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 Arlington?
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 Arlington 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 ArlingtonHomeowners Trust Frosty's for Ductwork
Arlington ductwork problems track the age of the neighborhood, and central and north Arlington has some of the oldest residential ductwork I see anywhere in DFW. In Rush Creek, Dalworthington Gardens, and the streets around Division and Lamar — most homes are 1960s-80s with original gray flex duct and taped joints. The tape failed a decade ago in 140-160°F attic heat. Smoke-test readings in those homes routinely come back at 25-35% air leakage, which means a third of the air your system is heating or cooling is dumping straight into the attic before it ever reaches a register. Duct sealing ($350) or duct replacement ($700 per run) fixes it, and the Oncor bill drop is immediate.
South Arlington and Parkside homes (1990s-2010s 2-story builds) have a different problem: duct runs that are too long, too narrow, and undersized for the upstairs supply. That's why the upstairs is always 10°F hotter than the downstairs in summer and 10°F colder in winter — not a thermostat issue, not a refrigerant issue, an airflow issue. Arlington's slightly higher humidity makes it worse, because undersized returns let humidity build up in upstairs bedrooms even when the temperature reads okay. We size duct runs using Manual D (the ACCA standard) and often have to add a supply or upsize a return on the upstairs zone to actually balance the system. Zoning dampers won't fix a fundamentally undersized duct.
Every ductwork job in Arlington 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 older Arlington homes we first visit are running 0.8-1.2 (way too high, which means the blower is working harder and failing sooner). We don't offer duct insulation as a standalone product — if ducts are that deteriorated, they need full replacement, not a band-aid. Plenum replacement runs $1,200-$1,500. License TACLA126718E.

Ductwork FAQ for Arlington, TX
How do I know if my ducts need replacing in Arlington?
Signs: rooms that never heat or cool 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 1960s-80s Rush Creek and Dalworthington Gardens homes with original flex duct, full replacement ($700/run) is usually the right call. For newer south Arlington homes, duct sealing ($350) often solves the airflow issue.
How much does duct replacement cost in Arlington?
Duct sealing $350 flat ($297.50 for members), duct replacement $700 per run ($595 for members), plenum replacement $1,200-$1,500. Most Arlington homes have 8-14 supply runs plus returns, so a full replacement typically lands at $5,000-$10,000. Flat-rate quote before we start, with static pressure readings before and after.
Can you seal my existing ductwork in Arlington 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 (very common in older Arlington homes after 30+ years of attic heat), sealing won't fix it. We inspect first and give you the honest answer: seal-worthy, replacement-required, or borderline.
Why is my upstairs always hotter than my downstairs in my south Arlington home?
In 2-story Parkside and south Arlington homes, the most common cause is undersized upstairs supply ductwork — runs too narrow and too long to deliver the CFM the upstairs zone needs. Arlington's slightly higher humidity makes it feel worse than the temperature reading suggests. A Manual D duct sizing calculation identifies it, and the fix is usually adding a supply run or upsizing the return. Zoning dampers won't fix an airflow problem.
Do you insulate ductwork in Arlington?
We don't offer standalone duct insulation as a product. If ducts are deteriorated enough to need insulation attention, they need full replacement — we don't band-aid. Modern R-8 insulated flex or R-6 insulated metal is built to manufacturer spec and is what we install on every replacement job in Arlington.
