LC Heating & Air provides heat pump repair in Hawthorne for year-round comfort. A heat pump heats in winter and cools in summer, replacing both your gas furnace and air conditioner. We install and repair central heat pumps, ductless mini split heat pumps, cold-climate heat pumps, and dual-fuel systems, and we help you stack TECH Clean California rebates, the federal 25C tax credit, and SCE incentives. Whether you are searching for heat pump not heating, heat pump not cooling, heat pump installation and repair, or heat pump replacement cost, call (323) 970-3113 for same-day service and a no-pressure estimate.

Heat pump systems are efficient, but they are more complex than standard air conditioners. Because they handle both heating and cooling, a failure in one mode often points to a specific component like a reversing valve or a defrost board. At LC Heating & Air, we don't guess; we test.
Whether you're in a single-family home or a multifamily building in Hawthorne, we understand how local conditions—like dust and coastal air—affect your equipment. We provide same-day service and clear, written estimates so you know exactly what you're paying for before we start the work.

Common Heat Pump Issues in Hawthorne
In our area, I frequently see heat pumps that provide cooling but fail to heat, or vice versa. This is often a symptom of a stuck reversing valve. Because Hawthorne homes vary in age, we often find that older electrical layouts or restricted airflow in attic ducts can make these problems worse.
Another common issue is ice buildup on the outdoor unit. While a little frost is normal during a cold snap, a unit completely encased in ice usually means the defrost cycle isn't working. We check your defrost board, refrigerant levels, and airflow to find the root cause, not just the symptom.
Understanding Your Hawthorne Home's System
Hawthorne has a mix of housing, from older single-family homes to newer remodels. Your HVAC system's performance depends heavily on the ductwork and electrical capacity of your specific building. Before I recommend a repair or a replacement, I look at how your equipment is placed and whether your current ductwork can actually support the system's output.
If your system is struggling, it might not be the unit itself—it could be the airflow. I always check these factors because a new unit won't fix a ductwork problem, and a simple repair might be all you need if the system is otherwise sound.
My Diagnostic Process
When I arrive at your home, I don't just look at the thermostat. I test your system in both heating and cooling modes. This is critical for heat pumps because the reversing valve has to switch the refrigerant flow correctly for both.
I measure refrigerant pressures, check your capacitors and contactors, and inspect the defrost board. Once I have the full picture, I sit down with you to explain what I found and provide a written, flat-rate estimate. You decide how to proceed from there.
Repair vs. Replacement: An Honest Look
I get asked all the time: 'Leo, should I fix this or just get a new one?' My answer depends on the condition of your equipment and the cost of the repair. If it's a simple capacitor or a contactor, a repair is almost always the right move.
However, if the compressor is failing or the repair costs are high on an aging, inefficient unit, I'll tell you that replacement might be the better long-term investment. I'm not here to sell you a new system if your current one has plenty of life left.
Costs and Rebates
We believe in transparency. Our diagnostic fee is $125–$175. Common repairs like capacitors range from $150–$350, while more involved work like a reversing valve replacement is $400–$650. If you do need a full system replacement, costs typically range from $7,000–$16,000 before rebates.
There are programs like the TECH Clean CA rebate that can offer $1,500 to $3,000 back after installation. We will help you understand if your project qualifies so you can make an informed decision.
Health and Safety First
Your HVAC system is vital for your home's air quality and comfort. If your heat pump fails in the winter, you might be tempted to run the emergency heat setting for a long time. While this provides heat, it uses significantly more electricity and can cause a massive spike in your utility bill.
If your system is tripping breakers or making grinding noises, turn it off and give us a call. We prioritize safety and will make sure your system is running correctly and efficiently before we leave your property.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor coils. Please don't do this. You can easily puncture the aluminum fins and cause a refrigerant leak, which is a much more expensive repair.
Another mistake is ignoring the 'AUX HEAT' or 'EM HEAT' light on your thermostat. If that light stays on during mild Hawthorne weather, your heat pump isn't doing the heavy lifting, and you're paying for expensive resistance heat. Get it checked early.

Common Heat Pump Issues & Diagnostic Guide in Hawthorne
Understanding these common system symptoms helps identify whether a simple fix or a professional repair is needed.
Not heating/cooling properly
Typical Cause: Reversing valve failure, refrigerant leak, or failed outdoor fan motor
Quick Action: Verify system mode on thermostat and check outdoor unit circuit breaker
Outdoor unit iced up in summer
Typical Cause: Severe restriction of airflow or low refrigerant pressure in coil
Quick Action: Shut off system immediately and allow coil to defrost
Compressor not starting
Typical Cause: Failed start capacitor, blown contactor, or electrical disconnect issue
Quick Action: Check indoor breaker panel; do not try to force start the unit
High electricity bill
Typical Cause: Unit running continuously due to dirty coils or thinned refrigerant charge
Quick Action: Perform annual maintenance tune-up and check for duct leaks
Making the Right Choice for Your Home
Choosing between a repair and a replacement is a big decision. I look at the age of your system, the frequency of repairs, and the overall efficiency. If your system is relatively new, a repair is usually the best path.
If you're constantly calling for repairs on an older unit, it might be time to look at a new, high-efficiency heat pump. I'll give you the facts so you can decide what makes the most sense for your budget and your home.

What Hawthorne customers say about heat pump repair
Verified reviews from homeowners in Hawthorne and nearby neighborhoods who used our heat pump repair service.
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
“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.”
