I'm Leo, the owner of LC Heating & Air. I spend a lot of time in attics across Arcadia, and I can tell you that most homeowners have no idea their ductwork is failing until they see their energy bills or notice one room is always hotter than the rest. If your HVAC system is working hard but your home doesn't feel comfortable, the problem is often hiding in the ducts, not the equipment itself.
We focus on practical, honest repairs. Whether it's a disconnected flex duct, a crushed run, or leaky plenums, we identify the issue, show you the evidence, and give you a written estimate. We don't believe in pushing for a full replacement if a repair will get your system running the way it should.

Local HVAC considerations
The Hidden Cost of Leaky Ducts in Arcadia
The Department of Energy estimates that typical residential duct systems lose 20–30% of conditioned air through leaks before it reaches the living space. In Arcadia, where we deal with significant heat, that means you are paying to cool your attic rather than your living room all summer long. Duct repair is one of the highest-return HVAC improvements a homeowner can make.
In our local housing stock—which ranges from older homes to newer remodels—we often find common patterns: disconnected sections at joints, torn inner liners on flex ducts, and crushed runs caused by foot traffic in attics. These leaks don't just waste energy; they pull in dust and insulation fibers from your attic, which directly affects your indoor air quality.
Why Arcadia Homes Need Specific Duct Care
Arcadia has a mix of single-family homes, duplexes, and smaller multifamily buildings. Because these homes were built in different eras, the ductwork is rarely uniform. Older homes might have sheet metal ducts with failing tape, while newer remodels might have poorly installed flex duct that has been kinked or crushed during construction.
Before we recommend any repair, we check the access, the duct condition, and the airflow. We don't treat every system the same because every attic and crawl space in this city presents different challenges. Understanding your home's specific layout is the only way to ensure a repair actually solves your comfort problem.
Our Diagnostic Process
We don't guess. We start by measuring airflow at your registers to see what's actually reaching your rooms. We then perform a duct pressurization test (a duct blaster test) to quantify exactly how much air is leaking out of the system. This gives us a clear number to work with.
Once we have the data, we inspect the accessible ductwork. We look for disconnected joints, torn liners, and failed mastic. We then sit down with you and explain what we found. You'll get a written estimate for the repair before we touch a single piece of equipment.
Repair vs. Replace: An Honest Look
A lot of companies will tell you that any duct issue requires a full system replacement. That is rarely the case. If your ducts are generally in good shape but have specific leaks or disconnected runs, a repair is often the most cost-effective solution.
However, if the ductwork is severely undersized, collapsing throughout the entire house, or made of materials that are literally falling apart, we will tell you that a repair is just a temporary fix. If the system is worth repairing, we will fix it. If the pattern points to replacement, we will explain exactly why so you can make an informed decision.
Understanding Repair Costs
The cost of duct repair varies based on the complexity of the job. Targeted repairs to specific disconnected sections usually range from $200 to $600. For more comprehensive sealing of a full system, costs can range from $800 to $2,000. If we use Aeroseal for hard-to-reach leaks, that typically falls between $1,500 and $3,000.
We provide transparent, written pricing. We don't hide costs, and we don't add on unnecessary services. Our goal is to provide a repair that makes sense for your budget and your home's needs.
Access and Scheduling
We know your time is valuable. When we schedule a visit, we arrive prepared to inspect the access points, electrical setup, and duct layout. Because many Arcadia homes have tight attics or unique crawl spaces, we plan our work to minimize disruption to your home.
We offer same-day service options when possible and always ensure our team has the right tools for your specific home layout. We take pride in being a local contractor, not a corporate franchise, so you get direct communication from start to finish.
Common Mistakes to Avoid
The biggest mistake I see is homeowners trying to fix duct leaks with standard duct tape. It doesn't hold up in the heat of an attic and will fail within months. Another mistake is ignoring the 'whistling' sounds coming from your walls; that is almost always a sign of a significant leak that is forcing your blower motor to work much harder than it needs to.
Don't assume that a high energy bill is just 'part of living in LA.' If your system is running constantly but your house is still uncomfortable, it's a sign that your ducts are likely leaking. Getting a professional diagnostic is the only way to stop the waste.
Health and Safety
Duct leaks are a health issue as much as a comfort issue. When your return ducts leak in the attic, they pull in dust, insulation fibers, and potential mold spores, distributing them directly into your living space. This is especially important if anyone in your home suffers from allergies or asthma.
By sealing your ducts, we aren't just improving airflow; we are cleaning up the air you breathe. We take safety seriously, ensuring that all repairs meet local standards and that your system operates as intended without drawing in air from unconditioned spaces.
Is Your System Worth Repairing?
If you are unsure whether to repair or replace, look at the age of your equipment and the condition of the ducts. If the equipment is relatively new but the house is uncomfortable, a duct repair is almost always the right move. If the system is very old and the ducts are falling apart, we will help you weigh the cost of repairs against the long-term benefit of a new installation.
At LC Heating & Air, we don't have a 'sales quota.' We have a reputation to maintain in Arcadia. We will give you the straight talk you need to make the right decision for your home.

What Arcadia customers say about duct repair
Verified reviews from homeowners in Arcadia and nearby neighborhoods who used our duct repair service.
“AC wasn't cooling to setpoint even though it was running all day. LC found the condenser coils were completely clogged with cottonwood. Cleaned them on the spot and the system cooled my house 12 degrees in an hour.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
