LC Heating & Air provides duct cleaning in Pacific Palisades — including air duct cleaning, duct repair service, duct sealing, HVAC ductwork. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.

If you live in Pacific Palisades, you know that our coastal climate can be tricky. Between the marine-layer humidity and the salt air, your HVAC system works hard to keep your home comfortable. Often, the problem isn't just the unit itself—it's the ductwork. If your system is running but certain rooms never seem to get comfortable, or your energy bills are higher than they should be, leaky ducts are usually the culprit.
At LC Heating & Air, I focus on the practical side of HVAC. I don't believe in pushing for a full system replacement if a targeted repair will solve the issue. My goal is to provide honest, clear diagnostics so you can make an informed decision about your home's comfort. Whether it's a disconnected flex duct in the attic or a need for comprehensive sealing, I'll show you exactly what's happening and what we can do to fix it.

Local HVAC considerations
Common Duct Issues in Pacific Palisades Homes
In our area, I frequently see ductwork that has been compromised by the environment or poor installation. Coastal moisture and salt air can accelerate the degradation of older duct materials, while the tight spaces in many of our local homes often lead to crushed flex duct runs. When ducts are crushed or disconnected, the airflow that should be cooling your living room ends up trapped in your attic or wall cavities.
I also see a lot of 'leaky boots'—the connection points where the duct meets the register. These are common spots for air to escape. Because Pacific Palisades homes often have unique layouts, these leaks can cause significant comfort swings between rooms. If you notice whistling sounds or excessive dust buildup near your registers, that's a clear sign your system is pulling in air from places it shouldn't, like a dusty attic.
Understanding Your Home's Ductwork
Pacific Palisades has a mix of older beach properties and renovated homes. In older houses, we often find original sheet metal ducts that have lost their seal over time, or newer flex duct that wasn't installed with enough support, leading to sagging and kinks. In renovated homes, sometimes the ductwork wasn't resized to match the new, high-efficiency equipment, which creates backpressure and reduces overall system life.
My diagnostic process starts with looking at the whole picture. I check the return sizing and the condition of the insulation. If your ducts are leaking, your HVAC system has to work significantly harder to reach the temperature you set on your thermostat. This extra runtime wears down your compressor and blower motor much faster than necessary.
How I Diagnose Duct Leaks
I don't guess when it comes to your home's comfort. My diagnostic process is straightforward: I measure the airflow at your registers and compare it to what your system is actually producing. I use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air you are losing.
This test gives us a number. It's not just me saying, 'your ducts are leaky.' It's measurable proof. Once I have those numbers, I can show you exactly where the leaks are and explain the most cost-effective way to fix them. You'll receive a written estimate before any work begins, so you know exactly what you're paying for.
Repair or Replace: Making the Right Choice
A common question I get is, 'Leo, should I just replace the whole system?' My answer is always the same: if the system is worth repairing, I will tell you. If the pattern of damage points to replacement, I will explain why. If your ducts are in decent shape but have a few major leaks, sealing them is almost always the better financial move.
However, if the ductwork is severely deteriorated, undersized, or made of outdated materials that are falling apart, patching it up is just a temporary fix. In those cases, I'll be honest about the long-term value of a proper replacement versus a band-aid repair. I want you to have a system that actually works for your home, not just a quick fix that leads to another service call next season.
What to Expect with Duct Repair Costs
Duct repair costs in Los Angeles vary based on the complexity of the job. A simple, targeted repair to a disconnected section might cost between $200 and $600. If we are doing a comprehensive sealing of your system, you're looking at a range of $800 to $2,000. For hard-to-reach leaks, we offer Aeroseal, which typically runs between $1,500 and $3,000 for a standard home.
I provide a written estimate after my initial inspection. My goal is to ensure the investment makes sense for your home. We don't use high-pressure sales tactics; we provide the facts and let you decide what fits your budget and your comfort needs.
Scheduling and Access in Pacific Palisades
Living in the Palisades means dealing with specific access challenges, whether it's roof access for condensers or navigating tight attic spaces. When I schedule your service, I account for these factors. I make sure we have the right equipment and enough time to do the job properly without rushing.
I am a local contractor, not a big franchise. When you call LC Heating & Air at (323) 970-3113, you're getting a professional who knows the local housing stock. I prioritize clear communication and showing up on time, because I know your time is valuable.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to fix duct leaks with standard duct tape. It doesn't hold up, especially in the heat of an attic. You need professional-grade mastic or foil tape designed for HVAC systems. Another mistake is ignoring the return side of the system. If your return ducts are leaking, you're pulling in attic air, which is full of dust and insulation fibers. This ruins your indoor air quality and makes your filters clog up in record time.
Don't assume that a 'cheap' repair is a good one. If the technician doesn't perform a post-repair test to verify the improvement, you have no way of knowing if the work actually solved the problem.
Health, Safety, and Air Quality
Duct leaks aren't just about comfort; they're about the air you breathe. When your supply ducts leak, you're losing conditioned air. When your return ducts leak, you're pulling in unfiltered air from your attic. This can introduce mold spores, dust, and insulation particles into your living space. Sealing your ducts is one of the most effective ways to improve your home's indoor air quality.
As a licensed contractor (CSLB #1073586), I take safety seriously. I ensure all repairs meet current standards, and I'm always happy to explain how our work keeps your home's air cleaner and your equipment running safely.
Is Duct Repair Right for You?
If you're tired of uneven temperatures and high energy bills, duct repair is often the most effective solution. It's a targeted improvement that addresses the root cause of the airflow issues rather than just treating the symptoms.
If you're ready to see if your ducts are the problem, give me a call at (323) 970-3113. We'll schedule a time to come out, inspect your system, and give you an honest, written assessment. No sales pitch, just the facts.

What Pacific Palisades customers say about duct repair
Verified reviews from homeowners in Pacific Palisades and nearby neighborhoods who used our duct repair service.
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
“We converted our garage into an ADU and needed HVAC. LC installed a Mitsubishi single-zone mini split — permits, electrical, everything. The unit is so quiet you can barely hear it running. Our tenant loves it.”
“Got a 3-zone Daikin system for our craftsman home — bedrooms upstairs, living room downstairs. Each room has its own temperature control and the monthly electric bill is actually lower than our old window units combined.”
