When Westwood residents need duct repair, LC Heating & Air delivers same-day service backed by 20+ years of working in the LA market. Westwood encompasses the area surrounding UCLA, bounded roughly by Bel Air to the north, Brentwood to the west, and Century City to the south. The neighborhood has an unusually diverse mix of housing: single-family homes in the Westwood Hills area, large apartment and condominium buildings along Wilshire Boulevard, and student-oriented rental properties near the UCLA campus. That local knowledge means our technicians arrive knowing what equipment and access challenges to expect — cutting diagnostic time and getting repairs done faster.
### The Hidden Cost of Leaky Ducts in LA Homes 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 Los Angeles, where AC runs heavily from May through October, that means you're paying to cool your attic rather than your living room every summer. Duct repair is one of the highest-return HVAC improvements a Los Angeles homeowner can make — and it directly addresses the most common cause of comfort complaints (uneven temperatures, rooms that are always too hot or too cold).
Overview
### Signs Your Ducts Need Repair Most homeowners have no idea their ducts are leaking because the leaks are hidden in attics, crawl spaces, and wall cavities. We identify duct problems through a combination of airflow measurements (comparing what the equipment produces to what each room receives), duct pressurization testing, and visual inspection of accessible duct sections. Common damage we find: disconnected duct sections at joints and take-offs, torn flex duct inner liners, crushed flex duct from attic access foot traffic, failed mastic at supply plenums, and deteriorated tape joints on older sheet metal ductwork.
### Repair Methods Duct repair methods depend on the type of damage and duct material. Disconnected flex duct sections are reconnected and sealed with mastic and foil tape. Torn inner liners require section replacement. Sheet metal joints are sealed with mastic. For systems with widespread small leaks throughout the distribution system, Aeroseal duct sealing (an internal pressurized sealing process) can address leaks that aren't accessible for manual repair.
### Before and After Documentation We document duct leakage before and after repair using duct blaster testing — a pressurization test that quantifies total duct leakage as a percentage of system airflow. This gives you measurable proof that the work improved your system's performance.
Local HVAC Challenges
Westwood's mix of single-family homes and high-rise condominiums means we work with both traditional split-system HVAC and commercial-grade building systems. Condo buildings along the Wilshire Corridor typically use centralized chiller plants with individual fan coil units — maintenance and repair on these systems requires different expertise than residential split systems. We service both types and can work with HOA maintenance schedules and building management companies.
Neighborhood Context
The UCLA student rental market means many Westwood properties have HVAC systems that see heavy use and may not receive the maintenance that owner-occupied homes get. We work with property managers throughout Westwood to establish preventive maintenance programs that reduce emergency calls and extend equipment life. For homeowners in the residential areas, we provide the same thorough service we deliver throughout our coverage area — honest diagnosis, fair pricing, and quality work.

What Westwood customers say about duct repair
Verified reviews from homeowners in Westwood and nearby neighborhoods who used our duct repair service.
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
“We converted our garage into an ADU and needed HVAC. LC installed a Mitsubishi single-zone mini split — permits, electrical, everything. The unit is so quiet you can barely hear it running. Our tenant loves it.”
