AC ductwork replacement is one of the most overlooked but impactful HVAC investments a Texas homeowner can make. Leaky or deteriorating ducts can waste 20–30% of your cooled air — meaning you're paying to cool your attic, not your home.
Most Spring TX homes built before 2005 have original flex ductwork that is approaching or past its practical lifespan. Flex duct is designed to last 15–25 years — after that, insulation degrades, connections loosen, and leakage increases. The result is an HVAC system that works hard but delivers results well below its rated capacity.

| Work Type | Cost Range | Best For |
|---|---|---|
| Duct sealing (Aeroseal or mastic) | $300–$1,500 | Ducts in good condition with leaks at joints |
| Partial duct replacement (problem areas) | $500–$2,000 | Specific damaged or disconnected sections |
| Full flex duct replacement | $1,500–$5,000 | Homes with aging original ductwork |
| Full rigid sheet metal ductwork | $3,000–$8,000+ | Premium homes, highest performance |
Costs vary by home size, attic accessibility, duct layout complexity, and material choice. Spring TX pricing reflects 2026 market rates.
A duct leakage test (blower door test) quantifies exactly how much your ducts leak before you decide. This is a worthwhile investment before committing to either sealing or replacement.

"Another company quoted $4,200 for a compressor. Expo found a bad capacitor — total bill was $180. That's the kind of honesty that earns a customer for life."— Harmony, Spring TX
"Used the online estimator first, then booked an in-home estimate. No pressure, clear comparison of both Carrier options, install was perfect."— Klein area, 77388
AC ductwork replacement in Texas costs $1,500–$5,000 for full flex duct replacement in a typical Spring TX home. Rigid sheet metal runs $3,000–$8,000+. Partial replacement of problem sections costs $500–$2,000. Duct sealing without replacement runs $300–$1,500. Costs vary by home size, attic accessibility, and material choice.
Consider duct replacement when: ductwork is original to a pre-2000 home, flex duct insulation is deteriorating visibly, multiple disconnected sections exist, or rooms persistently fail to cool despite a properly functioning system. Homes with original ductwork approaching 25+ years old often benefit significantly from replacement.
Yes — significantly. The average Texas home loses 20–30% of cooled air through duct leaks before it reaches the living space. You're paying full electricity cost to cool air that goes into the attic. Duct sealing typically reduces energy bills by 15–25% in homes with significant leakage and pays for itself within 2–4 years.
Aeroseal is a pressurized duct sealing process where aerosolized sealant particles are blown into the duct system from the inside and adhere specifically to leak points. It can seal leaks that are inaccessible from the outside without duct replacement. Cost: $1,000–$2,000 for most Spring TX homes. Verified with before-and-after leakage measurements.
