Furnace Repair & Maintenance Fullerton CA | OC’s Leading HVAC Company

Do I need furnace repair?

Traditionally when we get into the later months of the year (October, November, December), the need for heating comes up in many households. There are multiple scenarios where your furnace could be underperforming or in need of maintenance that could lead to higher long term costs or even hazardous environments. This begs the question “How do I know I need furnace repair?” We’ve developed a furnace inspection checklist that we think will help you have an idea of whether your unit needs service or not.

  • Age: If your unit has a long shelf life (10+ years) and hasn’t received routine maintenance (we recommend it yearly), it is most likely time to get that unit checked.
  • Check the air filter: An air filter replacement is one of the most common fixes that leads to inefficient furnace usage or poor heating. They are recommended to be replaced every 3 months.
  • Clean the burners: Making sure the burners and flame sensor are cleaned is very important. The flame should be a consistent blue, a yellow or flickering flame could indicate bigger issues such as a dirty burner or a bad mixture of chemicals in the air.
  • Inspect heat exchanger & CO detector: Making sure the batteries are replaced on the CO detector. Checking the heat exchanger for cracks & leaks is important as it transfers the heat from the combustion chamber to the air ducts. 
  • Check wiring, look for leaks, lubricate components: This is more of the general maintenance work you can complete on your unit. Since dealing with heat, these all greatly improve the efficiency of your heating in your home.
