At LC Heating & Air, I see a lot of homes in the Lakeside Golf Club area where the HVAC system is working hard, but the comfort isn't reaching the rooms. Often, the issue isn't the furnace or the air conditioner itself—it's the ductwork. If your ducts are leaking, you are essentially paying to air condition your attic or wall cavities instead of your living space.
My name is Leo, and I run LC Heating & Air. We focus on practical, honest solutions. If your system is leaking, I will show you the data from our duct blaster test so you can make an informed decision about whether sealing is the right move for your home. We are licensed (CSLB #1073586) and dedicated to getting your system running as efficiently as it was designed to.

Why Duct Sealing Matters in Lakeside Golf Club
In our local climate, we deal with long summer run times and significant valley heat. When your ductwork has leaks, that hot attic air is pulled into your system, or your cooled air is pushed out into unconditioned spaces. This forces your equipment to run longer and harder than it should, which leads to premature wear and higher energy bills.
Many of the larger custom homes and estates in this area have multi-zone systems that are complex. If the ductwork isn't sealed properly, the pressure imbalances can cause dust to be pulled into the house from attics or wall cavities. We focus on identifying these leaks to ensure your system is actually delivering the air where you need it.
Understanding Your Home's Ductwork
Lakeside Golf Club features a unique mix of historic and custom-built homes. Older sheet metal ducts often develop leaks at the joints over time, while newer flex duct systems can suffer from crushed runs or poor connections. We don't believe in a one-size-fits-all approach.
Whether your home has accessible attic ductwork or hidden, inaccessible runs, we have the tools to address the leaks. We look at the entire system, including plenums and register connections, to ensure the air you pay to condition stays inside your home.
Our Diagnostic Approach
We start with 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 rate. This gives us a baseline and helps us determine if manual sealing or Aeroseal is the better path for your specific home.
After we perform the sealing, we run the test again. You get the before-and-after numbers in writing. I believe in showing you the proof so you know exactly what you are paying for and the results you are getting.
Repair vs. Replacement Decisions
A common question I get is whether to seal old ducts or just replace them. If your ducts are structurally sound but just leaky at the joints, sealing is a very cost-effective way to improve performance. However, if the ductwork is deteriorated, collapsed, or undersized for your equipment, sealing won't fix the underlying problem.
I will always be honest about what makes sense. If I see that your duct system is beyond repair, I will tell you. If a simple seal will get you another ten years of comfort, I will recommend that. My goal is to provide a solution that fits your property, not to sell you work you don't need.
Cost and Value
Duct sealing is one of the best investments you can make for energy efficiency. By sealing 20–30% leakage, you can often reduce your HVAC energy use by 15–25%. In the Los Angeles market, that adds up quickly.
We offer manual mastic sealing for accessible areas and Aeroseal for inaccessible systems. Costs vary based on the size of your home and the complexity of the duct layout. We provide a written estimate after our initial diagnostic so you know the cost before we start.
Access and Professional Service
I understand that properties in Lakeside Golf Club require a high level of discretion and coordination. We respect your privacy and ensure our service is executed cleanly and professionally. We coordinate property access to fit your schedule and ensure our technicians are respectful of your home and time.
We are a local contractor, not a big corporate franchise. When you call (323) 970-3113, you are working with a team that knows the local housing stock and the specific challenges of our climate.
Common Duct Mistakes to Avoid
The biggest mistake I see is using standard silver 'duct tape' to seal connections. It dries out, cracks, and fails within a few years. We use professional-grade mastic and foil-backed HVAC tape that is designed to last for the life of the system.
Another mistake is ignoring duct leakage during an HVAC equipment replacement. If you install a high-efficiency furnace or AC unit but leave the leaky ducts in place, you are wasting the potential of that new equipment. Always test your ducts when you upgrade your system.
Health and Safety
Your indoor air quality is a priority. Leaky ducts don't just lose conditioned air; they can pull in dust, insulation fibers, and pollutants from your attic or crawl space. Sealing these leaks keeps that debris out of your living area.
When we use the Aeroseal process, we ensure it is done safely. The material is non-toxic and tested for indoor air quality. We take all necessary precautions to ensure your home remains a safe and comfortable environment throughout the entire process.
Is Duct Sealing Right for You?
If your energy bills are high, your home has uneven temperatures, or you notice dust buildup near your registers, it is time to look at your ducts. Sealing is a permanent improvement that pays for itself through lower utility bills and increased comfort.
Call LC Heating & Air at (323) 970-3113 to schedule a diagnostic. We will test your system, show you the results, and give you an honest recommendation on whether sealing is the right move 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
- • System size and number of zones
- • Accessibility of ductwork in attics or crawl spaces
- • Type of duct material (flex vs. sheet metal)
- • Severity of existing leakage
- • Choice between manual mastic sealing or Aeroseal

What Lakeside Golf Club customers say about duct sealing
Verified reviews from homeowners in Lakeside Golf Club and nearby neighborhoods who used our duct sealing service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Called on a Saturday because AC was blowing warm air. LC answered, sent someone the same afternoon. They found and fixed a refrigerant leak. Professional and reasonably priced.”
“Woke up to no AC at 6am. LC was at my door by 9am. Frozen evaporator coil — they explained exactly why it happened (dirty filter + low airflow) and fixed it same visit. Very professional.”
