How to Clean Heat Pump Coils

Heat pumps provide energy efficient heating and cooling for homes throughout the Delaware Valley and at the Jersey Shore. Dirty coils inhibit heat transfer so homeowners need to make sure their coils are clean to ensure the system remains efficient. Learning how to clean heat pump coils will help guarantee your system is running as efficiently as possible so your family remains comfortable all year long.

Many homeowners have professional HVAC technicians, like those at Oliver Heating & Cooling, clean the heat pump coils during a tune-up. The Oliver Peace of Mind Membership helps people stay on track with heat pump maintenance. We inspect all moving parts, clean the outdoor heat pump coils, and nip problems in the bud. We will provide options for additional cleaning if required. Regular maintenance protects equipment from failure and promotes energy efficiency.

Your outdoor unit may need more than biannual cleaning to operate effectively. A dusty environment, lawn clippings, pine needles, or an overgrowth of shrubbery all call for continual cleaning. You can stay on top of the problem by learning how to clean heat pump coils yourself. Keep in mind it’s always a good idea to have your HVAC system tuned up annually to ensure it doesn’t break down when you need it most. For more information about the Oliver Comfort & Safety Club or to schedule your heat pump tune-up, give us a call at 1-888-810-2681 or contact us online.

How to Clean Heat Pump CoilsTools You’ll Need

  • Rake or pruners
  • Screwdrivers or wrenches
  • Spray bottle
  • Hose with spray nozzle
  • Fin comb
  • Vacuum with soft-bristle hose attachment

How to Clean Heat Pump Coils Directions

  1. Turn off power to the exterior unit. You should see a shutoff box on your home’s wall by the unit.
  2. In the absence of an exterior shutoff box, disconnect power to the heat pump at your circuit breaker box.
  3. Confirm that heat pump is deactivated by trying to turn it on. If the power is off, proceed with the rest of the steps to  clean heat pump coils.
  4. Clear a 3 foot perimeter around your outdoor unit so plants and debris do not interfere with the air intake.
    • Rake away leaves and grass clippings.
    • Cut back bushes that grew too close to the unit.
  5. Take off the condenser unit’s outer case. You may need screwdrivers or wrenches to loosen screws or bolts.
  6. Remove the top grille and gently move aside the fan without disturbing any wiring.
  7. Vacuum the exposed fins with a soft bristle attachment.
  8. Fill a spray bottle with soap and water or a commercial coil cleaner.
  9. Spray cleaner onto the coils.
  10. Take care not to bend any fins while you work.
  11. To rinse, aim water spray directly at the fins to prevent them from bending.
  12. After rinsing the soap and dirt off, inspect fins to see if any are bent.
  13. If you see bent fins, carefully straighten them with a fin comb.
  14. You may now reattach the grill and outer case.
  15. Reconnect the electricity and test the unit.
  16. Indoor unit coil should be inspected and cleaned in a similar fashion if required. The system filter if properly maintained will help to keep the indoor coil clean.
