Heat pump systems are complex because they handle both heating and cooling. When they fail, you need a technician who understands the reversing valve, defrost cycles, and refrigerant circuits. I am Leo, owner of LC Heating & Air, and I provide honest, practical repairs for South Pasadena homeowners.

Common Heat Pump Issues in South Pasadena
In our local climate, I see a few recurring patterns with heat pumps. The most common is the 'stuck' reversing valve. This is the part that tells your system to switch from cooling to heating. If it gets stuck, you might find your system blowing cold air when you want heat, or vice versa. It is a specific repair, but it is one I handle regularly.
I also see issues with defrost boards. Because our winters can get chilly, your outdoor unit needs to melt frost off its coils. If that board fails, your unit can end up encased in ice. Before you assume the worst, have a pro check the board and the refrigerant levels. Often, it is a component-level repair rather than a full system replacement.
Working with South Pasadena's Historic Homes
South Pasadena's housing stock is beautiful, but it is not always built for modern HVAC. Many homes here were built long before central air was standard. When I work in a historic home, I am careful about how we route lines and where we place equipment. We look for ways to use existing chases or closets to keep the installation clean and minimally invasive.
I also account for the local environment. Our tree canopy provides great shade, which changes how your home holds heat compared to a house in the middle of a concrete-heavy neighborhood. I factor that into my diagnostics and recommendations so you don't end up with an oversized, inefficient system.
My Diagnostic Process
When I arrive at your home, I don't just guess. I test the system in both heating and cooling modes. I measure refrigerant pressures and check the electrical components like the contactor and capacitor. This tells me exactly what is failing.
I will explain the problem to you in plain English. If it is a simple capacitor or a faulty defrost sensor, I will tell you. If the compressor is failing, I will show you the readings so you understand why a repair might not be the best long-term investment. You get a written estimate before I start any work.
Repair or Replace?
This is the most important conversation I have with homeowners. A repair should be a solid fix that gives you more years of service. If I am looking at a 15-year-old unit with a failed compressor and a leaking coil, I am going to tell you that a repair is just throwing good money after bad. That is not how I do business.
However, if your system is relatively young and just needs a new reversing valve or a control board, I will fix it. My goal is to help you get the most out of the equipment you already have, provided it is safe and reliable to do so.
Costs and Rebates
I believe in transparency. My diagnostic fee is $125–$175. Common repairs like a capacitor or a defrost board usually range from $200 to $650. If you do need a full system replacement, those range from $7,000 to $16,000 depending on the equipment.
There are programs like the TECH Clean CA rebate that can offer $1,500 to $3,000 off a new heat pump installation. I can help you understand if your project qualifies for these, but I will never use rebates as a pressure tactic to sell you a system you don't need.
Scheduling and Access
I serve the 91030 area from my local service hub. I know that when your heat pump goes out, you don't want to wait days for a callback. I offer same-day service options and I make sure to check your electrical capacity and duct condition before we finalize any plans. I want to make sure the job is done right the first time so you don't have to call me back for the same issue.
You can reach me at (323) 970-3113 to discuss what is happening with your system. If I am on a job, I will get back to you as soon as I am finished.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to chip ice off their outdoor coils with a screwdriver or pouring hot water on them. Please don't do that. You can damage the aluminum fins and cause a much more expensive repair. If your unit is iced over, turn it off and call me.
Another mistake is ignoring the 'Emergency Heat' light on your thermostat. If that light is on all the time, your heat pump is likely not working, and you are running on expensive electric backup strips. It will show up on your next utility bill, and it is a sign that you need a professional to look at the system.
Health and Safety
Your HVAC system is part of your home's health. Poorly maintained systems can circulate dust or struggle to manage humidity, which is especially important in our older homes. I check for proper airflow and ensure your system is operating safely. If I see a safety issue with your electrical or gas connections, I will point it out immediately. My license (CSLB #1073586) means I am held to high standards, and I take that responsibility seriously.
Making the Right Choice for Your Home
When you are deciding whether to fix your heat pump or replace it, look at the frequency of your repairs. If you are calling for service every season, the system is telling you it is tired. If it is a one-time failure on a well-maintained unit, a repair is usually the smart move.
I am here to give you the facts so you can make the decision that fits your life. I don't work on commission, and I don't have a sales quota. My goal is to provide honest service that makes you want to call me again when you need help.

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