The HVAC industry wasn’t ready for A2Ls when it launched outside the US, and it still isn’t ready today, the only circumstance when the refrigerants flammability is an issue is when techs aren’t using key best practices when brazing including; recovering into a vacuum, purging with nitrogen after recovering, CUTTING OUT ALL COMPONENTS NOT SWEATING OUT and flowing nitrogen when actively brazing. The problem is 99% of Techs aren’t doing these practices, which is going to result in igniting the refrigerant when brazing under some circumstances. Otherwise A2L refrigerants like R32 and R454B are fine.
I don't like an upside down board you went the wrong way
Jaquar heat pump E02 lack of refrigerant ERROR HOW TO FIX PROBLEM
I'm skeptical, and I'd need to see some real world examples of hot or cold walls skewing temperature readings enough to cost "a fortune"
I really dislike the practice of cutting the vent hole in the drywall and leaving the exposed drywall. Air quality is a much greater priority than ever, we should really be sealing up that drywall so that the dust isn't getting picked up by the vents. And for those that want to try and dismiss that concern, you're indeed incorrect. It is a big deal. Yes, there is a lot of dust within a home, including new construction or remodels, but things should also be cleaned far better to remove as much as possible. In addition, sealing air infiltration points from unconditioned spacing is important and that includes these vents, anyhow. Also, I think extra work should be done when extending a duct to ensure that overlapping insulation doesn't separate. Some tape internally and even a zip tie externally. Some movement or shifting when setting the duct or blowing insulation likely will mess it up, even if you've gone through a lot of effort to create "slack" internally. It also looked like you were going to handle it, but when you taped the duct to the collar, the perforation in the lip is exposed. I would have covered that with the tape. The outer tape isn't enough. For air quality, we're talking about microscopic particulates and fiberglass is not something you want in your lungs. And... some better beer. :) Overall a great video, I think you did a great job, it was just things that I get very nit-picky about. You've performed a great service to the community!
to add, the only difference is to include but not limited to: 1. Its in an attic 2. you're crawling around on rafters 3. it's 100 degrees 4. its dusty, dirty and poor air flow, dead mice, rats and if you're lucky a raccoon 5. it's not at hip height, in a conditioned space and you can reach everything 6. you're swimming in insulation 7. you're wearing long sleeve shirts, mask, dickies trousers 8. You're working on sheetrock 9. Everything you touch is wet, because its 100 degrees and you're sweating on everything 10. Your drill battery dies 11. Your head mounted lamp keep slipping and then the battery dies 12. You're doing this for 3 days straight praying for a cloudy day or rain 13. You're going in and out through a scuttle in a closet 14. The customer wonders why this is taking so long and doesn't like you're playing 5FDP 15. The office gives you "Emergency" calls after you're done for the day because you're on-call 16. The office gives you calls because the customer specifically requests you. 17. The office gives you calls because the on-call guy called in for the day. Yea, okay.
We've been through all of what you have said. That's why duct systems are expensive. (team member)
100 degrees? Must be a crisp fall day in the off season.
My old central ac just stop working. R-22 condenser with a date code of 1989. Compressor finally went. Be hard pressed to get that longevity out of a new unit
Cool idea on the transition box...how do you know how big to make it? My system is 4 ton, 1600cfm but ducted for 1200 cfm, so I need to fix that. I was thinking of feeding 1 - 14" and 2 - 12" flex to 3 different zones of the house and build 3 transition boxes to feed all the room ducts. So...basically 700 and 480 CFM boxes, respectively. I was thinking 1 - 16"x16"x16" cube and 2 - 14"x14"x14" cubes. Would that introduce too much loss in the system?
First; using a cube transition box is not a bad idea however, obtain a duct design done by a professional load calculation company and strictly go by that.
What is the deal with the copper vs aluminum condenser? Why is aluminum better?
Hey great video i learned a lot.. i was taught that insulation and a good contractor that is knowledgeable makes a systems last a long long time…..
Recommended Daikin AC that uses R32 or R410? please help me answer because I want to install AC.
Awesome job gents...enjoy the content, keep it coming!
More to come!
