When Los Feliz residents need heat pump repair, LC Heating & Air delivers same-day service backed by 20+ years of working in the LA market. Los Feliz is one of the most architecturally distinct neighborhoods in Los Angeles — home to a dense concentration of 1920s and 1930s Spanish Colonial Revival and Mediterranean-style homes, many with original plaster walls, tile roofs, and architectural features that make HVAC installation and ductwork routing genuinely challenging. LC Heating & Air has worked in Los Feliz homes for two decades and understands the unique requirements of older construction: how to run new ductwork without destroying original plasterwork, where to locate condensing units on tight hillside lots, and how to size systems correctly for older homes with different insulation and window characteristics than modern construction. That local knowledge means our technicians arrive knowing what equipment and access challenges to expect — cutting diagnostic time and getting repairs done faster.
### 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 Feliz 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.
Local HVAC Challenges
Los Feliz's older housing stock presents three consistent HVAC challenges: original ductwork that is undersized for modern comfort expectations, plaster-and-lath construction that complicates new duct runs, and hillside lots with limited space for outdoor condenser placement. We use flexible installation approaches including mini-split systems for rooms that cannot be served efficiently by a central duct system, and we always photograph and document duct routing before closing walls so homeowners have records of what is in their walls.
Neighborhood Context
Many Los Feliz homes have partially original duct systems — galvanized steel trunk lines from original installations combined with flex duct extensions added in various decades. This patchwork ductwork is a common source of efficiency problems, hot and cold spots, and duct leakage. We assess the full duct system during every installation project and recommend consolidation or replacement when the existing ductwork would significantly compromise new equipment performance.

What Los Feliz customers say about heat pump repair
Verified reviews from homeowners in Los Feliz and nearby neighborhoods who used our heat pump repair service.
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
“Got a 3-zone Daikin system for our craftsman home — bedrooms upstairs, living room downstairs. Each room has its own temperature control and the monthly electric bill is actually lower than our old window units combined.”
“LC installed a Daikin heat pump in our Atwater craftsman. They coordinated with the electrician for the panel upgrade, pulled permits, and handled the TECH Clean rebate. Total came in under $8,000 after incentives.”
