I am Leo, owner of LC Heating & Air. I have spent years working on the unique homes here in Hidden Hills. Because of the hillside terrain and the way many of these custom estates are built, I see a lot of duct systems that have been compromised by poor access, shifting, or simple wear and tear over time.
When your ducts leak, your HVAC system works harder than it needs to, pushing air into your attic or crawl space instead of your living room. My goal is to provide a clear, honest assessment of your ductwork so you can decide if a repair will solve your comfort issues or if the system requires more significant attention.

Local HVAC considerations
Common Duct Issues in Hidden Hills
In Hidden Hills, the combination of hillside construction and tight-access mechanical areas often leads to specific duct problems. We frequently find flex duct that has been crushed during attic maintenance or disconnected at the joints due to the natural settling of older homes. When these ducts aren't sealed properly, you lose conditioned air before it ever reaches your vents.
Another issue I see often is related to the local climate. Because of the sun exposure and elevation changes across these properties, even a small leak in a supply run can make a room feel significantly hotter or colder than the rest of the house. We focus on identifying these specific leaks and providing a repair plan that makes sense for your home's layout.
Ductwork in Custom Estate Homes
Hidden Hills features a lot of custom estate lots and older custom homes. These properties often have complex duct runs that are difficult to reach. When we perform a diagnostic, we look at how your ductwork is routed through your specific floor plan. We don't just look for leaks; we look for design flaws like undersized returns or restricted airflow that might be causing your system to struggle.
Because of the way these homes are built, access is everything. We plan our service around the specific constraints of your attic or crawl space, ensuring we can reach the trouble spots without causing damage to your home.
Our Diagnostic Process
I don't believe in guessing. When I come out to your home, I start by measuring the airflow at your registers to see what is actually coming out of your vents. We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air is leaking out of your system.
This data allows me to show you exactly where the problems are. Once we have the numbers, I can explain whether a targeted repair will fix the issue or if we are looking at a larger problem that requires a different approach.
Repair vs. Replacement
A common question I get is whether it is worth repairing old ducts or if they should be replaced entirely. If the ductwork is structurally sound but has a few disconnected joints or small leaks, a repair is usually the right choice. We use mastic and foil tape to seal these leaks effectively.
However, if the ducts are severely crushed, moldy, or made of outdated materials that are falling apart, repair might be a temporary fix for a permanent problem. If the system is worth repairing, I will tell you. If the pattern points to replacement, I will explain why so you can make an informed decision.
Understanding Costs
I provide written estimates before we start any work. The cost of duct repair varies based on the accessibility of your ducts and the extent of the damage. A simple reconnection of a flex duct is a different job than sealing a whole-house system with Aeroseal.
My goal is to provide value. By sealing your ducts, you are often reducing the runtime of your HVAC equipment, which lowers your energy bills and reduces wear on your system. We focus on repairs that offer the best return on your investment.
Access and Scheduling
Working in Hidden Hills requires planning. Between the gated access and the specific terrain of these properties, we make sure we have the right equipment and enough time to do the job right. We respect your property and your time, and we always coordinate our arrival to minimize disruption to your day.
Whether it is a tight attic space or a complex line-set route, we account for these factors before we start. We want to get the job done correctly the first time so you don't have to worry about callbacks.
Common Mistakes to Avoid
The biggest mistake I see is homeowners trying to patch ducts with standard duct tape. It doesn't hold up to the temperature changes in an attic and will fail quickly. Another mistake is ignoring the return side of the system. If your return ducts are leaking, you are pulling attic air—and all the dust and insulation fibers that come with it—directly into your home.
Professional sealing requires the right materials, like mastic, and the right approach to ensure the system is actually airtight. Don't waste time on temporary fixes that don't address the root cause of your airflow issues.
Health and Safety
Your indoor air quality is directly tied to your ductwork. When ducts leak in an attic, they act like a vacuum, pulling in dust, insulation, and potential mold spores. Sealing these leaks isn't just about comfort; it's about keeping the air in your home clean.
We also check for proper system operation to ensure that your HVAC equipment is running safely. If we find issues that could impact your health or the safety of your home, we will bring them to your attention immediately.
Is Your System Ready for Repair?
If you are tired of hot spots in your home or your energy bills are higher than they should be, it is time to look at your ducts. We provide a professional diagnostic to see if your system is a candidate for repair or if you are better off with a different solution.
Call LC Heating & Air at (323) 970-3113. We will come out, inspect your system, and give you a straightforward, honest assessment of what your home needs.
How the visit works
We perform a thorough diagnostic, including airflow measurements and duct pressurization testing to find exactly where your system is losing air.
We provide a written repair plan that outlines the work needed and the cost, so you know exactly what to expect before we start.
We perform the repairs using professional-grade materials like mastic, or we use Aeroseal for hard-to-reach leaks.
We re-test your system to verify the improvement in airflow and ensure the leaks are sealed.

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