUY IS A GENIUS!!!!!!🤗🤗🤗
OMG.... Where can I buy this. I just bought a new home, with 3 huge rooms and a massive master bedroom, large loft, huge living room.... lets just say lots of space. But I can't understand for the life of me how the builder put in a central heat/cooling system that is not zoned. So the rooms are either too hot or too cold with no way of adjusting room by room. I got a $16K quote form an HVAC company to redo the system with zones. And, this issue is causing me to burn through a 500gal propane tank in as little as 2-3 months. Your website is not working, how can I get this system?
Wow! I'm sold.
Yes Patel! Have him show you the moneyyyyy!
Sucker born every minute.
It would be nice if you could hardwire it with a transformer instead of using batteries.
100 dollars per vent isn't low enough cost to justify manually closing each vent. Is this a novelty price or actual cost of R&D plus materials with a slight mark-up for profit?
The other option is to harvest the airflow energy and store it in rechargeable batteries. You'd only need to harvest once in a while and never replace batteries.
You can use a transformer. You need to be able to convert the ac into dc using some sort of rectifier. It's more work than what it's worth.
You could make your own if you are that interested. Been using this system for about two years and have had to replace batteries in only 1 of my 12 vents. Though using a voltmeter I suspect I am going to have to go through and replace them all soon. My biggest complaint is they should have a NiMH setting so I can use rechargeable batteries. Five volts and more Ah's should work just fine. The issue is they immediately start saying the batteries need replacement. The one vent I replaced is working, but I can't really tell if it need replacement until the vent drops off line.
@@nicalicious3002 Try putting in a multizone system in an older home and you change your mind. Even with R40 in my attic in the summer my bedrooms get hot and if I run my AC for my upstairs then my downstairs are ice cold. BTW, the cost of a multzone can easily be $10K. I spent $2300 and my house is MUCH better room to room. I only wish they had sensors that don't have to be plugged in, a separate battery sensor I could put anywhere in the room. In my house an outside outlet is way too hot or cold and many of the inside outlets are next to cavities with the HVAC so the temps aren't right. The system seems to figure it out but during Spring and Fall there is a bit of a relearning period. Plus if you are going to put a USB outlet in a unit make sure it can do 2 amps per USB plug. This beats the crap out manual vent control during the summer because the sun moves from front to back of my house and I would be running around several times a day adjusting vents. Winter not so much. Costs are lower purchased as a house upgrade.
Do you need a bypass damper in this case?
I was thunkning the same thing
Now combine this with nest
but what motor should the furnace have.? regular psc motor?? would closing registers over pressurize duct work? what about a closed register getting to cold and creating humidity problems? come on people don't just buy products without asking your contractor
I can imagine all kinds of room to room pressurization issues in the home with supply/returning balancing
The link doesn't work. Also does this require smart control for the hvac, and how does this tell the hvac to shut off?
I’m thinking zone by zone is a little too expensive for the benefit.. just my opinion.
I don't see this as too thrilling. If you can adjust the registers to solve the problem then you don't actually have a problem.
I really like what I see but I would rather have a thermostat in each room. Apps are great but if you have a guest in the room or a renter you may not want them to be able to control your whole house. Any chance you will convert that little plug in box to also control the temp like the app from the room? Is there a way to give someone control of just one room with the app? This would be especially handy if someone is having a guest. Does your system account for AC systems that have dual fan speeds? My last question is are you going to have any round ceiling vents? I know this is typically a commercial vent but I have them in my home. THANK YOU!
Can someone please share the name of this product????
Love the Klipsch speakers.
so where can we buy them????
Any way to integrate it with smartthings? If not, I think your market will greatly expand if you make the individual registers compatible.
Would like them to retrofit a variable fan control to the furnace as part of their system.
Wonder what this does to static pressure when several vents are closed off but the system is still running
The hub will preserve airflow via programming.
You wonder that, do you? Smart guy.
Why do I have to use a costly hvac contractor to install this thing if it's just replacing face plates- there are no links to buy or cost on your website. Keen smart vents appear to do the same thing but can be handled by the DIY enthusiast. Frustrating when companies inflate costs by maintaining archaic distribution channels.
I install cable, phone, internet and security systems with zigbee based sensors and thermostats everyday. My whole house is ran on zigbee/z-wave devices and communication. I refuse to pay somebody to install 7 platic motorized vents, 6 plug in sensors and a hub to my 24p gig switch. If this does not have a self install kit, you've already lost me, I'll just wait for a competitor. Like maybe samsung with a trap thats installed right below existing vent covers.
Insurance companies forbid selling HVAC equipment. They found out the consumer goes after the deep pockets which is the wholesaler/manufacturer.
It takes years to get proficient at HVAC and most people won't spend the time or money learning, so they can do a good, safe job.
