When your heating system is not behaving the way it should, it is easy to assume the worst. Yet oftentimes, the solution to your HVAC system woes is right in front of your face. Our emergency HVAC repair technicians respond to many calls in the winter. And many of them are due to the thermostat. Some of the problems are what we jokingly refer to as “operator error,” while others are from thermostats that have just reached the end of their useful life. Is your thermostat causing your heating problems? These scenarios could point to thermostat troubles.
If your system is not running or it is not warming your home as well as usual, the first thing to check is your thermostat settings. The on/off switch may have been bumped, or your children or significant other may have adjusted the settings on your home heating installation unit.
While frequently turning on and off – dubbed “short cycling” – is common in extremely cold weather as your system works to maintain temperature, a faulty thermostat could cause your HVAC unit to cycle on and off repeatedly. In this case, damaged wiring resulting in a poor connection may be the culprit.
If you’ve noticed your energy bills are higher than usual, your thermostat could be to blame. A thermostat that is not correctly reading the temperature could cause your home heating unit to overwork. The more it cycles on and off, the more energy your heater consumes. To head off high electric bills, schedule a seasonal maintenance check, including a thermostat evaluation from your local HVAC technician to identify issues before seasonal temperature extremes take a toll on your finances.
A fan setting in the “ON” position will cause your blower/fan to run constantly. If the blower/fan on your heating and cooling system will not turn off, check your thermostat settings and make sure the fan setting is set to “AUTO” so your fan will only run when your system is heating your home.
If your furnace is over or underheating your home despite thermostat settings, you could have a mismatched thermostat and furnace. These two devices must be properly paired. Having your local heating repair contractor verify your furnace is compatible with your millivolt, low voltage, or line voltage thermostat is an easy way to correct frustrating operational issues.
