I am in Central Texas. We are just coming off of 45 days of 100+ temps.

My shop is 16 x 24 and I use a through the wall AC/heater unit to heat and cool the shop. The shop is traditional stick built and is insulated.


I am an week-end (at best) hobbyist. Right I turn on the Ac or heat before or as I going into the shop. It is not uncommon for the temps in the shop to get into the 90s if it has been some time since I have been in there.

I am wondering about leaving the AC on all the time. (I am also looking replacing the wall unit with a Mini Split Mr Slim DIY kit).

How many of you hobbyists out there keep your shops conditioned year round?
