Fix leaky and damaged ducts — better comfort, lower energy bills.
I'm Leo, owner of LC Heating & Air. If you're living in a home here in Beverlywood, you know that our hillside and canyon properties come with unique challenges. Whether you're in an original 1940s home or a newer custom build, the way your HVAC system moves air is just as important as the equipment itself. If your ducts are leaking, you're paying to cool your attic instead of your living room.
Duct repair isn't about selling you a new system; it's about making sure the air your furnace or AC produces actually makes it to your vents. I focus on practical, honest diagnostics to see if a repair will solve your comfort issues. If the system is worth repairing, I'll show you exactly where the leaks are and how we can fix them.

Common Duct Issues in Beverlywood Homes
In our neighborhood, we see a lot of specific duct problems. Because many of our homes are built on slopes or have tight-access mechanical areas, ductwork often gets crushed or disconnected during past renovations or attic work. We frequently find disconnected joints, torn flex duct liners, and failed mastic at supply plenums.
The climate here—with our sun exposure and elevation changes—means your HVAC system is already working hard. When ducts leak, that conditioned air escapes into hot attic spaces, forcing your system to run longer cycles. This leads to higher energy bills and uneven temperatures where some rooms are always too hot while others are freezing.
Why Your Home's Layout Matters
Beverlywood is a unique place to work. The 1940s housing stock often features custom layouts that weren't originally designed for modern high-efficiency HVAC systems. When we inspect your ducts, we look at how the home's architecture impacts airflow. Long duct runs to reach distant rooms or tight spaces under eaves can lead to airflow restrictions that simple repairs can often resolve.
We don't believe in one-size-fits-all solutions. We look at your specific home's duct routing and register balance to ensure that the air is distributed evenly throughout the house. If a room is consistently uncomfortable, it's usually a sign of a duct issue, not necessarily a failing AC unit.
Our Diagnostic Process
I don't guess when it comes to your home's comfort. We start by measuring airflow at your registers to see what's actually coming out of your vents. Then, we perform a duct pressurization test—a duct blaster test—to quantify exactly how much air is leaking out of your system.
This data gives us a clear picture. We'll show you the results so you can see the difference between a minor leak and a major distribution problem. Before we touch anything, we provide a written estimate so you know exactly what the repair entails and what it will cost.
Repair vs. Replacement: Making the Right Call
A lot of companies will push for a full duct replacement the moment they see a leak. That's not how I operate. If the ductwork is structurally sound but has a few disconnected joints or small tears, a targeted repair is often the best path forward. We use high-quality mastic and foil tape to seal those leaks properly.
However, if the ductwork is severely deteriorated, undersized for your equipment, or made of outdated materials that are falling apart, we will tell you honestly that replacement is the better long-term investment. My goal is to provide a solution that makes sense for your budget and your home's needs.
Understanding the Costs
Duct repair costs vary based on how accessible the ducts are. If we can reach the leaks easily in an open attic, the cost is lower. If we have to navigate tight crawl spaces or move insulation, the labor time increases. We provide transparent pricing for everything from simple inspections to comprehensive sealing.
We also offer Aeroseal for systems where manual repair isn't practical. This process seals leaks from the inside, which is incredibly effective for inaccessible duct runs. We'll discuss these options with you during our visit so you can choose the method that fits your situation.
Scheduling Service in Beverlywood
I know your time is valuable. Because we are based right here in Los Angeles, we understand the local traffic and the specific access needs of our neighborhood. Whether it's ladder access for attic work or navigating narrow roads, we plan our service calls to be efficient and respectful of your property.
When you call (323) 970-3113, you're talking to a local contractor, not a call center. We'll work with you to find a time that fits your schedule and make sure we have the right equipment on the truck before we head out to your home.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to use duct tape to seal leaks. Standard duct tape dries out and falls off within months in a hot attic. We use professional-grade mastic and mechanical fasteners that are designed to last. Another mistake is ignoring the 'whistling' sound from your vents—that's a clear sign of a significant leak that is costing you money every single day.
Don't assume that a dusty home is just a cleaning issue. If you see dust accumulating quickly around your supply registers, it's likely that your return ducts are pulling in dirty air from your attic. Fixing the leak stops the dust at the source.
Health and Safety Considerations
Your indoor air quality is tied directly to your ductwork. When return ducts leak in the attic, they pull in insulation fibers, dust, and potentially mold spores, which are then distributed throughout your home. Sealing these leaks isn't just about efficiency; it's about breathing cleaner air.
We take safety seriously. We ensure that all repairs are done to code and that your system's airflow is balanced correctly to prevent backdrafting or other safety issues. We are CSLB licensed (#1073586) and insured, so you can have peace of mind while we work in your home.
Is Duct Repair Right for You?
If you're noticing uneven temperatures, high energy bills, or excessive dust, it's time to take a look at your ducts. A professional diagnostic is the first step. We'll tell you exactly what's going on and whether a repair will solve the problem or if you're better off looking at other options.
At LC Heating & Air, I believe in being straightforward. I'll give you the facts, explain the repair process, and let you make the decision that's best for your home. Call us at (323) 970-3113 to get started.

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