Heating Repair near Elmdale Ave. I received a call from a homeowner who reported that their heat pump was not working at all. After inspecting the unit, I found that the outdoor unit was clogged with debris and needed to be cleaned. I also checked the refrigerant levels and found that they were low, so I recharged the system. After cleaning the outdoor unit and recharging the refrigerant, I tested the system to ensure it was working properly. The homeowner was satisfied with my work and grateful to have their heat back.
