Whole House Ductless Mini Split Walk Through
HTML-код
- Опубликовано: 21 июл 2022
- In this video we walk through a six zone mini split installation in Londonderry, NH. This install is going to cool/heat the whole house (besides the bathrooms). We had to get creative with this install due to limited wall space on exterior walls. In the walk through we explain how we use the basement and other areas like under the deck to hide our lineset and get it to where we need without putting slim duct around the whole house. If you have any questions feel free to ask away in the comments! Thanks for watching.

Thanks for the vid. Well done
Thank you, thanks for watching.
Thanks for the video. I need to replace my broken system.I’m in SC and don’t have a basement. An animal got into the crawl space and tore up all the duct work. I have a two story 2400 sq ft house. I really don’t want lines outside my house.
can minisplit lines be put into the exterior wall instead of outside along the house? My house is old and likely a balloon construction.
Does it work in dry heat weather?
Awesome video I'm in southern NH and debating what direction I should go with mini split or installing ducting
Let us know if we can help! We are located in Derry.
Great video. Thanks. What is the max length a line set can be?
Thanks for watching. Each had has a max line set run of approx. 84 feet.
Hi, how far away can the Condensers be from feet distance from the split unit installation?
Thanks!
What size minisplit would you put in a 288 sq ft tinyhouse with a vaulted ceiling in Texas?
Installed right there where the sun hits them.why?
How much did this project cost?
Do they make smaller units for bathroom and walk-in closets? My home office is 10'x10' and I'm concerned that a mini split would just cycle on and off in the small rooms
The smallest unit I'm aware of across all major brands is a 6k BTU unit. It is tough to make them work for bathrooms, unless you can do a ceiling casette. For your office you'd probably be okay.
Please excuse my sons picture lol curios as to how much noise these make inside/outside the home and if they heat your home as efficiently as the old baseboards. Right now I love how quickly my home gets warm but am definitely considering switching. I have vaulted ceilings and am worried at how well it works to heat the room if they were installed high up.
What's up with those switches?
Instead of using the slim duct on the front of the house for the Livingroom would running inside the wall be an option?
You could do that, if the homeowner wants to go through opening up walls it's definitely an option.
Hi. Where is fresh air coming from with these systems? Is there a separate ducted ventilation system or not required because it's an older house with leaks? If this system was installed on a newer well-insulated house, would they also need a separate ventilation system?
The air handler inside just acts as a fan sucking in air from the top and blowing out hot or cold air out the bottom. They’ve have filters on them that you get to easily by flipping the lid up and pulling them out. Then just blow them off or wash them off with water. Very efficient technology with these modern mini splits systems 👍
If you want fresh air open a window.
Nobody really answered your question! I have a tight home in NE and mini split hvac ... and yes, you would want a heat exchanger venting system for house. I have whole house Fantech Heat Recovery Ventilator.
It's best not to install the unit in direct sunlight or near other heat sources. This will impact the mini split's ability to monitor indoor temperatures and perform efficiently.
Why not ceiling cassettes?
You're welcome
Hi, what us the switch under each head for? Also, do you guys use whole house surge protectors?
The code in new hampshire says you have to have a disconnect at each indoor head (might be changing soon), so that is what the switches are for.
This fellow has very interesting mannerisms. Thanks for the video.
he gets paid for it.
how much would your electricity bill be compared to a traditional split system
I don't have an exact $ figure, but the ductless mini splits are much more efficient than your traditional central air split systems.
@@paultheplumber8665 Ok thank you. Yeah I'm in the trade. I own an HVAC-R Company but i have only seen tests done comparing 1 mini split vs a traditional split system. I want to see what the real difference is between cooling a whole house with a central AC and Mini Split. Im also currently building my house and want to make that decision soon. Ive also thought about a VRF system. Which works very similar to a Ductless Mini Split
@@demented392rt5 I installed 3 inverter type mini splits in my house and turned off the central air this summer. Those three units cool the entire house better and my electric bill went down from $400 to $150. We are in Florida and I put one unit in the master bdrm. It is so nice and comfortable. When we go to bed I turn off the big unit in the living room / kitchen and we can set the bdrm to 70 if we want. We love it. Long term maintenance seems to be a little bit of work as far as cleaning and maintaining but I don't mind at all. It's worth it to me.
Great work 👌👍 my home is about if not less than 1000. sq ft, what's the correct size unit for me in Patchogue, NY?
Thank you 🎉
ps: installed 2021 i own Lennox ductless model # MHA018S4S-1P
I think.its leaking from inside and my floor buckled, i believe it's too small. Don't think this guy knew what he was doing, 3500. + unit . I know nothing about this stuff. I get bullied because im a female, terrible
Hey I was born in Patchogue.
@@michaelwalker3920hi Michael
I was born in the Bronx , grew up in Brentwood
It could be the condensate line is leaking or was not led to exterior properly? The 1.5 ton unit you have should be able to heat & cool around 700-800 sf in NY....so could be undersized if you are more like 900-1000sf? You would want a 2 ton unit if 1000 sf. I would contact the installer and have him check for condensate leak and test for refrigerant leak too. If refrigerant is not 100% it could reduce heating & cooling capacity. Any good reputable HVAC technician could check it out for you for $100 +/- service fee, if you don't have any warranty from initial installer.
I’m in mastic myself and am curious who did your install as I just had the home efficiency experts here yesterday to do an energy audit. The guy was so animated it felt like I was being worked.
Run the lines behind the drywall and not up the exterior wall. That makes it look like such a cheap install.
get some surge protectors on those
What are you talking about?? They are wired through an AC disconnect and then to the panel....
@@C.Double. are you dense? Do you know what a surge protector is?
@@C.Double. Unless you have a Surge Arrestor installed at you AC disconnect or at minimum the Main panel, You will want Surge Protection! I learned the hard way.....lost my minisplit from a power surge or nearby lightning strike (HVAC Technician could not tell which). My outside unit control board and compressor got toasted.....had to replace entire system! Surge protection is cheap insurance at $250 ! Best to put protection between the AC disconnect and the condenser unit.
If you see one of these in person, they look hideous with the lines running all over the house
What was the total cost?
These systems usually cost around 50k installed
@@michaelc9248 50k is a total rip off. And they didn't even install an ICM 493 to protect the equipment.
@@michaelc9248 not even close. With two condensers and 6 heads I could potentially see 25k TOPS. If someone gets quoted more than 20k in my opinion they’re getting quoted based on what they look like they can afford. Zip code quoting we called it in construction. Quote high cuz they’ll easily afford it.
In Texas I can get it for $7k . Mini split I want is like 5k & labor probably $2k or less
@@michaelc9248 lol, no
Switches are ugly on the wall. Must be a better way than that ugly switch.
I’m a contractor in Florida and we do not need them by code here I’m guessing that is a code there if not then I don’t know what they were thinking!😂
Let me rephrase that code says you have to have a means of disconnect within 5 foot of the air handler but they’ve never made us do that here. I’ve installed 100 or more units and no inspector has ever called me out and none of the other contractors I know do it.
Manufacturer's instructions say not to splice the cables, yet you have switches on every indoor unit. Big no no. Local inspectors are dykks.
The switches were code for years here in NH. Luckily they changed it going forward so they are no longer required.
