A home heating system that no longer keeps you and your family warm and cozy when it is cold ruins your home's indoor comfort. Knowing what the top causes of heating failure are and taking steps to prevent any problems that may develop is crucial to maximizing the performance and lifespan of your home heating system. 

If your heating system is giving out, here are some typical culprits behind the problem.

Dirty Air Filters

Your home's HVAC system has air filters whose job is to maintain both your heating system and your home's indoor air quality. These air filters work by removing dust, pet fur and dander, pollen, and other airborne contaminants from the air circulating within your home.

Over time, the filters become clogged with dirt, and this will inhibit the proper flow of air into your heating system. This will cause your heating system to run extra hard to warm up your space to the desired temperature. The strain on your heating system can cause it to break down, leaving you at the mercy of winter's biting cold.

Regularly cleaning or replacing dirty air filters will keep your heating system running smoothly and at peak efficiency.

Malfunctioning Thermostat

Is your thermostat on? Is it on the correct temperature setting? The easiest thing to check when your heating system isn't working properly is the thermostat. Your indoor temperature may not be warm enough because the thermostat is either turned off or is not set to reach the temperature you desire.

If your thermostat is turned on and set to the right temperature and yet your heater is blowing cold, you may have a broken thermostat.

Fuel Supply Issues

All types of heating systems require a fuel source to operate. If your heating system has no fuel or a problem exists in its fuel delivery system, then you won't receive heated air in your home. 

The most common fuel supply issues that affect electric heating systems include power blackouts, faulty wiring, and tripped circuit breakers. Gas supply disconnections and leaks are the most likely power supply issues that may cause your heater to stop working.

There are numerous reasons why your home heating system may act up. While you can fix some issues yourself, others require the skills and know-how of an HVAC contractor to be fixed correctly. If you need further assistance, feel free to contact an expert for help.
