Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Sealing Across Cheval
Duct sealing in Cheval typically runs $450 – $950 for a whole-home job depending on zone count and access, and most sealing work is scheduled within a few days of your call. If your Cheval home has two or more HVAC zones and the upstairs never cools like the downstairs, the problem is often leaky flex-duct collars at the air handler, not the thermostat. Call Hollis Air Duct Cleaning at (361) 326-5060 for a free written estimate before any work starts.
We’ve worked inside enough homes along Cheval Boulevard and Royal Oaks to know the pattern. Homes here were built between the mid-1980s and mid-2000s, most with builder-grade mechanicals now 20 – 35 years old, and the air handlers sit in garages or second-floor mechanical closets because of deed restrictions and course-facing designs. That layout matters. A leak in a Cheval duct system doesn’t just waste energy. It pulls unmetered air from the garage or chase, pressurizes one zone against another, and leaves you with a second floor that never catches up. Our Duct Sealing in Cheval crews are dispatched from our South Florida office and know the community’s expectations: containment on the driveway, no dust visible from the fairway, and documentation that satisfies a seller closing on a golf-front home.

HVAC Duct Sealing in Cheval
HVAC Duct Sealing in Cheval is most often needed in homes built during the 1990s and early 2000s where builder-grade flex-duct collars at the air handler were never sealed with mastic at handover. Construction dust and drywall debris got pulled past those loose joints for years, and now the system leaks conditioned air into the garage or mechanical closet instead of pushing it to the registers. A typical whole-home sealing job in Cheval runs $450 – $750 for a single-zone system and $650 – $950 for homes with two or more zones, which covers most of the larger detached homes here. We price by the system, not by the vent, and we agree to the number in writing before we start.
When Sealing Beats Replacement
Not every leaky duct needs tearing out. In Cheval’s housing stock, the flex-duct itself is often intact. The failure is at the collar, the plenum connection, or a sag in a long run over finished living space. We run a camera first. If the duct is structurally sound, we seal it with mastic and mesh, rebalance the zones, and you’re done for a fraction of replacement cost. If the duct is crushed, kinked, or mold-damaged, we’ll tell you that too, and we’ll show you the photo.
Zone Rebalancing After Sealing
Cheval homes commonly have two or more HVAC zones. Seal a leak on one zone without checking the others and you can throw the whole system off. Our techs measure static pressure and airflow at each return and supply after the seal is set. The goal is even temperature split, not just “less leaky.” We don’t leave until the numbers match the design.
Duct Repair in Cheval
Duct Repair in Cheval addresses the physical damage that sealing alone won’t fix: crushed flex-duct from storage items in the garage, disconnected runs in second-floor mechanical closets, or sagging lines over finished ceilings that have pulled away from hangers. Repair costs in Cheval typically range from $280 – $550 for a single run replacement or reconnection, and $600 – $1,200 for more extensive work involving multiple zones or access through drywall. We always inspect with a camera before quoting, so the price reflects what we actually found, not what we guessed.
Garage and Mechanical Closet Access
Cheval’s deed-restricted designs put air handlers and duct chases where they’re hard to reach and easy to disturb. We lay down protection, contain our cutting and dust, and restore the space before we leave. The Garrison Code requires it. Your garage or closet should look like we were never there, except for the improved airflow.
Course-Visible Containment
On golf-front properties, our negative-air setup runs through the driveway or golf-cart path, visible from the fairway. We use contained exhaust and proper filtration so there’s no dust plume, no debris on the pavement, and no complaint from the HOA. Neighbors on Royal Oaks have seen our rigs. They’ve also seen us leave the site clean.