I think the only notable things on the new unit... it is R-32... and the fan blade. The other changes are simply incremental engineering changes that could have happened on a revised R-410a unit. I do think that 15" of overlapped coil is rather odd. Why not more? Why not less? I suspect the driving concern is storing it in a warehouse and shipping; that allows the unit to be slightly smaller which helps in those circumstances. It really doesn't matter for installation. Now the fan blade. That is cool. There are have been two major advances in propellers in the past few decades and I was hoping that they would make their way to our systems: 1. Toroidal blades: this is the innovation I really want to see. they're much more efficient and even quieter, by far. 2. Serrated trailing edge: this is mostly considered a way to make the movement quieter, but noise is the expression of energy, so the quieter it is, the more efficient it is. I'd like to see both. EDIT: So, I replaced my old AC with an ASHP last year when it died. I am really happy with the system. It was just a drop in replacement... I kept my gas furnace as the air handler and for backup heat. A significant contributing factor to the failure of the AC was the zoning system and a failed damper... and a failed temperature sensor in the zoning board. So, I have been to get rid of all of that and just get a 2nd unit for the upstairs. I was initially rather concerned about R-32. I still have some reservations, but I think I am ready for one. I was going to get an identical R-410a ASHP, but with an air handler, since it would be net new. Since it will be for upstairs, I think R-32 makes a lot of sense. The biggest reservation I have about R-32, still, is having it next to my gas burner for the furnace. Since I won't have this for the upstairs unit, R-32 seems like a no brainer. I am in an area where we get extended periods of below zero (fahrenheit) temperatures in late January and early February, so backup heat is super important to me, even though my ASHP seemed to work fine (I had the thermostat set to burn gas when it was below 5F overnight so I didn't wake up to a freezing house in the event that I somehow messed with my install... it was fine). Perhaps my concerns will prove unwarranted with two separate units and the improved performance of R-32.
great educational video!! music + speech = hard to understand...
Sir which is the safest gas for ac inverters
With the open flame, you need to allow the gas to fill the chamber to reach the flame.
Does it make sense to do both?
It could but the clingwrap works just fine.
@@GWAC555 so just doing the cling wrap is sufficient and the other is diminishing return? I have leftover bubble insulation would that work fine as well?
Had a daikin dealer give me some estimates today for 410 and 32 fit systems. they have an incentive now for the 410. im hoping to be able to hold off and get this 32 system you are showing. why didn't the rest of the industry use 32?
GWP on the R454 is lower
We need larger fans for more efficient air flow. More air per kW. We need stacked pump mediums. One medium in the circuit inside/outside and a second medium in an inside/inside configuration. It is heat pumps all the way from absolute zero to the heat of the sun.
Impressed! Great info
The concentration of the r32 was too high to be in the range of explosive mix. Between 13,5 and 27%Vol in air it is explosive. Below and above it's not. Try that again with 20% Vol.mix in Air 🤪
I believe the statement was made that all the thermostats could be calibrated / adjusted for readings. I know at least the Nest thermostat has no adjustment to readings. The Ecobee does. Also, thermostats such as Nest and Ecobee can have their temperature swayed by how long the display is on. I know since I have both. Not sure of the others. Years ago I had a Honeywell LCD that had the option to keep the backlight on low level and it would throw off the reading by a degree or two.
Yes! Great observations.
What do you mean by this video.. Europe is basically canceling R32 very soon
Sensi
What about silicone putty instead of clingwrap? Definitely more insulative, dielectric, won't trap moisture between its layers over time and you shouldn't need to disconnect wiring
Have you done a comparison between R-134a and R-1234yf yet? Id love to see those
Nobody buys R32 if you can buy R290.
This is the reason why.... ruclips.net/video/I04H_irTH24/видео.html
This could be all resolved by just manufactures placing the temperature gauge as an external antenna on the thermostat.
Yes. We know for sure that manufacturers are trying to solve this issue and constantly improving temperature accuracy. Someone will come up with the solution.
My thermostat is in my bedroom and being an ecobee, having the ceiling fan on messes with the algorithm that accounts for the heat it produces. The main reading is always off so I have to set it to ignore the main thermostat and use the room sensors.
So put the thermostat in the center hall, with the least windows. And no direct sun
Loved this video ! I thought of making one like it and now I don’t have to lol my take away is that they are both flammable. Idc about “mildly “ because that’s like saying someone is mildly pregnant. I saw fire on both.
Well said. We all need to be more careful from now on
its difficult to do this when your air handler is in the attic
Your point being? Government Gona do what there Gona do point final!!
