Heat pump systems combine the functions of an air conditioner and a furnace in one unit — which means heat pump failure affects both heating and cooling simultaneously. LC Heating & Air provides same-day heat pump diagnosis and repair throughout Los Angeles County for all major brands.

I'm Leo, owner of LC Heating & Air. When your heat pump goes down in Whittier, you don't need a sales pitch; you need someone who understands the difference between a simple capacitor failure and a complex reversing valve issue. Because heat pumps handle both heating and cooling, they have extra parts—like defrost boards and reversing valves—that standard AC units don't have. If those parts fail, your system can get stuck in the wrong mode or stop working entirely.
My team and I focus on getting your system back to running right. We serve Whittier and the surrounding areas with honest, flat-rate estimates and a clear diagnostic process. We don't guess. We test your system in both heating and cooling modes to see exactly what is happening before we recommend a repair or a replacement.
Emergency calls are answered within 30 minutes — call (323) 970-3113 for dispatch.
Local HVAC considerations
Common Heat Pump Issues in Whittier
In Whittier, we see a lot of mixed-age housing stock. Whether you are in a classic single-family home or a newer multifamily building, the local climate and dust levels can take a toll on outdoor units. A common pattern I see is the 'stuck mode' issue. If your system is blowing cold air when you want heat, or vice versa, it is often a reversing valve failure. This valve is what switches the refrigerant flow, and when it sticks, the system can't switch modes properly.
Another issue is ice buildup. While a little frost is normal during a cold snap, if your outdoor unit is completely encased in ice, your defrost cycle isn't working. This usually points to a bad defrost board or a refrigerant leak. We check these components specifically because they are unique to heat pumps and often overlooked by general HVAC technicians.
HVAC Considerations for Whittier Homes
Whittier has a mix of older homes and newer remodels. This variety means we often find unique challenges with ductwork, electrical capacity, and equipment placement. When we arrive at your home, we don't just look at the unit; we look at the whole system. We check the airflow and the condition of your ducts because a high-efficiency heat pump won't work well if the ductwork is undersized or leaking.
Before we suggest any major work, we look at your electrical setup. Older homes sometimes need electrical upgrades to handle modern, high-efficiency heat pump systems. We want to make sure the equipment we install or repair is actually a good fit for your specific property.
Our Diagnostic Process
When I come out to your home, I follow a strict process. First, I test the system in both heating and cooling modes. I measure refrigerant pressures in both modes to see if the system is performing as it should. I also check the electrical components like the capacitor and contactor, which are common failure points.
Once I identify the fault, I explain it to you in plain English. I provide a written, flat-rate estimate before any work starts. You will know exactly what the repair costs and why it is needed. We don't start the repair until you have approved the estimate.
Repair or Replace?
This is the biggest question homeowners ask. My rule is simple: if the repair is reliable and the system has life left, we repair it. If the compressor is failing or the cost of the repair is a large percentage of the cost of a new system, we will tell you that it might be time to consider a replacement.
We also look at the age of the unit and the availability of parts. If your system is very old and uses an obsolete refrigerant, a repair might be a temporary fix. We will give you the honest truth so you can make an informed decision that makes sense for your budget.
Costs and Rebates
We believe in transparency. Our diagnostic fee is $125–$175. Common repairs like a capacitor replacement range from $150–$350, while a reversing valve replacement is typically $400–$650. If you do need a full system replacement, the cost ranges from $7,000 to $16,000 before any rebates.
There are programs like the TECH Clean CA rebate that can offer between $1,500 and $3,000 in savings after installation. We can help you understand if your project qualifies for these incentives.
Scheduling Service
We know that when your heat pump fails, you don't want to wait. We offer same-day service options and carry common parts like reversing valves and defrost boards on our trucks. When you call (323) 970-3113, we will get you on the schedule as quickly as we can.
We also provide guidance on emergency heat mode. If your system fails in the winter, we can walk you through how to use your backup heat strips safely until we can get out to your home to perform the repair.
Safety First
Your safety is our priority. We are fully licensed (CSLB #1073586) and insured. We make sure all electrical connections are secure and that the refrigerant levels are correct. We also check for proper airflow to prevent your system from overheating or icing up.
If your system is running on emergency heat, keep an eye on your electric bill. That mode is meant for short-term use only. If you find yourself using it for more than a few days, give us a call so we can get your primary heat pump back in service.

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