What can be hiding inside a heat pump?
The first photo shows what we found inside the indoor unit during a recent service. The second shows what came out during cleaning. The third is the finished result.
This was inside a heat pump in our customer’s living room.
The part most people don’t realize is that this buildup is hidden inside the unit. If it’s sitting inside the heat pump, that’s the air your family is breathing every day.
A quick wipe of the filters won’t remove what builds up deep inside the system. We use a pressure washer designed specifically for heat pump coils to thoroughly clean the indoor unit and restore proper airflow.
