I'm Leo, owner of LC Heating & Air. I’ve spent enough time in Duarte attics and crawlspaces to know that a cooling system here has to work harder than in most places. Between the long summer run times and the intense heat that builds up in our local roof spaces, your AC is under constant pressure. When it stops cooling, you don't need a sales pitch—you need a clear answer on what’s broken and whether it’s worth fixing.
At LC Heating & Air, we don't believe in guessing. We show up, inspect the system, and give you a written estimate before we touch anything. We serve Duarte with the same standard I’d use for my own home: honest diagnostics, quality parts, and a focus on making sure your system actually moves air the way it should.

Common Cooling Issues in Duarte
Duarte homes, especially the mid-century ranch styles and larger remodels, often deal with specific airflow challenges. Because of our 95-100 degree days, if your ductwork isn't sized correctly or if your attic insulation is struggling, your AC will run constantly without ever actually cooling the house. We see a lot of systems that are 'working' but failing to move air effectively because of leaky connections or clogged evaporator coils.
Dust is another major factor here. It builds up on outdoor condenser coils, forcing the compressor to work harder and increasing your electric bill. We also see frequent issues with capacitors and contactors—the electrical parts that kick your system into gear. These are common, fixable problems, and we keep the parts on our trucks to handle them in one visit.

Repair or Replace: Making the Right Call
This is the most important conversation we have at the kitchen table. If your system is 10-12 years old and needs a minor repair like a capacitor or a drain flush, it’s usually worth fixing. But if the compressor is failing, or if the refrigerant system has a major leak in an old R-22 unit, the math changes. I’ll tell you straight: if a repair is just a band-aid on a system that’s on its last legs, I’ll recommend replacement.
We look at the whole picture—the condition of your ducts, the age of the equipment, and your monthly energy costs. If a new, high-efficiency SEER2 system will pay for itself in energy savings over a few years, we’ll show you the numbers so you can make an informed decision. We aren't here to sell you a new unit if your current one has plenty of life left.

What Duarte customers say about central ac service
Verified reviews from homeowners in Duarte and nearby neighborhoods who used our central ac service service.
“AC wasn't cooling to setpoint even though it was running all day. LC found the condenser coils were completely clogged with cottonwood. Cleaned them on the spot and the system cooled my house 12 degrees in an hour.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“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.”
