Why Bellows Air Duct & Vent Co. Is Southwest Ranches’s Preferred Duct Repair & Sealing Company
We’ve been serving Broward County homeowners since 1984, and Southwest Ranches has become one of our most frequent call zones over the past two decades. The town’s unique blend of agricultural zoning and large custom estates creates duct problems we simply don’t see in Cooper City or Pembroke Pines - crushed flex duct from hay storage, ammonia-corroded metal seams, and mastic that degrades faster under constant humidity and organic load.
Our technicians are background-checked, uniformed, and trained specifically for Southwest Ranches conditions. They carry Nikro and Honeywell equipment rated for the extended duct runs these one-acre-plus properties require. Every job gets camera-inspected before and after, with footage shown to the homeowner. No claims, just proof.
Calls are answered by a live person 24 hours a day - not voicemail, not an app. Most repairs are completed in a single visit. Our 90-Day Done Right Promise covers every job in writing: if it’s not right, we return at no charge with no paperwork required.

Our Duct Repair & Sealing Services in Southwest Ranches
Duct Sealing
Air leaks in Southwest Ranches ductwork waste 20-30% of conditioned air on average, and in these sprawling ranch homes with 80-120 linear feet of duct per air handler, that adds up fast. We seal with mastic compound and fiberglass mesh at every joint, boot, and penetration, then pressure-test to verify. In Southwest Ranches, we use heavier-grade mastic formulations because standard products degrade prematurely under the constant humidity and organic particulate load from adjacent horse operations. A typical whole-system sealing job here runs $450-$780.

Flex Duct Repair
Flex duct is common in Southwest Ranches attic spaces, and it’s uniquely vulnerable here. Hay bales stored above ceiling joists crush flexible runs. Raccoons and roof rats - drawn by the agricultural environment - tear the insulation jacket. We replace damaged sections with new flex or upgrade to rigid metal where the application allows. Flex duct repair in Southwest Ranches typically costs $280-$520 per run depending on length and attic accessibility. We recently tackled a job on River Run Road in Southwest Ranches where a ranch-style home’s flex-duct had been crushed by stored hay bales, causing collapsed sections and mold growth. We replaced the damaged flex duct with rigid metal, sealed all joints with mastic, and re-insulated the runs to handle the high-humidity environment abutting the Everglades.

Metal Duct Repair
Original metal ductwork in Southwest Ranches homes from the 1980s and 1990s is showing its age. Galvanized seams corrode faster here due to airborne ammonia from horse manure - a chemical stressor essentially absent in neighboring Weston or Pembroke Pines. We cut out corroded sections, fabricate replacement trunk lines on-site, and seal with two-part epoxy mastic for chemical resistance. Metal duct repair in Southwest Ranches ranges from $380-$650 for sectional replacement, or $890-$1,400 for full trunk-line rebuilds in larger homes.

Duct Insulation
With Southwest Ranches sitting on the western edge of Broward County directly abutting Everglades conservation areas, attic temperatures spike and condensation forms on uninsulated metal. We install foil-faced fiberglass or closed-cell foam insulation at R-6 to R-8 values, depending on your system’s location. Proper insulation here prevents the mold recurrence that standard suburban sealing jobs rarely face. Duct insulation in Southwest Ranches runs $2.80-$4.50 per linear foot.

Trusted Brands We Service in Southwest Ranches
We stock parts and specify equipment from Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors use, not discount-house generics. For Southwest Ranches homeowners, this means faster turnaround because we’re not ordering specialty fittings after the fact. Our Nikro duct cameras document every job. Honeywell zone dampers integrate cleanly with the multi-air-handler systems common in these larger estates. Aprilaire media filters handle the elevated particulate load from hay dust and organic matter better than standard one-inch pleated filters. We carry these items on our trucks, so most Southwest Ranches repairs don’t require a return visit.
Common Duct Repair & Sealing Problems We See in Southwest Ranches Homes
- Crushed flex-duct from hay bales or equipment stored in attic spaces. Southwest Ranches homeowners often use attic storage for farm equipment or seasonal hay, and flex duct routed between joists collapses under weight that suburban attics never see. Restricted airflow strains the air handler and drives up electric bills.
- Mastic sealant degrading prematurely due to constant high humidity and organic particulates. Standard mastic formulas rated for 10-year life in Pembroke Pines may fail in 4-6 years here. We specify mold-resistant, high-solids compounds formulated for agricultural-adjacent environments.
- Metal duct seams corroding from exposure to airborne ammonia from horse manure. This is nearly unique to Southwest Ranches in Broward County. Ammonia vapor accelerates galvanic corrosion at sheet-metal joints, creating pinhole leaks that standard smoke-pencil testing misses until energy bills spike.
- Mold harborage in extended duct runs that never fully dry. With AC running 10-11 months annually and ambient humidity from the Everglades, biological growth establishes in low-velocity sections and flex-duct corrugations. Camera inspection reveals what homeowners can’t smell yet.

FAQs - Duct Repair & Sealing in Southwest Ranches
Metal ductwork lasts longer and performs better in Southwest Ranches conditions, but full replacement isn’t always necessary. If your flex duct is intact and properly supported, sealing and re-insulating may suffice for $450-$620. If it’s crushed, rodent-damaged, or mold-saturated - common here due to attic storage and humidity - we typically recommend rigid metal replacement at $340-$520 per run. We’ll show you camera footage and let you decide. Call (844) 685-6342 for a free inspection.
It shortens standard mastic life by roughly half. Hay dust and manure particulates introduce organic nutrients and mild acidity that degrade conventional sealants faster than in urban Broward County homes. We compensate with high-solids, mold-resistant mastic formulations and more frequent inspection intervals. The 90-Day Done Right Promise covers any seal failure regardless of cause.
Yes, always. Sealing over hay fibers, manure dust, or active mold colonies traps contamination and accelerates degradation of the new seal. We camera-inspect first, then clean with HEPA-contained negative-air equipment before applying mastic. Combined clean-and-seal packages in Southwest Ranches run $680-$1,100 for typical single-system homes. Call (844) 685-6342 to schedule both services together.
It helps, but sealing alone rarely eliminates odor if your return-air grille draws directly from paddock-adjacent exterior walls. Sealing prevents attic and crawl-space odors from entering the supply stream, and it stops pressure imbalances that pull unfiltered outdoor air through gaps. For persistent equine odor, we typically recommend sealing plus a media filtration upgrade with Aprilaire cabinets rated for agricultural particulate loads. We’ll assess your specific intake placement and give you honest guidance on what sealing can and can’t do.
Yes, and we do so regularly in Southwest Ranches. We cut out corroded sections, fabricate replacement segments from 26- or 24-gauge galvanized steel, and seal with two-part epoxy mastic formulated for ammonia resistance. Sectional repair runs $380-$650. If corrosion exceeds roughly 30% of trunk-line length, we’ll recommend full replacement and show you why on camera. Either way, you’ll know the cost before we start - no surprises on the bill.
