LC Heating & Air provides expert heat pump diagnosis and repair in Mid-City. We specialize in reversing valve issues, defrost board failures, and refrigerant circuit diagnostics for all major brands.
When your heat pump stops working in Mid-City, you aren't just losing comfort—you're losing both your heating and cooling capabilities. Because heat pumps use the same components to handle both seasons, a failure in one mode often points to a specific mechanical or electrical issue that needs a precise fix. I'm Leo, and at LC Heating & Air, I focus on getting your system back to running correctly without unnecessary sales pressure.
Whether you're dealing with a unit that won't switch from cooling to heating, or you've noticed ice buildup on your outdoor coil, we handle it. We serve the diverse housing stock of Mid-City, from older single-family homes to modern remodels, ensuring your equipment is diagnosed based on its actual condition and performance.

Heat pump diagnosis and repair
Common Heat Pump Issues in Mid-City
In our local climate, we see a lot of heat pumps struggling with the basics. A very common issue is the reversing valve getting stuck. This valve is what tells your system to switch between heating and cooling. If it sticks, you might find your house blowing cold air when you’ve set the thermostat to heat. We see this often in systems that haven't been maintained, as dust and debris can affect the solenoid operation.
Another pattern we see is ice buildup. While a little frost is normal during a cold snap, a completely iced-over outdoor unit usually means the defrost board has failed or there is a refrigerant leak. In Mid-City's mixed-age homes, we also frequently find that older ductwork or poor airflow is masking a perfectly good heat pump, making it work harder than it should. We check the whole system—not just the box outside—to make sure you aren't paying for a repair that won't solve the root cause.
Mid-City Housing and HVAC Performance
Mid-City is a mix of everything—older single-family homes, duplexes, and newer multifamily developments. This variety means there is no 'one-size-fits-all' repair. In older homes, we often find that electrical panels or duct sizes weren't originally designed for modern, high-efficiency heat pumps. When we perform a repair, we look at how the equipment is placed and whether the existing infrastructure is actually supporting the system.
If you're in a remodel, you might have a newer system that requires specific diagnostic tools for inverter-driven compressors. We don't guess. We use the same technical standards for a 20-year-old unit as we do for a brand-new installation, ensuring that the repair is compatible with your home's specific electrical and airflow constraints.
Our Diagnostic Approach
When I arrive at your home, I don't start by talking about new equipment. I start by testing. We run the system in both heating and cooling modes. This is critical because a heat pump that works in cooling but fails in heating is telling us exactly where the problem lies—usually in the reversing valve or the defrost circuit.
We measure refrigerant pressures and check the electrical components like the contactor and capacitor. If the system is clicking but not starting, it’s often a simple capacitor issue. If it’s running but not heating, we look deeper. Once we identify the fault, I provide a written, flat-rate estimate. You’ll know exactly what the repair costs before we turn a single wrench.
Repair or Replace: An Honest Assessment
Homeowners often ask me if they should just replace an old unit. My answer is always the same: if the repair is reliable and the system has life left, fix it. However, if the compressor is failing or the cost of the repair is a significant percentage of a new system, I’ll tell you that, too. We look at the age of the unit, the cost of the repair, and the overall efficiency of your current setup.
If you do need a replacement, we’ll talk about the real costs and the available rebates, like the TECH Clean CA program, which can help offset the price. We don't push for replacement unless it's the most practical, long-term decision for your home.
Understanding Repair Costs
We believe in transparency. A standard diagnostic visit is $125–$175. Most common repairs, like replacing a capacitor or a defrost board, fall between $200 and $650. If you are looking at a full system replacement, costs typically range from $7,000 to $16,000 before any applicable rebates.
Keep in mind that rebates like the TECH Clean CA program can provide significant savings—often between $1,500 and $3,000—but these are applied after the installation. We help you understand these factors so you can make an informed decision based on your budget and your home's needs.
Scheduling Your Service
We know that when your heat pump goes down, you don't want to wait. We offer same-day service options and carry common parts—like reversing valves, defrost boards, and capacitors—on our trucks. This allows us to complete many repairs in a single visit.
When we schedule your call, we consider access to your equipment. Whether your unit is in a tight attic, a crawl space, or tucked into a side yard, we make sure we have the right tools and enough time to do the job right. We respect your property and your time.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to 'fix' an iced-over unit by chipping away at the ice. Please, don't do this. You can easily puncture the aluminum fins or damage the refrigerant lines, turning a simple defrost issue into a very expensive repair. Another mistake is ignoring the 'Emergency Heat' light on your thermostat. If that light is on, your heat pump isn't doing the work—your electric heat strips are. This will lead to a massive spike in your electric bill.
Finally, don't ignore strange noises. A clicking sound that repeats is a warning sign. If you catch these issues early, the repair is usually straightforward. If you wait until the system completely fails, you might be looking at a much larger, more expensive problem.
Safety First
Your safety is our priority. We are a CSLB-licensed contractor (License #1073586), which means we follow all safety codes for electrical and refrigerant handling. We don't cut corners on wiring or system pressure testing. When we work on your heat pump, we ensure that the electrical connections are tight and that the system is operating within safe pressure limits.
If you suspect a refrigerant leak or an electrical fault, turn the system off at the thermostat and give us a call. We’ll get out there to assess the situation safely.
Making the Right Choice
Choosing between a repair and a replacement is a big decision. At LC Heating & Air, we provide you with all the facts so you can choose what's best for your home. If your system is relatively new and the repair is a simple component failure, we’ll fix it and get you back to comfort.
If your system is aging, inefficient, or requires a repair that costs nearly as much as a new unit, we will be honest about that. We want you to have a system that works reliably for years to come, not one that keeps you calling for service every few months.
How the visit works
We test the system in both heating and cooling modes, measure refrigerant pressures in both modes, and identify the specific fault.
We test capacitors, contactors, reversing valve, defrost board, and refrigerant circuit components as indicated by the diagnostic.
We explain the fault and provide a flat repair price. You approve; we repair.
We complete the repair and test both heating and cooling operation before leaving.
