heating/cooling garage idea, need advice...

[Raze]

For you HVAC guys, my garage sits 'inside' my house (master sits over it), no windows or external doors except the garage doors themselves, and my house is brick. Therefore adding a proper separate unit inside the garage is going to be difficult and expensive since I'd have to either cut brick or route it through interior walls and floor through the basement. I had an idea though.

I have a vent that runs into my laundry room from my basement air handler which is on a shared wall with the garage. My thought was to add a vent into the garage from this vent (essentially pumping conditioned air into the house and garage from this one vent) when I'm out there working on my cars. The only major problem I see is that the garage wouldn't have an intake and thus could force that vent to have the wrong pressure relative to the house. Alternatively if I added the intake vent would that cause problems overrunning my unit since I'd be handling the outside air.

I'm looking for clever solutions if possible, thanks...

Do not use an interior HVAC system to condition a garage space. That's just asking for exhaust gasses to come into your house.

I went with a Mitsubishi mini-split heat pump unit. Just needs a small hole in the outside wall. It's also VERY efficient.

My best advice would be asking this question in the proper sub-forum where all the HVAC guru's hang out.

(No attitude intended - just trying to help a fellow GJ member out. Maybe a moderator will move it.)

I am also planning for a mini-split unit.
