I am Leo, owner of LC Heating & Air. If your heat pump is acting up, I provide honest, practical diagnosis and repair for all brands. I don't believe in guessing—I test the system in both heating and cooling modes to find the real problem.
Heat Pump Repair & Service in Pacoima
LC Heating & Air provides heat pump repair in Pacoima — including heat pump services, heat pump not heating, heat pump replacement, energy efficient heat pump. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.

Heat pump systems are efficient, but they are complex. Because they handle both heating and cooling, a failure in one mode often points to a component that affects the entire system. Whether you are dealing with a reversing valve that won't switch or an outdoor unit that is stuck in a defrost cycle, you need a technician who understands how these specific parts interact.
At LC Heating & Air, I serve homeowners in Pacoima with a focus on getting your system back to work without unnecessary parts replacement. I provide a written, flat-rate estimate before I start any work, so you know exactly what you are paying for. If your system is worth fixing, I will fix it. If it is time to replace it, I will tell you why.

Common Heat Pump Issues in Pacoima
Pacoima's climate puts a lot of stress on HVAC equipment. With long summer run times and 95-100 degree days, outdoor units get dusty and overworked. This heat, combined with attic temperatures, can lead to premature component failure. I often see systems struggling with airflow issues caused by clogged filters or ductwork that wasn't sized for our valley heat.
Beyond the heat, I frequently see issues with defrost boards and reversing valves. When a heat pump is stuck in cooling mode during a cold snap, or if the outdoor unit is encased in ice, it is usually a specific electrical or mechanical failure that needs a targeted repair, not a whole new system.
Working with Pacoima Homes
Pacoima has a mix of mid-century ranch houses and larger remodels. Many of these homes rely on attic-based duct systems. When I service a heat pump here, I have to look at the whole picture—not just the unit outside. The attic heat and the condition of your existing ducts directly impact how hard your heat pump has to work.
I pay close attention to electrical capacity and condenser clearance. If your outdoor unit is crowded by vegetation or debris, it cannot breathe, which leads to higher energy bills and potential compressor damage. I check these details during every visit to ensure your repair lasts.
My Diagnostic Process
I don't just look at the thermostat and guess. My process starts with testing the system in both heating and cooling modes. I measure refrigerant pressures and check the electrical components like the contactor and capacitor. If the system is clicking or failing to start, I need to see if the issue is a simple electrical fault or something deeper in the refrigerant circuit.
Once I identify the fault, I provide a written estimate. I explain what I found, why it happened, and what the repair involves. You approve the price before I touch the equipment.
Repair vs. Replace: An Honest Look
Homeowners often ask me if they should just replace an old unit. My answer depends on the condition of the compressor and the age of the system. If a reversing valve or a defrost board fails on a unit that is otherwise in good shape, a repair is usually the smart move. These are specific, replaceable parts.
However, if the compressor is failing or the system has multiple leaks, a repair might just be throwing good money after bad. I will give you the facts so you can decide if a repair is enough to get you through the season or if replacement is the more reliable long-term choice.
Costs and Rebates
I believe in transparent pricing. A standard heat pump diagnostic is $125–$175. Common repairs like a capacitor replacement range from $150–$350, while a reversing valve or defrost board replacement typically falls between $300–$650. If you do end up needing a full system replacement, costs range from $7,000–$16,000 before any available rebates.
For those looking at replacement, there are programs like the TECH Clean CA rebate, which can offer $1,500 to $3,000 back after installation. I can help you understand if your project qualifies so you can factor that into your decision.
Health and Safety
Your HVAC system affects the air quality and safety of your home. A heat pump that isn't defrosting correctly can lead to moisture issues, and a system running on emergency heat strips can cause a massive spike in your electric bill. I check for proper airflow and electrical safety during every service call.
If your system is tripping breakers or making grinding noises, turn it off and call me. It is better to have a professional look at it than to risk a fire or further damage to the compressor.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor coils. Please don't do this—you will likely puncture the aluminum fins and cause a refrigerant leak, which is a much more expensive repair. Also, don't ignore a system that is constantly running on 'Emergency Heat.' It is a sign that your heat pump isn't doing its job, and it will cost you a fortune in electricity.
Another common issue is neglecting the outdoor unit. If it is covered in dust or blocked by plants, it cannot transfer heat efficiently. Keep the area around your unit clear.
Scheduling Your Service
I am a local contractor, not a big corporate franchise. When you call (323) 970-3113, you are reaching LC Heating & Air directly. I prioritize same-day service for heat pump failures because I know how uncomfortable it is to be without heating or cooling in our climate.
When I arrive, I will need access to your attic, your thermostat, and the outdoor condenser unit. Having these areas clear helps me get to work faster and provide a more accurate diagnosis.
Is Your Heat Pump Worth Repairing?
If your heat pump is less than 10-12 years old and the repair is a single component like a capacitor, contactor, or defrost board, it is usually worth fixing. These parts are designed to be replaced.
If the repair involves the compressor or a major refrigerant leak in an older unit, I will be honest with you about the risks. I would rather you spend your money on a system that will actually last than on a repair that is just a temporary fix.
How the visit works
We test the system in both heating and cooling modes, measure refrigerant pressures in both modes, and identify the specific fault.
We test capacitors, contactors, reversing valve, defrost board, and refrigerant circuit components 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.

What Pacoima customers say about heat pump repair
Verified reviews from homeowners in Pacoima and nearby neighborhoods who used our heat pump repair service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Called on a Saturday because AC was blowing warm air. LC answered, sent someone the same afternoon. They found and fixed a refrigerant leak. Professional and reasonably priced.”
“Woke up to no AC at 6am. LC was at my door by 9am. Frozen evaporator coil — they explained exactly why it happened (dirty filter + low airflow) and fixed it same visit. Very professional.”
