Yeah yeah I know it's a bad idea but can it work? Mainly I would leave it off and it would get turned on for the summer and winter days where I have a specific project lined up. I'd run it like 10-20 days a year so the efficiency is not relevant, but my question is can a unit keep up and what is the rule of thumb re: BTU for an application like this?
Ok BUT why would you want to? BTUs are what they are and IME insulation and air sealing are most cost effective decisions before determining heat/cooling devices
Cos I'm either going to move in a couple years or tear down the garage and rebuild it. I can do the mini split install myself (I have hvac and electrical experience) and re-use it down the road also, so this is a cheap stopgap....if it would work.
The place I work does this. The only A/C we get is if you stand in from of the unit. Sucks.. Also have a swamp cooler to help. He’s talking about getting another unit with 3 more inside units so we have cool zones.
Ok makes sense a a stop gap measure… having never done it can’t help help with effectiveness cubic feet of area divided by r2 (insulation WAG) normal temp to desired temps BTUs needed for delta
Oh good point, the calculations would be pretty easy for this since you can assume basically no r value.
