Window/through the wall heatpump

[rixtrix1]

Has anyone tried a "window/through the wall' A/C heatpump? I would like a unit for my 18x19 garage to make it workable year round( Phoenix area). Local online dealer has 12K units for $365 in Frigidaire and LG, but only offers a 90 day warranty. Garage has no windows, 16x7 metal door with 2" foam added, walls are R13 and ceiling is R36. Would only be using it on weekends during the summer months and sparingly evenings and weekends to take the chill off in Nov thru Feb during the few times the temps drop into the low 30's here in winter. Got a car project I need to get working on, but can't stand the heat/cold 7 days a week( Fleet mechanic).

What do you think, any good?

Replied to your other question - Also in Arizona

I had one in the house. Mine was ducted, but the one you are looking at might be 'hotel" format. When I built on I was able to get a surplus unit dirt cheap (like $365). Unfortunately the drip pan rusted out and I was forced to retire it. Would I do it in the garage? Sure. I would think 1 ton is plenty for your garage.

Thanks, shade. Nice to see the 1 year warranty!

firebirdparts,thanks, Tthe ones I've seen are just like a window unit, which I need to get it off the valuable, limited floor space and mount high on the wall.

I have space in my garage subpanel to add either a 120 or 240 volt circuit. I'm thinking 240V due to the lower amp, and $$$ draw. Just unsure of the durability as they're not too popular.

Echo what was in the other thread - buy something you like, then stick it in the wall. Doesn't have to be a true "through the wall" - it's just a little easier and the larger units usually have slide out internals.

When you don't want to lose a window, make a hole.

Falcon67, is your unit a heat pump? (Never mind, I just read your build thread. Awesome job, especially doing mos t of the work yourself!)I'll be mounting mine the same way as I have no windows.
Thanks!

Twenty something years ago I had one similar to Falcon's. Dedicated an opening on a back wall of the shop for it. It was inexpensive, good heat & cooling, & NOISY! Of course back then there weren't any mini-splits & I didn't have any good choice for quiet so I loved being able to control the temp in my shop. Today, I have a mini-split. You couldn't force me to go back to a wall unit. It'll work, but there are better choices...........

The link is to a window unit from LG --- make sure that the unit does not have any side vents. Nothing can be obstructed with a window unit.

The LG unit throws air a good 20' and is very quiet. Same with the Samsung in the other area. The tower fan makes more noise than the LG.

Yes, if looking to do that you look at the case vent locations to make sure they all end up outside.

The LG unit I mention has vents on the side and of course hot air is pushed out the back.
The vents are pretty far to the rear of the unit so most walls should accomodate no problem, unless its a weird wall thickness

Thanks. Normal 2x4 wall with drywall and T111 on inside and out, so most any unit should work.

The good thing about LG is they dont change their dimensions very often.
So I have had a couple units fail over the last 10 years (since doing AC in the garage)
All I have had to do is pull the guts out and slam in the new guts. The shell has stayed in.
