Professional duct sealing to stop energy loss and improve whole-home comfort. We provide duct blaster testing and proven sealing methods for Beverly Crest homes.
I'm Leo, owner of LC Heating & Air. If your HVAC system is running constantly but your home still feels uneven, the issue is often hiding in your ductwork. In Beverly Crest, we see many homes where conditioned air is leaking into attics or wall cavities instead of reaching your living rooms. You are paying to cool or heat spaces you don't occupy, which drives up energy bills and puts unnecessary strain on your equipment.
Duct sealing is one of the most practical ways to improve your home's efficiency. Whether we use manual mastic sealing for accessible joints or Aeroseal for internal, hard-to-reach leaks, our goal is to ensure your system delivers air where it belongs. We are a locally owned contractor, not a franchise, and we focus on honest diagnostics before recommending any work.
Local HVAC considerations
Marine-layer humidity and salt air can accelerate corrosion in HVAC components and duct connections.
We account for roof access and attic space constraints common in Santa Monica Mountain homes.
We ensure all work meets California Title 24 standards for duct leakage testing.
Why Beverly Crest Homes Need Duct Sealing
Beverly Crest homes often face unique challenges due to our coastal climate and housing stock. Marine-layer humidity and salt-air exposure can degrade duct materials over time, leading to gaps at joints and connections. When these seals fail, your system loses pressure, and your HVAC unit has to work much harder to maintain the temperature.
We often see duct leakage in older beach properties and even in some newer renovations where the ductwork wasn't properly balanced. If you notice unusual dust accumulation near your registers or rooms that never seem to reach the right temperature, it is a sign that your ducts are leaking. We check these patterns during our initial diagnostic to see if sealing will solve the comfort issue or if the ductwork has structural damage that requires a different approach.
Repair vs. Replace: Making the Right Call
I get asked all the time if a system should be repaired or replaced. My answer is always the same: it depends on the condition of the equipment and the ductwork. If your ducts are structurally sound but have leaks at the joints, sealing is a high-value repair that pays for itself through energy savings. We will perform a duct blaster test to quantify the leakage, which gives us the hard data needed to make an informed decision.
If the ductwork is severely damaged, crushed, or made of outdated materials that are falling apart, sealing might just be a temporary fix. In those cases, I will be honest with you about the costs versus the long-term benefits of replacement. We don't push for replacement unless it is truly the most practical and cost-effective path for your home.
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.
Cost factors we review before quoting
- • Total square footage of the duct system
- • Accessibility of the ductwork in attics or crawl spaces
- • The severity of the leakage found during the initial test
- • Choice between manual mastic sealing versus Aeroseal internal sealing

What Beverly Crest customers say about duct sealing
Verified reviews from homeowners in Beverly Crest 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.”
