I'm Leo, owner and lead technician at LC Heating & Air. When I walk into a home in Tujunga, I often find that the comfort problems homeowners are dealing with—like one room being stifling hot while another is freezing—aren't actually caused by the furnace or AC unit itself. They’re caused by the ductwork. If your ducts are leaking, you’re paying to cool your attic instead of your living room.
The Department of Energy estimates that typical residential duct systems lose 20–30% of conditioned air through leaks before it ever reaches your living space. In our climate, that adds up to a lot of wasted money. I focus on finding those hidden leaks, assessing whether they can be fixed or if they need replacement, and giving you a clear, honest path forward.

Local HVAC considerations
Common Duct Issues in Tujunga Hillside Homes
Tujunga’s hillside and canyon properties present unique challenges for ductwork. Because of the way these homes are built, we often see crushed flex duct caused by tight attic access or previous work done in cramped spaces. When a duct is crushed, it restricts airflow to specific rooms, making your HVAC system work much harder than it needs to.
We also frequently find disconnected duct sections at joints and take-offs, or failed mastic at supply plenums. In our local climate, sun exposure and elevation changes can create significant room-by-room comfort differences. If your ducts aren't sealed properly, that attic heat is being pulled directly into your living area, which is why your system might run constantly without ever making the house feel truly comfortable.
How We Diagnose Your System
I don't believe in guessing. When I arrive, I start by measuring airflow at your registers and inspecting the accessible ductwork. We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air you are losing. This gives us a baseline number so we know if the leaks are minor or if they are significant enough to be costing you hundreds of dollars a year in wasted energy.
Once we have the data, I’ll show you what we found. If the system is worth repairing, we’ll fix it. If the damage is too widespread or the materials have deteriorated beyond the point of a reliable seal, I’ll tell you that, too. You’ll get a written estimate before we touch a single piece of equipment.
Working with Tujunga’s Unique Architecture
Tujunga has a mix of older custom homes and hillside properties that weren't always designed with modern HVAC service access in mind. Equipment placement, ladder access, and line-set routing can be tricky here. I take these factors into account before we start any work.
If your home has tight-access mechanical areas, we plan our approach carefully. We don't just force a repair; we look at how the ductwork is routed to ensure that whatever we fix will actually stay fixed. My goal is to provide a solution that fits your specific property, not a generic, one-size-fits-all fix that ignores the reality of your home's layout.
Repair or Replace? An Honest Assessment
Homeowners often ask me if they should just replace all their ducts. My answer is always the same: it depends on the condition of what’s already there. If you have a few disconnected joints or a small tear in a flex duct, a repair is usually the most practical and cost-effective choice.
However, if the ductwork is original to an older home and the material is crumbling, or if the layout is fundamentally flawed, patching it up is just throwing good money after bad. I’ll be honest with you about whether a repair will actually solve your comfort issues or if you’re just delaying the inevitable. We want to make sure the work we do provides a real, measurable improvement.
Understanding the Costs
I provide upfront, written estimates so you know exactly what you’re paying for. Targeted repairs for specific leaks usually range from $200 to $600. For more comprehensive sealing of a full system, costs typically fall between $800 and $2,000. If we use Aeroseal to seal leaks from the inside that we can’t reach manually, that usually runs between $1,500 and $3,000.
These costs are investments in your home's efficiency. By sealing 20–30% of duct leakage, you can often reduce your HVAC energy consumption by 15–25%. That’s a payback that usually shows up in your utility bills within months, not years.
Air Quality and Safety
Duct leaks aren't just about losing conditioned air; they’re about what you’re breathing. If your return ducts have leaks in the attic, your system is pulling in insulation fibers, dust, and potentially mold spores, and then blowing them directly into your living space. This is a common cause of respiratory irritation for homeowners.
Supply leaks can also cause issues by backdrafting attic air into your rooms. When we seal your ducts, we aren't just improving comfort; we’re cleaning up the air that circulates through your home. It’s a practical step toward a healthier living environment.
Scheduling Your Service
I know your time is valuable. Because I operate LC Heating & Air as a local contractor, I don't have the overhead or the corporate red tape that slows down larger companies. When you call (323) 970-3113, you’re talking to someone who understands the logistics of working in Tujunga.
We coordinate our visits to account for the specific access needs of your property, whether that means navigating narrow roads or planning for difficult ladder access. We aim to get your system back to peak performance as efficiently as possible, with minimal disruption to your day.
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 swings in an attic. It dries out, cracks, and falls off, leaving you with the same leak you started with. We use professional-grade mastic and foil tape designed for HVAC systems.
Another mistake is assuming that 'cleaning' your ducts will solve airflow problems. Cleaning removes dust, but it doesn't fix leaks or crushed ducts. If you have uneven temperatures, you need a diagnostic, not just a vacuuming. Don't pay for a service that doesn't address the root cause of your comfort issues.

What Tujunga customers say about duct repair
Verified reviews from homeowners in Tujunga 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.”
