If you live in Oakmont Country Club, you know that our hillside homes often come with unique challenges. Between the slope orientation and the way these homes were built, your HVAC system is working harder than it should if your ducts are leaking. I’m Leo, owner of LC Heating & Air, and I see it all the time: homeowners paying to cool their attic or crawl space instead of their living room.
Duct sealing is one of the most practical ways to improve your home's efficiency. When we seal your ducts, we aren't just patching holes; we are ensuring that the air your system works to condition actually reaches your rooms. Whether you have an older estate or a custom hillside property, we use the right tools—from manual mastic to Aeroseal—to get the job done right.

Why Duct Leaks Are Common in Oakmont
In our hillside neighborhood, many homes have ductwork running through tight, inaccessible crawl spaces or attics that get extremely hot. Over time, the materials used to connect these ducts—like old tape or failing mastic—dry out and crack. Because of the way these homes are built, it's common for conditioned air to escape into these unconditioned spaces.
When your ducts leak, your HVAC system has to run longer to reach the temperature you set on your thermostat. This doesn't just drive up your utility bills; it puts unnecessary strain on your equipment, which can lead to premature failure. If you notice dust building up around your registers or certain rooms that never seem to get as cool as the rest of the house, it’s a sign that your duct system needs a professional look.
Understanding Your Home's Ductwork
Oakmont Country Club features a mix of historic estates and custom properties, each with different duct configurations. Some use rigid sheet metal, while others rely on flexible ducting that can be easily crushed or kinked during past repairs or home modifications. When we inspect your system, we look at the entire path the air takes.
We don't believe in one-size-fits-all solutions. If your ducts are accessible, we use high-quality mastic to seal joints and connections. If the leaks are hidden deep within the walls or in areas we can't reach by hand, we use Aeroseal to seal them from the inside. We tailor our approach to your home's specific construction.
Our Diagnostic Process
Before we touch a single joint, we perform a duct blaster test. This is the only way to know exactly how much air you are losing. We pressurize your duct system and measure the leakage as a percentage of your total airflow. This gives us a clear baseline.
Once we have the numbers, we walk you through what we found. We’ll show you where the leaks are and explain whether manual sealing or Aeroseal is the better path for your specific system. We provide written estimates so you know exactly what you’re paying for before we start.
Repairing vs. Replacing Your Ducts
A common question I get is, 'Leo, should I just replace the whole system?' The answer depends on the condition of the ducts. If your ductwork is structurally sound but just leaky at the joints, sealing is a permanent, cost-effective solution. It’s often the best way to extend the life of your existing equipment.
However, if the ducts are crushed, undersized, or made of materials that are falling apart, sealing won't solve the underlying problem. In those cases, we will be honest with you and recommend replacement. We want you to have a system that works, not just a temporary patch.
What to Expect with Costs
We believe in transparency. Duct sealing costs vary based on the size of your home and the accessibility of your ducts. Manual sealing typically ranges from $400 to $1,200, while Aeroseal for a single-story home usually falls between $1,500 and $3,000. These prices include the diagnostic testing and the verification test at the end.
When you consider that sealing can reduce your HVAC energy use by 15–25%, the work often pays for itself through lower monthly utility bills. We provide a clear, written estimate after our initial inspection so there are no surprises.
Access and Scheduling in Oakmont
Working in Oakmont Country Club means we are used to navigating narrow driveways and hillside access. We plan our equipment placement carefully to ensure we can get the job done efficiently without disrupting your day. Most residential duct sealing projects are completed in a single day.
We respect your time and your property. Whether it's a simple manual seal or the Aeroseal process, we make sure the work area is clean and that you understand how to operate your system once we are finished.
Health and Safety Considerations
Your indoor air quality is important. When we seal your ducts, we are preventing dust, insulation particles, and other debris from being pulled into your airstream. The materials we use, including the Aeroseal polymer, are safe and non-toxic.
For the Aeroseal process, we do recommend that you step out of the home for about 60 to 90 minutes while we inject the sealant. It’s a standard precaution, and you can return as soon as the process is finished and the system has run for a few minutes to clear the air.

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
