What to Expect From a Heat Pump Tuneup in Fairfax

After the nasty winter we experienced this year in Northern Virginia, a heat pump tuneup is definitely in order. Schedule your tuneup early to make sure your heat pump is geared up to provide maximum cooling no matter what Mother Nature has in store this summer.

Heat Pump Tuneup

A heat pump is designed to provide efficient cooling and heating by leveraging the principles of refrigeration to transfer heat energy out of and into the home. Optimal refrigerant charge and free airflow across the heat-exchange coils are required for these functions. Following are the basic workings and tuneup procedure.

Refrigerant

Refrigerant is placed under pressure and temperature changes by the compressor, indoor heat-exchange coil (evaporator) and the outdoor heat-exchange coil (condenser). As cool, liquid refrigerant flows into the evaporator, it vaporizes under low pressure. This process draws heat energy from the airflow blowing across it. The loss of heat in the air is what creates cool air.

  • During the heat pump tuneup, your technician deep cleans the indoor and outdoor coils so that heat energy transfer is maximized.
  • The coils and refrigerant lines are checked for leaks, and refrigerant levels are checked.

Airflow

Free airflow is required across the evaporator and condenser coils, which in turn requires unrestricted airflow through the living spaces, air ducts and outside unit.

  • The air filter is checked for cleanliness and fit. A clogged air filter restricts airflow and makes the heat pump work harder.
  • The air ducts are visually inspected for obstructions, leaks and damage.
  • The outside unit is checked for obstructions, such as grass clippings, overgrown vegetation and debris.

Drainage

Clear drainage is important for optimal heat pump operation. You do not want standing water in the drain pan, or a clogged drain line that causes water overflow inside the home.

  • The drain pan is inspected for standing water and mold.
  • The drain line is flushed and chemically treated to prevent mold and bacterial growth.
  • Drainage at the outside unit is checked for clearance and free water flow.

These maintenance steps, and many more, are required for optimal cooling. To schedule a heat pump tuneup for your Fairfax area home, please contact us at HVAC Unlimited Heating & Air Conditioning.
