When your heat pump stops working, it’s not just an inconvenience—it’s a disruption to your home's climate control. Because heat pumps handle both heating and cooling, a failure often means you lose both functions at once. I’m Leo, owner of LC Heating & Air, and I’ve spent years working on the specific challenges we see in Mar Vista homes, from attic-mounted duct systems to the high-load demands of our local climate.
My approach is simple: I show up, I diagnose the system, and I tell you exactly what’s going on. Whether it’s a faulty capacitor, a stuck reversing valve, or a defrost board issue, I’ll explain the repair options clearly. If the system is worth saving, we’ll fix it. If the repair costs don't make sense, I’ll be the first to tell you so you can make an informed decision about replacement.
Emergency calls are answered within 30 minutes — call (323) 970-3113 for dispatch.

Common Heat Pump Issues in Mar Vista
In Mar Vista, our long summer run times and the occasional cold snap put unique stress on heat pumps. I frequently see systems struggling with ice buildup on the outdoor unit. While a little frost is normal, if your unit is encased in ice, it’s a sign that the defrost board or the refrigerant levels aren't right. We don't just clear the ice; we find out why it’s happening.
Another pattern I see involves the reversing valve. If your system is blowing cold air when you need heat, or vice versa, the valve is likely stuck. This is a specialized repair that requires precise refrigerant pressure testing. We carry the parts to handle these repairs on-site, ensuring your system is tested in both heating and cooling modes before we call the job finished.
Understanding Your Mar Vista Home's System
Mar Vista has a mix of housing, from mid-century ranch houses to larger, modern remodels. Many of these homes rely on attic-based duct systems. When we service your heat pump, we aren't just looking at the outdoor condenser. We check the airflow, the duct condition, and the electrical capacity of your home to ensure the system is actually capable of handling the load.
If you have an older system, we look at how it integrates with your current thermostat. Sometimes, what looks like a major failure is actually a configuration issue where the system is stuck in 'emergency heat' mode, which can lead to surprisingly high electric bills. We make sure your system is set up to run efficiently.
Our Diagnostic Process
I don't believe in guessing. When I arrive at your home, 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. This tells me exactly what the system is doing—or failing to do.
Once I identify the fault, I provide a written, flat-rate estimate. You’ll know the cost before I turn a single wrench. After the repair, we run the system through its paces again to confirm that the heat pump is cycling correctly and that the defrost cycle is functioning as it should.
Repair vs. Replacement: Making the Right Call
Deciding whether to fix an old heat pump or replace it is a big decision. If the repair is a simple component failure—like a capacitor or a contactor—it’s usually a straightforward fix. However, if the compressor is failing or the system has a major refrigerant leak in an inaccessible coil, the repair costs can start to approach the value of the unit.
I’ll give you the honest truth: if I think a repair is just a 'band-aid' that will lead to more problems in six months, I’ll tell you. If we do decide on a replacement, we can discuss current options, including high-efficiency systems and available rebates like the TECH Clean CA program, which can help offset the cost of a new installation.
Understanding Costs and Rebates
We keep our pricing transparent. A standard diagnostic visit is $125–$175. Most common component repairs, such as replacing a capacitor or a defrost board, fall between $200 and $650. We don't hide fees or push for unnecessary work.
For those looking at a full system replacement, the investment typically ranges from $7,000 to $16,000 before rebates. We can help you navigate the paperwork for the TECH Clean CA rebate, which can provide significant savings. We want the math to make sense for your household budget.
Scheduling Service in Mar Vista
I know your time is valuable. When you call LC Heating & Air, we work to get you on the schedule quickly. Because we are a local shop, we understand the logistics of Mar Vista neighborhoods—from attic access points to the clearance needed around your outdoor condenser.
When you book an appointment, let us know if you have specific access issues, like a tight attic crawl space or a locked gate. Being prepared helps us get the job done right the first time, so you aren't left waiting for a second visit.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to 'fix' an iced-over unit by pouring hot water on it or chipping away at the ice. Please don't do this. You can easily damage the aluminum fins on the coil, which are very delicate. If your unit is frozen, turn it off and give us a call.
Another mistake is ignoring the 'Emergency Heat' light on your thermostat. If that light stays on, your system is running on expensive backup strips instead of the heat pump. It might feel like it's working, but your electric bill will tell a different story at the end of the month.
Health and Safety First
Your safety is the priority. A malfunctioning heat pump can lead to electrical issues or poor indoor air quality if the ductwork is compromised. We check for proper electrical connections and ensure that the system is operating safely within the manufacturer's specifications.
If you ever smell burning plastic or hear loud, grinding noises from your unit, turn it off at the breaker and call us immediately. It’s better to be safe and have us take a look than to risk further damage to your home’s electrical system.
Is It Time to Call for Help?
If your heat pump is clicking, failing to switch modes, or running on emergency heat, it’s time for a professional look. You don't have to guess what's wrong or worry about high-pressure sales tactics.
At LC Heating & Air, we provide the facts. We’ll tell you what’s broken, what it costs to fix, and whether it makes sense to keep the unit running. Give us a call at (323) 970-3113 to schedule your diagnostic.
