The Ultimate Ferrari Garage will now be COOL in the hot Texas summers. I added a Pioneer Diamante Series 24,000 BTU 18 SEER 230V Ductless Mini-Split Air Conditioner with Heat Pump which is a bit overkill for my garage, but I want to actually be able to cool it with 2 hot cars when it’s 108 out. The DIY installation is not that complicated, although if I was doing it over, I would have had a friend help just because things were heavy.
