I'm Leo, owner of LC Heating & Air. I've spent enough time in Beverly Glen attics to know that the biggest problem with your HVAC system often isn't the unit itself, but the ductwork delivering the air. If your home has rooms that never seem to get comfortable, or if your energy bills are climbing despite the system running fine, it's time to look at the ducts.
Most duct systems lose 20–30% of their conditioned air through leaks. In our climate, that means you are paying to cool your attic instead of your living room. At LC Heating & Air, we don't just guess; we use diagnostic testing to find exactly where your system is losing air and provide a clear, honest plan to fix it.

Local HVAC considerations
Common Duct Issues in Beverly Glen
Beverly Glen homes face specific challenges. Between the marine-layer humidity and the way homes are tucked into the Santa Monica Mountains, we see a lot of ductwork that has suffered from moisture exposure or physical damage. Common issues include disconnected flex duct sections at joints, crushed ducts from attic foot traffic, and failed mastic at supply plenums.
Because of the coastal air and temperature swings, we also see insulation breakdown on older ducts. When the inner liner of a flex duct tears, you lose efficiency and start pulling in attic dust, which ends up in your living space. We focus on identifying these specific points of failure to restore proper airflow to every room in your home.
Ductwork in Coastal Canyon Homes
Beverly Glen has a mix of older beach-style properties and renovated homes. Older homes often have undersized or deteriorating sheet metal ducts, while newer renovations might have flex duct that wasn't installed with enough support, leading to kinks and airflow restrictions.
We understand the layout of these homes. Whether your ducts are tucked into tight crawl spaces or running through complex attic configurations, we plan our access carefully. We prioritize fixing the airflow bottlenecks that cause comfort swings, ensuring your system isn't working harder than it needs to.
Our Diagnostic Process
We don't start by selling you a new system. We start by measuring what your current system is actually doing. We perform a duct pressurization test—also known as a duct blaster test—to quantify exactly how much air is leaking out of your system.
We also measure airflow at your registers. If one room is 10 degrees hotter than the rest of the house, the data will show us if it's a duct leak, a restriction, or a sizing issue. We give you a written estimate based on these findings so you know exactly what we're fixing and why.
Repair vs. Replacement
A common question I get is, 'Leo, should I just replace the whole system?' The answer depends on the condition of the ducts. If the ductwork is structurally sound but leaking at the joints, a professional repair is the best value. We can seal those leaks and get your system running efficiently again.
However, if the ducts are severely crushed, undersized, or the material has deteriorated to the point where it's falling apart, patching it is just a band-aid. If the repair cost approaches the cost of a proper replacement, I will tell you that directly. My goal is to provide a fix that lasts, not one that requires a callback in six months.
Understanding Your Costs
Duct repair costs vary based on the accessibility of your attic or crawl space and the extent of the damage. A simple reconnection of a flex duct is a quick fix, while comprehensive sealing or Aeroseal application for inaccessible leaks requires more time and specialized equipment.
We provide a transparent, written estimate before we start. You won't find hidden fees here. We focus on the work that provides the highest return on investment for your comfort and energy bills.
Access and Scheduling
Working in Beverly Glen means planning for the terrain and the specific layout of your home. We coordinate with you to ensure we have the necessary access to your attic or crawl space. We respect your home and your time, keeping the workspace clean and finishing the job as efficiently as possible.
If you have an urgent comfort issue, we offer same-day service options when available. Our goal is to get your system back to peak performance without disrupting your day.
Common Mistakes to Avoid
One of the biggest mistakes I see is homeowners trying to seal ducts with standard duct tape. It doesn't hold up to the temperature changes in an attic and will fail quickly. We use professional-grade mastic and foil tape designed for HVAC systems.
Another mistake is ignoring the return side of the system. If your return ducts are leaking, you're pulling in hot, dusty attic air directly into your system, which ruins your indoor air quality and puts extra strain on your blower motor. We check both the supply and return sides to ensure the whole loop is tight.
Health and Safety
Your health is tied to your ductwork. When ducts leak in an attic, they act like a vacuum, pulling in insulation fibers, dust, and potential mold spores. By sealing those leaks, we aren't just saving you money on energy; we are keeping that attic air out of your living space.
We are a CSLB-licensed contractor (CSLB #1073586). We follow safety protocols to ensure that our repairs don't interfere with your home's combustion safety or ventilation requirements. You can trust that the work is done to code.
Is Duct Repair Right for You?
If your energy bills are high and your home has 'hot spots' or 'cold spots,' duct repair is often the most cost-effective solution. It improves comfort immediately and reduces the wear and tear on your HVAC equipment by allowing it to run shorter cycles.
If you're unsure, give us a call at (323) 970-3113. We can come out, perform a diagnostic, and show you exactly what's happening with your system. We'll give you the facts, and you can decide what makes sense for your home.
How the visit works
We measure airflow at registers, inspect accessible ductwork, and perform duct pressurization testing to quantify leakage.
We identify the specific leaks and damage and present a repair scope with written pricing before any work begins.
We access damaged sections and seal with mastic, reconnect disconnected flex duct, and repair torn inner liners.
We re-test duct leakage after repair and measure airflow at registers to confirm improvement.

What Beverly Glen customers say about duct repair
Verified reviews from homeowners in Beverly Glen and nearby neighborhoods who used our duct repair 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.”
