PCSA 2022 Heating Check Up Free w/ Install. Heat pump is heating very efficiently, auxiliary heat kicks on when needed, and filters changed. Both 5 inch filters were being used, one was in the return in the hallway and the other in the filter cabinet. Both were clogged and causing restriction, I removed the one in the hallway because it was pulled in the duck work and changed the one in the cabinet. The return in the hallway will remain open without a filter. Added some foam tape on wires pressing against outdoor system’s door to prevent any rub through.
