The answer to 'how to clean heat pump' is to regularly clean the outdoor unit of your heat pump to maintain its efficiency and extend its lifespan. This involves clearing away any debris or vegetation around the unit, cleaning the coils, and checking the refrigerant levels.
Start by turning off power to the unit and using a garden hose to gently spray the coils, being careful not to bend the delicate fins. Use a soft brush to remove any built-up dirt or debris. You can also use a coil cleaner solution to help break down grime. Make sure to clean the air intake and exhaust vents as well. Finally, check the refrigerant levels and top up if necessary, following the manufacturer's instructions.
