Evaporator coils are the components of a heat pump that absorb heat and move it through the system. Keeping your evaporator coils clean is pretty important to a heat pump's effectiveness.
When dirt and dust settle on the evaporator coils, it blocks airflow, which can cause your heat pump to work harder than necessary resulting in higher energy bills and eventually reducing its lifespan.
Additionally, blocked airflow can cause lasting damage to the compressor - a component essential in allowing refrigerant to condense and move between coils. Cleaning the evaporator coils as part of your professional heat pump maintenance will help keep your system running smoothly and efficiently.
