Not All HVAC Maintenance Is the Same — It Depends on the Season

Did you know that preventative HVAC maintenance is recommended not once but twice a year? That’s because in different seasons, you use different equipment, of course. In fall, an HVAC tech will look mainly at the furnace or other heating equipment, while in the spring, the tech will inspect the air conditioner. However, a technician will also look at certain equipment in both seasons, such as the thermostat, the air handler, and the controls.

Let’s delve a little deeper into seasonal HVAC care and how it affects your household comfort and budget.

Cooling Season

As warm as it is in the Coastal Bend area, we are naturally most concerned with the air conditioner and how it performs during the long cooling season. That’s why we recommend a spring inspection before you turn the A/C on in earnest. (Maybe, as warm as it’s been in January, you’re already using it.)

An HVAC technician will perform these tasks:

  • Check refrigerant levels, adding some if need be. (If you’re using R-22, expect to pay a high price.) Check for leaks if refrigerant is low.
  • Inspect the evaporator coils, cleaning them if need be.
  • Inspect the condensate drain, flushing it with bleach.
  • Inspect the outdoor condenser coils, cleaning them if needed.
  • Check the compressor operation, including the condenser and compressor fan motors.

Heating Season

In the winter, these specific tasks should be performed on the heating system:

  • Check the burners and clean them if necessary.
  • Adjust and clean the pilot light assembly.
  • Check the heat exchanger for cracks, corrosion, and dirt.
  • Check the gas line, from the furnace valve to the burners.
  • Assess the gas pressure.
  • Inspect the flue pipe.


Whether it’s fall or spring, the HVAC tech will perform these tasks:

  • Check the operation and calibration of the thermostat.
  • Test the voltage and amperage draw of the blower motor.
  • Test the controls.
  • Change the air filter.
  • Inspect electrical connections.
  • Adjust the fan switches if necessary.

Having your HVAC system inspected regularly can lessen the chance of breakdowns, as well as inefficient operation. Replace parts as needed and your HVAC system will run better, with less wear and tear on parts.
