Duct Repair & Sealing in Hollywood, CA
If your Hollywood home is running the AC harder than ever but rooms still feel stuffy or uneven, leaking and deteriorating ductwork is usually the culprit — not your HVAC unit. Pure Air Duct Cleaners serves the 90028 ZIP and surrounding blocks with professional Duct Repair & Sealing performed by Larry Torres himself, not a subcontractor sent in his place. Call us at (844) 734-2955 for a free estimate — we’re familiar with Hollywood’s housing stock and we’ll tell you exactly what we find.
Why Pure Air Duct Cleaners Is Hollywood’s Preferred Duct Repair & Sealing Company
We’ve built our reputation across Hollywood one job at a time — and 288 verified customers with a 4.9-star average rating aren’t a marketing claim, they’re a track record. Larry Torres is the owner and the lead technician on every job, which means when we show up at your door on Franklin Avenue or off Beachwood Drive, the most experienced person in the company is the one crawling into your crawlspace. You’re not getting a rotating crew of unfamiliar faces — you’re getting the business owner, accountable for every seal and every repair.
Hollywood’s dense residential neighborhoods present duct systems that require genuine local familiarity, not a generic service call. We know that the 1920s bungalow courts near Gower Street typically have ductwork retrofitted into wall cavities that were never designed for it, and we bring the right equipment — professional-grade Rotobrush and Nikro systems — not a shop vac and a caulk gun. That combination of local knowledge and professional tools is why customers in Hollywood keep calling us back and keep leaving five-star reviews.
Our Duct Repair & Sealing Services in Hollywood
Duct Sealing
Leaky duct connections are the single most common energy drain we find in Hollywood homes, particularly in mid-century apartment buildings along corridors like Franklin Avenue where original metal connections have separated over decades of thermal expansion and contraction. We apply professional-grade mastic sealant — not off-the-shelf tape that fails within a season — to close gaps at every joint, collar, and transition. A properly sealed system in a Hollywood home can reduce HVAC energy waste by 20–30%, a meaningful number when your AC is running hard six months of the year.
Flex Duct Repair
Flex duct — the corrugated, flexible tubing added to countless Hollywood homes during 1970s and 1980s retrofits — degrades faster than most homeowners realize, especially in attic spaces that bake at well over 120°F during a Hollywood summer. Tears, kinks, and disconnected sections in flex duct quietly dump conditioned air into your attic rather than into your living room. We locate every compromised section, repair or replace it, and re-secure it so it stays put. A typical flex duct repair on a single run in Hollywood runs $150–$350, depending on access and the length of the damaged section.
Metal Duct Repair
Galvanized sheet-metal ductwork in Hollywood’s older apartment buildings along Gower Street and throughout the 90028 core has often gone 40 or 50 years without service — and it shows. We regularly find corroded seams, failed take-offs, and sections where previous patch attempts used nothing more than deteriorated duct tape that lost its adhesion years ago. Larry welds, re-sections, and properly fastens sheet-metal duct runs rather than layering more temporary fixes on top of old ones. Metal duct repair in Hollywood typically ranges from $200–$600 per section depending on duct size and the extent of the damage.
Duct Insulation
Uninsulated or under-insulated duct runs are a serious efficiency problem in Hollywood specifically, because the Hollywood Hills block the marine layer that keeps coastal neighborhoods cooler — meaning attic temperatures here run consistently higher than in Santa Monica or Culver City. When your supply ducts run through a superheated attic without adequate insulation, the air you paid to cool is warming up before it ever reaches a register. We wrap exposed duct runs with R-6 or R-8 insulation rated for Southern California attic conditions, and we replace damaged insulation that’s accumulated ash or debris from the Santa Ana events that funnel through the Cahuenga Pass. Duct insulation service in Hollywood runs $300–$900 for a typical single-family home, depending on total linear footage.
Trusted Brands We Service in Hollywood
We work with the brands that actually belong in a properly equipped air-quality operation: Honeywell and Aprilaire for filtration and ventilation components, Abatement Technologies and Guardsman for contaminant control and sanitizing applications. When a Hollywood job calls for a replacement part or a sealant product with real performance specs behind it, we’re not improvising — we stock what we need for the most common duct configurations we encounter in 90028, and we can typically complete repairs and sealing in a single visit without a parts delay.
Common Duct Repair & Sealing Problems We See in Hollywood Homes
- Ash and carbon contamination in duct interiors from hillside brush fires: Hollywood’s flatlands sit directly below the Hollywood Hills, and the Cahuenga Pass acts as a natural wind funnel during Santa Ana events, pushing wildfire smoke and fine ash from above Runyon Canyon and Beachwood Canyon directly into HVAC intakes below. After a significant fire season, we routinely pull visible soot from supply vents in buildings near Beachwood Drive that otherwise look completely well-maintained — this is a season-after-season problem in 90028, not a one-time event.
- Poorly routed, constricted duct runs in pre-war bungalows and bungalow courts: The Spanish Colonial Revival bungalows and early-studio-era apartment buildings that dominate Hollywood’s residential core were built in the 1920s–1940s — decades before forced-air HVAC existed. Ductwork was retrofitted into spaces that were never designed for it, producing tight bends, undersized runs, and connections that were never properly sealed in the first place. These systems trap debris efficiently and lose pressure constantly.
- Aging galvanized sheet-metal ductwork with failed seams: Mid-century apartment buildings along Franklin Avenue and Gower Street are full of original galvanized ductwork that’s now 60–70 years old. The factory-applied mastic on those old seams has long since dried out and cracked, and the duct tape added during past service calls is equally brittle. Conditioned air leaks out at every joint while unconditioned attic air leaks in — a double loss that drives up utility bills and reduces system performance.
- Overworked systems accelerating duct wear: Because the Hollywood Hills block marine layer penetration from the coast, Hollywood runs several degrees warmer and drier than neighboring West Hollywood or Silver Lake. Air conditioning systems here cycle more air — and more particulates — through duct systems every summer than equivalent systems on the Westside. That extra runtime accelerates deterioration of flex duct connections, insulation, and mastic seals, meaning Hollywood homes need duct maintenance on a shorter cycle than homeowners typically expect.
Pricing for Duct Repair & Sealing in Hollywood, CA
Here’s what duct repair and sealing actually costs in the Hollywood market, so you’re not guessing. A full duct sealing service using mastic sealant on a single-family home in 90028 typically runs $400–$800. Spot repairs — a single disconnected flex duct section or a failed collar — generally fall in the $150–$350 range. Metal duct repair runs $200–$600 per section. Duct insulation for a typical Hollywood home attic runs $300–$900 depending on linear footage and current insulation condition. What moves the number up is access difficulty — older bungalows with tight crawlspaces or retrofitted duct runs in wall cavities take more time. What moves it down is catching a problem early before it requires a full section replacement. Every estimate from us is free, and we’ll walk you through exactly what we found before any work begins.
