I am converting my garage into a family room. Trying to figure out whether I can tap into my existing central air or if I need to go with a ductless mini-split.
Did a HVAC-CALC tonight.
Existing: 10,000 Gain, 29,000 Loss
Garage: 6,500 Gain, 13,500 Loss
Total: 16,500 Gain, 42,500 Loss
I have a 1.5 ton 10 SEER A/C, and a 40,000 BTU furnace.
So I am close. But is it too close? Any advice?
