  • Garage Heating and A/C

    my 3 car garage is located in the house with the master bedroom above it. the ambient temps do fluctuate ( but not crazy like a detached) way more than the rest of the house as the garage has no ducts from the HVAC system. i have been considering installing a mini split system for a/c & heat. so my question is has anyone installed one? anything to look out for? are most brands equal? any info would be appreciated. they seem pretty easy to do as they are all self contained. i think the lines even come pre charged with freon.

    Hey Mitch, I had one installed a couple of years ago and think it's great. My building is a forme r carriage house not connected to the house. The foot print is similar to a three car garage but it only has two bays and a stair case in the center. The system is very quiet and heats and cools the space well You control it with a remote and it makes hardly any noise (either in the garage and outside). I had it hung from the side of the building so it is up off the ground. I'll check the brand and size and post the info probably tomorrow. You may be able to see the building in my avatar. I seem to recall it cost around $5,000. It would work even better if I addressed the air leaks around the old wooden doors.

      that would be great if you could check the size.. whats your approx square footage and ceiling height? is the air register assy mounted towards the ceiling?
      i know the outside condensing unit should be mounted high enough so the snow doesn't bury it. who did it for you?
      thanks for the reply

        My "two-car" garage is attached to my house, and has no direct heat from the house. It has it's own heater -- just blows hot air into the open space. I try to keep it around 50 degrees so that it's not too uncomfortable to be out there for extended periods of time.

            12,000 btu's is a ton of refrigeration. Or what it takes to melt a ton of ice over 24 hrs. So he has a 2 ton unit. My buddy likes mitzabishi (sp) he's done several garages for club members. He did one in eastern wash for a members rental house for a roadster body.

              by Jim Baskin III
              The old coal stoker finally gave out. Decided to buy another QuadraFire wood pellet stove. I have one in our family room downstairs in the house and has worked perfectly for 4yrs now. Nice warm garage for Bella PIA -30 Tudor and Mr.Peabody-30 pickup

              Could not be happier....

              “A” Pole Barn Wish List
              by Paul
              Indiana weather has been so cold this winter. I told the wife, “It's time to find a warmer climate, with no salt.” She said, “We don't need to move, you just need a heated pole barn.” She knows me well!

              With that said, to pass the time till spring, I thought I would make a wish list of the things I would want in a barn.

              Tool migration
              by Art Ebeling
              I spent this morning taking tools from my house garage to the polebarn. The house garage is heated so my Model A project spends it's winters there. My wife likes her TBird in the house garage so it is close and easy to use in the summer so the Model a goes back to the pole barn. Over the past couple of years I find that by the beginning of summer I have no flat bladed screw drivers in the pole barn...

              A Doghouse to Store Model A Engines
              by Tom Wesenberg
              I just finished this today. My garage is small and full, and I needed someplace to store my Delco Light Plant and a Model A engine. If I remove the Delco, I think it has enough room for 3 Model A engines. Storing parts under those cheap plastic sheets just doesn't cut it. This is so tight it's even mouse proof, but I may put some mothballs in to keep insects out.

              I don't think any community...

              Garage question
              by Mickey
              I have a large air tank in my garage and noticed water dripping around the bottom (condensation ). When I took a closer look I noticed a sticker that said to drain it daily. I didn't know that. After all real men don' t read the instructions. Realistically how often should one be drained. Letting all the air out and draining water after every days use seems a bit overkill. I realize that you...
