What do you guy's think? I have been doing a house addition for the last year or so, and with that I upgraded to a larger central A/C system, my old one was only approx 10 years old and worked very well.
So I was thinking about installing it and the old furnace into my garage at home, I have all the parts I would just have to have it recharged after the install.
I live in Michigan so the heat is not all that bad, but most of my garage time is after 7:00 at night so I would be doing it more for bug control than heat control.

What do you guy's think, should I do it or not?

Attached or detached garage? What type heat?

I have heat and AC in my 1000 ft detached. Love it. Free is a great price as well. Help your resell value to.

Check here under heating and ac for more garage info.

Attached, forced air, with natural gas.

I would if I had that..install it in the garage..and if you place it so it blows in you can have filtered air when you need it..Place a filter bank on the on the intake side..and filter outlets on the other end of your shop..

Just use the thinking cap and it will all work out..

I'd do it.

i would so do it !

as a car guy, im sure you spend enough time in the garage to get good use out of it. and it will definantly help on those muggy days

set up a filter system like previously mentioned and it will keep the garage fre of fumes from welding, grinding, painting, doing fuel related tasks ect

Check local codes. You may not be allowed to put duct work or any filtration in the garage.

I don't exactly know what you mean but there should be no return air going back into the furnace from a garage or kitchen.

One does not use return air ..one takes air from outside runs thru the air handler and then into the garage..totally different from a normal HVAC system..

is this system just for the garage? or does it supply the rest of the house as well?

This will be just for the garage. I already have a forced air furnace in the garage now so I will replace it with my old house furnace and A/C unit. I just installed a new Train furnace and A/C unit for the house. I have made my house just over double its original size so I had to install a new setup. I will run a fresh air make up to the furnace, for the proper fresh air.

I have a 1500 sq ft garage that is air conditioned with a large window unit at ceiling hight. . There are no ducts. No thermostat. Just a on/off switch.
A simple system and it works great.

As you know cold air drops so aim it toward the ceiling. With enough fan you will not need any duct work. You do not have to balance any rooms with air flow. you need a filter on the intake to keep the coil clean.

Just a suggestion.

Since the garage is attached to home did you use 5/8 fire rock seal all opening into the home from garage with fire caulk and put in a steel fire door that you will be using to enter the living space. Codes hear are stricked.

Mine is 440 sq.ft. detached and I've thought about doing similiar. But I've had a couple of questions about doing it that way.

1. Are most of the same size rated (say 20,000 BTU i.e.) the same size or close to it for future replacement purposes?

2. Do I need to do anything to minimize the chance of wall damage (extra bracing under it or for fire protection)?

3. You kinda answered part of it in yours, but do you leave it installled 365 or take it out? Have you got a cover over the exterior parts, do you tarp it in the winter?


Thanks, Chet.

Chet, My ceiling hight is 16 feet, This means to me the following:

It stays in 365.

I found it hard to adjust the thermostat. So a switch on/off works for me.

I never cover it.

I acid clean the coil every 3-3 years

To answer your questions The hole for the a/c is about4 inches larger. The trim is used to allow me the flexibility to install a replacement unit. The unit is supported by 2 angle iron brackets on the exterior.

The system was used when I bought it and I have been using is for the past 14 years. It never has been recharged. (Now it will blow up )
