12 or spend the money for 18k btu for insulated garage? (Virginia)
I have an attached 2 car finished garage I’m planning on using for a gym/ gaming set up. normal ceiling height. I plan on keeping it around 75 when working out in the summer, and probably 65-67 in the winter when I’m working out. Should I spend the extra to get the 18k. Looking at about a 500-600$ difference and I’m not sure it’s worth it.
