LC Heating & Air provides expert heat pump diagnosis and repair for all major brands across Los Angeles. We focus on getting your system running right, whether it's a simple component fix or a complex refrigerant issue.
Heat pump systems are unique because they handle both heating and cooling in one unit. When they fail, it often affects both modes, which can be frustrating for homeowners. At LC Heating & Air, I focus on diagnosing the root cause of the failure rather than just swapping parts.
Whether your system is stuck in cooling mode, icing over in the winter, or just not putting out the air it should, I provide a clear, honest assessment. I am a licensed contractor (CSLB #1073586) serving Los Angeles, and I believe in giving you a written estimate before any work begins.

Common Heat Pump Issues in Los Angeles
In Los Angeles, we see a lot of heat pumps struggling with the local climate, especially with dust buildup and the demands of mixed-age housing. A common issue is the reversing valve getting stuck, which leaves the system trapped in either heating or cooling mode regardless of what you set on the thermostat.
Another pattern I see frequently involves defrost board failures. Because our winters are mild, homeowners often don't notice a defrost issue until the outdoor unit is completely encased in ice. If your system is running but the outdoor coil looks like a block of ice, that is a clear sign the defrost cycle isn't doing its job.
Working with Los Angeles Homes
Los Angeles has a wide variety of housing, from older single-family homes to newer multifamily buildings. This variety means that heat pump installations are rarely identical. I often find that older electrical layouts or restricted ductwork can impact how a heat pump performs.
Before I recommend a repair or a replacement, I look at the whole picture: the condition of your existing ducts, the electrical capacity, and how the equipment is placed. This helps ensure that any repair I perform actually solves the problem rather than just masking it.
My Diagnostic Process
I don't believe in guessing. When I arrive, I test your heat pump in both heating and cooling modes. This is critical because a component might work fine in one mode but fail in the other. I measure refrigerant pressures, check the electrical components like capacitors and contactors, and verify that the defrost board is functioning.
Once I have the data, I explain exactly what I found. I will tell you if a part needs replacing and give you a flat-rate price for the repair. You will know exactly what you are paying for before I pick up a tool.
Repair vs. Replacement: Making the Right Call
I am often asked if it is better to fix an old unit or buy a new one. My answer is always based on the condition of the equipment. If the repair is straightforward—like a capacitor, contactor, or a faulty board—and the unit is otherwise in good shape, a repair is usually the right move.
However, if the compressor is failing or the refrigerant system has a major leak in an inaccessible area, the cost of repair might not make sense compared to the long-term efficiency of a new system. I will give you the facts so you can make the decision that fits your budget and your home.
Costs and Rebates
I keep my pricing transparent. A diagnostic visit is $125–$175. Common repairs like a capacitor or defrost board replacement typically range from $200 to $650 depending on the specific part and labor involved. If a full system replacement is necessary, those projects range from $7,000 to $16,000 before any available rebates.
For those looking at new installations, programs like the TECH Clean CA rebate can offer significant savings, sometimes ranging from $1,500 to $3,000 after the installation is complete. I can help you understand if your project qualifies for these incentives.
Access and Scheduling
I know your time is valuable. I prioritize same-day service for heat pump issues because I know how uncomfortable it is to be without heating or cooling. When I schedule a visit, I make sure to account for the time needed to properly inspect your system, including checking attic access or tight equipment spaces.
If you are in Los Angeles, give me a call at (323) 970-3113. We will get you on the schedule and get your system back in working order.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor unit with a screwdriver or pouring hot water on it. This almost always damages the aluminum fins and can lead to much more expensive repairs. If your unit is iced over, turn it off and let it thaw naturally or call me to diagnose the underlying cause.
Another mistake is ignoring the 'Emergency Heat' light on your thermostat. If you see that light on, it means your heat pump isn't doing the work and your backup electric strips are running. This will cause your electric bill to spike, and it is a sign that your system needs professional attention immediately.
Health and Safety
Your home's air quality and safety are my priority. A failing heat pump can lead to poor airflow, which allows dust and allergens to settle in your ducts. Furthermore, electrical issues within the unit—like a failing contactor—can pose a fire risk if left unaddressed.
I always check the electrical connections and the overall safety of the unit during my diagnostic. My goal is to ensure that when I leave, your system is not only cooling or heating correctly but is also operating safely for your family.
Is It Time for a Repair?
If your heat pump is making strange noises, not switching modes, or running up your electric bill, it is time for a professional look. I don't believe in high-pressure sales. I believe in showing you exactly what is wrong and letting you decide the best path forward.
If the system is worth repairing, I will fix it. If the pattern points to replacement, I will explain why. That is the honest way to do business in Los Angeles.
How the visit works
We test the system in both heating and cooling modes, measure refrigerant pressures, and identify the specific fault.
We test capacitors, contactors, the reversing valve, and the defrost board as indicated by the diagnostic.
We explain the fault and provide a flat repair price. You approve; we repair.
We complete the repair and test both heating and cooling operation before leaving.
Cost factors we review before quoting
- • Type of component failure (reversing valve vs. capacitor)
- • Age and condition of the existing heat pump
- • Accessibility of the equipment
- • Refrigerant requirements
