What HVAC Tests Can You Perform to Maintain Your System?

November 18, 2021

Preventative maintenance on your HVAC system can ensure that it runs properly during the times when you need it most: during the worst storms of winter and the hottest summer months. With up-to-date maintenance, you're less likely to have breakdowns. Furthermore, your equipment will run more efficiently, lowering your utility bill during the height of heating and cooling seasons.

HVAC experts recommend that homeowners have preventative maintenance performed on their systems twice a year, in fall and spring, for the heating system and the air conditioner respectively. Part of that maintenance will include the performance of an HVAC test or two to ensure that your system is running at its peak.

Here are a few of the HVAC tests that might be performed:

Routine HVAC Tests and Maintenance Tasks

For a furnace inspection, the tech will do the following:

  • Check burners to make sure they are clean.
  • Check the burner flame to ensure it's blue instead of yellow.
  • Inspect the heat exchanger for corrosion and cracks.
  • Inspect vents.
  • Check gas connections.
  • Check and clean the blower.
  • Examine the flue.

Some typical furnace tests:

  • Make sure the blower access door has a tight seal.
  • Perform an amp-draw test on the blower motor.
  • Ensure proper ignition of the burners.
  • Test the flame sensor for correct operation.
  • Test the thermostat's calibration.
  • Examine safety controls. Test the high-limit control to prevent the furnace from overheating.

Tests that should be performed on the air conditioner:

  • Refrigerant levels should be checked.
  • The system should be checked for electrical leaks.
  • Electrical wiring should be inspected for loose or worn wires.
  • Airflow should be measured through the evaporator coil.
  • Verify electric control sequence and make sure heating and AC can't operate together.
  • Condenser and evaporator coils should be cleaned.
  • The condensate drain should be checked for leaks, blockage, corrosion, or other problems.
  • Perform an amp-draw test on the blower motor.
  • Test the AC's airflow.
  • Check the thermostat's accuracy.
  • Check ducts for leakage. Have them sealed if they have cracks or are disconnected.
