Thermostat Not Accurate...

This is usually due to a thermostat that isn't properly calibrated. This can be a nuisance call because some thermostats, even after being calibrated, lose their calibration again shortly afterwards. Brand new thermostats out of the box can often do this.

What is the answer? Digital thermostats. They never lose calibration and they are extremely accurate. Older mercury-styled or bi-metal thermostats are quickly being phased out. New digital thermostats are also very sophisticated; with programmable features capable of saving customers up to 30% in utility costs.

There are a few other things that could cause this problem besides the thermostat though.

Below is a list of possible causes. Items in red usually require a service call. Items in blue however can be addressed, some even fixed by the homeowner.
