Why Titan Air Duct Cleaning Service Orlando Is Leesburg’s Preferred Duct Repair & Sealing Company
Charles Rodriguez shows up personally on every Leesburg job. He’s been working on duct systems for 20 years — longer than most competitors in Central Florida have been in business — and he’s the one who inspects, repairs, and seals your ducts, not a rotating crew you haven’t met.
That accountability shows in our numbers: 1,278 verified reviews averaging 4.9 stars. Leesburg homeowners in the retirement communities off U.S. 441 and the lakefront neighborhoods near South Lake Shore Drive have left detailed feedback specifically mentioning our response time and the fact that the owner handled their repair.
We carry professional-grade equipment from Rotobrush and Nikro, the same brands commercial contractors use, and we stock mastic sealant, foil-backed insulation, and replacement boots so we’re not making two trips. From the moment we cross into Lake County, we’re prepared for what Leesburg attics throw at us: 140°F temperatures, original 1970s metal ductwork, and the chronic condensation issues that lake humidity creates.
Our Duct Repair & Sealing Services in Leesburg
Duct Sealing
Leesburg’s near-continuous AC runtime — 10 to 12 months a year — forces air through every gap and seam in your duct system. We seal supply and return plenums, trunk lines, and branch connections with mastic sealant, not tape that dries and fails. In the older homes around Lake Griffin and Lake Harris, we frequently find original metal ducts that were never properly sealed at the fabrication stage; we brush mastic into every longitudinal seam and transverse joint, then pressure-test to confirm the fix. A typical duct sealing job in Leesburg runs $280–$450 for a single-system home.
Flex Duct Repair
The manufactured home communities in 34788 and some of the 1960s ranches in 34748 rely on flex duct that degrades faster than metal in Leesburg’s humid attics. We see kinked runs, collapsed sections, and disconnects at the plenum that rob bedrooms of airflow. Our Rotobrush camera inspection lets us locate hidden separations without tearing into drywall. We cut out damaged flex, install properly supported new runs with sealed collars, and verify airflow at the register before we leave. Flex duct repair in Leesburg typically ranges from $180–$340 per run.
Metal Duct Repair
Original metal ductwork in Leesburg’s retirement-community homes has been expanding and contracting for 40 to 60 years. Seams crack. Support hangers fail. Rust forms where condensation pools. Charles has repaired metal trunks in homes off South Lake Shore Drive where the original galvanized steel was paper-thin from decades of moisture exposure. We patch, replace sections, or transition to new metal where the old has failed, always sealing with mastic and adding insulation where the original barrier has degraded. Metal duct repair in Leesburg generally runs $320–$650 depending on linear footage.
Duct Insulation
Leesburg’s attic temperatures destroy duct insulation. The foil-facing on original wraps delaminates. Fibrous liners absorb moisture and collapse. We install new foil-backed insulation with proper vapor barriers, sized to prevent the sweating that leads to mold growth. In lakefront homes where humidity is measurably higher than in Orlando or Ocala, this step isn’t optional — it’s what keeps your repair from failing again in two seasons. Duct insulation work in Leesburg usually falls between $250–$480.

Trusted Brands We Service in Leesburg
We repair and seal duct systems connected to all major HVAC brands, and we stock parts and materials from Rotobrush, Nikro, and Guardsman for fast turnaround on Leesburg jobs. That means no waiting on shipments when your 34788 manufactured home needs a new flex collar or your lakefront ranch needs an insulated register boot. We also use Abatement Technologies-grade sanitizing products when biological growth is part of the problem — because clean air, not just clean ducts, is the outcome homeowners in Leesburg actually need.
Common Duct Repair & Sealing Problems We See in Leesburg Homes
- Sweating metal supply boots in lakefront homes. In neighborhoods off U.S. 441 near Lake Griffin, cool metal register boots sweat against humid attic air, creating chronic condensation traps. We replace these with insulated boots and seal with mastic to break the cycle.
- Degraded fiberglass-lined ductwork in 1960s–1980s retirement homes. Decades of biological buildup in original lined metal ducts can’t be cleaned out — the material is too far gone. We cut out affected sections and replace with sealed metal or properly supported flex.
- Kinked and disconnected flex duct in manufactured home communities. The 34788 ZIP has numerous mobile home parks where undersized flex runs separate at joints or sag into moisture-saturated insulation. Our camera inspection finds the break without destructive exploration.
- Failed mastic and tape at plenum connections. Leesburg’s heat-cycling forces expansion at the furnace or air handler plenum. Original sealant crumbles. We clean back to bare metal and reseal with fresh mastic rated for the temperature swings these attics see.

What moves you within these ranges? Accessibility matters: attics in Leesburg’s older ranches are often tight, and manufactured homes in 34788 may need us to work around existing structure. The extent of biological contamination affects whether we can seal in place or must remove and replace. And lake-humidity damage is often more extensive than homeowners realize — that condensation at the boot usually signals deeper issues upstream. We diagnose before we quote, and estimates are always free. Call (877) 417-1643.

FAQs — Duct Repair & Sealing in Leesburg
Yes — dripping registers indicate condensation on uninsulated metal supply boots, a chronic problem in Leesburg’s lake-humidity microclimate. We replace the bare metal boot with an insulated version and seal the connection with mastic to prevent warm, humid attic air from contacting cold metal. Call (877) 417-1643 for a free inspection — estimates are free.
Every two to three years, or immediately if you notice uneven cooling, musty odors, or rising energy bills. The original fiberglass-lined ductwork in these 1960s–1980s homes degrades predictably, and early inspection lets us spot separation or biological buildup before it spreads into your living space. Call (877) 417-1643 to schedule — estimates are free.
Very likely — undersized flex duct in 34788 manufactured home communities commonly kinks, sags, or disconnects at joints after years of vibration and humidity exposure. We use Rotobrush camera inspection to locate the exact restriction without cutting into walls or ceiling. Call (877) 417-1643 — we’ll diagnose and quote same-day, and estimates are free.
Yes — mastic is our standard for every metal-to-metal and metal-to-flex joint we touch. Tape fails in Leesburg’s attic heat; mastic remains flexible and airtight through thousands of temperature cycles. We apply it with brushes and gloves, working it into seams the way 20 years of duct work has taught us. Call (877) 417-1643 to see the difference — estimates are free.
We recommend Aprilaire media air cleaners for homes in Leesburg’s high-humidity zones — they handle the pollen load from live-oak canopy and the biological particulates that lake humidity promotes, without restricting airflow the way dense pleated filters can. We can assess your system’s capacity and install during the same visit as your duct repair. Call (877) 417-1643 — estimates are free.
