If your home in Lake Balboa has rooms that never seem to get comfortable, or if your energy bills are higher than they should be, the problem might not be your AC unit itself—it might be the ductwork. Most homeowners don't realize that their ducts are hidden in attics and crawl spaces, often leaking conditioned air before it ever reaches the living room.
At LC Heating & Air, I believe in being straightforward about what your home needs. I’m Leo, and I’ve seen enough duct systems in the San Fernando Valley to know that a little bit of repair work can often do more for your comfort than a brand-new system. We focus on finding the specific leaks, measuring the airflow, and giving you a clear, honest assessment of whether a repair will solve your problem.

Common Duct Issues in Lake Balboa Homes
In Lake Balboa, our homes deal with long summer run times and intense attic heat. When your ductwork has leaks, your system is forced to pull in that hot, dusty attic air, which then gets pushed directly into your living space. We frequently find crushed flex ductwork caused by attic foot traffic, disconnected joints at the plenums, and torn insulation that allows conditioned air to escape into the rafters.
These issues are common in both our mid-century ranch houses and larger remodels. If you notice whistling sounds near your registers or if you find yourself dusting your home more often than usual, it is a strong sign that your ducts are compromised. We look for these specific patterns to ensure we aren't just patching a symptom, but actually fixing the distribution of air throughout your home.
Understanding Your Home's Airflow
Lake Balboa has a mix of housing styles, from classic mid-century homes to modern remodels. Many of these homes rely on attic-based duct systems that were installed decades ago. Over time, the materials used to seal these ducts—like old tape or mastic—can dry out and crack, leading to significant air loss.
When we inspect your system, we look at the entire path the air takes. We check the return sizing to make sure your system can breathe, and we inspect the supply runs to ensure the air is actually reaching the rooms that need it most. If your ductwork is undersized or poorly routed, no amount of repair will fix the comfort issues, and that is when we start the conversation about whether a larger modification or replacement is necessary.
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. If one room is getting 200 CFM and another is getting 50, we know exactly where to look. We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air is leaking out of your system.
This testing gives us a baseline. Once we know the extent of the leaks, we can provide a written estimate for the repair. We don't start any work until you understand what we found and why it matters. My goal is to give you the information you need to make the right decision for your home, whether that's a simple patch or a more involved repair.
Repair or Replace: Making the Right Call
This is the most important conversation we have. If your ducts are in decent shape but have a few disconnected sections or torn liners, a repair is usually the best path forward. It’s cost-effective and provides immediate comfort improvements.
However, if the ductwork is severely undersized, made of outdated materials that are falling apart, or if the layout is fundamentally flawed, patching it might be a waste of your money. If the system is worth repairing, I will tell you. If the pattern points to replacement, I will explain why. You deserve an honest answer, not a sales pitch.
What to Expect with Costs
Duct repair costs vary based on what we find. A simple inspection usually runs between $125 and $200. Targeted repairs for specific leaks can range from $200 to $600, while more comprehensive sealing can go up to $2,000. For hard-to-reach leaks, we offer Aeroseal, which typically ranges from $1,500 to $3,000.
We provide a clear, written estimate before we touch your equipment. We don't believe in hidden fees or surprise charges. We want you to know exactly what you are paying for and what kind of improvement you can expect in return.
Access and Scheduling
Working in Lake Balboa attics can be tough, especially during the summer. We plan our work carefully, taking into account attic access, electrical capacity, and the clearance around your outdoor condenser. We know your time is valuable, so we aim to be efficient and respectful of your home.
Whether you need a quick diagnostic or a full day of sealing, we will coordinate a time that works for you. We are a local, licensed contractor (CSLB #1073586), and we pride ourselves on showing up when we say we will and getting the job done right the first time.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to fix major duct leaks with standard duct tape. Real duct tape isn't actually meant for ducts—it dries out and peels off in the heat of an attic. We use professional-grade mastic and foil tape designed to hold up to the temperature swings in your attic.
Another mistake is ignoring the return side of the system. People focus on the supply registers because that's where the air comes out, but if your return ducts are leaking, your system is pulling in dirty air from the attic. Always make sure your technician checks both sides of the system.
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 insulation fibers, dust, and potential mold spores. Sealing these leaks doesn't just make your home more comfortable; it helps keep your air cleaner.
We take safety seriously. We ensure that all repairs are done to code and that your system is operating safely. If we find issues that could impact your health, we will bring them to your attention immediately so you can make an informed decision.
Is Duct Repair Right for You?
If your HVAC system is struggling to keep up with the Lake Balboa heat, start by asking yourself if the problem is consistent across the whole house or just in specific rooms. If it's specific rooms, duct leakage is a likely culprit. If the whole house feels like it's struggling, we should look at both the ductwork and the equipment itself.
My advice is to start with a professional diagnostic. Once we know the condition of your ducts, the decision becomes much easier. We will give you the facts, and you can decide what makes the most sense for your budget and 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 Lake Balboa customers say about duct repair
Verified reviews from homeowners in Lake Balboa 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.”