Madeline has an absolute dump truck
Before making the change starting at 13:26 (foam in the wall), I urge you to verify that the area between the studs is NOT used for return air. Blocking this flow could alter the temperature in the room that this "duct" is attached to.
The main idea is to seal the wall so that air from the wall cavity does not leak onto the thermostat. “As mentioned above, a low volume of air was circulated in the wall cavity. The team did it in a way that it didn’t affect the air temperature in the studio. The cured foam wasn’t blocking the air circulation at all. Please see the IR photo at the end of the video. It’s clearly visible that the foam behind the wall remained at room temperature (bright orange color), while the surface of the wall was blue, representing a cold wall surface." (team member)
Digital Psychomotor $85.00? YIKES!
Does it matter what it reads What is comfortable matters 🤔
CO2 is the best option for consumer. Been used commercially for decades but will never happen because HVAC industry will lobby governments against it. Gas is obtainable without a license fo $3/lb.
We agree with you!
How about the exploding refrigerators! LOL! Personally, I'm convinced that all this climate change talk is BS and we're all being grifted by the industry so they can develop new expensive garbage to peddle more frequently. R-12, R-22 and R-502 were the best refrigerants ever made and systems lasted decades. Now, you're lucky to get 10 years. It's a shame people are so gullible and just go with the flow and allow these groups to mandate these BS regulations without absolute proof it's necessary and I think history will prove that the climate hoax was just smoke and mirrors for profit. It's the middle of August here in Augusta, Ga. and it's currently 64 degrees at 6:22 am and the high is only going to be around 85. I had hotter summers in the 70's, 80's and 90's.
R32 Flammability Test m.ruclips.net/video/Nnz4ODMyOJ8/видео.html
Evaporator coils are crap today. I'm tired of changing them personally (thank God I'm about to retire), but I wonder if R-32 is flammable enough to ignite in a home where the evap coil pops a leak in a smokers house while they're smoking or lighting up?
I don't believe R-32 will blow up. R-290 (propane) & R600 (butane) definately are. I think R-32 needs a flame source to burn & cannot do a sustain burn by itself.
@@guytech7310excellent information ! R32 needs over 600°C to burn and dies off without a constant ignition source.
Today I did my first R32 mini split system at my company here in Southern California. R410A is officially over. We aren’t going to be buying any more inverters with 410A
What is the pricing difference between the 2 types if same seer 2 rating? Thanks
what are your thoughts on the Daikin thermostats? I heard they can be a problem. ???
very informative and entertaining
Glad you enjoyed it
Thanks for sharing, and I found the information interesting, and I like what you set out to accomplish but you lost your way in the middle. Suggestion: It would have been better if you were consistent with your testing method. The whole time you’re comparing multiple thermostats on the same wall, but then t the end you do you final comparison using a different wall,only one thermostat and the thermostat you used was different then the test thermostats. Additionally you added an extra sensor that wasn’t apart of the original testing.
We are unclear what you mean by "sensor". We used 2 psychrometers as reference. It would be impractical to test the foam method using the original wall that was employed for testing the gaskets on those 8 thermostats, as the wall cavity was hosting thermostat wires. (team member)
The wall trick is clever but common guys, newer thermostats come with sensors that can be programmed to use average the temperature of all sensors or only use the sensors in the occupied rooms. I have an Ecobee and i have it set to disregard its main sensor and only use the room sensors. Pretty sure the nests can do the same thing. I'm interested to learn how accurate those room sensors add ons are, Not the main unit.
This is interesting information. In my case however both my Nest Learning Thermostats are on internal walls so not so affected by wall temps. At least I would assume.
I’ve been and HVAC technician for a long time. I’ve have seen some hack jobs on the field but I’ve never seen any thermostat mounted on exterior walls in my entire life. I would suggest reading the description below. Hot and cold interior wall effect is a real phenomenon and affects large percentage of homes especially older homes. The guys used exaggeration to prove this phenomenon but if the thermostat is only off by one degree it could mean 3-4% increase on the home owner’s energy bill. HVAC companies in U.S. deal with this issue quite frequently. (staff member)
0:49 Great info overall! But the best part (for me) is how none of their microphones are plugged in 😂😂😂.
This would only matter if you had thermostats in each room.
I use nest remote sensors and each nest uses those for temp readings and not the nest device.
The nest thermostats kinda suck.
R290 is the future