Manufacturers state in their warranty that if bought over the internet there is no warranty. Again, some DIY did something he thought was smart, linear, logical and wrong. Thats why training is essential. Which is why it is as it is. The liability selling to the untrained is higher than the gain/profit from selling. So that may seem stuck up to you but it's basic survival sense and protection from people doing things they haven't the training or equipment to be messing with. To put in a furnace or air conditioner is a minimum of $1000 in tools. The training is a lot more. So who can install it cheaper? You with the tool and training costs for one job or us with many jobs and admittedly overhead to spread over multiple jobs?
And dare I say the tradesman insurance in case of trouble. Of which the insurance companies aren't gonna sell to you either. You're welcome to do your own stuff but if you burn/blow your own house down don't whine when they tell you your home insurance doesn't cover it.
Zoning for the reasons stated is a bad idea. I like what the guy said and I'll be looking at this product. The HVAC industry needs as many rocket scientists as we can get. :-)
Mykel Hardin
Ah yess, it’s DIYrs who make me the most profitable.
They see some video such as this, they try it themselves and sooner or later call me to fix it.
That being said . . . . . I cannot blame them.
Some of the quotes I have seen from residential companies scare even me.
There’s stuff that can be fixed (by the homeowner, even) and these companies are quoting a full furnace replacement.
It’s insane!!!!
Often times if I know it is going to cost an arm and a leg I advise shopping online for the parts. The liability is all on the homeowner, but he can save some money.
On the commercial side, it’s a bit different.
You said you’ve installed two 5-ton units.
That fairly straight forward. And if you can do it, by all means.
I do work for a marijuana growth facility with chilled water systems and heat recovery systems that are required by the EPA.
Systems that require extreme humidity and temperature control in WA.
Sometimes it is very expensive simply because of the liability.
Adding a rooftop unit without a structural engineers blessing can end an HVAC company.
Creating mold due to a poor install can cause a serious lawsuit.
All in all, I figured it was too good to be true if they just sold the equipment.
They can also be wary of where their brand ends.
If various DIYers install this system wrong, the credibility of the system falls and they don’t a profit on their product.
Either, I really wish they would offer to sell the equipment straight to the homeowner.
Mykel Hardin
Oh yes. Mini-Splits are easy to install.
But they are peculiar, too.
However, having the right tools alone puts you a step ahead of many HVAC installers.
Using the flaring tool they use for plumbing, using the wrong gauge of wire for communication, not using a torque wrench on the flares, not placing the system on a vacuum down to 500 microns . . . .
. . . . all rather simple practices that are ignored by many who have been doing HVAC for a long time, have resulted in service call backs.
Most home installs are rather simple.
If you have the tools, that is . . . lol
Love the idea and the ingenuity. However, this seems like a bandaid. If you have drafty areas of the home or areas that are colder and hotter, your house isn’t performing properly. I feel like if you fix the root of the problem, there is no upkeep to that (replacing batteries, etc.), no daily monitoring on an app, and your home would be much more energy efficient.
can this product work on a system that is already zoned?
What is the name of the Co. Highlighted are they still in business?
The register doesn’t normally fully seal them to keep the flow properly that’s why you can’t shut them all otherwise error will activate by the hub and your smartphone will not let you close all of them..
A closed register "whistling" TO the HVAC graveyard? The sound will actually be your system screaming for help.
They still make that wind noise when one vent is close.
Loved it, Awesome Video.
So how do I get this system? Does it save energy or just regulate your home? Closing registers never made sense to me because the heat and or air still goes to the register, so How does that save money?
Travis They never say it saves money except that it prolongs the life of the HVAC unit because it promotes consistant airflow. But the system is mostly to regulate temperature and make the house comfortable, not to save money.
Travis
This product seems more about comfort than frugality but it can also save some money.
A forced air furnace creates a given amount of heat (hot air) in a given amount of time. If a register is closed and that area is closed (by a door), less hot air is needed to heat the remainder of the house. So the furnace can run for less time.
As was mentioned, electronic dampers directly off the trunk are more effective because none of the heat is 'wasted' in the dead end branch.
In my opinion, this system would have more promise if it were connected to the furnace (or a thermostat) similarly to how electric dampers are.
With this system, from work you could set your living room to be 72 but if you have a traditional (non Internet connected) thermostat and it is not set to the correct temperature, this system does not work.
@@Maxid1 It does the opposite of prolonging the life of a HVAC system.
What name that register ?
Dipul, I really need a solution that allows me to pull colder outside air through my home when the outside temperature is less than or equal to the internal desired temp. Perhaps a whole house fan integration with damper controlled fresh air intakes. Opening a closing windows for a whole house fan is both inconvenient and not secure.
