You may not be thinking of your heat pump condenser coils as part of your spring cleaning tasks, but we recommend adding it to the list. If you have a central air conditioning system, you have two main parts, the indoor air handler (evaporator coils) and the outdoor heat pump (condenser coils).
The heat pump utilizes a fan to release heat absorbed by the refrigerant. When the fan is on, air flows into your coils/fins, pulling dirt and debris in as well. When grass clippings, “cotton,” dirt, leaves, and other debris gather on the coils, airflow and energy efficiency are significantly reduced.
