Modern heating systems are normally reliable, year after year, provided they receive a professional installation by licensed HVAC technicians and continue to have annual maintenance. But no system can ever be 100% reliable, and no amount of care can protect a heater from all malfunctions. At some point in your current heater’s service life, you may need to call for heating repair in Fresno, CA from our trained team.
One of the more common problems that affect forced-air systems (which include all types of furnace and heat pumps) is trouble with the air filter. This isn’t a filter for providing better indoor air quality, but the standard filter attached to the HVAC cabinet that stops dust and dirt from getting into the heater through the return air vents. An air filter clogs over time and must be replaced every 1 to 3 months so air can flow freely through the blower and heater.
