Heat pump systems are efficient, but when they fail, you lose both heating and cooling. I provide honest, practical diagnostics and repairs for all major brands in Brentwood, focusing on getting your system back to work without unnecessary parts or sales pressure.
Heat Pump Repair & Service in Brentwood
LC Heating & Air provides heat pump repair in Brentwood — 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.
We repair and service all major HVAC brands in Brentwood, including Carrier, Trane, Lennox, Daikin, Mitsubishi, and Goodman, and older or discontinued units. No matter the manufacturer, we diagnose the problem accurately and give you an upfront price before any work begins.
Brentwood is a unique place to work, from the quiet streets of Brentwood Glen to the hillside homes in Mandeville Canyon. Because of our coastal-adjacent microclimate, your heat pump works hard to manage both the marine layer's humidity and the sudden heat of a Santa Ana wind event. When your system stops working, you don't need a sales pitch; you need a technician who understands how these specific units operate.
I am Leo, owner of LC Heating & Air. I handle all diagnostics and repairs personally, ensuring that when I look at your system, you get a straight answer about what is wrong and whether a repair makes financial sense. We are fully licensed (CSLB #1073586) and provide written, flat-rate estimates before we turn a single wrench.

Common Heat Pump Issues in Brentwood
In Brentwood, I frequently see heat pumps struggling with reversing valve failures. This is the component that tells your unit to switch between heating and cooling. If it gets stuck, you might find your home cooling when you want heat, or vice versa. Because many homes here use rooftop package units or compact mechanical closets, access can be tricky, but I have the tools and experience to reach these systems safely.
I also see many systems suffering from defrost board failures. During cooler nights, your outdoor unit should periodically melt frost off the coils. If you see your unit encased in ice, the defrost cycle isn't working. Ignoring this can lead to compressor damage, which is a much more expensive problem to fix than a simple board replacement.
Working with Brentwood's Diverse Housing
Brentwood's housing stock is varied, ranging from mid-century ranch homes to modern luxury condos and large hillside estates. Whether you are in a mixed-use building near the San Vicente Corridor or a private home in Crestwood Hills, I understand the logistical challenges of the area. I am experienced in coordinating with HOAs and building management for rooftop access and parking limitations.
For larger estate homes, I often see multi-zone systems that have become unbalanced. If your system is running but the temperature isn't consistent across your home, it is often a ductwork or zoning issue rather than a mechanical failure. I look at the whole system, not just the unit, to ensure your comfort.
My Diagnostic Process
When I arrive, I don't guess. I test your heat pump in both heating and cooling modes. I measure refrigerant pressures and check the electrical components—capacitors, contactors, and the defrost board. This allows me to see exactly where the failure is occurring.
Once I have the facts, I sit down with you to explain what I found. I provide a written, flat-rate estimate. You will know exactly what the repair costs before I start. If the system is worth repairing, I will tell you. If the pattern of failure suggests that a replacement is a better long-term investment, I will explain why so you can make an informed decision.
Repair vs. Replacement: An Honest Look
Homeowners often ask me if they should repair an older unit or just replace it. My answer depends on the condition of the compressor and the age of the system. If a simple part like a capacitor or a defrost board is the culprit, a repair is usually the right path. However, if the compressor is failing or the refrigerant circuit has a major leak in an aging system, the cost of repair might be better spent toward a new, high-efficiency unit.
I don't push for replacement unless it is truly the most sensible financial move for you. My goal is to provide a repair that lasts, not a temporary fix that leads to more service calls in a few months.
Understanding Costs and Rebates
I believe in transparency. My diagnostic fee is $125–$175, and I provide a clear, written estimate for any necessary repairs. Component repairs typically range from $200 to $650 depending on the part and the labor involved.
If your system is beyond repair, I can guide you through the installation process. New heat pump installations range from $7,000 to $16,000, and there are often rebates available, such as the TECH Clean CA program, which can provide significant savings after installation. I will help you understand what you qualify for so there are no surprises.
Scheduling and Access
I know that living in Brentwood often means dealing with tight parking, shared walls, and strict building access windows. I prioritize clear communication regarding my arrival time. If your building requires specific insurance documentation or elevator access for rooftop equipment, let me know when you book, and I will make sure we are prepared.
I offer same-day service options because I know that being without heat or cooling in our climate is a major disruption. I carry common heat pump parts on my truck to minimize the need for return trips.
Common Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor coils with tools. This can puncture the aluminum fins and cause a refrigerant leak, turning a simple defrost issue into a very expensive repair. If your unit is iced over, turn it off and let it thaw, or call me to diagnose the underlying cause.
Another mistake is ignoring the 'Emergency Heat' setting on your thermostat. If you see your system running on 'AUX' or 'EM HEAT' for days at a time, your heat pump isn't doing the work. You are essentially heating your home with a giant space heater, which will cause your electric bill to spike. If you see this, call for service right away.
Health and Safety
Your safety is my priority. A malfunctioning heat pump can lead to electrical issues or poor indoor air quality if the ductwork is compromised. I ensure all electrical connections are tight and that the system is operating within safe pressure limits. I also check that your thermostat is correctly configured to prevent the system from overworking.
I am fully licensed and insured, so you can have peace of mind while I am working in your home. I keep my workspace clean and respect your property as if it were my own.

What Brentwood customers say about heat pump repair
Verified reviews from homeowners in Brentwood and nearby neighborhoods who used our heat pump repair service.
“LC installed a Nest thermostat and programmed it for our schedule. They also found that our secondary heat exchanger had a small crack during the check-in — caught a potential CO issue before it became dangerous.”
“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.”
