Fast, Reliable Duct Repair & Sealing Across Manor
Duct repair and sealing in Manor typically costs $180–$650 depending on whether you need spot sealing, full flex duct replacement, or attic insulation upgrades, and most jobs are completed same-day. If your HVAC runs constantly but rooms stay unevenly heated, or your energy bills keep climbing through Manor’s brutal summers, the problem is usually leaking ductwork—not your actual AC unit. We drive out to Manor regularly from our Houston base, and we know the 78653 area well enough to spot the patterns: builder-grade flex ducts in Shadowglen, attic air handlers baking in 140°F heat, and systems that have never been touched since the original installation crew packed up. Call (844) 886-2161 for a free estimate—Michael Brown, our owner and lead technician, handles every job personally.

Why Summit Air Duct Cleaning Service Texas Is Manor’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Manor on showing up and doing the work ourselves—no subcontracted crews, no bait-and-switch. Michael Brown, our owner, is the lead technician on every Duct Repair & Sealing call, which means you get the decision-maker diagnosing your system, not a trainee with a clipboard.
Our numbers back this up: 775 verified customer reviews averaging 4.9 stars. That volume rules out cherry-picking. Eight years focused exclusively on air duct and HVAC cleaning—this isn’t a side service we bolted onto carpet cleaning or general HVAC work.
We carry contractor-grade equipment: Rotobrush and Nikro systems, the same tools commercial restoration contractors use, not the consumer-grade shop vacs some competitors bring. For Manor homeowners, this matters because the fine black clay dust from the surrounding Blackland Prairie requires serious suction and sealed containment—not a Home Depot rental.
We also understand Manor’s growth timeline. Most of your neighbors moved into homes built between 2005 and 2023, and many of those systems have never been professionally serviced. We know the subdivisions, the builder patterns, and the specific failure modes that show up in tract homes on slab-on-grade foundations.
Our Duct Repair & Sealing Services in Manor
Duct Sealing
Manor’s attic temperatures regularly exceed 130°F in July and August, and every unsealed joint in your ductwork is dumping conditioned air into that inferno while pulling hot, dusty attic air back into your living space. We seal supply and return plenums, trunk line connections, and register boots using mastic sealant and fiberglass mesh—materials rated for the thermal cycling your Manor attic experiences. A typical duct sealing job in Manor runs $280–$450 for a single-system home. Most Shadowglen and Whisper Valley residents see immediate temperature balancing and 15–25% energy savings.
Flex Duct Repair
Builder-grade flex duct is the weak link in most Manor homes. The plastic inner liner tears at sharp bends, the insulation sleeve slides off, and the wire helix collapses under foot traffic during attic work. In Manor’s newer subdivisions, we’ve found entire flex duct runs hanging disconnected—blowing conditioned air straight into the attic while the homeowner cranks the thermostat lower and lower. Flex duct repair in Manor typically costs $180–$340 per run, including proper support strapping and insulation restoration. We recently sealed and insulated a flex duct system in a 2021-built home in Shadowglen. The homeowner noticed rooms were unevenly heated and cooling bills were high. We found multiple disconnected flex ducts in the attic—typical of builder-grade installations—and sealed them with mastic, restoring proper airflow and improving energy efficiency by 18%.
Metal Duct Repair
While most Manor inventory is newer flex-duct construction, we do encounter metal ductwork in some early-2000s builds and custom homes near downtown Manor. Metal ducts suffer from seam separation, rust at condensate points, and vibration fatigue at hanger locations. We repair with sheet metal patches, drive cleats, and high-temperature sealants—not duct tape, which degrades in months. Metal duct repair in Manor runs $320–$650 depending on accessibility and extent of corrosion.
Duct Insulation
Manor’s attic air handlers push 55°F air through ducts sitting in 130°F ambient temperatures. Without proper insulation, you’re losing 20–30% of your cooling capacity before it reaches the register. Worse, cold ducts in hot attics sweat, creating moisture that breeds mold and attracts pests. We install R-6 or R-8 fiberglass duct insulation with vapor barriers, properly lapped and sealed at all seams. Duct insulation in Manor costs $450–$780 for a typical 2,000-square-foot home. For homes in Whisper Valley still surrounded by active construction, this also helps block the fine concrete and clay dust that gets pulled into attic spaces through soffit vents.