How to you purchase these?
is there an active resource link as Id love to learn more about the product featured..
Where can I actually buy this system?
This is great. Where can you buy this?
That's so cool! I wish we had this here in Brazil!
This system works with any forced air furnace?
I like these. Do they work with ECM motors that ramp up and down? Also, do they work with 2 -wire Daikin SkyAir and VRV Series HVAC equipment which is a specialty brand I provide for my customers?
Are there any hvac zone systems that are easy to control with a smart phone?
will it work without internet???
I just doubt this will make much difference:(
The hub is not synced with the thermostat, so there are two control points.
If the thermostat does not provide enough air flow, then the room temperature won't be controlled by the sensor effectively....
that's very cool ,make the job is very easy.
After reading all of the comments from the so-called experts on HVAC I have just one question. If closing the supply vents will destroy the blower motor hit the limits in the furnace/ac unit etc., etc, why do I have manual controls on the all the vents in my home that allow me to do that very thing. With the room zoning controls, I can now centrally control programmatically via wi-fi what I was able to control manually.
Your manually controlled registers are never meant to close 100%, they get adjusted at the manual takeoff dampers at the A/H main supply. These auto damper type do. Big difference.
Chances are mostly likely you'd never close all the dampers on two or more floors.... in fact, chances of you closing 50% of all your dampers is pretty slim but having an automated system do this is possible especially if it malfunctions due to inconsistent connectivity. Also remember that closing vents will put back pressure to destroy the blower motor only if done in a LONG TERM fashion.... you'd likely freeze or boil well before letting it get that bad in your home which means you'd open vents.
It's one of the better ideas I've seen in a while! How much they cost of a house. Too bad that they is no retail site, seems very easy to install but no info where to buy it from!
Being in construction for 45 yrs and a licensed contractor I would buy and install if system was available. I won't pay what would be a significant price hike for an HVAC contractor to install some vents. I can't even get an idea of the price because that info will impact what the contractors can charge if we the consumer new the prices, not a good way to do business. I understand there are homeowners that need an installer and that's fine. They should be available to purchase online and I think you will loose a lot of sales because of that.
Ian Mather I totally agree...
Ian- they dont need every tom, dick and harry installing this and then having to support the product because people 'think' they know what they're doing. I can see a whole lot of problems with this, having a network of contractors that understand the product and can hook it up problem free is the way to go.
I really wish there was a way to hard wire the vents not a big of the batterys
This is good idea, , have a question when these dampers close it increases static pressure in system the return is large bringing in air and now say 3 register are 50% ,1 is 70% how is VS blower going to adjust to airflow, without relief damper to make static adjustment??
yep, the fan works just as hard to try and force air through ducts that are closed.
only way system wont work as hard is if it is closed off before airflow enters the ducts
What about the Suction vents?
I don't see a variable speed hvac system that speeds up and slows down according to need Trane builds a really nice true variable speed system that even slows down the compressor to keep the same speed as blower so when one zone isn't calling it compensates with speed of compressor and blower so you don't burn the compressor or blower motor up
No mention of costs on the video. Their website reveals they won't sell the hardware - you must have it installed by their "pros". I would suspect an average system to be upwards of 2 grand. I can't see why adjusting your existing floor dampers manually to balance each room wouldn't work almost as well.
I do not see pricing on their website. These should be easy DIY kits.
Right on the money. It is not hard to install. I guess this is where their money will go.
The starting price is $2,500 (I received an email).
A bit too expensive for me. Maybe they are that good!
There is currently nothing as easy without hiring a pro to explore around your roof to do this.
It is plug and play. I definitely want zoning without the high costs and hassle of outside contracting.
Hi Dipul, Ecovent adjusts the vents to balance each rooms temperature. Before Ecovent, people were doing this manually for years. Floor vents have adjustable louvers for a reason. It sounds to me like you're trying to scare people into buying this overpriced system. I'm guessing the people that buy Ecovent also buy automatic trash-cans, soap dispensers and smart-phone controlled toilet seats - if there is such a thing. Oh yeah, and if my bedroom is too cold or hot compared to other rooms, I will adjust the floor vents myself.
Don’t you need a variable speed HVAC equipment for this. I don’t see how this would not kill the system if you close off vents
Hew says it won't lol
It will kill the system. You’ll get improper air flow leaving the furnace and if like he said the vents adjust according to air flow that means they open up slightly which defeats the purpose of having them in the first place.
@@hvacguy11 No it won't. Mine has been working perfectly for 4 years now. No issues and I have my system checked twice a year.

@@proverbs2life They have helped my 1950 house out! Much more comfortable. In the summer the vents downstairs are closed and the AC is running keeping the upstairs cool.

