Leaky Ducts Are an Indoor Air Quality Problem
Per the EPA, indoor air is 2-5x more polluted than outdoor air — and leaky ducts are one of the main causes. Every crack, loose connection, and failed tape seal pulls unfiltered attic air (dust, pollen, insulation fibers, rodent droppings) directly into your supply stream. Sealing and replacing bad runs is one of the highest-impact IAQ improvements we make.

Join Frosty ClubWhat Are the Most Common Ductwork Problems in The Colony?
Leaky and undersized ducts are the single most-missed cause of comfort problems I see in DFW homes. Here's what we find most often on The Colony diagnostic calls, and what each one typically costs to fix.
Uneven temperatures room-to-room
Classic sign of leaky supply runs or a failing zone damper. $85 diagnostic pinpoints the exact run. Fix is usually 1-3 duct repairs at $350 each.
Dusty rooms (no matter how often you clean)
Leaky returns pull unfiltered attic air straight into your supply stream. Sealing at $350 per repair stops the contamination at the source.
Climbing energy bills every summer
20-30% duct leakage means 20-30% more AC runtime. Sealing bad connections typically cuts summer bills 15-25%. 3-5 year payback.
Musty smell when the system turns on
Condensation inside flex liner leads to mold growth. You can't clean mold out of fiberglass — the only fix is replacement at $700 per run.
Rooms that never cool or heat enough
Usually undersized returns or crimped supply runs choking airflow. Manometer test during diagnostic measures exact loss. Fix varies by cause.
Allergy or asthma symptoms worse indoors
Leaky ducts pull pollen, dust, and insulation fibers into your breathing air. Duct sealing is one of the highest-impact IAQ improvements we make.
Why Do The Colony Homeowners Trust Frosty's for Ductwork?
The Colony ductwork problems track the age and style of the neighborhood. In 1990s Indian Creek single-family homes, most of the original flex duct is now 25-30 years old — inner liners separated from the outer vapor barrier, mastic failed, and joint tape long gone in 140-160°F attic heat. I routinely pull smoke-test readings of 25-35% air leakage in Indian Creek attics, which means a third of the air your system conditions is dumping into the attic before it reaches a register. Energy.gov estimates that the average American home loses 20-30% of conditioned air through duct leaks — Indian Creek homes often exceed that. Duct sealing ($350, $297.50 for Frosty Club members) or duct replacement ($700 per run, $595 for members) fixes it, and the CoServ Electric bill drop is immediate.
Austin Ranch townhomes have a totally different issue. Shared-wall dense construction with tight mechanical closets means the duct runs are already undersized from the day they were built — designers packed as much floor space as possible and left minimal room for proper return air. Upstairs zones starve in summer and overheat in winter. We size duct runs using Manual D (the ACCA standard) and often have to add a supply run, upsize a return, or relocate the return to break the starve pattern. No amount of zoning dampers will fix a fundamentally undersized duct. Stewart Peninsula and Rivers Edge lakefront homes have their own twist: Lewisville Lake humidity condenses inside uninsulated or poorly insulated duct surfaces in the summer, and that moisture feeds mold growth — the EPA tracks Aspergillus, Penicillium, and Cladosporium as common DFW duct contaminants in humid environments.
Every ductwork job in The Colony includes a before-and-after static pressure reading — we measure what your blower is fighting against before we start and prove the improvement after we're done. Target on a healthy residential system is under 0.5 inches of water column; most Colony homes we first visit are running 0.8-1.2 (way too high).

What Do The Colony Homeowners Ask About Ductwork?
How Do I Know If My Ducts Need Replacing In The Colony?
Signs: rooms that never cool or heat evenly, high summer or winter bills, visible dust at supply registers, musty smells when the system runs, or ducts visibly detached/torn in the attic. For 1990s Indian Creek homes with original flex duct, full replacement ($700/run, $595 for Frosty Club members) is usually the right call. For Austin Ranch townhomes, duct resizing and sealing often solves the starve pattern.
How Much Does Duct Replacement Cost In The Colony?
Duct sealing $350 flat ($297.50 for members), duct replacement $700 per run ($595 for members), plenum replacement $1,200-$1,500. Most Colony homes have 8-14 supply runs plus returns, so a full replacement typically lands at $5,000-$10,000. We quote flat-rate before starting and include static pressure readings before and after.
Can You Seal My Existing Ductwork In The Colony Instead Of Replacing It?
Sometimes — depends on the condition. If the duct material is intact but joints are leaking, sealing ($350) works well. If the flex duct itself is torn, crushed, or the inner liner has separated from the outer vapor barrier — common in 1990s Indian Creek — sealing won't fix it. We inspect first and give you the honest answer: seal-worthy, replacement-required, or borderline.
Why Does My Austin Ranch Townhome Have Poor Airflow Upstairs?
Austin Ranch townhomes were built with tight mechanical closets and undersized duct runs to maximize floor space. The upstairs zone is almost always starved for return air. A Manual D duct sizing calculation identifies it, and the fix is usually adding a supply, upsizing a return, or relocating the return. Zoning dampers don't fix undersized ducts.
Are My Lakefront Ducts At Risk For Mold Near Lewisville Lake?
Yes — higher ambient humidity in Stewart Peninsula and Rivers Edge means cold supply duct surfaces sweat more in summer, and any condensation inside supply boots or register takeoffs feeds mold growth (Aspergillus, Penicillium, Cladosporium). We inspect supply boots during any service call and recommend boot replacement or full duct replacement when we see active mold, not just surface mildew. Call (469) 254-0548.
Will New Ductwork Help My Older R-22 System in Austin Ranch and Grandscape?
Yes — EPA 608 Universal cert #2396328 lets me legally recover, recycle, and recharge R-22 under federal regulations. R-22 production ended in 2020 under the Clean Air Act phase-out (EPA.gov), so it now runs $200 per pound installed. A typical Austin Ranch and Grandscape R-22 leak repair totals $650-$1,000: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $200/lb. Optional leak seal $350 — but it can void manufacturer warranties, so I only recommend it in specific cases. For systems past 12 years with major leaks, planning the transition to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer for DFW homeowners.
Should I Update Ductwork Before Replacing My R-410A System in Austin Ranch and Grandscape?
Yes — ductwork outlives 2-3 system replacements. R-410A new-equipment production ended Jan 2025 under the AIM Act (Energy.gov), so your next replacement will use R-454B or R-32. Sizing the Austin Ranch and Grandscape ductwork correctly now sets up the new system regardless of refrigerant. EPA 608 Universal cert #2396328 covers all refrigerant work. Read our R-410A phase-out explainer for DFW homeowners.
