My Thermostat Doesn’t Maintain Temperature

This is usually caused by a thermostat that isn't properly calibrated. This can be a nuisance call because older thermostats are mercury styled and after being calibrated can shortly lose their calibration.

One solution is the new digital thermostats. They never lose calibration and most have additional programmable features that can save customers 20-30% in fuel costs.

However, there are other things that can cause this problem besides the thermostat. Below is a list of possible causes and things to check. Items in blue can be addressed or fixed by the homeowner. Those in red usually require a service call.

  • Direct sun or another heat source hitting thermostat
  • Thermostat not level

  • Draft through hole in wall behind

Hope this has been of some assistance, however they are just rough guidelines and not all possible conditions are covered.
