Even if you live in a more moderate climate and your heating system rarely has to work that hard, a breakdown can be a major inconvenience. Your ability to recognize problems early will help you avoid this situation and may allow minor issues to be repaired before they turn into big problems. Here’s a closer look at some issues that frequently lead to furnace breakdowns.

4 Problems That Could Cause Your Heating System to Fail

1. Clogged Vents & Ducts

As dust is pushed toward your vents, airflow becomes obstructed. Similarly, debris and rodent nests often create blockages in the ducts. As these problems diminish airflow, the home won’t be heated as efficiently, and your heating system will work harder to maintain the same temperature. Getting your ducts and vents professionally cleaned once a year eliminates these blockages, so you won’t waste energy and cause more damage to your system.

2. Dirty Filter

In addition to cleaning or replacing your air filter at the start of every season, be sure to check it routinely every month in case of excess buildup of dust and debris. When a dirty filter isn’t replaced, airflow is blocked, which forces the blower and combustion chamber to work harder. As a result, your home won’t be heated as efficiently and your system will break down that much sooner.

If you have long-haired pets or family members with allergies or respiratory problems, you’ll experience better indoor air quality if you replace your filter every six weeks. 

3. Malfunctioning Thermostat 

While a bad thermostat won’t cause an immediate breakdown, it can overwork your system and speed up the rate that the mechanical components become degraded. An HVAC contractor can test to see if a thermostat is faulty, but you can also pinpoint this as the source of the problem by observing changes in the system’s functioning.

For instance, if the system kicks off before heating the room to the accurate temperature, or if it cycles off and back on frequently, a bad thermostat may be to blame. Check the batteries first to rule out a simple issue. 

4. Faulty Ignition System

If your HVAC unit is operating but not producing heated air, the problem may be with your ignition system. For a gas-powered system, check the pilot light. If you relight it and it won’t stay on, there may be a problem with the gas flow.

In systems that rely on an electric ignition, a lack of heat can indicate a shorted-out wire. In either case, an HVAC professional can help you quickly pinpoint the problem.
