      You should know before you buy that this unit will not hold your temp at the setting. It will instead run up to 4 deg below your cool temp or 2 deg above that temp. I have this set on 68 and it will not stop running and cools until it reaches 64deg. If you want precision this is not your unit. If you want the most budget, DIY option, this is what you want but done expect it to run like any other HVAC u it you have ever used before.
