One system that heats and cools. Repair, replacement and the twice-a-year service a heat pump needs because it never gets an off season.
A heat pump is the only piece of equipment in the house doing two jobs. In summer it moves heat out the way an air conditioner does; in winter it reverses and moves heat in rather than burning fuel to make it. That is why replacing one replaces two systems, and why servicing one is not the same as servicing a furnace.
Running in both seasons means a heat pump accumulates far more operating hours than equipment that sits idle half the year. Reversing valves, defrost cycles and refrigerant charge all need attention a cooling-only tune-up never touches. R. Davis Mechanical installs Lennox and Heil heat pumps and services all major brands.
Losing heating or cooling? Tell us which mode is failing when you call 412-370-0464 - that one detail narrows the diagnosis considerably.
build
Stuck in one mode, an outdoor unit iced over and staying that way, running on backup heat constantly, or no output at all. We test both modes to find the fault.
hvac
New and replacement heat pumps sized for both heating and cooling loads, with backup heat and changeover planned rather than left at the factory default.
event_repeat
Service in both spring and fall covering refrigerant charge, the reversing valve, defrost operation, coil condition and electrical connections.
A heat pump running on backup heat for weeks is the failure that costs the most and shows the least. If your winter electric bill jumped without a change in habits, have it checked.
We will lay out how each option performs in Pittsburgh's climate for your specific home, what it means for your existing ductwork, and what backup heat you would want alongside it.
