If your HVAC system is running constantly but your living room still feels stuffy or unevenly cooled, the problem might not be the unit itself. Often, the issue is the ductwork. In Playa del Rey, we see many homes where conditioned air is leaking into attics, wall cavities, or crawl spaces before it ever reaches your vents. You are essentially paying to air condition your insulation.
At LC Heating & Air, I focus on practical, long-term solutions. Whether we are using manual mastic sealing for accessible joints or Aeroseal for hidden leaks, my goal is to make sure your system delivers air where you actually need it. I am Leo, and I believe in giving you an honest assessment of your ductwork so you can make an informed decision about your home's efficiency.

Local HVAC considerations
Duct Issues in Playa del Rey Homes
Playa del Rey's coastal climate brings marine-layer humidity and salt-air exposure, which can be tough on HVAC components. Beyond the equipment, this moisture and salt can affect the integrity of ductwork over time, especially in older beach properties. We frequently find that original flex duct or sheet metal systems have developed gaps at connections or tears in the insulation.
When ducts are not properly sealed, the salt air and humidity from outside can be pulled into the system through leaks, which doesn't just hurt efficiency—it can impact your indoor air quality. We focus on identifying these leakage points and ensuring your ductwork is properly sealed to withstand our specific coastal conditions.
Understanding Your Duct System
Playa del Rey has a mix of housing, from older beach cottages to renovated homes with modern high-efficiency systems. In older homes, we often find ductwork that was never properly sealed during original construction. Even in newer renovations, if the ductwork wasn't tested during installation, you might be losing 20% or more of your airflow.
My diagnostic process starts with a duct blaster test. This allows me to quantify exactly how much air you are losing. I don't guess; I use the numbers to show you where the leaks are and whether a repair or a more comprehensive sealing process is the right move for your specific home.
Our Diagnostic Approach
Before I touch a single piece of ductwork, I perform a pre-sealing duct leakage test. This is the only way to know if your system is actually leaking and by how much. I look for crushed flex runs, poor insulation, and disconnected plenums that are common in local attics.
Once I have the data, I explain the options. If the leaks are in accessible areas, we use mastic and foil tape. If the leaks are deep inside the walls or in inaccessible ceiling cavities, I will explain how Aeroseal can seal those gaps from the inside. We finish every job with a post-sealing test to prove the improvement.
Repair or Replace?
A common question I get is whether a duct system is worth sealing or if it should be replaced entirely. If the ducts are structurally sound but just leaky at the joints, sealing is almost always the better, more cost-effective choice. It saves you money and improves comfort immediately.
However, if the ductwork is crushed, heavily contaminated, or undersized for your current equipment, sealing won't fix the underlying airflow restriction. In those cases, I will be upfront with you that replacement is the smarter long-term investment. I am not here to sell you a service you don't need; I am here to make sure your system works correctly.
What to Expect on Costs
I believe in transparency. Duct sealing costs vary based on the size of your home and the accessibility of the ducts. Manual sealing for accessible areas typically ranges from $400 to $1,200. For more complex, inaccessible systems, Aeroseal ranges from $1,500 to $3,000. These prices include the diagnostic testing required to verify the work.
Keep in mind that sealing your ducts is an investment that pays for itself. By reducing duct leakage, you can cut your HVAC energy use by 15–25%. At current electricity rates, many homeowners see the cost of the service paid back in energy savings within a couple of years.
Scheduling Your Service
Living in Playa del Rey means dealing with specific access challenges, such as roof access for condensers or tight crawl spaces. When we schedule your service, I account for these factors so we aren't surprised on the day of the job. Most residential duct sealing projects can be completed in a single day.
If you are planning an HVAC replacement, it is the perfect time to seal your ducts. In fact, California Title 24 often requires duct leakage testing when you replace your equipment. I can handle the testing and the sealing to ensure your new system is compliant and performing at its peak.
Common Duct Mistakes
One of the biggest mistakes I see is the use of standard silver 'duct tape' on HVAC systems. It dries out, cracks, and falls off within a few years. I only use professional-grade mastic and foil-backed tape that stays flexible and lasts for the life of the system.
Another mistake is ignoring the return side of the system. Many people focus only on the supply vents, but if your return ducts are leaky, you are pulling unconditioned air from the attic or walls into your system. We test the entire system, both supply and return, to ensure a complete seal.
Safety and Air Quality
Your health is the priority. When we use Aeroseal, the material is a non-toxic polymer similar to what is found in chewing gum. It is safe for your home, and we ensure the system is clean before and after the process. We also take care to ensure that your ductwork is properly sealed so that pollutants from attics or garages aren't being circulated into your living space.
If you have concerns about dust or allergens, sealing your ducts is a great first step. By closing the gaps where dust enters the system, you keep your air cleaner and your filters working more effectively.
Is Duct Sealing Right for You?
If you notice your energy bills are high for the size of your home, or if some rooms are always hotter or colder than others, it is time to look at your ducts. Duct sealing is one of the most effective ways to improve your home's performance without replacing your entire HVAC system.
Call LC Heating & Air at (323) 970-3113. I will come out, perform a diagnostic test, and give you a written estimate. We will look at the facts together, and I will tell you exactly what your system needs to run efficiently.
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 del Rey customers say about duct sealing
Verified reviews from homeowners in Playa del Rey 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.”
