Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Sealing Across Campbell
Duct sealing in Campbell, FL typically runs $450 – $1,200 for a whole-home system, with most single-family ranch homes falling in the $600 – $900 range. We seal supply and return plenums, patch disconnected flexible duct runs, and apply mastic to joint leaks so your conditioned air stops escaping into the attic or crawlspace.
Campbell’s mid-century housing stock keeps our crews busy year-round. We’re familiar with the galvanized steel trunk lines in the Prune Orchard neighborhood and the original flexible ductwork still running through attics off Campbell Avenue. When you call Hollis Air Duct Cleaning at (361) 326-5060, you’re talking to a live person who schedules Campbell jobs directly, not a national call center reading from a script.
Our dispatch team coordinates from the brand’s Miami office, but the technicians who show up at your Campbell door know this market. They’ve worked in the crawlspaces of downtown’s pre-1940 bungalows and the low-pitch attics of the 1960s ranch homes near Winchester Boulevard. That local familiarity means we spot problems faster and quote them accurately the first time.
Why Hollis Air Duct Cleaning Is Campbell’s Preferred Duct Sealing Company
We’ve built our reputation in Campbell by showing up inside the quoted window and leaving with the job done by the book. The Garrison Standard requires it, and our Campbell customers hold us to it.
Our reviews from Campbell homeowners consistently mention two things: the written price that didn’t budge at the door, and the uniformed technician who arrived when promised. We don’t compete on the lowest teaser quote. We compete on the quote you can trust.
Response time to Campbell is typically next-day or within 48 hours for standard duct sealing requests. We don’t promise same-day dispatch because duct sealing is a scheduled, precision job, not an emergency roadside fix. What we do promise is that your appointment window is real, your technician is background-checked and uniformed, and your price is locked in writing before any work begins.
We also understand Campbell’s unique position in the Santa Clara Valley. The city’s strict HVAC permit enforcement means real estate transactions here often require documented ductwork condition reports, especially in historic downtown and Prune Orchard. Our crews know how to document their work to satisfy those requirements, and we provide written reports that hold up at closing.
Duct Repair in Campbell
Duct Repair in Campbell addresses the physical damage that makes sealing impossible, from crushed flexible runs in tight attic spaces to rusted-out galvanized plenums in homes east of Campbell Avenue. When joints have separated completely, when rodents have chewed through flex duct in crawlspaces, or when a sagging trunk line is pulling connections apart, repair comes before sealing. Most duct repair jobs in Campbell run $350 – $800 depending on accessibility and the extent of replacement material needed.
Crushed or Collapsed Flexible Duct
Campbell’s 1950s – 1970s ranch homes often have flexible ductwork squeezed between roof trusses or draped over insulation where it wasn’t meant to bear weight. We replace the damaged run with properly supported new flex, sized to the original CFM rating, then seal all connections with mastic and mechanical fasteners.
Rodent Damage in Crawlspace Runs
Older homes near downtown Campbell and along Bascom Avenue frequently have crawlspace duct runs that squirrels or roof rats have accessed. We cut out chewed sections, install rodent-resistant hard duct where appropriate, and seal entry points before closing up. The work is documented with photos for your records.
Air Duct Sealing in Campbell
Air Duct Sealing in Campbell targets the leaks, gaps, and disconnected joints that bleed conditioned air into spaces where you don’t live. Our crews pressurize the system, measure leakage with a duct blaster, then seal accessible leaks using mastic compound, foil-backed tape rated for HVAC use, and mechanical fasteners at plenum connections. A typical whole-home sealing in Campbell costs $600 – $900 for a single-story ranch, with two-story homes or systems with extensive hard-to-reach attic runs trending toward the higher end.
Mastic Application at Joints and Seams
We brush on water-based duct mastic at every joint, seam, and connection point. Unlike tape alone, mastic remains flexible through Campbell’s hot attic cycles and cures to a permanent seal that outlasts standard foil tape by years. Our technicians carry Guardsman-rated mastic formulated for the temperature swings common in unconditioned Santa Clara Valley attics.
