Four Corners sits at the crossroads of four counties in Central Florida’s lake country, and the housing stock here is unique. Most homes were built in the 2000s and 2010s as stucco-over-frame tract homes, many later converted into 6- to 10-bedroom vacation rentals with oversized HVAC systems and long, branching duct runs. That layout gives dust, mold, and air leaks more places to hide, especially with summer humidity pushing past 90% and air conditioners running nearly year-round. We know the communities along U.S. 27, the rental corridors near Bellalago, and the seasonal rhythms that drive when property managers need us there.

Our Duct Repair & Sealing Services in Four Corners

Duct Sealing

Leaky ducts in Four Corners homes waste 20-30% of conditioned air on average, and in vacation rentals with constant occupancy, that waste adds up fast. We seal supply and return plenums, register boots, and junction points using mastic sealant and proper metal tape, not the failing duct tape shortcuts we’ve found in too many flipped properties. Every sealed joint is photographed for your records. A typical duct sealing job in Four Corners runs $280-$480 for a standard 3-4 bedroom home, and $450-$850 for larger multi-bedroom rentals with extended duct runs.

Flex Duct Repair

Flex duct gets damaged. In Four Corners vacation rentals, we’ve found torn flex joints from guests or maintenance crews storing luggage and equipment in attic spaces that were never designed for access. A single tear can dump conditioned air into a hot attic or garage, leaving bedrooms stuffy and guests complaining. We replace damaged flex sections with properly sized, insulated flex duct and secure connections with metal collars and mastic. Flex duct repair in Four Corners typically runs $180-$340 per damaged section, including materials and labor.

Metal Duct Repair

Older metal ductwork in Four Corners homes, particularly in original construction from the early 2000s, can separate at seams or corrode in humid attic conditions. We reseal metal seams with mastic, replace rusted sections with galvanized steel, and reinforce hangers that have sagged under years of vibration. Metal duct repair in Four Corners generally runs $320-$650 depending on accessibility and the extent of corrosion.

Duct Insulation

Uninsulated or degraded duct insulation in Four Corners attics creates condensation problems that are relentless from May through October. We install fresh fiberglass or closed-cell insulation wraps to maintain air temperature and prevent the moisture buildup that leads to mold. Duct insulation work in Four Corners typically costs $2.50-$4.00 per linear foot, with most residential jobs falling between $400 and $900.

Mastic Sealant

Mastic is our preferred sealing material in Four Corners, and for good reason. Unlike pressure-sensitive duct tape, which degrades in high humidity, properly applied mastic remains flexible and airtight for years. We use Abatement Technologies and Aprilaire-compatible mastic products rated for Florida’s climate. The key is surface preparation, which too many installers skip. In Four Corners’s humidity, mastic applied over dust or oil will fail. We clean every surface first. Mastic sealant application as a standalone service runs $250-$550 for most Four Corners homes.

Air Leak Repair

We locate duct leaks using pressure testing and infrared inspection, then repair them at the source rather than masking symptoms. In Four Corners rental properties, unsealed supply register boots are a frequent find, especially in homes where quick renovations never tightened collars. We seal these properly and document the before-and-after for your records.

Trusted Brands We Service in Four Corners

We carry parts and materials from Rotobrush, Abatement Technologies, Aprilaire, and Guardsman, the same brands serious HVAC contractors specify. For Four Corners customers, that means faster turnaround because we’re not ordering parts from across the state. Our trucks are stocked with flex duct in common diameters, mastic compound, metal collars, and insulation wraps suited to Central Florida’s conditions. When a property manager calls with a guest complaint and a checkout deadline, that inventory matters.

Common Duct Repair & Sealing Problems We See in Four Corners Homes

• Torn flex duct from attic storage. Vacation rental guests and maintenance crews in Four Corners frequently use attic pull-down stairs for luggage and equipment storage. Flex duct near these access points gets crushed or torn. We relocate vulnerable runs or protect them with rigid duct where possible.
• Mastic failure from poor surface prep. We’ve opened up ductwork in Four Corners homes where previous installers slapped mastic over dusty metal or oily residue. In this humidity, that seal lasted one season. We clean with degreaser and wire brush before application.
• Unsealed register boots in flipped properties. Homes converted to vacation rentals often had rushed renovations. The drywall collar around the register boot was never sealed to the duct, so conditioned air leaks into the wall cavity. We seal with mastic and foam, then photograph for compliance.
• Condensation damage from missing insulation. In Four Corners’s low-lying lake country, summer dew points stay high for months. Bare metal duct in an attic sweats continuously, rusting seams and saturating surrounding insulation. We replace damaged sections and install proper vapor barriers.

Air Duct Cleaning in Four Corners, Done the Old Craft Way

South Florida’s heat and humidity push your system hard year-round, and the salt air doesn’t do the housing stock any favors. We inspect every run with a camera before we touch it and after we’re done, so you see what we see. Named for the oldest air-moving tool there is, Bellows sends trained journeymen, not salesmen, to clear your dryer vent to code and clean your ducts to the collar. One honest price, shown before work starts. No surprises on the bill.
