Heat Pump Repair & Service in Winnetka
LC Heating & Air provides heat pump repair in Winnetka — including heat pump services, heat pump not heating, heat pump replacement, energy efficient heat pump. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.

Heat pump systems are efficient, but they are complex. Because they handle both heating and cooling, a failure in one mode often points to a component that affects the entire system. At LC Heating & Air, I specialize in diagnosing these specific issues—like reversing valves, defrost boards, and refrigerant circuit faults—that other technicians sometimes miss.
I serve the Winnetka area with a focus on practical, long-term solutions. If your system is worth repairing, I will fix it right the first time. If it is time to consider a replacement, I will explain why based on the condition of your equipment and the specific needs of your home.
Emergency calls are answered within 30 minutes — call (323) 970-3113 for dispatch.

Common Heat Pump Issues in Winnetka
Winnetka’s climate puts a unique strain on heat pumps. With long summer run times, high attic temperatures, and 95-100 degree days, your system works hard. I frequently see issues with outdoor units clogged by dust or debris, which leads to overheating and premature component failure.
In the winter, I often get calls about units that are iced over or stuck in 'emergency heat' mode. These aren't always signs that you need a new system. Often, it is a faulty defrost board or a sensor issue that can be repaired once we get the unit cleaned and properly diagnosed.
Understanding Your Winnetka Home's System
Winnetka features a mix of mid-century ranch houses and larger remodels, many of which rely on attic-based duct systems. When I inspect your system, I look at the whole picture: the condition of your ductwork, the electrical capacity of your panel, and the clearance around your outdoor condenser.
If your ducts are leaking or undersized, even a brand-new heat pump will struggle to keep up. I don't just look at the 'box' outside; I look at how the entire system moves air through your home.
My Diagnostic Process
I don't believe in guessing. When I arrive, I test your heat pump in both heating and cooling modes. This is critical because a reversing valve failure might show up in one mode but not the other.
I measure refrigerant pressures, check your electrical components like capacitors and contactors, and inspect the defrost cycle. Once I have the data, I sit down with you to explain what I found and provide a flat-rate written estimate. You approve the cost before I turn a single wrench.
Repair vs. Replacement: An Honest Assessment
A lot of companies push for a full replacement the moment a system hits a certain age. I take a different approach. If a $400 repair can get you another few years of reliable service, I will tell you that. I am not here to sell you equipment you don't need.
However, if your system has a failing compressor, a leaking coil, or if the cost of repeated repairs is approaching the value of the unit, I will be upfront about it. I will explain the math so you can make an informed decision that fits your budget.
Costs and Rebates
I believe in transparent pricing. My diagnostic fee is $125–$175, which covers the time it takes to properly identify the root cause of your system's failure. For repairs, you can expect to pay between $200 and $650 for common components like capacitors, defrost boards, or reversing valves.
If we do determine that a new system is the best path forward, there are programs like the TECH Clean CA rebate that can help offset the cost by $1,500 to $3,000. I will help you understand if your project qualifies.
Scheduling Service in Winnetka
I know your time is valuable. When you call (323) 970-3113, you are reaching a local contractor, not a call center. I prioritize same-day service for heat pump failures because I know how uncomfortable it is to go without heating or cooling in our valley climate.
Please ensure there is clear access to your attic and outdoor unit before I arrive. If your unit is tucked away in a tight side yard or a difficult-to-reach attic, let me know when you book so I can bring the right tools.
Mistakes to Avoid
The biggest mistake I see is homeowners pouring water on an iced-over outdoor unit or trying to chip the ice away. This almost always damages the aluminum fins and can lead to a much more expensive repair. If your unit is iced over, turn it off and call me.
Another mistake is ignoring the 'AUX HEAT' or 'EM HEAT' light on your thermostat. If that light is on during a mild day, your heat pump is likely failing, and you are paying a premium on your electric bill to run the backup strips. Don't wait for the bill to arrive to find out there is a problem.
Health and Safety
Your safety is my priority. A properly functioning HVAC system is essential for indoor air quality and temperature control. I ensure all electrical connections are secure and that your system is operating within safe pressure limits.
As a licensed C-20 HVAC contractor (CSLB #1073586), I follow all safety protocols to protect your home and your family. If I find a safety hazard, I will show it to you and explain exactly why it needs to be addressed.
Is It Time for a Repair or Replacement?
This is the most common question I get at the kitchen table. If your heat pump is relatively new and just needs a capacitor or a defrost board, the choice is easy: repair it. These are standard maintenance items that keep your system running.
However, if your system is over 12-15 years old and the repair involves a major component like a compressor or a reversing valve, it is worth looking at the cost of a new, high-efficiency system. I will provide you with the facts so you can decide what makes the most sense for your home and your wallet.

What Winnetka customers say about heat pump repair
Verified reviews from homeowners in Winnetka and nearby neighborhoods who used our heat pump repair service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Called on a Saturday because AC was blowing warm air. LC answered, sent someone the same afternoon. They found and fixed a refrigerant leak. Professional and reasonably priced.”
“Woke up to no AC at 6am. LC was at my door by 9am. Frozen evaporator coil — they explained exactly why it happened (dirty filter + low airflow) and fixed it same visit. Very professional.”
