When Burbank residents need duct sealing, LC Heating & Air delivers same-day service backed by 20+ years of working in the LA market. 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 city's predominantly flat topography means heat island effects are significant in its denser commercial and residential corridors. That local knowledge means our technicians arrive knowing what equipment and access challenges to expect — cutting diagnostic time and getting repairs done faster.
### What Duct Sealing Accomplishes 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.
Overview
### Manual Sealing vs. Aeroseal LC Heating & Air offers two duct sealing approaches. Manual sealing uses mastic (a durable, flexible sealant applied by hand) and foil tape at accessible duct joints, take-offs, supply and return plenums, and connection points. This is the right approach when significant leakage locations are accessible and the duct system is in otherwise good structural condition. Aeroseal internal sealing is our solution for duct systems where significant leakage is distributed throughout the system in locations that aren't manually accessible — it seals from the inside out using a pressurized polymer aerosol that deposits on and seals leak sites as air passes through them.
### California Energy Code and Duct Sealing California Title 24 requires duct sealing testing (duct blaster test) as part of any HVAC replacement permit — and requires that systems failing the test be sealed to meet the leakage standard before permit signoff. If you've replaced HVAC equipment without a permit, or had a permitted replacement that failed to test the ducts, your system may have significant unsealed leakage.
### What You'll Notice After Duct Sealing Homeowners consistently report three immediate improvements after duct sealing: rooms that were previously hard to condition are now comfortable, the HVAC system runs for noticeably shorter cycles to reach the thermostat setpoint, and utility bills decrease. These improvements are permanent — properly applied mastic and Aeroseal are rated for the life of the duct system.
Local HVAC Challenges
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. We use Burbank-specific design temperature data in all our load calculations rather than generic Los Angeles figures.
Neighborhood Context
Many Burbank homes were built in the 1950s through 1970s for families of studio and entertainment industry workers — solid construction but now reaching or past the end of original HVAC system life. The city has an active permitting department that we work with regularly. Burbank Water and Power (independent utility, not LADWP) offers rebates on qualifying high-efficiency HVAC equipment that we are experienced in accessing for our customers.

What Burbank customers say about duct sealing
Verified reviews from homeowners in Burbank and nearby neighborhoods who used our duct sealing 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.”
