| I installed a heat pump in my garage earlier this summer. I'm kicking myself for not doing it years ago. 
17200 BTU of AC, and 21600 BTU of heating on those rare occasions I'll need it during our brutal Dallas winters.   it will maintain 65 degrees in the garage when it is 105 out, costs 8 cents an hour to operate. Whisper quiet too. I did most of the install and electrical myself, had to pay a licensed HVAC guy for check out and power up to validate the warranty. Any of you have this setup? It makes working on Z's a pure joy in the summer
