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 nickname 'The Media Capital of the World' reflects its concentration of entertainment industry studios, but for HVAC purposes, Burbank is primarily a residential city with one of the San Fernando Valley's largest owner-occupied housing stocks. Summer temperatures in Burbank regularly exceed 95 degrees Fahrenheit, and the heat island effect is significant. LC Heating & Air services all of Burbank's residential areas, from the homes south of Magnolia Boulevard to the hillside properties in the Rancho area and the neighborhoods adjacent to the Verdugos. We understand the specific demands that Valley heat puts on aging AC units.

Duct sealing is one of the highest-ROI home energy improvements available to Los Angeles homeowners. When conditioned air leaks into attic or wall cavities before reaching the living space, you're paying to condition space you don't occupy. Studies of California homes consistently show 20–30% duct leakage in older homes—and every percentage point of leakage reduction shows up directly in your utility bill. We use Burbank-specific design temperature data in all our load calculations to ensure your system performs as expected.

Local HVAC Challenges in Burbank

Burbank's location in the San Fernando Valley means it experiences the Valley's characteristic temperature extremes—hotter summers and cooler winters than the LA basin—but without the coastal cooling influence that moderates temperatures in west-side neighborhoods. Valley homes need HVAC systems sized for higher cooling loads than coastal LA homes of equivalent size.

Many Burbank homes were built in the 1950s through 1970s for families of studio and entertainment industry workers. While the construction is solid, these homes are now reaching or past the end of their original HVAC system life. We often find that ductwork in these homes has degraded, leading to significant leakage into attics, crawl spaces, or wall cavities instead of reaching your living areas.

Navigating Burbank's Unique Housing

Whether you live in a single-family home in Magnolia Park or a multi-family property near the Media District, we understand the specific access challenges. Our work often requires coordination with HOAs, tenants, rooftops, shared walls, and limited parking. We are familiar with the permitting requirements of the City of Burbank and work closely with Burbank Water and Power for rebate processing.

We prioritize clear communication regarding building access windows and mechanical closet constraints. If your home has rooftop package units or compact mechanical closets, we plan our service to minimize disruption while ensuring the job is done right.

Our Diagnostic Process

We don't guess. We start with a duct blaster test to quantify existing leakage as a percentage of your system's total airflow. This gives us a baseline number so you can see exactly how much air is being lost before we start any work.

After the testing, we evaluate the duct type and accessibility. We then recommend the best approach: manual mastic sealing for accessible joints and plenums, or Aeroseal internal sealing for distributed leaks that are hidden behind walls or in tight attic spaces. We finish with a post-sealing verification test to prove the results.

Repair vs. Replace: Making the Right Call

If your system is worth repairing, we will tell you. If the pattern of damage points to replacement, we will explain why. Often, duct sealing can extend the life of an existing system by reducing the load on the blower motor and preventing the unit from running constantly to reach the thermostat setpoint.

However, if the ductwork is severely crushed, contaminated, or improperly sized, sealing may not be enough. We provide honest, written estimates so you can make an informed decision based on the current state of your equipment.

Understanding Costs and Rebates

Duct sealing costs vary based on the size of your home and the complexity of the duct system. Manual mastic sealing typically ranges from $400 to $1,200, while Aeroseal internal sealing ranges from $1,500 to $3,000. Both options include the required duct blaster testing.

Because we are a local contractor, we stay updated on Burbank Water and Power rebate programs. We provide the necessary documentation to help you navigate these incentives when you choose high-efficiency upgrades.

Scheduling and Access

We know that your time is valuable. We offer same-day scheduling options for our Burbank neighbors. Whether you are in the Rancho Equestrian District or near the Airport, we arrive prepared with the tools to handle the specific access requirements of your property.

We are fully licensed (CSLB #1073586) and insured. When we schedule a visit, we arrive on time, ready to perform the diagnostics and provide a clear, written estimate before any work begins.

Common Duct Sealing Mistakes

The biggest mistake we see is the use of standard silver 'duct tape' on HVAC systems. It dries out and fails within a few years. We only use professional-grade mastic or foil-backed HVAC tape that is rated for the life of the system.

Another mistake is skipping the pre- and post-testing. Without a duct blaster test, there is no way to verify that the sealing actually worked. We perform these tests on every job to ensure compliance with California Title 24 standards.

Health and Safety

Your indoor air quality is our priority. The Aeroseal process uses a non-toxic polymer that is safe for your home. We recommend vacating the home during the 60–90 minute injection process as a precaution, but you can return immediately after the system has run to clear the air.

We also ensure that all sealing materials are applied correctly to prevent any risk of chemical off-gassing. Our goal is a cleaner, more efficient home environment for you and your family.

Is Duct Sealing Right for Your Home?

If your energy bills are high for your home size, or if you notice uneven temperatures between rooms, duct sealing is often the most effective first step. It is a permanent solution that stops conditioned air from leaking into your attic or crawl space.

If you are planning an HVAC replacement, sealing your ducts is essential to maximize the efficiency of your new equipment. We are happy to inspect your system and provide an honest assessment of whether sealing will solve your comfort issues or if further repairs are needed.

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.

Frequently asked questions

Duct Sealing in Burbank — common questions

How much energy can duct sealing save?
Studies of California homes find average savings of 15–25% of HVAC energy use after professional duct sealing. We quantify your specific leakage before sealing so you can estimate your expected savings.
Who offers duct sealing near me in Burbank?
LC Heating & Air provides duct sealing in Burbank and nearby LA neighborhoods, with same-day scheduling when available. Emergency calls are answered 24/7, typically within 30 minutes — call (323) 970-3113. Licensed CSLB #1073586.
What is the difference between mastic and duct tape?
Standard 'duct tape' dries out and fails. Mastic is a thick, flexible sealant that remains pliable and adheres permanently to duct joints.
How does Aeroseal work?
Aeroseal pressurizes your duct system and injects a fine mist of polymer particles that accumulate on the edges of leaks, sealing them from the inside out.
Is Aeroseal safe?
Yes. The polymer used is non-toxic and is the same material used in chewing gum and many food products.
Does duct sealing require permits in California?
Standalone duct sealing generally doesn't require a permit, but it is often required as part of a permitted HVAC replacement project.
