I have an 1,800 sq ft garage. It is insulated (R-19 walls, R-50 ceiling R-13 garage doors) and has a heated floor. I'm considering adding a mini-split for more summer comfort but I'm not sure I can get on that is big enough.
The garage is "L" shaped, but I really only care about cooling the larger side of the garage. Most of the work I do is going to be under the fan area or at least in that larger garage area.
I've used calculators and seen anything from 18K BTU to 50KBTU. I'm assuming it's closer to the 50K BTU mark.
Are there mini-splits that are big enough for this area? Is there a mini-split that is 1 zone but has more than 1 "blower" unit? Or am I better off with a multi-zone system and just setting them to run at the same time?
Any recommendations are welcome.
Edit: I'm in central Iowa.
