Heat pumps are unique systems that handle both heating and cooling. When they fail, you need a technician who understands the reversing valve and defrost cycles, not just standard AC components. At LC Heating & Air, we provide honest, same-day diagnostics for all major heat pump brands in Montebello.

I'm Leo, owner of LC Heating & Air. I spend my days helping homeowners in Montebello get their systems running right. Heat pumps are great for our climate, but they are more complex than a standard AC unit. 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.
When I come out to your home, I don't just look for a quick fix. I test the system in both modes, check your refrigerant pressures, and look at the electrical components. My goal is to give you a clear, written estimate so you can decide if a repair makes sense or if the system has reached the end of its life. We are licensed (CSLB #1073586) and ready to help.
Emergency calls are answered within 30 minutes — call (323) 970-3113 for dispatch.

Common Heat Pump Issues in Montebello
In Montebello, our long summer run times and 95-100 degree days put a lot of stress on outdoor condensers. Dust buildup and attic heat can cause systems to work harder than they should. I frequently see heat pumps that have stopped switching between heating and cooling properly. This is often a reversing valve issue, which is a specific part that tells the system which way to move the refrigerant.
Another pattern I see is ice buildup on the outdoor unit. While a little frost is normal, a unit completely encased in ice usually means the defrost board has failed or there is an airflow problem in your attic ducts. I check these specific patterns first because they tell me exactly what is going on with your system.
Working with Montebello Homes
Montebello has a mix of single-family homes and mid-century ranch houses. Many of these homes rely on attic duct systems. When I'm inspecting your heat pump, I have to look at the duct condition and electrical capacity, because those factors affect how well your unit performs.
If your home has had a larger remodel, the cooling load might have changed. I look at how your current system handles the load of the house. If your ducts are leaky or undersized, even a brand-new heat pump won't keep you comfortable. I always explain how the house construction impacts the repair decision.
My Diagnostic Process
I don't guess. When I arrive, I start by 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 making a clicking noise, I check if it's the contactor closing or the reversing valve solenoid.
After I identify the fault, I write down a flat-rate estimate. I'll explain exactly what is broken and why. You'll know the cost before I touch the equipment. Once you approve, I perform the repair and then test the system again in both modes to make sure everything is working as it should.
Repair or Replace?
This is the most important conversation we have. If your heat pump is older and the repair is expensive—like a compressor failure—it might be time to look at a replacement. However, if it's a simple capacitor or a minor electrical issue, a repair is usually the right move.
I will never push you to replace a system that has plenty of life left. I'll give you the facts about your system's condition and help you weigh the cost of the repair against the potential for future breakdowns. My job is to give you the information you need to make the best decision for your home.
Costs and Rebates
I believe in being upfront about costs. A heat pump diagnostic is $125–$175. If you need a component repair, those typically range from $200–$650 depending on the part. If you do end up needing a full system installation, the cost ranges from $7,000–$16,000 before any rebates.
There are programs like the TECH Clean CA rebate, which can offer between $1,500 and $3,000 back after installation. I can help you understand if your project qualifies for these incentives so you can factor that into your final decision.
Access and Scheduling
When I schedule your service, I consider the logistics of your home. Attic access, the condition of your ducts, and the clearance around your outdoor condenser are all things I look at. If your unit is in a tight spot, it takes more time to service, and I want to make sure I have the right tools for the job.
I offer same-day service because I know how uncomfortable it is to be without heating or cooling in Montebello. I keep common parts like capacitors and defrost boards on my truck so I can often fix the problem in one visit.
Common Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor unit with a tool. This can puncture the aluminum fins and cause a refrigerant leak, which is a much more expensive repair. If your unit is iced over, just turn it off or run it in cooling mode if the weather is mild.
Another mistake is ignoring the 'AUX HEAT' or 'EM HEAT' light on your thermostat. If that light stays on, your system is using expensive backup strips instead of the heat pump. That will cause your electric bill to spike. If you see that light, give me a call so we can check if your heat pump is actually working.
Health and Safety
Your safety is my priority. Heat pumps involve high-voltage electrical components and pressurized refrigerant. I am a licensed C-20 contractor, which means I follow the safety standards required to handle these systems properly.
If your system is tripping the breaker, don't keep resetting it. That's a sign of an electrical fault that could be a fire hazard. Call me, and I'll come out to inspect the wiring and the compressor to make sure everything is safe before I turn it back on.
Making the Right Choice
When your heat pump stops working, you have a choice to make. You can repair it, or you can replace it. I'll look at the age of your system, the cost of the repair, and how well it's been maintained. If the repair is a simple fix, I'll tell you. If the system is failing in multiple ways, I'll explain why replacement might be the better long-term value.
I don't use high-pressure sales tactics. I give you the information, I give you a price, and I let you decide what's best for your family and your budget. That's how I've built my business in Montebello.

What Montebello customers say about heat pump repair
Verified reviews from homeowners in Montebello and nearby neighborhoods who used our heat pump repair service.
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
“Switched from gas furnace to a heat pump after talking to LC. They handled the TECH Clean California paperwork and we got a $2,500 rebate plus the federal tax credit. Total out of pocket was about $5,500 for a system that now heats and cools. Gas bill went to zero.”
“We were skeptical about a heat pump for heating in the winter but LC explained the technology clearly. After one winter season, our home stays warmer than it ever did with the old furnace, and it's quieter too.”
