When Reseda residents need duct repair, LC Heating & Air delivers same-day service backed by 20+ years of working in the LA market. Reseda occupies the central-western San Fernando Valley, a residential neighborhood characterized by its 1950s-1960s post-war housing stock and its family-oriented community. The area shares the Valley's challenging climate — intense summer heat requiring reliable air conditioning and cool enough winter mornings to make heating necessary from November through March. 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
Reseda's mid-century housing stock typically has HVAC systems that have been replaced at least once since original construction, but the ductwork is often original. Decades-old flex duct in Valley attics deteriorates from sustained heat exposure — connections loosen, insulation compresses, and air leakage increases over time. We evaluate ductwork condition on every service call and provide honest guidance on when duct replacement or sealing will meaningfully improve comfort and efficiency.
Neighborhood Context
Reseda represents the accessible, working-family neighborhoods of the Valley where HVAC investment decisions are practical rather than luxury-oriented. We respect that and always present repair-vs-replace options with clear cost analysis. When a $400 repair can extend a system's useful life by three to five years, we recommend the repair. When throwing money at an aging system is no longer economical, we say so directly and present replacement options at multiple price points.

What Reseda customers say about duct repair
Verified reviews from homeowners in Reseda and nearby neighborhoods who used our duct repair service.
“LC did a full duct inspection and found we were losing 35% of our conditioned air through disconnected joints in the attic. After sealing and repairing, the difference was immediate — better airflow, lower bills, no more hot spots.”
“Called LC after another company told me I needed a $12,000 system replacement. LC diagnosed a bad TXV valve and fixed it for $380. Honest company — they saved me from an unnecessary replacement.”
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
