I'm Leo, owner of LC Heating & Air. If you're living in Playa Vista, you know our coastal climate brings unique challenges. Between the marine-layer humidity and the salt air, your home's HVAC system works hard. One of the most common issues I see in our local housing stock is leaky ductwork. When your ducts leak, you're paying to condition your attic or wall cavities instead of your living room.
Duct sealing is one of the most practical ways to improve your home's efficiency. By addressing leaks, we ensure that the air your system works to cool or heat actually reaches the rooms where you spend your time. Whether you're in a modern condo or an older beach property, sealing those gaps can make a noticeable difference in your energy bills and overall comfort.

Local HVAC considerations
Why Duct Sealing Matters in Playa Vista
In Playa Vista, we deal with a mix of modern planned communities and older coastal homes. A major issue here is duct leakage. When conditioned air leaks into attics, crawl spaces, or wall cavities, your system has to run longer to compensate for the lost air. This is particularly problematic in our climate, where humidity and salt air can accelerate the degradation of duct materials.
I often find that homeowners assume their system is failing when, in reality, the equipment is fine but the ductwork is leaking. If you notice uneven temperatures between rooms or your energy bills seem high for the size of your home, it's often a sign that your ducts need attention. We focus on identifying these leaks early to prevent unnecessary strain on your HVAC equipment.
Understanding Your Home's Ductwork
Playa Vista's housing stock ranges from newer, high-efficiency condos to older beach-style properties. Each type presents different challenges. In newer homes, we often see issues with poorly sealed connections or crushed flex ducts. In older properties, the ductwork may have simply degraded over time due to the coastal environment.
My diagnostic process starts by looking at the whole system. We check return sizing, duct leakage, and insulation levels. We don't just look for a quick fix; we look at how your ductwork interacts with the rest of your home's structure. If your system is worth repairing, I'll tell you. If the pattern of damage points to replacement, I'll explain exactly why so you can make an informed decision.
Our Diagnostic Approach
Before we touch a single duct, we perform a duct blaster test. This is the only way to quantify exactly how much air you're losing. We measure the leakage as a percentage of your system's total airflow. This gives us a clear baseline to work from.
Once we have the numbers, we decide on the best approach. Sometimes, manual mastic sealing is the right choice for accessible joints. Other times, we use Aeroseal to seal leaks from the inside out. After we finish, we re-run the duct blaster test to verify the results. You get the before and after numbers in writing, so you know exactly what you paid for.
Repair or Replace?
A common question I get is whether to repair existing ducts or replace them entirely. If your ducts are structurally sound but have leaky joints, sealing is usually the best path. It's cost-effective and provides a permanent fix.
However, if the ductwork is severely crushed, heavily contaminated, or falling apart, sealing won't solve the underlying problem. In those cases, I'll be honest with you about the need for replacement. My goal is to provide a solution that fits your property, not to push a generic service that won't last.
What to Expect Regarding Costs
Duct sealing costs vary based on the size of your home and the accessibility of the ducts. Manual mastic sealing typically ranges from $400 to $1,200, while Aeroseal internal sealing for a single-story home generally falls between $1,500 and $3,000. These prices include the diagnostic testing required to ensure the job is done right.
We believe in transparency. We provide a written estimate after our initial inspection, so you know exactly what the costs are before we start. We don't use high-pressure sales tactics; we provide the facts so you can decide what makes sense for your budget and your home.
Planning Your Service
In Playa Vista, we have to plan for specific access issues, such as roof access for condensers or routing drains to handle our damp coastal conditions. When we schedule your service, we take these factors into account to ensure the work is done safely and correctly.
Most residential duct sealing projects can be completed in a single day. If we use the Aeroseal process, we recommend that you vacate the home for about 60 to 90 minutes during the injection phase, though the process is safe and non-toxic. We'll coordinate with you to make the process as convenient as possible.
Common Mistakes to Avoid
One of the biggest mistakes I see is homeowners using standard silver 'duct tape' to fix leaks. That tape dries out and fails in just a few years. We use professional-grade mastic, which remains pliable and adheres permanently to the ductwork.
Another mistake is skipping the duct blaster test. Without testing, you have no way of knowing if the sealing actually worked or if you're still losing air. We always perform before and after testing to ensure the job meets California Title 24 standards and provides the energy savings you expect.
Health and Safety Considerations
Your indoor air quality is a priority. Leaky ducts don't just waste energy; they can pull dust, insulation particles, or moisture from attics and crawl spaces into your living areas. Sealing your ducts helps prevent these contaminants from entering your airstream.
When we use Aeroseal, we use a vinyl acetate polymer that is non-toxic and safe—it's the same material used in chewing gum. We always ensure the system is clean before sealing, and the sealant stays on the duct walls, not in the air you breathe. We take the safety of your home environment seriously.
Is Duct Sealing Right for You?
If your HVAC system is running constantly but your home still feels unevenly heated or cooled, duct sealing is often the missing piece. It's a high-ROI improvement that can reduce your energy usage by 15–25% if your ducts are significantly leaky.
If you're planning an HVAC replacement, I highly recommend testing your ducts first. It's much easier to address duct issues while we're already working on the system. Give LC Heating & Air a call at (323) 970-3113, and let's take a look at your system together.
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 Playa Vista customers say about duct sealing
Verified reviews from homeowners in Playa Vista 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.”
