I am currently renting a house. It is about 1,500 sq ft and two floors. It currently has a regular non-programmable thermostat. I would like to install a programmable one but I am not sure if the current setup in the house will support one. Or am I wrong in thinking that programmable thermostats can only be installed in certain setups? Also, is it as simple as it looks to install one? Removing current and installing new one? I consider myself pretty handy, would it be something I can do on my own? Also, should I first confirm with the landlord that I can in fact install one or it should matter as it’ll be sort of an upgrade to their house?
