How Yard Work is Affecting Your HVAC System

How Yard Work is Affecting Your HVAC SystemRegular yard work during the summer season is also a good opportunity to check and maintain the condition of the outside half of your central air conditioner. The outdoor unit comprises the condenser coil and fan that dissipate heat extracted from inside your house as well as the compressor, the vital component that circulates and pressurizes refrigerant. What happens out in the yard can affect the performance and energy efficiency of the entire cooling system, so taking care to protect and inspect the outdoor unit during yard work is a worthwhile effort.

When working in the yard, you should:

  • Protect the unit. While you’re cutting grass, raking leaves and trimming trees, make sure the air conditioner is turned off at the the thermostat and cover the unit with a tarp or other heavy covering. This protects the condenser coil from dust and dirt stirred up by mowing and raking, as well as grass clippings and leaves. It also keeps tree branches and twigs from entering the top fan grille and obstructing the fan mechanism.
  • Cut back vegetation. If grass or weeds have grown up around the unit, cut this vegetation down to make a two-foot open space on all sides of the unit in order to allow full air circulation in and out of the vents.
  • Inspect the unit. After you’re done with yard work, uncover the air conditioner and perform a visual inspection. Look for dirt and dust on the coil component and leaves or other debris inside the cabinet. Also look down through the top fan grille for leaves, twigs or other objects. If the coil surfaces appear dirty, turn off all power to the unit at the main electrical switch and hose down the inside of the unit with a garden hose fitted with a nozzle. Allow it to dry completely before restoring power.