Trusted Brands We Service in Manor
We stock parts and use products from Honeywell, Aprilaire, and Guardsman on every Manor job—not because we have to, but because we’ve seen what survives Central Texas attic conditions. Honeywell media air cleaners integrate well with the Trane and Carrier systems common in Shadowglen builds. Aprilaire humidistats and dehumidification controls help manage the moisture swings Manor sees between cedar fever season and summer’s bone-dry blast. We keep common flex duct diameters, mastic, and insulation on the truck so we’re not making a supply run while your attic hangs open. Fast turnaround matters when it’s 98°F outside and your system is hemorrhaging cooled air into the attic.
Common Duct Repair & Sealing Problems We See in Manor Homes
- Disconnected flex ducts at attic transitions. Builder-grade installations in Manor’s 2015–2023 housing stock often use minimal support straps. Thermal expansion and contraction through our 100°F summer temperature swings loosen connections within 3–5 years. We find fully separated ducts blowing nothing but attic air.
- Missing or compressed duct insulation. In Manor’s slab-on-grade homes with attic air handlers, installers sometimes skip insulation at hard-to-reach trunk lines or compress it to fit tight spaces. That R-value disappears, and the duct becomes a condensation surface during humid mornings.
- Construction debris contamination in “new” systems. In Manor’s actively developing subdivisions, a home that is five years old may still be surrounded by lots under construction, meaning residents face a continuous influx of concrete dust, disturbed clay soil, and lumber debris pulled into their HVAC systems throughout the neighborhood’s multi-year build-out—a contamination cycle that doesn’t exist in fully built-out Austin suburbs to the west.
- Leaky return air pathways pulling garage or attic air. Many Manor tract homes have return chases built from wall studs and drywall rather than sealed ductwork. These leak at every electrical box and framing gap, pressurizing your system with unfiltered air from the garage or attic.

FAQs — Duct Repair & Sealing in Manor
Because builder crews install ductwork quickly during construction, and quality control is minimal. In Manor’s master-planned neighborhoods like Shadowglen and Whisper Valley, the majority of homes were built during active construction phases, meaning their ductwork often contains construction debris such as drywall dust, insulation fibers, and clay soil that has never been professionally cleaned. Beyond contamination, we’ve found disconnected flex ducts, unsealed plenum connections, and missing insulation in homes less than three years old. The house is new. The ductwork installation quality often isn’t. Call (844) 886-2161 for a free inspection—estimates cost nothing.
Manor attic temperatures regularly reach 130–145°F in summer, which accelerates flex duct deterioration and makes every leak exponentially more costly. When 55°F conditioned air escapes into a 140°F attic, your system runs longer, works harder, and still can’t keep up. Uninsulated or poorly insulated metal ducts sweat in these conditions, creating moisture damage and mold risk. We size insulation and sealing approaches specifically for this thermal load. For a specific assessment of your attic setup, call (844) 886-2161.
Probably yes—especially if you’ve never had it inspected. In Whisper Valley’s still-developing environment, nearby construction continues to introduce dust and debris into your ductwork, contaminating the system even after initial cleaning. Beyond that, 2019 builder-grade flex duct connections are now five years into thermal cycling, and we’ve found significant leakage in homes with no obvious symptoms. Your system may be “fine” in the sense that it runs, but it could be consuming 20–30% more energy than necessary while circulating unfiltered attic air. A pressure test and visual inspection will tell the real story. Call (844) 886-2161 to schedule with Michael Brown.
Fiberglass duct insulation with a reinforced foil or vinyl vapor barrier, rated R-6 minimum and R-8 preferred for Manor’s extreme attic temperatures. We avoid bubble-wrap or reflective-only products—they don’t provide sufficient R-value for the thermal load here. The vapor barrier is critical because cold ducts in hot, humid attics sweat profusely; without it, you’re growing mold inside your insulation within two summers. We install with proper lap sealing at all longitudinal seams and end joints. For a quote on duct insulation for your specific home, call (844) 886-2161.
Yes, though most Manor inventory is newer flex-duct construction. We encounter metal ductwork in some early-2000s builds and custom homes, and we repair with proper sheet metal techniques—patching, drive cleats, and high-temperature sealants—not tape or caulk shortcuts. Metal duct repair in older Manor homes typically runs $320–$650 depending on accessibility and rust extent. Michael Brown will assess whether repair or section replacement makes more sense for your system. Call (844) 886-2161 to schedule.
