I have a forced gas unit and it sometimes comes on twice. What I mean by that is it runs stops and kicks right back on again. I used to have a nest thermostat and was told get rid that one because not having common wire can cause that. I since put the original Honeywell thy came with house (only been here a year). I don’t know if this is normal when house is colder or is it a thermostat starting to fail and not catching right temp. Any ideas?
