At LC Heating & Air, I focus on fixing the distribution issues that make your HVAC system work harder than it needs to. If your home in Valley Village has uneven temperatures or high energy bills, your ductwork is often the culprit.

I'm Leo, owner of LC Heating & Air. I’ve spent years crawling through Valley Village attics, and I can tell you that most comfort problems aren't caused by the AC unit itself, but by the ducts that carry the air. When your ducts leak, you’re paying to air-condition your attic instead of your living room.
My approach is simple: I don't guess. I use diagnostic tools to find exactly where your system is losing air. Whether it’s a disconnected flex duct in a tight crawl space or a series of leaks at the plenum, I’ll show you the problem, explain the fix, and give you a written estimate before we start any work.

Local HVAC considerations
Common Duct Issues in Valley Village
Valley Village homes, especially our mid-century ranch houses, often rely on attic-mounted duct systems. Over time, the heat in our attics—which can easily hit 100 degrees during the summer—breaks down the tape and mastic at the joints. I frequently see crushed flex duct caused by foot traffic in the attic, which chokes off airflow to specific rooms.
Another pattern I see is 'return leakage.' If your return ducts are leaking in the attic, they are pulling in hot, dusty air and insulation fibers directly into your system. This doesn't just hurt your efficiency; it makes your home dustier and forces your equipment to run longer cycles to compensate for the heat gain.
Understanding Your Home's Airflow
Your HVAC system is a closed loop. If you have a 3-ton unit but your ducts are only sized or sealed to handle 2 tons of air, you’re going to have issues. In many larger remodels I see in the area, the original ductwork wasn't upgraded to match the new, higher-capacity cooling systems.
When I inspect your system, I look at the whole picture: the return sizing, the condition of the duct boots, and how the air is actually reaching your registers. If the ductwork is undersized or poorly routed, no amount of repair will fix the comfort issues. I’ll be honest with you about whether a repair will solve the problem or if the duct system itself is the bottleneck.
My Diagnostic Process
I don't believe in guessing. When I arrive, I start by measuring the airflow at your registers. If one room is consistently hot, I check if the duct serving that room is blocked, crushed, or disconnected.
For a deeper look, I use duct pressurization testing. This tells me exactly how much air is escaping the system. Once I have the numbers, I can show you the difference between a minor repair—like sealing a few joints—and a more comprehensive fix. You get the facts, and you decide how you want to proceed.
Repair vs. Replacement: The Honest Truth
A lot of companies will push for a full duct replacement the moment they see a tear. That’s not always necessary. If your ductwork is structurally sound but just has some leaks at the joints, sealing it with mastic is often the best path forward.
However, if the ducts are original, falling apart, or severely undersized, patching them is just throwing good money after bad. If I see that the duct material is deteriorated beyond the point of a reliable seal, I’ll tell you. My goal is to provide a solution that lasts, not a quick fix that fails in six months.
What to Expect with Costs
I provide written estimates for every job. The cost depends on access and the scope of the work. Simple repairs to accessible sections are straightforward, while sealing a whole system or using Aeroseal for hidden leaks involves more labor and equipment.
We keep our pricing transparent. You’ll know exactly what you’re paying for before we start. We focus on high-return improvements that actually make a difference in your comfort and your monthly utility bills.
Access and Scheduling in Valley Village
Working in Valley Village homes means dealing with specific access challenges. Whether it’s a tight attic crawl space or ductwork buried behind drywall, I plan for these factors before I arrive. I’ll coordinate with you to ensure we have the access we need to do the job right.
I know your time is valuable. I aim for efficient, clean work that minimizes disruption to your home. We respect your property and leave the workspace as clean as we found it.
Common Duct Repair Mistakes
The biggest mistake I see is using standard duct tape for repairs. It dries out and fails within a season, especially in our hot attics. I use professional-grade mastic and foil tape designed to hold up under temperature fluctuations.
Another mistake is ignoring the return side of the system. People focus on the supply registers, but if your return ducts are leaking, you’re pulling in dirty attic air. A proper repair addresses both sides of the system to ensure your air quality and efficiency are both improved.
Health, Safety, and Air Quality
Your ducts are the lungs of your home. If they are leaking in the attic, they are pulling in dust, insulation fibers, and whatever else is up there. This is a major factor in indoor air quality.
By sealing your ducts, we prevent that attic air from entering your living space. This is especially important for households with allergies or respiratory sensitivities. I take this seriously because I know the difference it makes in your home environment.
Making the Right Choice for Your Home
When you're deciding whether to repair or replace, look at the age and condition of your ducts. If they are relatively new but have a few leaks, a professional sealing job is usually the best value. If they are old, brittle, or undersized, it might be time to consider a system-wide upgrade.
I’m here to give you the information you need to make that call. I’ll show you what I find in the attic, explain the impact on your comfort, and give you a straight answer on what makes the most sense for your house.
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 the ductwork in your attic or crawl space.
- • The total amount of leakage detected by our duct blaster test.
- • The type of duct material (flex duct vs. sheet metal).
- • Whether the repair requires simple sealing or 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.”
