Hello, how is all? Ok here is the scoope,I live in a two story townhouse on he end. This is my first winter here and we have electric heat. In the summer are bill was around $98.00 with central air ,This winter are bill has gone up to $189.00 , now my question I have noticed that no matter where you have the temp set at, when it reaches the setting and shuts off, It is no longer then 20 minutes to it kicks back on. Is this natural or something wrong with my thermostat ? Can the difference between the cut off and cut on be changed ? Or is this something I want to mess with ?
