HeatingTips and AdviceSimple repairs for your heating system

January 3, 2023by Dev

At times the problem is as simple as changing batteries in your thermostat. Other times it can be a critical part that is essential to maintain the operation of your central air and heating system simply wore out at the wrong time. Finally, maybe yearly maintenance on your heater was overlooked.

If you are worried that your heating system will break down during the winter months, we recommend taking annual maintenance to minimize the problems caused by the most common causes of unexpected heater breakdowns.

Check your thermostat

A faulty thermostat could be to blame if your heater fails to generate heat. Check whether your thermostat has fresh batteries and is set on heat or auto. If it is set on cool, the thermostat will not call for heat. Sometimes a programmable thermostat can get disrupted due to a power outage.

Inspect your vents for clogs

Any indoor blockage can interrupt air circulation and overheat your heater, which may cause it to shut down. You should make sure to check for obvious signs that return air intakes are free from obstructions like furniture and drapes. You may be surprised how often this can be overlooked.

Many central air-conditioning and heating systems include air filters located in the return air vents. However, sometimes filters are located in furnaces themselves. If that’s the case, make sure your air filter is clean and that a blockage or dirty filter is not the cause of the outage.

More serious problems

Newer heating systems have ignition systems that only ignite the burner for heat when the system requires it. If you hear a lot of noises when your heating system tries to heat your home, this may indicate a problem with the igniter. This is something you would want to have a local professional, like those at Mountain Valley Home Comfort to come and inspect.
