What to expect from LC Heating & Air
### Heat Pump Repair Throughout Greater Los Angeles Heat pump systems combine the functions of an air conditioner and a furnace in one unit — which means heat pump failure affects both heating and cooling simultaneously. LC Heating & Air provides same-day heat pump diagnosis and repair throughout Los Angeles County for all major brands including Carrier, Lennox, Trane, Daikin, Mitsubishi, Rheem, and Goodman.
Overview
### How Heat Pump Failures Differ from Standard AC Heat pumps have most of the same components as standard air conditioners (compressor, condenser coil, evaporator coil, expansion device, capacitors, contactors) plus additional components that enable reversible operation: the reversing valve (which switches the system between heating and cooling mode) and the defrost control system. Heat pump failures that don't occur on standard AC systems include: reversing valve failures that cause the system to stay stuck in one mode, defrost board failures that cause ice buildup on the outdoor unit, and check valve failures that affect one operating mode but not the other.
### Reversing Valve Diagnosis The reversing valve is the component most unique to heat pump systems, and it's a common failure point. A stuck reversing valve causes the system to provide cooling when heating is called for, or vice versa — or to produce very little output in one mode while performing normally in the other. Reversing valve diagnosis requires measuring refrigerant pressures in both operating modes and comparing the results against expected values. We carry reversing valves for all major brands.
### Emergency Heat Mode If your heat pump is not providing heat, you may have an "emergency heat" or "auxiliary heat" setting on your thermostat. Switching to this mode activates a backup resistance heat strip, bypassing the heat pump. This provides temporary heat while we arrange a service call — though it uses more electricity than the heat pump mode.

What customers say about heat pump repair
Verified reviews from Los Angeles homeowners who used our heat pump repair service.
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
“Switched from gas furnace to a heat pump after talking to LC. They handled the TECH Clean California paperwork and we got a $2,500 rebate plus the federal tax credit. Total out of pocket was about $5,500 for a system that now heats and cools. Gas bill went to zero.”
