Top 5 Reasons Your Furnace Might Fail

Furnaces don’t break down all the time, but failure tends to happen at the most inconvenient time and you have to call for emergency furnace repair in Lose Gatos, CA. There are so many parts and systems that make the furnace work and any number of things can go wrong. That said, here are five of the leading causes of furnace failure:

1. Broken Thermostat

Over time a thermostat can break or become decalibrated. And without the thermostat working the furnace will not trigger properly. It might trigger too often or not trigger at all. So if your furnace isn’t working a good place to start is with the thermostat. Make sure it is set to the proper temperature and mode. Maybe the furnace isn’t working because someone simply adjusted the settings without your knowing. But if the settings seem correct and the furnace still isn’t running the thermostat may be malfunctioning and you will need to call for furnace repair.

2. Clogged Filters

The filters in your HVAC system are meant to keep dirt and debris from circulating in your home. But they also keep dirt and debris away from the furnace so it can work properly. If a filter gets too dirty it prevents the free-flow of air. This can cause the system to run inefficiently and wear out faster than usual. To prevent these issues you need to check your filters each month, especially during peak use. And when it starts to get clogged you want to replace it right away.

3. Ignition Failure

If your furnace is kicking on, but warm air is not coming through the vents it might be because of a pilot light or ignition failure. If this fails the furnace cannot ignite the burners or produce heat. You want to check the pilot light or ignition regularly, at least once a year. And if the pilot light is not operational, you can try to ignite it by following directions on the front of the furnace. If that doesn’t work you will want to have your furnace checked out.

4. Blower Motor Failure

Another common problem is a furnace that doesn’t distribute warm air around your home. Maybe the ignition or pilot light engages properly, but the blower doesn’t activate. If this happens you should inspect the fan motor, bearings, and belts. If any of these show signs of wear you should get them replaced.

5. Poor Maintenance

You shouldn’t expect your car to run without routine maintenance and the same should go for your furnace and HVAC system. Annual service checks and maintenance will prolong the life of your system and prevent unexpected failure. So don’t put it off.
