Real stories from recent Frosty's HVAC jobs in Irving, TX -- published straight from the field.
When our tech arrived on Brandon Ct in Irving, this family's system just wouldn't cool—and the culprit was a failed capacitor on the condenser. We swapped it out that same evening and had things running right by night's end, so the house could finally cool back down. Nothing beat...

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 ClubLeaky 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 Irving diagnostic calls, and what each one typically costs to fix.
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.
Leaky returns pull unfiltered attic air straight into your supply stream. Sealing at $350 per repair stops the contamination at the source.
20-30% duct leakage means 20-30% more AC runtime. Sealing bad connections typically cuts summer bills 15-25%. 3-5 year payback.
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.
Usually undersized returns or crimped supply runs choking airflow. Manometer test during diagnostic measures exact loss. Fix varies by cause.
Leaky ducts pull pollen, dust, and insulation fibers into your breathing air. Duct sealing is one of the highest-impact IAQ improvements we make.
Irving ductwork problems map directly to the city's seven decades of construction. Heritage District 1950s-1970s ranches and bungalows are the worst — original gray flex duct with taped joints that gave up 15-20 years ago in 140-160 degree attic heat. Smoke-test readings in those homes routinely hit 30-40% air leakage, meaning a third or more of the conditioned air you paid Oncor to cool or Atmos to heat never reaches a register. It leaks straight into the attic. Valley Ranch 1990s-2000s two-story homes have better materials but longer runs to second-floor bedrooms, and those long flex runs sag, kink, and crush against framing over time — restricting airflow to the rooms that need it most. Las Colinas luxury homes from every decade vary widely, but even the 1980s-1990s builds are now 30-40 years into their duct lifespan. Duct sealing is $350 per repair, duct replacement is $700 per run, and plenum replacement runs $1,200-$1,500.
The most common Irving ductwork complaint I hear is 'my upstairs bedrooms are 5-8 degrees hotter than downstairs.' In Valley Ranch two-story family homes, this is almost always a ductwork problem, not an equipment problem. The second-floor supply runs travel the longest distance from the attic-mounted air handler, and if the flex has sagged or kinked over 20+ years, those rooms starve for airflow while the first floor overcools. Static pressure measurements confirm it — healthy residential systems should run under 0.5 inches of water column at the blower, and most Irving homes we first visit are running 0.8-1.2 (way too high). Fixing the duct restores balance without buying a bigger system or adding zoning equipment. In Las Colinas townhomes and condos with closet-mounted air handlers, I see a different pattern: short but poorly sealed trunk lines through shared wall cavities that lose pressure at every connection.
Every ductwork job in Irving includes before-and-after static pressure readings — I measure what your blower is fighting against, fix the problem, then prove the improvement with numbers. We don't offer standalone duct insulation as a band-aid product. If ducts are deteriorated enough to need insulation attention, they need full replacement with modern R-8 insulated flex or R-6 insulated metal to manufacturer spec.

Deeper context on ductwork written by Omar Jacobo (EPA 608 #2396328).
Signs: rooms that never cool or heat evenly (especially upstairs in Valley Ranch two-stories), high summer or winter Oncor bills, visible dust at supply registers, musty smells when the system runs, or ducts visibly detached/torn in the attic. For Heritage District 1950s-1970s homes with original flex duct, full replacement ($700/run) is usually the right call. For newer Valley Ranch and Las Colinas homes, duct sealing ($350) often solves the airflow issue.
Duct sealing $350 flat ($297.50 for members), duct replacement $700 per run ($595 for members), plenum replacement $1,200-$1,500. Most Irving single-family homes have 8-14 supply runs plus returns, so a full replacement typically lands at $5,000-$10,000. Heritage District smaller ranches are at the lower end; Valley Ranch and Las Colinas larger homes at the higher end. Flat-rate quote before starting.
Almost certainly yes. Valley Ranch 1990s-2000s two-story homes have the longest duct runs from attic-mounted air handlers to second-floor bedrooms. After 20+ years, flex sags, kinks, and crushes against framing — starving upper rooms of airflow. A static pressure test confirms it. Fixing the duct ($700/run replacement or $350 sealing per connection) restores balance without buying bigger equipment.
Depends on the condition. If the duct material is intact but joints are leaking, sealing ($350 per repair, $297.50 for members) works well. If the flex duct itself is torn, crushed, or the inner liner has separated from the outer vapor barrier — common on Heritage District 1960s-1970s original installs — sealing won't fix it. We inspect first and give you the honest answer.
New equipment pushing air through deteriorated ductwork is like putting a V8 engine on flat tires. If your ducts leak 25-35% of conditioned air into the attic, your new 18 SEER2 system is only delivering 12-13 SEER2 worth of efficiency to your rooms. A static pressure test ($85 diagnostic, waived with repair) identifies duct restrictions and leaks. Fixing them makes your existing equipment perform the way it was designed to.
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 Las Colinas and Valley Ranch 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.
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 Las Colinas and Valley Ranch 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.