Keene bought them and buying their product is far harder. I am looking to upgrade my son's new 1948 house!
Here's the problem with this idea. Dampening air flow anywhere other than the main trunk line is futile. Anyone who understands air balancing knows that maintaining main trunk static pressure is crucial for adequate air flows. This can be done if dampening is occurring at the end of main trunk and at the beginning of each zone branch. There should also be a modulating bypass damper installed linked to network for those days when low demand will cause low flow issues.
I agree, however I would add a reverberating neuralizer with mutating capacity. You can buy them from Jeeves.

Attention public. You don't need zoning. It causes more problems than any benefits you might get from. Been doing HVAC for more than 30 years and have never seen a zoning system that really worked properly. You are far better off with one thermostat controlling the whole house.
Agreed. Zoning is for big buildings, not an average house. Complete waste here.
@@gangisspawn1 Yep , Last week I was in a house working on a zone system that was only 2.5 tons. And I am just shaking my head.
I do t agree had a 2700 foot house had two zones and two thermostats worked great. My mother in law kept her area hot we had air. Now living In a 3750 square foot house one thermostat. Basement freezing and first floor not bad, upstairs hot. We have to keep the air low just too get the top two floors cool and you freeze I. Basement. Any good ideas?
If you ductwork is not sufficient enough and you have not enough cooling or heating, how is this going to help?
This just modulates the dampers to cut off heating or cooling. If a room is too cold in the wintertime, because your ductwork is not sized right, this is going to do nothing.
Answer: Fix your HVAC system ducting first.
I am curious about this product, I have an older home that is a split level and there is a big temperature difference between the upstairs and the down stairs. I am concerned that the lines running to the upstairs rooms are actually to small as they are only 4 inch round ducts and of course not insulated. could this help in a case like this where the downstairs gets cold or hot and the upstairs gets hot or cold. I recently had blown in insulation in the attic and I have reinsulated the outside wall and spray foamed the corners.
Yes Daniel,
Buy ecovent first, then we will help you fix all your other problems.
Trust us..........please.
sensors used in missles defence.,. lol i love how they upsale a 30 cent sensor.. military sensors are thousands of dollars redundancy your using a freaking arduino temp and moisture sensor 99cents on ebay dont lie bro... dont push a product that clearly anyone can do
They probably aren't going to fail. It's just marketing.
Perhaps it's because the sensors used by Uncle Sam have to be rated for ballistic missile use? Arduino sensors are just as good for the job intended. I use them all the time.
Old type of workinq! Now its Better.
Unfortunately coming from the heating and cooling industry, I know this product may seem like it works, but in fact it may still cause furnace and AC issues. Remember!!!! The duct work is sized for the furnace and vise Versa. Closing one vent or duct is NOT good. This thing may close 2, 4,5 or all but one register may cause huge issues!!!!
Too bad, Ecovent no longer has a website and is likely out of business.
What a complicated mess. I manually balanced my system in 30 minutes right after buying my house, and haven’t seen a need to adjust it yet.
That’s great that you can do that. How do you do that?
How much are these?
Systems start at $2500 installed
If room temperature is inconsistent, the original duct work and registers and load calc were not designed properly. If you shut off rooms, you alter the static pressure in the system and further screw up the air flow, and also reduce the efficiency of the system. Go back to rocket making, this is not your field. It takes years and a lot of study to become a good HVAC person.
After this system is installed and all the vent dampers are automatically adjusted, do they change from day-to-day or season to season ? I was thinking about this and they do probably change if you open or close a door to a room and may also change when switching from heating to cooling. If someone were to balance the floor vents manually using a thermometer in each room and being careful not to completely close more than 1 vent, which increases back pressure, I would think the need for this expensive system could be eliminated. If you have a 10 degree or more difference between rooms, your home's duct work was improperly installed. Using a damper of any sort increases back pressure.
You are correct Glenn.
Homeowners need to hire the right professional to figure out their HVAC issue after inspecting the whole system not mask over it by putting in the ecovents first.
Well, sort of.
The system would change from heating to cooling automatically, just like programable thermostats.
You want 68-72 degrees in the living room. If you open the door and the space gets up to 74 degrees, system goes into cooling.
While it is true that proper air balancing make all the difference in most setups, you have to remember;
-most homes are chain-mailed, meaning not much engineering planning is put into the system. (Unlike hospitals or other commercial settings)
-even if properly balance, the amount an intensity of heat sources changes things; too many computers in one room, or too many windows, extra hot.
In truth, a very expensive system is necessary if you want to zone any place.
SPECIALLY post installation.
That’s the beauty of this system.
But as with anything, it will not replace the efficiency of a properly planned zoning system.
My room is hot as hell but to be fair not one missile strike since install!!
that's is amazing
