Duct Cleaning & Air Duct Service in Burbank
LC Heating & Air provides duct cleaning in Burbank — including air duct cleaning, duct repair service, duct sealing, HVAC ductwork. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.
We repair and service all major HVAC brands in Burbank, including Carrier, Trane, and Goodman, and older or discontinued units. No matter the manufacturer, we diagnose the problem accurately and give you an upfront price before any work begins.
Burbank's location in the San Fernando Valley means it experiences significant temperature extremes. When your HVAC system has to fight against the heat, leaky ductwork makes the job much harder. 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.
I'm Leo, owner of LC Heating & Air. I see this all the time in Burbank—homeowners paying to cool their attics instead of their bedrooms. My team and I focus on finding these hidden leaks and providing practical, long-term solutions. Whether it's a simple reconnection or a more complex sealing job, we provide a written estimate and clear explanation before we start any work.

Duct diagnostics and efficiency
Common Duct Issues in Burbank Homes
Burbank's housing stock, ranging from mid-century homes to newer multifamily properties, often features aging ductwork. We frequently find disconnected sections at joints, torn flex duct inner liners, and crushed ducts caused by attic foot traffic. These issues are common in our area because of the intense heat cycles that cause materials to expand and contract over time.
We also see problems with ductwork in compact mechanical closets and rooftop package units. In these tight spaces, poor installation or lack of maintenance leads to failed mastic at plenums and deteriorated tape joints. If you notice whistling sounds or weak airflow in specific rooms, these are classic signs that your ducts need a professional look.
Understanding Burbank's Housing
Many Burbank homes were built between the 1950s and 1970s. While the construction is solid, the original HVAC systems and ductwork are often reaching the end of their service life. We understand the specific demands that Valley heat puts on this equipment.
Whether you live in the Rancho Equestrian District, Magnolia Park, or near the Media District, we are familiar with the local permitting requirements and the specific layout challenges of these neighborhoods. We work closely with Burbank Water and Power to help you navigate available rebates for qualifying equipment upgrades.
Our Diagnostic Process
We don't guess. We start by measuring airflow at your registers and inspecting all accessible ductwork. We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air is leaking from your system.
This data allows us to show you the problem in black and white. Once we have the numbers, we explain the repair options. If a repair is the right path, we provide a written estimate. If the system is too far gone, we will tell you that too.
Repair vs. Replacement
A common question I get is whether to patch a duct or replace the whole system. If your ducts are mostly intact with a few disconnected joints or small tears, a targeted repair is usually the best value. It restores airflow and efficiency without the cost of a full system overhaul.
However, if the ductwork is severely crushed, undersized for your home's cooling load, or made of outdated materials that are falling apart, replacement is often the more honest, long-term solution. We will never push for a replacement if a repair will reliably fix your comfort issues.
Cost and Efficiency Factors
Duct repair costs vary based on the complexity and accessibility of your system. Simple repairs might cost between $200 and $600, while comprehensive sealing or Aeroseal applications range from $800 to $3,000. We provide a clear, written estimate after our diagnostic so there are no surprises.
Keep in mind that sealing your ducts can reduce HVAC energy consumption by 15–25%. This isn't just about comfort; it's about lowering your monthly utility bills and reducing the wear and tear on your compressor and blower motor.
Scheduling and Access
We know that living in Burbank often means dealing with HOAs, shared walls, and limited parking. Our team is experienced in coordinating access windows to minimize disruption to your day.
We offer same-day scheduling and 24/7 emergency availability. Whether you are in a single-family home or a complex multi-use building, we handle the logistics so you can focus on getting your home comfortable again.
Health and Safety
Leaky ducts do more than waste energy—they can impact your indoor air quality. Return duct leaks in attics can pull insulation fibers, dust, and mold spores directly into your living space. Supply leaks can backdraft attic air into your home.
By sealing these leaks, we ensure that the air circulating through your home is cleaner and filtered through your HVAC system, not pulled from dusty, unconditioned attics.
Mistakes to avoid — Duct Repair in Burbank
Oversized equipment, skipped maintenance, and DIY refrigerant or gas work are frequent duct repair mistakes we correct in Burbank.
Closing too many registers or using the wrong filter MERV rating can starve airflow and shorten component life.
Making the Right Decision
Choosing between a repair and a replacement comes down to the condition of your equipment and your long-term goals. If your system is relatively new but your home feels uncomfortable, duct repair is often the missing piece of the puzzle.
If your system is aging and the ductwork is failing, we will help you weigh the cost of repairs against the efficiency gains of a new system. My job is to give you the facts so you can make the decision that makes the most sense for your budget.

What Burbank customers say about duct repair
Verified reviews from homeowners in Burbank and nearby neighborhoods who used our duct repair service.
“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.”
“Furnace was making a loud banging noise every time it started. LC diagnosed delayed ignition from dirty burners. Cleaned and tuned the whole system, tested CO levels, explained everything clearly. No upsell, fair price.”
“Emergency call at 11pm when our furnace cracked the heat exchanger. CO alarm was going off. LC came out at midnight, confirmed the danger, shut it down, and had a new furnace installed by the next afternoon.”