Trusted Brands We Service in Cheval
Hollis stocks parts and sealing materials for systems commonly found in Cheval homes, including filtration products from Honeywell and Aprilaire, negative-air equipment from Nikro, and rotary brush systems from Rotobrush. We don’t order parts after the fact and make you wait. Our vans carry mastic, mesh, flex-duct, collars, and hangers sized for the builder-grade mechanicals typical of 1990s-era Florida construction. That means most Cheval duct sealing and repair jobs finish in one visit, with no return trip for materials. If your system uses Guardsman or Abatement Technologies components, we service those too, and we source factory-spec replacements rather than universal-fit substitutes.
Common Duct Sealing Problems We See in Cheval Homes
- Unsealed flex-duct collars at handover. The builder connected the flex to the plenum with a zip tie and no mastic. Twenty years of Cheval humidity and near-constant AC operation later, that joint is leaking conditioned air into the garage or chase, pulling in dust and garage fumes with it.
- Zone imbalance after amateur sealing. A previous crew sealed the obvious leak but never checked static pressure across zones. Now the first floor over-cools while the second floor starves, and the system runs longer, not shorter. We measure before and after.
- Sagged flex-duct over finished living space. Long runs between the air handler in the garage and second-floor registers lose hanger support over time. The sag creates a low spot where condensation pools and mold starts. We re-hang, seal, and insulate.
- Return leaks pulling unmetered garage air. In Cheval’s common garage-located air handler configuration, a leak on the return side doesn’t just waste energy. It introduces unfiltered garage air, car exhaust, and stored chemical fumes into your breathing air. We find these with smoke testing and seal them completely.
Pricing for Duct Sealing in Cheval, FL
A typical duct sealing job in Cheval runs $450 – $950 for whole-home work, with most golf-course-area homes falling in the $650 – $850 range because of their two-plus-zone layouts. Single-zone townhomes near the community entrances usually land at the lower end. Duct repair, when needed, adds $280 – $550 per run for replacement or reconnection. What moves the price: number of zones, access difficulty (garage vs. second-floor closet), whether we need to open finished ceilings or walls, and if zone rebalancing is required after the seal.
We give one flat price per system, agreed in writing before we start. No per-vent pricing. No add-ons at the door. You’ll see before-and-after photos from inside your plenum and ducts, and you’ll get a written report documenting what was sealed and what the pressure readings showed. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Cheval
You’ll likely need both. In Cheval’s 1990s-era homes, the flex-duct collars at the air handler were rarely sealed with mastic at construction, so construction dust and drywall debris have been pulled past loose joints for decades. A cleaning removes the debris; sealing stops the leak that let it in. We inspect with a camera and quote each separately so you choose what’s needed. Call (361) 326-5060 for a free estimate.
The most common cause in Cheval is a leak at the air handler or in the flex-duct chase serving the second-floor zone, often combined with a first-floor zone that’s over-performing because it’s not losing pressure. Our techs measure airflow at each register and static pressure at the handler to find where the balance is broken, then seal and rebalance in the same visit. Call (361) 326-5060 to schedule diagnostics.
Yes. We use contained exhaust filtration on all negative-air equipment, and we position intake and exhaust hoses to avoid any visible dust plume. In Cheval’s deed-restricted, course-facing community, this isn’t optional for us. It’s standard procedure, and we’ve done it on dozens of driveways and golf-cart paths visible from Royal Oaks and Cheval Boulevard without incident.
Yes. Our sealing methods, materials, and post-job verification meet NADCA guidelines for residential duct systems. That includes proper surface prep before mastic application, mechanical fastening at all flex-duct connections, and documentation of before-and-after pressure readings. We don’t cut corners on access just because the air handler sits in a tight Cheval garage or second-floor closet.
Townhomes near the Cheval entrances usually have single-zone systems with shorter duct runs and easier attic or closet access, so sealing is simpler and pricing lands at the lower end of our range. Golf-front singles off Cheval Boulevard typically have two or more zones, longer flex-duct runs over finished space, and air handlers in garages or second-floor closets that require more careful containment and access work. The sealing principle is the same; the execution differs based on layout and HOA visibility.
