Why Bellows Air Duct & Vent Co. Is Alafaya’s Preferred Duct Repair & Sealing Company
We’ve worked in Alafaya long enough to recognize the building patterns without pulling a permit. The late-1980s apartment clusters near University Boulevard. The 1994-2005 townhome waves along Alafaya Trail built to house UCF’s exploding enrollment. The Orange County tracts just south of 408 with original metal trunk lines and flex-duct branches that are now pushing 30 years. That history matters when we’re tracing a duct failure - we know what was installed, what has failed before, and what parts we’ll need on the truck.
Our Alafaya customers call us back because we don’t bait-and-switch. The price we quote after camera inspection is the price on the invoice. Every repair carries our 90-Day Done Right Promise in writing - if it’s not right, we return at no charge, no paperwork, no arguing. Calls are answered by a live person 24 hours a day, not an app or voicemail tree. Our technicians are background-checked, uniformed, and equipped with professional-grade tools from Nikro and Honeywell - the same brands serious HVAC contractors specify for their own jobs.
Most Alafaya repairs are completed in a single visit. We don’t leave you waiting.
Our Duct Repair & Sealing Services in Alafaya
Duct Sealing
Sealing is often the most cost-effective repair we perform in Alafaya, especially in student rental properties where joints have loosened through years of vibration and thermal cycling. We use mastic sealant and metal-backed tape rated for Florida attic temperatures - not the cheap foil tape that peels off in six months. A typical duct sealing job in Alafaya runs $280-$480 for a partial system, or $550-$850 for full trunk-and-branch sealing. We seal every accessible joint, then verify with a pressure test and camera so you see the difference.
Flex Duct Repair
Flex duct is the weak link in most Alafaya homes built between 1988 and 2005. The plastic inner liner cracks. The fiberglass insulation compresses or gets wet. The wire helix corrodes in humid attics. We replace damaged sections with new R-6 or R-8 flex duct, support it properly to prevent sagging, and seal all connections with mastic. In Alafaya’s high-turnover rental market, we’ve found flex duct that has cycled through five, ten, sometimes fifteen tenants without service - each bringing pets, cooking habits, and deferred maintenance that loads the liner with debris. A typical flex duct repair in Alafaya costs $180-$340 per section, with most jobs requiring one to three sections.
Metal Duct Repair
Older Alafaya homes and some commercial buildings near the 408 corridor have galvanized steel trunk lines. These can rust through at seams, separate at slip joints, or rattle loose from hangers. We patch small holes with sheet metal and mastic, reseal joints, and reinforce sagging sections. Metal duct repair in Alafaya typically runs $320-$580 depending on accessibility and extent of corrosion. Where metal has failed extensively, we’ll tell you straight whether repair or replacement makes more sense - no upsell, just an honest assessment backed by camera footage.
Duct Insulation & Air Leak Repair
In Alafaya’s climate, uninsulated or poorly insulated ductwork in a 140-degree attic wastes enormous energy. We reinsulate with formaldehyde-free fiberglass wrap or closed-cell foam where appropriate, and we repair air leaks that dump conditioned air into spaces that don’t need it. Air leak repair combined with insulation work in Alafaya typically ranges from $380-$720. This is the repair that pays for itself fastest on your FPL bill.
We recently answered a no-heat call at a townhome complex on Woodbury Road near the UCF campus. The original 1994 flex-duct had disintegrated at a junction near the air handler, dumping cooled air into an uninsulated crawlspace. We patched the gap with mastic and a 14-inch flex sleeve - the tenant was back to comfortable within two hours. That’s the kind of fix we aim for on every Alafaya call.

Common Duct Repair & Sealing Problems We See in Alafaya Homes
- Sagging flex-duct from decades of Florida humidity and no support creates pinch points that restrict airflow and trap moisture. In Alafaya’s older student housing, we’ve found flex duct draped across attic joists like a hammock, compressed to half its diameter, with standing water in the low spot. That restricted airflow forces your AC to run longer, costs more, and breeds mold.
- Disconnected duct joints in 1990s student housing cause conditioned air to escape into attics or crawlspaces, spiking electric bills. We regularly find joints that have pulled apart at the collar, especially in properties near UCF where systems cycle on and off constantly. The air handler runs, but half the cooling never reaches the rooms.
- Fiberglass liner in original 2000-era flex-duct becomes a breeding ground for mold when uncooled attic heat accelerates condensation. Alafaya’s subtropical climate means attics hit extreme temperatures, and when cool air meets that heat through thin duct walls, condensation forms inside. Over years, the fiberglass liner saturates and microbial growth takes hold. Standard filter changes never reach this problem.
- Accumulated tenant debris in high-turnover rentals loads duct systems beyond their design capacity. In the apartment corridors just off Alafaya Trail near UCF’s main campus, we regularly encounter duct systems that have cycled through multiple student tenants - each bringing pets, cooking habits, and deferred maintenance - resulting in fiberglass liner saturated with pet dander, food particulates, and visible microbial growth that accumulated tenant-by-tenant with zero documented service history.

FAQs - Duct Repair & Sealing in Alafaya
High tenant turnover means systems run continuously without maintenance, and original flex-duct from the 1990s and 2000s was never designed for that workload. In Alafaya specifically, the combination of constant AC use, Florida humidity, and zero service history through multiple tenant cycles causes the plastic liner to crack, insulation to compress, and wire helix to corrode faster than in owner-occupied homes. If you’re a landlord near UCF, we recommend inspection between tenants - call (844) 685-6342 to schedule.
Yes, if the tear is in the outer insulation jacket and the inner liner is intact, mastic sealant is the correct repair and typically costs $180-$280 in Alafaya. If the inner liner is torn or the wire helix is broken, we replace the section instead - mastic on a failed structural component is a temporary patch that will reopen. We’ll show you the damage on camera and quote both options before we start.
Metal duct requires cutting, patching, and sealing with sheet metal screws and mastic - a slower, more rigid repair that runs $320-$580 in Alafaya. Flex duct replacement is faster and more common in local housing stock, but metal trunk lines in older properties near Winter Park and the 408 corridor need specialized tools and hardware. Our technicians carry both skill sets and will match the repair method to what’s actually in your walls.
Yes, and this is one of the most common calls we get in the 32826 ZIP code. We reattach the duct to the collar with mechanical fasteners and mastic sealant, then support the run properly to prevent future separation. Most reattachment jobs in Alafaya run $220-$380 and are completed in under two hours. We also inspect adjacent sections while we’re in the attic - disconnected joints often indicate systemic support failure.
We do not seal over active mold growth - sealing traps moisture and worsens the problem. We clean and treat the duct interior first, then repair or replace damaged sections and seal only clean, dry surfaces. In Alafaya’s humid climate, this two-step process is critical. Combined cleaning and repair typically runs $480-$850 depending on system size. Call (844) 685-6342 and we’ll assess whether your ducts need cleaning, repair, or both.
