I’m Leo, the owner of LC Heating & Air. When I walk into a home in the Brentwood Country Club area, I’m often looking at unique challenges. Between the hillside topography, the mix of custom estate homes, and the tight-access mechanical areas, your ductwork is doing a lot of heavy lifting. If your system is leaking, you aren't just losing money on your utility bill—you’re losing the comfort you’re paying for.
Duct sealing isn't about selling you a new system; it’s about making sure the one you have actually works. Whether we are using manual mastic sealing or the Aeroseal process, my goal is to ensure your conditioned air reaches your living spaces instead of escaping into your attic or wall cavities. We provide clear, honest assessments so you can decide what makes sense for your home.

Why Duct Sealing Matters in Brentwood Country Club
In this neighborhood, we see a lot of hillside homes and custom properties where the ductwork has been tucked into tight, hard-to-reach spaces. Over time, these ducts can develop leaks due to shifting, aging materials, or poor initial installation. When your ducts leak, your HVAC system has to run longer and harder to reach the temperature you set on your thermostat.
Because of the sun exposure and elevation changes common in our local hillside market, room-by-room comfort differences are a frequent complaint. If your ducts are leaking, the system can't properly balance the airflow, leaving some rooms too hot while others are too cold. Sealing these leaks is often the most effective way to address these comfort issues without needing a full system replacement.
Understanding Your Home's Ductwork
Brentwood Country Club features a wide variety of housing, from older custom homes to newer estate builds. Older homes often have sheet metal ductwork that has lost its seal over the decades, while newer properties might rely on flex duct that can be easily crushed or disconnected in tight attic spaces. We don't use a one-size-fits-all approach.
We look at the specific layout of your home. If your ductwork is accessible, we can often perform manual mastic sealing. If your ducts are buried in walls or inaccessible attic sections, we use the Aeroseal process to seal them from the inside out. We always start by assessing the condition of your specific system, because that detail matters—it changes the repair decision.
Our Diagnostic Process
We don't guess. We start with a duct blaster test to quantify exactly how much air you are losing. This gives us a baseline percentage of leakage. By knowing the numbers, we can show you exactly where the problem is and how much of an impact sealing will have on your system's efficiency.
After we perform the sealing work, we run the test again. This verification step ensures that the work was done correctly and that your system is now operating within the expected efficiency range. We provide you with the before-and-after documentation so you know exactly what you paid for.
Repair vs. Replacement: Making the Right Choice
A common question I get is whether it's worth sealing old ducts or if it's time to replace them. If your ductwork is structurally sound but just leaky at the joints, sealing is almost always the right move. It’s a permanent, cost-effective solution that can save you 15–25% on your HVAC energy use.
However, if the ducts are crushed, undersized, or made of materials that are falling apart, sealing might just be a band-aid. If the system is worth repairing, I will tell you. If the pattern points to replacement, I will explain why. My job is to give you the information you need to make a decision that makes sense for your home and your budget.
Investment and Value
Duct sealing is one of the highest-ROI improvements you can make. With LA electricity rates, the energy savings often pay for the service in under two years. We offer transparent pricing for our inspections and sealing services, and we always provide a written estimate before we start any work.
Because we are a local, licensed contractor (CSLB #1073586), we ensure all our work meets California Title 24 compliance. If you are doing this as part of a larger HVAC project, we make sure the documentation is ready for your permit requirements.
Access and Scheduling in the Hills
Working in the Brentwood Country Club area means we have to be mindful of your property. We plan our access around your home’s specific layout, whether that involves navigating narrow roads or working in tight attic spaces. We know your time is valuable, and we aim to complete most residential duct sealing projects in a single day.
If you have an upcoming HVAC replacement, let us know. Coordinating duct sealing with your equipment installation is often the most efficient way to handle both projects, ensuring your new system isn't wasting energy through leaky, old ducts.
Common Duct Sealing Mistakes to Avoid
The biggest mistake I see is the use of standard silver 'duct tape' on HVAC systems. It dries out, the adhesive fails, and within a few years, you're back to square one. We use professional-grade mastic and foil-backed HVAC tape that is designed to last for the life of the system.
Another mistake is skipping the testing phase. Without a duct blaster test, you have no way of knowing if the sealing actually worked or if the leaks were just hidden in a spot the technician couldn't reach. We believe in measuring the results so you don't have to guess.
Health and Safety
Your indoor air quality is a priority. When we seal your ducts, we aren't just stopping energy loss; we are also preventing your system from pulling in dust, insulation fibers, and debris from your attic or crawl spaces. This keeps your air cleaner and your system running more efficiently.
For our Aeroseal process, we use a non-toxic, vinyl acetate polymer that is safe for your home. It’s the same material used in common household items like chewing gum. We take every precaution to ensure the process is clean, safe, and effective for your family.
Is Duct Sealing Right for You?
If you notice your HVAC system runs constantly but your home still feels uneven, or if your energy bills seem high for the size of your home, it’s time to take a look at your ducts. We don't believe in high-pressure sales; we believe in showing you the data.
Call LC Heating & Air at (323) 970-3113. We’ll come out, inspect your system, and give you an honest answer about whether duct sealing will solve your comfort problems or if there’s a bigger issue at play. We’re here to help you get the most out of your home’s climate control.
How the visit works
We perform a duct blaster test to quantify existing leakage as a percentage of system airflow.
Based on leakage quantity, duct type, and accessibility, we recommend manual sealing, Aeroseal, or a combination.
We apply mastic to all accessible joints and plenums, or set up and run the Aeroseal process for internal sealing.
We re-run the duct blaster test and provide you with before/after leakage numbers as written documentation.

What Brentwood Country Club customers say about duct sealing
Verified reviews from homeowners in Brentwood Country Club and nearby neighborhoods who used our duct sealing 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.”
