Trusted Duct Repair & Sealing for Orlando Homeowners
Duct repair and sealing in Orlando typically costs between $350 and $1,200 depending on the scope, and most jobs can be completed same-day when you call (877) 417-1643 by noon. With 20 years in the air duct trade, Charles Rodriguez personally handles every repair — from flex duct collapses in Belle Isle attics to metal seam failures in Conway’s older ranch homes — backed by 1,278 verified reviews at a 4.9-star average. We’re not a dispatch service sending whoever’s available; Charles shows up personally with professional-grade equipment from Rotobrush and Nikro to fix what’s actually broken instead of selling you duct replacement you don’t need.
Orlando’s subtropical climate punishes ductwork harder than most homeowners realize. Between May and October, your attic hits 140°F regularly, cooking flexible duct adhesive until it separates at the collar. During winter cold snaps — yes, Orlando gets them — metal ducts in unconditioned crawl spaces contract and expand at seams you’ve never inspected. We’ve seen Hunters Creek homes losing 30% of conditioned air through gaps the size of a pencil eraser, and Williamsburg condos where flex duct has literally detached from the plenum and is blowing $200 a month into the insulation. That’s money you can stop bleeding today.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that let your conditioned air escape before it reaches your rooms. In Orlando, we regularly find homes in Meadow Woods and Doctor Phillips where 20–30% of airflow never makes it past the attic — you’re paying to cool your insulation. Charles uses a two-step approach: first, a pressure-assisted smoke test to map every leak, then professional-grade mastic sealant rated for Florida’s humidity extremes, not the cheap foil tape that fails in 18 months.
Flex Duct Repair
Flex duct is the ribbed, insulated tubing common in Orlando homes built after 1985, and it’s where we see the most preventable failures. In Southchase and Orlovista, we regularly find flex duct that’s been crushed by storage boxes, chewed by roof rats, or separated at the collar because the zip tie corroded. Charles carries replacement flex duct in R-6 and R-8 insulation ratings — the higher R-value matters in Orlando attics — and rebuilds connections with mechanical fasteners and sealed collars that outlast the original installation.
Metal Duct Repair
Metal ductwork in older Orlando neighborhoods like Pine Castle and Oak Ridge was built to last, but 40–60 years of thermal cycling has loosened seams and corroded hangers. We don’t replace sound metal duct unless it’s structurally compromised; Charles reseams with Pittsburgh-lock precision, replaces failing dampers, and reinforces sagging runs with proper support spacing. Our Nikro equipment handles the metal particulate safely, and we finish with Abatement Technologies-grade sanitizing when rust or organic growth is present.
Duct Insulation
Insulation that’s soaked from Orlando’s driving rains, compressed by workmen, or simply degraded past its R-value is costing you every month. We see this constantly in Sky Lake homes where the original R-4 flex has compressed to R-2 effectiveness. Charles replaces insulation with properly sized, vapor-barrier-wrapped materials — we don’t just tape over the problem — and pays special attention to condensation-prone areas where Orlando’s 85% summer humidity meets 55°F supply air.
Mastic Sealant
Mastic is the brush-applied, fiber-reinforced sealant that professional duct technicians use instead of tape for permanent repairs. In Orlando’s heat, standard duct tape becomes brittle and fails; mastic remains flexible and is rated for 200°F+ attic temperatures. Charles applies mastic with a consistency that comes from two decades of practice — thick enough to bridge gaps, thin enough to penetrate seams — and we only use water-based, low-VOC formulations that don’t off-gas into your air stream.
Air Leak Repair
Air leaks are the silent killers of Orlando HVAC efficiency, and they’re rarely where homeowners expect. We find them at the return air platform in Williamsburg townhomes, at the filter rack in Conway ranches, and where additions were cobbled onto original duct systems in Doctor Phillips. Charles pressure-tests the entire system, marks every leak with a numbered flag, and repairs in priority order so you see immediate improvement in room-to-room temperature balance and utility bills.

Brands We Service for Duct Repair & Sealing
We’ve worked on duct systems connected to every major HVAC brand in Orlando, and we understand how each manufacturer’s airflow specifications affect repair strategy. For Aprilaire whole-home systems, we know their dehumidifier add-ons place extra static pressure demand on ductwork — we’ve repaired dozens of crushed flex runs in Belle Isle homes where the original installer didn’t account for the additional airflow resistance. Our Rotobrush inspection cameras let Charles verify that Aprilaire-connected ducts are delivering rated CFM after repair, not just “sealed enough.”
With Abatement Technologies and Guardsman air quality systems, duct integrity is even more critical — these units are pulling and pushing air through HEPA and activated carbon stages that won’t perform if your ducts are leaking unfiltered attic air. Charles has repaired and sealed ductwork for Orlando homeowners with severe allergy and asthma concerns, ensuring that the investment they made in premium IAQ equipment isn’t undermined by a $12 gap in the return trunk. Whether your system is connected to Aprilaire, Abatement Technologies, Guardsman, or any other make, we can assess, repair, and verify performance.
Signs You Need Duct Repair & Sealing Right Now
- Hot and cold spots that shuffle around your house. One week it’s the back bedroom in Meadow Woods, next week it’s the kitchen in Southchase — this isn’t your imagination, it’s duct pressure imbalance from leaks that open and close with temperature and humidity swings. Left unaddressed, your compressor works harder and fails sooner.
