We have a very old thermostat, I just checked HD because their e-ad had them "on sale"..how would I ever begin to know what to get? There must be 40 to select from. We have an old round one, which I think is very touchy because it goes and goes then stops and shortly kicks in again. And setting a degree is like the lotto.
We have an old dbl wide mobile home elec furnace with central Air. Also are they hard to install or do we need someone to install it?
