Top-rated independent heating and cooling across Orange County and Southern California
Heat Pump Not Heating
We repair heat pumps that run but blow cool or lukewarm air in heating mode, for homeowners across Arizona, California and Nevada. If your system is on, the outdoor unit is turning, and the house keeps dropping, that is a real fault and not just cold weather. Before you call, check that the thermostat is set to heat and not emergency heat only, confirm the breaker is on, and change a loaded filter. Then reach out and we will get a technician scheduled in your area.

What the job involves
A heat pump moves heat instead of making it, so when it stops heating the cause is usually in the reversing valve, the refrigerant charge, the defrost cycle, or the thermostat wiring telling it what mode to run. We start by watching the system through a full call: outdoor fan, compressor, indoor blower, and the air temperature at the supply register compared to the return. That tells us whether the equipment is failing or whether the house is fighting undersized returns and leaky duct runs.
What we check
We check the reversing valve and its solenoid, since a stuck valve leaves the system in cooling while the thermostat calls for heat. We read refrigerant pressures and superheat, inspect the defrost board and sensor, and verify the outdoor coil is not iced over or packed with leaf litter and dust. Auxiliary heat strips get tested too, because many homes lean on them harder than they should. Indoors we look at the blower wheel, the filter, and static pressure across the coil.
How we decide it is the right call
We decide by evidence, not guesswork. If the reversing valve shifts correctly and pressures land where they belong, the problem is airflow or controls and we say so rather than adding refrigerant. If the compressor is drawing hard and the coil cannot hold charge, we walk you through repair versus replacement with the age and condition of the equipment on the table. Marine mornings and hot afternoons swing loads a lot across the region, so we size the fix to how your home actually runs.

Why does my heat pump blow cool air in heating mode?
Most often a stuck reversing valve, low refrigerant charge, or a defrost cycle that is running too long. Heat pumps also deliver air cooler than a furnace by design, so lukewarm can be normal while cold is not.
Is ice on the outdoor unit a problem?
A light frost that clears during defrost is normal. Thick ice covering the coil means the defrost board, sensor, or charge needs attention. Turn the system off and call us before the compressor takes damage.
Should I switch to emergency heat?
You can use it to keep the house warm short term, but emergency heat runs the backup strips only and costs more to operate. Treat it as a stopgap and schedule heating repair rather than leaving it there.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what you notice. Warm air, no air, short cycling, a smell, a noise. Details like when it started help us bring the right parts on the first visit.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, refrigerant performance, airflow and the return sizing. We test rather than guess, then explain what failed and why in plain language before any work starts.
- Step 3
Repair and verify
We make the repair, then measure temperatures and airflow at the vents to confirm the system holds. If a duct or return is starving the equipment, we tell you what it would take to fix it.

Why homeowners call us
- We know stucco tract homesMuch of the housing we service was built fast with returns too small for the tonnage installed. That single duct in the hallway explains a lot of weak airflow complaints, and we look at it before we sell you equipment.
- Marine mornings, inland afternoonsCoastal condos fight humidity and salt air, while inland homes run long afternoon cycles in triple digits. Same system, different failure patterns. We set expectations for the climate your house actually sits in.
- Diagnosis you can followYou get told which part failed, what it does and what happens if it waits. No hurry, no scare talk. If the honest answer is that the system has a few seasons left, we say that.
- Repair before replacementMost calls end in a repair, not a new system. We quote replacement only when a repair will not hold or the cost stops making sense, and we explain the reasoning either way.
