I'm Leo, owner of LC Heating & Air. If your home in Lincoln Heights has rooms that never seem to get comfortable, or if your energy bills keep climbing, the problem might not be your AC unit itself—it’s often the ductwork. In our older neighborhoods, we see a lot of systems losing 20–30% of their conditioned air through leaks before it ever reaches your living space.
I don't believe in guessing. My team and I use professional duct pressurization testing to find exactly where your system is leaking. Whether it's a disconnected run in a tight attic or crushed flex duct in a mechanical closet, we provide a clear, written estimate so you know exactly what needs to be fixed and why.

Common Duct Issues in Lincoln Heights
Lincoln Heights has a unique mix of older multifamily properties, apartments, and compact homes. Because of this, we frequently encounter ductwork that has been compromised by limited space. We often find crushed flex duct in cramped mechanical closets or leaks at joints that were never properly sealed during original construction.
Another issue we see often is the 'heat-island' effect. In our area, rooftop equipment and attic-run ducts are exposed to intense heat. If those ducts have even small leaks, they aren't just losing air—they are sucking in hot, dusty attic air and blowing it directly into your living room. This makes your system work much harder than it needs to.
Working in Older LA Buildings
Working in Lincoln Heights means navigating specific building constraints. Whether you are in a mixed-use building, a condo, or an older home, access is almost always a factor. We are experienced in coordinating with HOAs and tenants to ensure we can reach rooftop units or shared wall mechanical spaces without causing a disruption.
Because our buildings are often older, we don't just look for the obvious damage. We look at how the system was originally routed. Sometimes, the issue isn't just a leak—it's that the duct design itself is struggling to keep up with modern cooling demands. We will tell you honestly if a repair will solve your comfort issue or if the system design is the real bottleneck.
Our Diagnostic Process
We don't start by selling you a repair. We start by measuring. We perform a duct blaster test to pressurize your system, which allows us to quantify exactly how much air you are losing. We also check airflow at every register to see which rooms are being starved of air.
Once we have the data, I walk you through it. We look at the accessible sections, check for torn liners, and inspect the connections at the plenum. You will get a written plan that explains what we found and what we recommend doing to fix it.
Repair vs. Replacement: The Honest Truth
A lot of contractors will push for a full duct replacement the second they see a leak. That isn't how I operate. If your ductwork is in generally good shape but has a few disconnected joints or small tears, a repair is often the most practical and cost-effective choice.
However, if the ducts are severely undersized, collapsing throughout the home, or made of outdated materials that are falling apart, I will tell you that a repair is just a band-aid. If the system is worth repairing, we will fix it. If the pattern points to a larger issue that will cost you more in the long run, I will explain why replacement is the better investment.
Understanding Your Costs
Duct repair costs vary based on what we find. A simple, targeted repair for a disconnected section might be straightforward, while sealing a full system or using Aeroseal for inaccessible leaks involves more time and equipment. We provide a written estimate before we start, so you aren't surprised by the final bill.
Remember that the cost of repair is often offset by the energy savings you get immediately after. When you stop paying to cool your attic, your AC doesn't have to run as long, which saves you money on your monthly utility bills.
Air Quality and Safety
Duct leaks aren't just an efficiency problem; they are an air quality problem. When your return ducts leak in an attic or wall cavity, they pull in dust, insulation fibers, and whatever else is hiding in those spaces. That air is then pushed directly into your living room.
Sealing these leaks helps keep your home cleaner and prevents that musty smell that often comes from dirty attic air being drawn into the system. We take your health seriously by ensuring that the air you breathe is coming from inside your home, not from your attic or crawl space.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to 'fix' leaks with standard duct tape. Real duct tape—the kind you buy at the hardware store—actually fails quickly in the heat of an attic. It dries out, cracks, and falls off, leaving you with the same leak you started with.
Another mistake is ignoring the airflow balance. Just sealing a leak isn't always enough if the system was never balanced properly. We check the airflow at your registers to make sure that once the leaks are sealed, the air is actually reaching the rooms that need it most.
Scheduling Your Service
We know that living in Lincoln Heights often means dealing with tight parking, shared walls, and specific building access windows. When you call us at (323) 970-3113, let us know if there are any special access requirements for your property.
We work with you to find a time that fits your schedule. Because we are a local, licensed contractor (CSLB #1073586), we respect your time and your property. We show up when we say we will, and we leave the workspace clean.

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