I'm Leo, owner of LC Heating & Air. If you're dealing with rooms that never seem to get cool enough in the summer or warm enough in the winter, the problem often isn't your HVAC unit itself—it's the ductwork delivering that air. In Westlake Village, where our hillside homes and custom layouts often mean complex duct runs, even small leaks can cause major comfort issues.
My goal is to give you a clear, honest assessment of your system. I don't believe in pushing for a full replacement if a targeted repair will get your home comfortable again.

Local HVAC considerations
Common Duct Issues in Westlake Village
Westlake Village properties often feature custom designs and hillside construction that create unique challenges for ductwork. We frequently find crushed flex duct in tight attic spaces, disconnected joints caused by house settling, and leaky boots that allow conditioned air to escape into attics or wall cavities.
Because of the local climate and terrain, your HVAC system is working hard to combat heat gain. When ducts leak, you aren't just losing air; you're pulling in hot, dusty attic air through return leaks. This makes your system run longer, drives up your energy bills, and puts unnecessary strain on your blower motor and compressor.
Why Your Home's Layout Matters
Whether you live in a sprawling estate or a custom hillside home, the way your ducts are routed is critical. Many homes in this area have long duct runs that are susceptible to insulation damage or sagging over time. If the ductwork isn't properly supported or sealed, the air loses its temperature before it even reaches the register.
We pay close attention to these structural details. We check for proper register balance and ensure that your system isn't fighting against the natural heat gain of your specific property. A well-sealed duct system ensures that the air your equipment works to condition actually ends up in the rooms where you spend your time.
Our Diagnostic Process
I don't guess when it comes to your home's comfort. We start by measuring airflow at your registers to see which rooms are underperforming. From there, we perform a duct pressurization test—also known as a duct blaster test—to quantify exactly how much air is leaking out of the system.
Once we have the data, we inspect the accessible ductwork to pinpoint the source of the leaks. We look for torn inner liners, failed mastic at the plenums, and disconnected sections. You'll get a clear explanation of what we found and a written plan for the repair.
Repair vs. Replacement: Making the Right Call
One of the most common questions I get is, 'Leo, should I just replace the whole system?' My answer is always the same: if the equipment is in good shape and the ductwork can be sealed effectively, a repair is often the best path forward. We don't recommend replacing functional equipment just because of a few leaky joints.
However, if we find that the ductwork is severely undersized, collapsed, or deteriorated beyond the point of reliable repair, we will tell you straight. We want your system to last, and sometimes a targeted replacement of a specific duct run is the most cost-effective way to restore comfort without the expense of a full system overhaul.
Understanding Repair Costs
Duct repair costs vary based on the complexity of the job and the accessibility of the ducts. Simple reconnections or sealing a few joints are straightforward, while extensive sealing or replacing damaged sections in tight attics takes more time and labor.
We provide a written estimate before any work begins. Our pricing reflects the time required to access your specific mechanical areas and the materials needed to ensure the seal holds. We focus on providing value by fixing the root cause of the leak so you aren't paying for the same repair twice.
Access and Scheduling
Westlake Village homes often have tight-access mechanical areas and challenging attic spaces. We plan our work around these constraints, ensuring we have the right tools and access points to do the job properly without damaging your property.
We know your time is valuable. We coordinate our visits to minimize disruption to your day and ensure that we have enough time to complete the diagnostic and the repair correctly. If you have specific access concerns, let us know when you call, and we'll plan accordingly.
Common Duct Repair Mistakes
The biggest mistake I see is using the wrong materials. Duct tape, for instance, doesn't hold up in the temperature fluctuations of an attic. We use professional-grade mastic and specialized foil tape that is designed to stay sealed for years.
Another common issue is DIYers attempting to seal ducts without testing. If you seal one leak but ignore a larger one elsewhere, the system pressure can actually increase, causing new leaks to form. We always verify our work with post-repair testing to make sure the airflow is actually improved.
Health, Safety, and Air Quality
Leaky ducts aren't just an efficiency problem; they're an air quality issue. When your return ducts leak in an attic, they pull in insulation fibers, dust, and other particles that you then breathe in. Sealing these leaks keeps your indoor air cleaner.
We also check for proper combustion safety if your furnace is located in an area with ductwork. Ensuring your system is sealed and operating correctly is a key part of keeping your home environment safe and comfortable.
Is Your System Ready for Repair?
If you're noticing uneven temperatures or high energy bills, start by checking your filters and ensuring your registers aren't blocked by furniture. If those aren't the issue, it's time for a professional diagnostic.
Call LC Heating & Air at (323) 970-3113. We'll come out, inspect your system, and give you an honest assessment of whether a repair will solve your comfort issues. We're here to help you make an informed decision 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.
Cost factors we review before quoting
- • Accessibility of ductwork in attics or crawl spaces
- • Total amount of leakage identified during testing
- • Type of duct material (flex vs. sheet metal)
- • Scope of required repairs (patching vs. section replacement)

“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.”
