Heat Pump Repair Services for Delano Homes
A heat pump does two jobs with one set of parts. It cools through Delano's 100-degree summers, then reverses to heat through fog season. Because it works almost all year, small faults build up and show in whichever mode it's running.
Our heat pump repair services follow one rule: run the system in heat and in cool before touching a part. A reversing valve that sticks in January can look like a refrigerant leak, and a defrost sensor that fails in fog season can look like a bad thermostat. Testing both modes is how we tell them apart, whether the heat pump is a split system with an air handler in the attic, a packaged unit beside a manufactured home, or the outdoor half of a dual-fuel setup.
Heat pump setups we test in both modes
- Split System With an air handler in the attic
- Packaged Unit Beside a manufactured home
- Dual-Fuel Setup The outdoor half, paired with a gas furnace
Heat Pump Not Heating, Not Cooling or Blowing Cold Air?
Some things that look like faults are normal for a heat pump. Use this list to tell the difference, then book a repair if your system matches the second line.
- Can be normal
- Book a repair
- Often traced to
-
Blowing cool air in heat mode
- Can be normal A short burst of cool air during defrost, or air that feels lukewarm because heat pump air is cooler than furnace air.
- Book a repair The air stays cool for more than a few minutes, or the house loses temperature.
- Often traced to A stuck reversing valve, low refrigerant, a failed defrost control, or the thermostat calling for the wrong mode.
-
Not cooling in summer
- Can be normal The house lags a few degrees behind on 105-degree afternoons.
- Book a repair Warm air from the vents, or the system runs all day and never reaches the setting.
- Often traced to A dirty outdoor coil, a failed capacitor or fan motor, low refrigerant, or a valve stuck in heat.
-
Ice on the outdoor unit
- Can be normal A light white frost on cold, foggy mornings that clears during defrost.
- Book a repair Thick ice, ice on one side only, ice on the refrigerant lines, or ice that never clears.
- Often traced to A defrost sensor or board, low refrigerant, an outdoor fan problem, or blocked airflow.

Aux or emergency heat light stays on
- Can be normal The light comes on briefly during defrost or after you raise the thermostat several degrees.
- Book a repair It stays on for hours in mild weather, or your SCE bill jumps.
- Often traced to A heat pump that can't keep up because of low charge, a defrost fault, or a thermostat setup problem.
-
Runs constantly or short cycles

Fog Season vs Summer: How Heat Pump Repairs Differ in Delano
Summer
Long runs in triple-digit heat wear out capacitors, contactors and fan motors. Dust from the fields and Highway 99 coats the outdoor coil, which raises pressure and heat inside the compressor. Most summer repairs start with a dirty coil or a weak electrical part.
Fog season
Tule fog settles over the valley from about November through March, sometimes for days at a time. The outdoor coil runs below freezing in that damp air, so frost builds fast and defrost runs often. A weak defrost sensor, low charge or a slow fan shows up first in winter, as ice, cool air or an aux light that won't go off.
The switchover
The first cold mornings after months of cooling are when a sticking reversing valve or a mis-set thermostat usually shows itself. If your heat pump ran fine all summer but won't heat in November, that's a common pattern, not bad luck.
Frost, Ice and a Frozen Outdoor Unit
In heat mode, the outdoor coil gets colder than the air around it. In Delano's foggy winter air, moisture freezes onto it. The heat pump handles this with a defrost cycle: it briefly switches to cooling mode to warm the coil, the outdoor fan stops, and you may hear a whoosh and see steam. Most systems do this every 30 to 90 minutes as needed.
What to do
-
Turn the system to off or emergency heat.
-
Clear any leaves or debris from around the unit.
-
Never chip at ice, because the coil fins bend easily.

Then book a repair.

The usual causes are a failed defrost sensor or board, low refrigerant, a weak outdoor fan, or a dirty coil.
Aux Heat and the Emergency Heat Light
Aux heat
Aux heat is the backup heat in your system. On most Delano heat pumps it's electric heat strips in the indoor unit; on dual-fuel systems it's the gas furnace. The thermostat turns it on by itself during defrost, on cold nights, or when you raise the setting by more than a few degrees.
Emergency heat
Emergency heat is a setting you choose. It shuts off the heat pump and runs only the backup heat. Use it if the outdoor unit is iced over or making a bad noise, and book a repair, because heat strips cost much more to run.
When the light points to a fault
- Aux heat shows on for hours on mild days in the 40s or 50s
- Your SCE bill rises sharply in a month with normal weather
- The thermostat says aux or emergency heat when you didn't set it
That pattern usually means the heat pump isn't carrying the load, often from low refrigerant, a defrost fault, or a thermostat wired or set up as if the system were a furnace.
Dual-Fuel Systems: The Heat Pump Side
A dual-fuel system pairs a heat pump with a gas furnace. The heat pump handles mild weather, and the thermostat switches to the furnace below a set outdoor temperature, called the balance point.
We repair the heat pump half:
- The outdoor unit
- Defrost
- Refrigerant
- The controls that decide when to switch
-
A balance point set too high, so the furnace runs most of the winter
-
A failed outdoor temperature sensor
-
A thermostat that never hands back to the heat pump

