Fix leaky and damaged ducts to improve comfort, lower energy bills, and stop wasting conditioned air in your attic.
I'm Leo, owner of LC Heating & Air. If you live in the Hollywood Hills, you know that our homes are unique. Between the steep slopes, the canyon heat, and the way these houses are tucked into the landscape, your HVAC system has a tough job. Often, the reason a room is always too hot or the AC bill is higher than it should be isn't the equipment itself—it's the ductwork.
Most homeowners never see their ducts, but they are the veins of your home. If they are leaking, crushed, or disconnected, your furnace or AC is working twice as hard to do half the job. At LC Heating & Air, we specialize in finding those hidden leaks and fixing them the right way. We serve the Hollywood Hills area with honest, plain-spoken service to make sure your home is actually comfortable.

Hillside mechanical access and airflow
Common Duct Issues in Hollywood Hills Homes
In our neighborhood, we deal with specific challenges. Many homes here have tight-access mechanical areas, and the way ducts are routed through attics or under floors can be complicated by the slope of the lot. We frequently find crushed flex duct caused by foot traffic in tight attic spaces, or sections that have simply come apart at the joints due to the shifting nature of hillside properties.
Another issue I see often is return duct leakage. If your return ducts are leaking in a hot attic, they are pulling in that super-heated air and mixing it with your conditioned air before it even reaches your living space. This makes your system run longer than it needs to, which wears out your equipment faster. We focus on identifying these specific points of failure rather than just guessing.
Understanding Your Home's Mechanical Layout
Hollywood Hills homes range from older custom builds to modern hillside estates. The mechanical layout in these houses is rarely standard. You might have long duct runs to reach rooms on different levels, or registers that were poorly placed during a past remodel. When we inspect your system, we look at how the ductwork interacts with your home's specific architecture.
If your ducts are undersized or poorly routed, no amount of repair will fix a fundamental airflow problem. We provide an honest assessment of whether your current duct layout is capable of delivering the comfort you expect, or if we are just putting a band-aid on a system that needs a different approach.
How We Diagnose Duct Problems
I don't believe in guessing. When I come out to your home, we start with a proper diagnostic. We measure the airflow at your registers to see what is actually coming out of the vents. We also perform a duct pressurization test—also known as a duct blaster test—to quantify exactly how much air you are losing.
This test gives us a number. It tells us if your leakage is 5% or 30%. Once we have that data, I can show you exactly where the leaks are and explain what it will take to fix them. You get a written estimate before we touch anything, so you can decide if the repair makes sense for your budget.
Repair vs. Replacement: Making the Right Call
A lot of companies will try to sell you a whole new system when a simple duct repair would solve your comfort issues. My job is to tell you the truth. If your ducts are in decent shape but have a few disconnected joints or small tears, we can seal them up and get you back to comfort for a fraction of the cost of a new system.
However, if the ductwork is falling apart, undersized, or made of outdated materials that are beyond saving, I will tell you that, too. If the system is worth repairing, we will fix it. If the pattern points to replacement, we will explain why so you can make an informed decision based on your long-term goals for the property.
What Affects the Cost of Duct Repair
The cost of duct repair in the Hollywood Hills is largely driven by accessibility. Because so many of our homes have tight crawl spaces or difficult attic access, the labor involved in reaching the ducts is often the biggest factor. A simple repair in an open attic is much faster than navigating a cramped, sloped space.
We offer a range of services from targeted sealing of specific leaks to full-system Aeroseal treatments for hard-to-reach areas. We provide clear, written pricing so you know exactly what you are paying for before we start. We don't use high-pressure sales tactics; we just provide the service your home needs.
Scheduling Service in the Hills
I know that living in the Hollywood Hills means dealing with narrow roads and tricky access. When you call LC Heating & Air at (323) 970-3113, we take that into account. We plan our service calls to ensure we have the right equipment and enough time to do the job right, even if the access is difficult.
We are a local, licensed contractor (CSLB #1073586), not a big corporate franchise. When you schedule with us, you are getting a technician who understands the local geography and the specific challenges of our hillside homes.
Mistakes to Avoid with Ductwork
The biggest mistake I see is homeowners trying to patch ducts with standard duct tape. It doesn't hold up to the temperature changes in an attic. We use professional-grade mastic and specialized foil tape that is designed to last. Another mistake is ignoring the 'whistling' sounds coming from your walls; that is almost always a sign of a significant leak that is costing you money every single day.
Don't assume that high energy bills are just a part of living in a big house. If your system is running constantly but your rooms aren't comfortable, there is a reason. Let us take a look before you spend money on a new system you might not need.
Air Quality and Your Ducts
Your ducts don't just move air; they move the air you breathe. If your return ducts are leaking in an attic, they are pulling in insulation fibers, dust, and whatever else is up there. That air then gets pushed directly into your living room. Sealing your ducts isn't just about efficiency; it's about keeping your indoor air cleaner.
We take safety seriously. We ensure that our repairs don't interfere with your system's safety components, like the heat exchanger or the blower motor. We want your system to run safely and efficiently for years to come.
Is It Time to Call a Pro?
If you are noticing rooms that are always too hot, high energy bills, or excess dust in your home, it is time to have your ducts checked. You don't need to guess if your system is failing.
Call LC Heating & Air at (323) 970-3113. We will come out, perform a diagnostic, and give you an honest answer about whether a repair will solve your problem or if it is time to look at other options. We are here to help, not to sell you things you don't need.
How the visit works
We measure airflow at registers, inspect accessible ductwork, and perform duct pressurization testing to quantify leakage.
We identify the specific leaks and damage and present a repair scope with written pricing before any work begins.
We access damaged sections and seal with mastic, reconnect disconnected flex duct, and repair torn inner liners.
We re-test duct leakage after repair and measure airflow at registers to confirm improvement.
Cost factors we review before quoting
- • Accessibility of ductwork in attics or crawl spaces
- • Total amount of leakage identified during testing
- • Type of repair required (manual sealing vs. Aeroseal)
- • Size and complexity of the home's duct network

What Hollywood Hills customers say about duct repair
Verified reviews from homeowners in Hollywood Hills 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.”
