Mr. Cool - has anyone tried these mini-split ac?

Thanks- any other reasonable options to help cool off upstairs bonus room above a garage? I plan to insulate a little better, but it stays 5-7 degrees warmer than the rest of the house. Whole house is run on a 6 ton unit. So I was thinking the mini split would help for that one room. The quote to install a mini split from a professional was $7K.

well, im against both. Mini split arent bad, but they are way overcomplicated, as anything "high efficiency" is. The boards go out on them regularly. Those are a few hundred dollars. Everything is expensive and most of it takes forever to get. If an evaporator coil goes out, you almost have to replace the entire wall mount, due to how it's built. Cost in the neighborhood of 2-3k depending on BTU size.

i'd be curious to know what type of unit you have as they don't make 6 ton residential splits, or even really commercial 6 ton splits. Trane has a 6 ton package unit and York made a 6 ton commercial split back in the day.

is your model number "060" if so that is a 5 ton.

I have a Pioneer in my garage and it works great. The install was around $500.

I had done all of the mounting, hole in the wall, pad for the outside unit...etc. My AC guy just had to come pull a vacuum and check for leaks etc.

Mini splits are extremely common in Asia and Europe, they just are not common here. A lot of HVAC companies won't work on them, there's just not enough work I guess? Anyway, they are very efficient and great for cooling 1-2 rooms.

I've got quotes a couple times and they were absurdly high, labor in the $2000-3000 range for a unit that's under $1500 and I know there's no way its taking a team of 2 HVAC techs more than a couple of hours to install. So that seems normal OP because its hard to find someone wanting to do the work IMO.

I have one I bought from Lowe’s. Yeah I’m not happy.

First and foremost, reguardless of what pRt of the install you do, you will need to pay an ac tech to come out and pull a vacuum on the line. I had paid 200 bucks for someone to do this as well as cut and re- Ferrell the copper lines as they give you like 10 feet. The instal wasn’t bad as it’s two pieces amd 3 wire hook up. What they failed to mention is the size hole they tell you to drill is the exzact size of the wire and tubing that has to pass through.

As far as the unit, it started freezing up when running at 70 degrees during the summer. Installed in feb. worked well until June and then it would freeze and is Dropping water all over the wall. Heater doesn’t work at all either and pretty much is pissing in the wind. I suspect it’s low on Freon but don’t know.

Called Lowe’s as it had the warranty, Lowe’s just said they will send me my money back as they don’t have anyone to work on it. So I got it for free plus the Ac tech time. I’m going to have someone come out to check the levels but idk. I bought a portable stand alone unit that has no condensate run off and cut a vent through the wall to exhaust it. It works like a champ and was 300 bucks.

It’s an 18k btu and the area is about 400 sq feet. I’m like the mini split concept and know someone with an LG that’s bullet proof so I’m not going to knock the split concept. But I would buy a name brand from a local instal company or a brand that the big box stores carry and pay them to install.

Lol. Because I’m not an ac guy and had no clue what it was or how to do it lol. If I remember correctly it was to remove any air from the lines but I honestly don’t know.

Ahhhh. Ok. I did have the lines cut and re capped to remove the access. The manual however did state that you had to pull a vacuum. But I’m not sure why it shite the bed. I need to have the Freon checked as it may be my problem.

What would y’all recommend to cool a 400sq for pool house? Has living/kitchen area, small bathroom and bedroom.
