An annual gas furnace maintenance call would normally include:

As your furnace or ductless mini split system ages, general wear and tear can cause it to stop working efficiently. And in more extreme cases, older heating systems can suddenly stop working entirely.


  • Upon arrival at your home, we will carefully inspect your gas furnace and note its condition
  • We will change your replaceable furnace filter, along with inspecting your electronic air cleaner and other IAQ systems and cleaning the airstream components as needed. We will also clean the furnace blower and control compartment.
  • We will lubricate any moving parts that require lubrication to prevent noise.
  • We will inspect the pilot light assembly or ignition system and keep it as clean as possible
  • Make sure there is proper gas pressure and inspect the burners. If needed, clean the burners.
  • We'll clean and inspect the air blower as needed. We'll test the amperage and voltage for the fan motor to ensure it is in good condition.
  • Inspect gas furnace heat exchanger for signs of wear and tear. Clean if needed.
  • Inspect the flues and ventilation system to ensure a proper operation. If you have a condensing furnace, we will check the condensation drains and any condensation pumps.
  • Examine the ductwork for loose joints or hangers, and seal with mastic duct sealant if needed.
  • We will check your thermostats for proper operation. If they utilize batteries as a power source, we will change the batteries.
  • We’ll test run your gas furnace for several minutes. We’ll check for proper temperature rise, blower operation, and burner operation.
  • We’ll gather our tools, remove any old filters, and clean up any messes we’ve made.
  • We will clearly explain our services and any troubleshooting issues or recommendations for you.
