How to Clean Heat Pump Coils

A heat pump can provide efficient heating for your home, especially if you live in a warmer climate. The pump delivers one-and-a-half to three times more heat energy than the amount of electrical energy it uses. The coil can become dirty, though. To keep the unit running as efficiently as possible, you need to clean it thoroughly from the inside and outside.

  1. Turn off power to the unit before cleaning.

  2. Check the indoor heat pump coils. Look for dirt and debris.

  3. Use a soft brush to clean the coils, brushing off any surface buildup.

  4. Mix a light detergent with water in a spray bottle. Spray the solution on the heat pump coils, coating the soiled surface.

  5. Rinse the heat pump coils thoroughly. Wet a cloth and work it between the coils.

  6. Replace the filter every 30 to 60 days to make sure the air is flowing freely through the unit.

Warning

  • Do not bend coil fins when cleaning them.
