LC Heating & Air provides expert heat pump diagnosis and repair for Larchmont residents. We handle everything from reversing valve failures to defrost board issues, ensuring your system runs reliably in both heating and cooling modes.
Larchmont Village and the surrounding neighborhoods like the Rossmore Avenue Corridor and the Third Street Area feature a beautiful mix of historic architecture. Many of these homes were built between 1920 and 1940, meaning central HVAC systems were often added as retrofits decades later. At LC Heating & Air, we understand that your home's character matters as much as its comfort. We provide practical, honest HVAC service from our base on Fairfax Avenue, ensuring your heat pump is repaired correctly without unnecessary upselling.
Heat pumps are unique because they handle both heating and cooling in one unit. When they fail, it often affects both modes. Whether you are dealing with a system stuck in cooling mode, an outdoor unit covered in ice, or a spike in your electric bill from the auxiliary heat running, we have the tools and parts to get it fixed. We are CSLB #1073586 and provide written, flat-rate estimates before we start any work.

Common Heat Pump Issues in Larchmont
In Larchmont, we see a lot of heat pumps struggling with the specific demands of our local climate and older housing stock. A common issue is the reversing valve failing, which leaves the system stuck in one mode—you might get cold air when you want heat, or vice versa. We also frequently see defrost board failures. Because our winters are mild but damp, if the defrost cycle isn't working, your outdoor unit can quickly become encased in ice, preventing the system from moving heat effectively.
Because many Larchmont homes were retrofitted with HVAC systems, we often find that the original electrical panels or ductwork aren't perfectly matched to the modern heat pump's requirements. We check your airflow, electrical capacity, and thermostat configuration during every diagnostic visit. This helps us determine if a simple component repair is all you need, or if the system's performance is being limited by the home's infrastructure.
HVAC in Historic Larchmont Homes
Larchmont's residential streets, from the Plymouth Boulevard area to the homes near Rossmore, are filled with Craftsman, Spanish Colonial, and Tudor Revival homes. These structures were not originally designed for modern HVAC. When we work on these properties, we are careful to respect the existing architecture. We often find that ductwork in these homes is undersized or located in tight attic spaces, which can restrict airflow and strain your heat pump.
Before we recommend any major repair or replacement, we look at the whole system. If your ducts are leaking or your electrical panel is maxed out, a new unit won't perform as expected. We believe in being honest about what your home can support. We won't sell you a high-efficiency system if your current ductwork can't handle the static pressure, and we will always tell you if a repair is the more practical choice for your specific situation.
Our Diagnostic Process
We don't guess. When we arrive at your Larchmont home, we perform a multi-mode diagnostic. We test your heat pump in both heating and cooling modes, measure refrigerant pressures, and check the electrical components like capacitors and contactors. This is the only way to know if a part has truly failed or if the issue is a symptom of a larger problem, like a refrigerant leak or a faulty thermostat setting.
Once we identify the fault, we provide a written, flat-rate estimate. You will know exactly what the repair costs before we pick up a tool. If we find that the system is worth repairing, we will do it. If the pattern of failure suggests that the unit is nearing the end of its life, we will explain why, showing you the data so you can make an informed decision for your home.
Repair or Replace?
Deciding whether to fix a heat pump or replace it is a big choice. If your heat pump is relatively new and suffers a common failure—like a bad capacitor, a stuck reversing valve, or a failed defrost board—a repair is usually the right path. We carry parts for all major brands, including Carrier, Lennox, Trane, and Mitsubishi, so we can often get you back up and running the same day.
However, if your system is older, uses outdated refrigerant, and requires a major repair like a compressor replacement, it might be time to look at a new unit. We will never push you toward a replacement if a repair will keep you comfortable for years to come. We look at the cost of the repair versus the age and efficiency of your current system to help you decide what makes the most sense for your budget.
Costs and Incentives
We believe in transparency. Our diagnostic fee is $125–$175, which covers the time we spend testing your system and identifying the issue. Common repairs like capacitor replacements typically range from $200–$650 depending on the complexity. If you do need a full system replacement, we will help you understand the costs, which generally range from $7,000–$16,000 before rebates.
For those looking at new installations, there are incentives like the TECH Clean CA rebate, which can offer between $1,500 and $3,000 back after installation. We will help you navigate these options so you aren't leaving money on the table. Our goal is to provide a clear path forward that fits your financial situation.
Safety First
Your safety is our priority. Heat pumps involve high-voltage electricity and pressurized refrigerant. We never recommend that homeowners attempt to repair these systems themselves. If your unit is iced over, please don't try to chip the ice away, as you can easily damage the aluminum fins and cause a leak. Instead, turn the system off and give us a call.
If you are stuck without heat during a cold snap, we can guide you on how to safely use your thermostat's emergency heat mode. This will keep you warm by using your backup resistance strips while we get out to your home to address the root cause of the heat pump failure.
Scheduling Service in Larchmont
We know your time is valuable. Being based on Fairfax Avenue allows us to serve Larchmont quickly. When you call (323) 970-3113, you are speaking with a local contractor who understands the logistics of our neighborhood. We check for access issues, electrical capacity, and equipment placement before we start any work, ensuring that we have everything we need to complete the job efficiently.
We offer same-day service options because we know that a broken HVAC system is more than just an inconvenience. We carry a wide range of parts on our trucks, including reversing valves and defrost boards, so we can often resolve the issue in a single visit.
Mistakes to Avoid
The biggest mistake we see is ignoring the early warning signs. A heat pump that is clicking, making grinding noises, or running in 'Aux Heat' mode constantly is telling you something is wrong. Ignoring these signs usually leads to a more expensive repair later, like a compressor failure, which is often the most costly part of the system.
Another common mistake is choosing a contractor based on a low 'teaser' price. We provide a flat-rate estimate for the actual repair. You won't find us charging for 'hidden' fees once we've opened up your unit. We believe in doing the job right the first time, which is why we test the system in both heating and cooling modes before we leave your property.
Making the Right Choice
When you're deciding between a repair and a replacement, look at the history of your system. If you've had us out three times in the last year for different issues, the system is likely telling you it's tired. On the other hand, if your unit is five years old and just needs a new capacitor, a repair is the smart, practical choice.
We are here to give you the facts, not a sales pitch. We will show you what we found, explain why it happened, and give you the price to fix it. You decide what works best for your home and your budget.

What Larchmont customers say about heat pump repair
Verified reviews from homeowners in Larchmont and nearby neighborhoods who used our heat pump repair service.
“Full system replacement in our 1930s Hancock Park home — not easy given the older construction. LC handled all the challenges: narrow access, old ductwork, low attic. Finished on time and on budget.”
“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.”
