Heat Pump Repair & Service in Alhambra
LC Heating & Air provides heat pump repair in Alhambra — including heat pump services, heat pump not heating, heat pump replacement, energy efficient heat pump.

We repair and service all major HVAC brands in Alhambra, 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.
Heat pump systems are unique because they handle both heating and cooling in a single unit. When they fail, it often affects both functions, which is why you need a technician who understands the reversing valve and defrost cycles, not just standard AC components.

Local HVAC considerations
Common Heat Pump Issues in Alhambra
In Alhambra, our long summer run times and 95-100 degree days put significant stress on cooling equipment. Heat pumps here often struggle with airflow issues caused by dusty conditions and attic heat, which can lead to premature component failure.
We frequently see systems that have been misdiagnosed by others because they didn't check the reversing valve or the defrost board. If your system is stuck in one mode or the outdoor unit is encased in ice, it is usually a specific component failure rather than a need for a full system replacement.
Alhambra Housing and HVAC Systems
Alhambra’s housing stock ranges from classic mid-century ranch houses to larger, modern remodels. Many of these homes rely on attic-based duct systems. When we service a heat pump in an Alhambra attic, we pay close attention to duct condition and electrical capacity.
Older homes often have different electrical requirements than modern high-load cooling systems. Before we recommend any repair or replacement, we verify that your current electrical setup can safely handle the equipment demands.
Our Diagnostic Process
I don't believe in guessing. When I arrive at your home, I test the system in both heating and cooling modes. This is critical for heat pumps because a fault in the reversing valve might only show up when the system tries to switch cycles.
We check your refrigerant pressures, test the defrost board, and inspect the contactors and capacitors. Once I have the full picture, I explain the issue to you in plain English and provide a written flat-rate estimate. You decide how to proceed.
Repair vs. Replacement
A lot of companies will push for a full replacement the moment a heat pump hits a certain age. I take a different approach. If a component like a reversing valve or a defrost board is the culprit, a repair is often the most practical and honest solution.
However, if the compressor is failing or the refrigerant circuit is compromised beyond reasonable repair, I will tell you that honestly. My goal is to provide a solution that makes sense for your home and your budget, not to sell you equipment you don't need.
Costs and Rebates
We provide transparent pricing for all our services. A standard diagnostic is $125–$175, and most component repairs range from $200–$650. If you do end up needing a full system replacement, we can discuss the TECH Clean CA rebates, which can range from $1,500 to $3,000 depending on the installation.
We always provide a written estimate before starting any work so there are no surprises on your final bill.
Scheduling and Access
We offer same-day service for heat pump repairs. When you call (323) 970-3113, we coordinate a time that works for you. We are mindful of your property and always ensure that attic access and outdoor condenser clearance are handled safely and professionally.
Being a local contractor means we are familiar with the logistics of Alhambra neighborhoods and can get to you quickly when your system goes down.
Mistakes to Avoid
One of the biggest mistakes homeowners make is trying to chip ice off the outdoor coil with a tool. This can puncture the aluminum fins and cause a refrigerant leak, turning a simple defrost board repair into a much more expensive project.
Another mistake is ignoring the 'AUX HEAT' or 'EM HEAT' light on your thermostat. If this light stays on during mild weather, your heat pump is likely failing to heat on its own, and you are paying for expensive electric resistance heating.
Health and Safety
Your safety is our priority. We ensure all electrical connections are secure and that your system is operating within safe pressure limits. If your system is tripping breakers, do not keep resetting them; that is a sign of an electrical fault that needs immediate attention.
We are fully licensed (CSLB #1073586) and insured, so you can have peace of mind knowing the work is being done by a qualified professional.
Making the Right Decision for Your Home
Choosing between a repair and a replacement is a big decision. I look at the age of the unit, the cost of the repair, and the overall condition of the system. If the repair is straightforward and the unit is otherwise in good shape, I will recommend the repair.
If the system is constantly breaking down or the cost of the repair is a significant portion of a new unit, we will talk about replacement options. My job is to give you the facts so you can make the decision that is best for your family.

What Alhambra customers say about heat pump repair
Verified reviews from homeowners in Alhambra 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.”