Is This Heat Pump Worth Fixing?
Repair usually makes sense when:
- The fault is one part, such as a capacitor, sensor, fan motor or defrost board
- The system is under about 10 years old and still heats and cools evenly
- It uses R-410A or a newer refrigerant
Replacing may be better when:
- The heat pump is around 15 years old or more
- It needs a compressor, a reversing valve, or a large refrigerant repair
- It still uses R-22, which is no longer made
- It has had several repairs in the last couple of years
On a heat pump, the deciding part is usually the compressor or the reversing valve. Both sit inside the sealed refrigerant circuit, so either repair also means recovering and recharging the refrigerant. When one of them fails on an older R-22 system, weigh that repair against what installing a new heat pump involves before you decide.
Heat Pump Repair Cost: Electrical Parts vs Sealed-System Work
The biggest cost split on a heat pump is whether the repair stays on the electrical side or opens the refrigerant circuit.
-
Electrical
Lower end
- Capacitors
- Contactors
- Thermostat setup
- A defrost sensor
- A cleared drain
-
Motors & boards
Middle
- Fan and blower motors
- Defrost or control boards
- A small leak repair and recharge
-
Sealed system
Higher end

- A compressor
- Coil replacement
What moves the price
- The part A small sensor and a compressor are very different jobs
- Refrigerant type Older R-22 systems cost more to recharge
- Access Packaged units on the ground are quicker to reach than an air handler in a tight attic
- System age Older parts can be harder to find

Request a Heat Pump Repair VisitWhen a Heat Pump Repair Involves Permits or Refrigerant Rules
-
01
Permits
Most repairs, such as replacing a capacitor, motor or sensor, don't need a permit. Replacing the outdoor unit or the whole system needs a mechanical permit from the City of Delano or Kern County. If your repair might cross that line, ask our team how the permit would be handled.
-
02
Refrigerant
Only EPA Section 608 certified technicians may handle refrigerant. R-410A is still available for repairing existing systems. R-22 is no longer made, so an R-22 leak can push the repair-or-replace decision. When equipment is replaced, California's Title 24 energy code can require the refrigerant charge to be verified.
-
03
Licensing
A heat pump repair with refrigerant work and parts can pass California's $1,000 threshold for labor and materials, and above that the work must be done by a contractor licensed with the Contractors State License Board. You can look up any contractor on the CSLB website.
Other Systems and Sudden Breakdowns
-
Sudden breakdown
If your heat pump has stopped completely, is tripping its breaker or smells like it's burning, use emergency heat pump repair. - For a ductless system, see mini split repair.
- For a central air conditioner with no heat pump, see AC repair.
- For a gas furnace or the gas side of a dual-fuel system, see furnace repair.

Heat Pump Repair Questions: Cold Air, Ice and Aux Heat
Why is my heat pump blowing cold air in heat mode?
A short burst of cool air during a defrost cycle is normal, and heat pump air always feels cooler than furnace air. If the air stays cool for more than a few minutes, the usual causes are a reversing valve stuck in cooling, low refrigerant, a failed defrost control, or a thermostat calling for the wrong mode.
Is ice on my outdoor unit normal in winter?
Light white frost on foggy Delano mornings is normal and should clear during defrost. Thick ice, ice on only one side, ice on the refrigerant lines, or ice that never clears points to a defrost, refrigerant or fan problem. Switch the system off or to emergency heat and book a repair. Don't chip at the ice.
Why is the aux or emergency heat light on?
Aux heat comes on by itself during defrost, on cold nights, or when you raise the thermostat several degrees. If it stays on for hours in mild weather, the heat pump likely isn't carrying the load, often because of low refrigerant, a defrost fault, or a thermostat setup problem.
Should I switch to emergency heat?
Use emergency heat only if the outdoor unit is iced over, making a grinding or banging noise, or has stopped running. It shuts off the heat pump and runs only the backup heat, which costs more to run, so book a repair soon after.
Why won't my heat pump cool in the summer?
In Delano, the most common causes are a dusty outdoor coil, a failed capacitor or fan motor, low refrigerant, or a reversing valve stuck in heat. A system that lags a few degrees on 105-degree afternoons may be normal. Warm air from the vents is not.
Do you repair packaged heat pumps on manufactured homes?
Yes. We repair packaged heat pumps, where the whole system sits in one outdoor cabinet, including the units on manufactured homes in Cypress Gardens and homes without attic space.
Do you repair dual-fuel systems?
Yes, we repair the heat pump side of a dual-fuel system: the outdoor unit, defrost, refrigerant, and the controls that switch between the heat pump and the furnace. Gas-side problems such as ignition or the flame sensor are handled as furnace repair.
How much does heat pump repair cost in Delano?
It depends on the part that failed, the refrigerant type, the system's age and how easy the unit is to reach. A capacitor or thermostat repair costs far less than a reversing valve or compressor. You get the price before any repair starts. For actual prices, connect with our professionals.
Which heat pump brands do you repair?
Brands we service include Carrier, Goodman, Lennox, Trane, Bryant, Daikin, Rheem, York and American Standard.
Is it worth repairing an older heat pump?
Often, yes, if the problem is one part and the system still heats and cools well. If the heat pump is around 15 years old, uses R-22 refrigerant, or needs a compressor or another major repair, replacing it may make more sense. We'll show you both options.
