Perform These HVAC Tests Routinely to Maintain Your System

With the hot temperatures in the Yuma region, most homeowners are concerned that their air conditioners will keep running throughout the long cooling season. That’s not to say that we also don’t sometimes need our furnaces during the occasional cold snap. Either way, homeowners in the know want to do all they can to ensure their HVAC systems keep going without a hitch all year.

To do that, your HVAC consultant recommends that you have regular maintenance twice a year: in the spring for the air conditioner and in the fall for the heating system — even though our winter temperatures rarely fall below 47 degrees. Even so, houses can seem chilly when the temperatures dips, so you want your heating to work well when you need it. When you schedule your maintenance, be aware that your HVAC tech will be performing an HVAC test or two to make sure your equipment is running right.

What are these HVAC tests? Let’s take a look at a few of them.

Tests That Your HVAC Tech Will Perform

Your HVAC tech will perform the following tests on your air conditioner:

  • Check refrigerant levels.
  • Inspect electrical wiring, replacing worn wires.
  • Clean the evaporator and condenser coils.
  • Check the condensate drain for leaks or blockage.

The tech will also test the airflow of the AC.

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

  • Check vents for blockage.
  • Check burners to ensure they’re burning blue instead of yellow and that burners are clean.
  • Look for cracks in the heat exchanger.
  • Check and clean the blower.
  • Examine the flue.

HVAC tests that may be performed for the furnace include:

  • Ensure that the blower access door has a tight seal.
  • Perform an amp-draw test on the blower motor.
  • Check the burner to ensure proper ignition and test the flame sensor for accurate operation.
  • Test calibration of the thermostat. (This should also be tested during your spring inspection.)
  • Test the unit’s safety controls, including the high-limit control, to prevent overheating of the furnace.