- Dust that returns within 48 hours of cleaning. If you’re wiping Orlando’s orange pollen off surfaces twice a week, your return duct may be pulling attic air through a gap — that “dust” is often insulation particulate and organic matter from your soffits. Duct sealing stops the source; more cleaning just treats the symptom.
- Utility bills that spike without rate increases. We’ve had Conway homeowners call us after OUC bills jumped $80–$140 month-over-month with no thermostat change. In nearly every case, Charles found a primary supply duct partially detached from the plenum, dumping conditioned air into the attic since the last inspection.
- Musty or chemical odors when the AC cycles on. Orlando’s humidity plus a leaky return duct equals mold spores and volatile organic compounds drawn from crawl spaces and wall cavities. This isn’t a filter problem — it’s a duct integrity problem that sanitizing alone won’t fix permanently.
- Whistling, rattling, or whooshing sounds from vents or walls. These aren’t “normal HVAC sounds” — they’re pressure differentials screaming through gaps. A whistle at the Hunters Creek bedroom vent often means the flex duct has separated upstream; the whoosh in your Orlovista hallway is frequently a damper that’s fallen partially closed and is forcing air through an unintended path.
Our Duct Repair & Sealing Process — Step by Step
- 1
System inspection and airflow mapping. Charles arrives with a Rotobrush video inspection system and digital manometer to measure static pressure at key points. We identify every register and return, note temperature differentials with an infrared gun, and document what we find with photos you’ll see before any work begins.
- 2
Pressure testing and leak detection. We temporarily seal all vents and pressurize the duct system with our Nikro equipment, then use non-toxic smoke to visualize leaks — the same method commercial contractors use for hospital-grade duct verification. In Orlando’s older homes, we often find 15–40 individual leak points the homeowner never knew existed.
- 3
Prioritized repair plan with upfront pricing. Charles explains what we found in plain language, ranks repairs by impact (sealing a primary trunk leak before a bedroom branch), and provides written pricing before any work starts. No “we’ll see how it goes” — you know exactly what duct repair and sealing in Orlando costs for your specific situation.
- 4
Professional repair and sealing execution. This is where 20 years of duct systems shows. Charles repairs flex duct with proper mechanical connections, seals metal seams with mastic and fiberglass mesh for structural reinforcement, replaces degraded insulation, and verifies every repair with a post-work pressure test. We don’t leave until the numbers prove the fix.
- 5
Performance verification and documentation. We re-measure airflow at each vent, compare before-and-after static pressure, and provide you with a summary report. For homes with Aprilaire or Abatement Technologies IAQ equipment, we verify that rated airflow is being maintained — because clean air, not just clean ducts, is the outcome you’re paying for.
How Much Does Duct Repair & Sealing Cost in Orlando?
Duct sealing for a typical 1,500–2,500 square foot Orlando home runs $450–$850 when we’re addressing accessible leaks in attics and crawl spaces. Flex duct repair — replacing a collapsed or damaged section — generally falls between $280 and $520 depending on length and insulation rating. Metal duct repair, which requires more labor for seam rebuilding and hanger replacement in older Pine Castle and Oak Ridge homes, typically ranges from $380 to $720 per section. Full-system duct insulation replacement in a larger Williamsburg or Doctor Phillips home can reach $1,000–$1,800, though we often phase this work based on priority.
Several factors move pricing within these ranges. Attic accessibility matters — a truss-framed Sky Lake attic with 18 inches of blown insulation takes longer to navigate than a scuttle-access space. The extent of contamination affects whether we recommend Abatement Technologies-grade sanitizing as part of the repair. And the age of your original ductwork determines whether we’re repairing or recommending strategic replacement — Charles will tell you honestly when a 1970s metal system has reached the point of diminishing returns.
To avoid overpaying, get at least one estimate that includes pressure-tested verification, not just visual inspection. We’ve corrected work from Orlando “duct sealers” who smeared mastic on the outside of insulation (which does nothing) or used un-rated tape that failed within a year. Our estimates are free, detailed, and include the post-repair pressure test that proves the job was done right. Call (877) 417-1643 — you’ll speak with Charles directly, and there’s no obligation.

Frequently Asked Questions — Duct Repair & Sealing in Orlando
Duct repair and sealing fixes the physical integrity of your duct system — closing leaks, reconnecting separated sections, replacing damaged insulation, and reinforcing failing seams — while duct cleaning removes accumulated dust and debris from inside intact ducts. In Orlando, we often recommend both: cleaning first so we can see the actual condition of the metal or flex, then repair and sealing to prevent recontamination and energy loss. If your ducts are leaking, cleaning alone is like washing a bucket with holes in it.
Most residential duct repair and sealing jobs in Orlando are completed in 3–6 hours, with larger homes or extensive metal duct rebuilds in older neighborhoods like Pine Castle occasionally extending to a full day. Charles works methodically — we don’t rush the pressure testing or verification steps that prove the repair holds. You’ll know the timeline before we start, and we protect your floors and furnishings while working.
Typical duct repair and sealing in Orlando ranges from $350 for a targeted flex duct repair to $1,200 for comprehensive sealing and insulation replacement in a larger home. The biggest variables are accessibility (attic height, crawl space clearance), the extent of damage, and whether we’re working with metal duct that requires more labor-intensive repair. Call (877) 417-1643 for a free estimate — Charles will give you exact pricing after inspection, not a ballpark that changes later.
