5 Common Reasons for Furnace Repair in Mount Vernon, WA

Now that fall is here and winter is approaching, it’s time to get ready for the heating season. Part of preparedness is knowing how to deal with problems as they arise. Although numerous things may go wrong with a home’s heating system, some problems are more common than others. In this guide, readers will learn the main reasons for Furnace Repair in Mount Vernon WA.

Clogged Air Filters

Dirty and clogged air filters are one of the biggest causes of HVAC breakdowns. When the air filter is clogged, airflow is diminished and the unit has to work harder to heat the home. Not only does this increase a system’s energy usage and make the home uncomfortable, it also increases the chances of failure. To avoid problems, check the filter once a month and change it when necessary.

Ignition or Pilot Light Problems

If the unit won’t turn on at all, it may be due to an issue with the electronic ignition or pilot light. On older systems, check to see if the pilot light is still lit and relight it if needed. If the system is a newer one with an electronic ignition and the burners aren’t lighting, call for an inspection and diagnosis.

Thermostat Failure

The thermostat tells the unit when to switch on and off. Even if the rest of the system is working as it should, a failed thermostat will cause temperature fluctuations. Avoid trouble by replacing the batteries in the thermostat at the beginning of the heating season, but if that doesn’t work, call today for Furnace Repair in Mount Vernon WA.

Heat Exchanger Damage

Over time, a furnace’s heat exchanger may become cracked. This problem is one of the most dangerous on the list because cracks allow lethal carbon monoxide to get into the air inside the home. During a pre-season tune-up, the technician will look for cracks and recommend system repair or replacement options if needed.

Prevent Issues With a Yearly Tune-Up

Homeowners will dramatically reduce the chances of furnace failure by scheduling a fall tune-up. During the service appointment, the technician will inspect the system for these issues and perform maintenance that prevents other problems from occurring.