Plenum and Trunk Line Reinforcement
The connection between your air handler and the main trunk line is the highest-pressure point in the system and the most common source of major leakage. We rebuild or reinforce these plenum connections with sheet metal screws and two coats of mastic, then verify the seal under operating pressure before we leave.
Trusted Brands We Service in Campbell
Our vans carry sealing and repair materials from Rotobrush, Nikro, and Guardsman, the same professional-grade products commercial HVAC contractors use in Campbell’s larger buildings. We stock local parts for common Campbell systems, including replacement flex duct, mastic, and mechanical fasteners sized for the galvanized trunk lines found in mid-century ranch homes throughout the city. That inventory means most Campbell jobs are completed in a single visit without waiting on supplier delivery. When we encounter a system with Honeywell or Aprilaire filtration components that need resealing after duct modification, we have the adapters and gaskets on hand to do it right.
Common Duct Sealing Problems We See in Campbell Homes
- Original galvanized trunk lines with rusted seams. Campbell’s 1950s – 1970s ranch homes often have steel trunk lines that have corroded at the longitudinal seams, especially in homes near the foothills where attic humidity spikes during Santa Clara Valley temperature swings. We seal what we can and flag sections that need replacement.
- Disconnected flexible duct runs in low-clearance attics. The shallow-pitch roofs common in Campbell’s postwar subdivisions leave little room to maneuver, and original flex duct has often pulled loose from boots or collapsed onto insulation. We reconnect, support, and seal every run we can access safely.
- Leaky return air pathways pulling attic dust. In Campbell’s older homes, especially the pre-1940 cottages downtown, return air often travels through wall cavities or joist bays that were never properly sealed. We seal accessible leakage points and recommend hard duct conversion where wall cavity returns are drawing in particulates.
- Wildfire smoke residue degrading tape adhesives. Campbell’s exposure to regional wildfire events has loaded attics with fine particulates that settle on duct surfaces and accelerate the failure of older tape seals. We remove degraded tape and reseal with mastic rated for contaminated surfaces.
Pricing for Duct Sealing in Campbell, FL
Duct sealing in Campbell runs $450 – $1,200 for a complete residential system, with most single-story homes in the $600 – $900 range. Two-story homes, systems with extensive hard duct in tight attics, or jobs requiring significant repair before sealing can reach $1,000 – $1,200. What moves the price: the linear footage of ductwork, the ratio of accessible to inaccessible runs, whether we need to remove and replace degraded flex duct before sealing, and the condition of the plenum connections at the air handler.
We do not quote per-vent teaser prices that balloon once we’re inside. We give one flat price per system, agreed in writing before any work starts. That price includes the duct blaster test to measure your leakage before and after, all materials, and the 365-Day Done Right Promise. If a seal fails within a year, we return and make it right at no charge, including a free second visit.

Yes, we seal ducts throughout Campbell, from the historic cottages downtown to the mid-century ranches in Prune Orchard and the subdivisions near Winchester Boulevard. Each area presents different ductwork challenges, and our crews are familiar with all of them.
We do not classify duct sealing as an emergency service. If your system has failed completely, we recommend contacting an HVAC contractor for immediate repair. Once the system is operational, we can assess and seal the ductwork to prevent recurrence.
Campbell’s pricing sits in line with other Santa Clara Valley markets, though the high concentration of mid-century homes with original ductwork here means we encounter more repair-and-seal combinations than in newer-built suburbs. That can push some Campbell jobs toward the higher end of our range, but we quote the full scope in writing before starting.
Every duct sealing job in Campbell is covered by our 365-Day Done Right Promise. If any seal fails within one year of service, Hollis returns to repair or reseal at no charge, including a free second visit. The guarantee is backed in writing on every invoice, not offered verbally and forgotten.
