Pearland HVAC Repair — Leaky ducts waste 25-40% of your AC's output -- and spike your electricity bill every month. We find leaks, seal them, and restore your system's efficiency.
Leaky ducts waste 25-40% of your AC's output -- and spike your electricity bill every month. We find leaks, seal them, and restore your system's efficiency.
Free Diagnosis: (281) 905-2414Duct Leakage Testing: We pressurize your duct system and measure how much air is leaking. Most Pearland homes built before 2000 leak 25-35% of conditioned air.
Duct Sealing (Aeroseal): We inject Aeroseal -- a polymer sealant -- into the duct system from the inside, sealing all leaks simultaneously without opening walls. Reduces leakage by 90%+ in most systems.
Flex Duct Repair: Re-connect disconnected runs, repair torn insulation, and replace damaged sections of flexible ductwork in your Pearland attic.
Full Ductwork Replacement: When the existing system is beyond repair, we install new properly-sized duct systems with sealed mastic joints and full insulation.
Most Pearland homeowners save $80-$180/month on electricity after duct sealing, paying off the investment in 2-4 years.
The most reliable method is a duct blower door test -- we pressurize the system and measure leakage rate in CFM25. Signs you can observe yourself: hot/cold spots, high bills, dusty vents, or visible duct separation in the attic. We offer free attic inspections to Pearland homeowners.
Almost always yes for Pearland homeowners. Texas's hot climate means your AC runs 7-9 months per year. At $0.12/kWh and a leakage rate of 30%, the average 2,000 sq ft Pearland home wastes $120-$200/month on lost conditioned air. Duct sealing typically pays for itself in under 3 years.
Aeroseal duct sealing takes 4-6 hours for a full home. Spot repairs take 1-3 hours. Full ductwork replacement takes 1-2 days. We work in your attic while you stay comfortable in the house.

Pearland TX sits at sea level on the Texas Coastal Plain, with relative humidity averaging 75–82% year-round and summer attic temperatures regularly exceeding 140°F. This combination — heat plus humidity cycling — degrades ductwork faster than almost any other climate in the continental US.
Flex duct in Pearland attics faces repeated thermal expansion and contraction across 3,000+ cooling hours per year. The outer vapor barrier cracks over time, exposing the insulation to humid attic air. Once compromised, the insulation absorbs moisture, loses R-value, and can develop mold within the duct assembly itself.
The Pearland housing stock — much of it built in Shadow Creek Ranch, Silverlake, Pomona, and Meridiana between 2000 and 2020 — was often installed with longer flex duct runs serving larger footprints. These longer runs are more prone to sagging between support points, creating flow restrictions that show up as uneven temperatures and longer AC run times.
High humidity accelerates outer vapor barrier failure on flex duct. Once the outer layer cracks, the insulation fiberglass batting absorbs attic moisture, the inner liner can develop condensation-related mold, and the duct loses thermal performance — delivering warmer air in summer.
140°F attic temperatures cause flex duct's spiral wire helix and liner to expand significantly. Repeated heat cycling — thousands of times over 10–15 years — works on connections and mastic sealant, gradually opening gaps at boots, takeoffs, and splices that weren't designed to handle that range of movement.
Pearland's expansive clay soils cause homes to settle over time, which can shift duct support points and change the geometry of duct runs. Runs that were properly supported at installation may sag several inches over a decade, creating airflow restrictions that appear as hot rooms or high energy bills.
Pearland TX's warm, humid climate supports a robust rodent population. Rats and squirrels in attic spaces frequently damage flex duct — chewing through outer liners, nesting inside duct material, and disconnecting boot connections. Ductwork inspection should always include pest damage assessment.
Whether to repair sections or replace the system depends on age, damage extent, and access.
Duct system under 15 years old — isolated disconnection or crush — damage confined to 1–3 sections — rest of system tested sound — accessible connections in good condition. Targeted repair with mastic sealant and section replacement can restore performance to near-new levels cost-effectively.
System over 15–20 years old — widespread vapor barrier failure — multiple disconnections — significant mold inside ducts — rodent damage throughout — undersized duct runs. Full replacement often costs less over 5 years than repeated repair visits on a degraded system.
| Service | Typical Range | What's Included |
|---|---|---|
| Duct connection repair (1–2 points) | $150–$400 | Mastic re-seal at loose boot or takeoff connection |
| Whole-system mastic sealing | $400–$800 | All accessible connection points sealed with brush mastic |
| Flex duct section replacement | $200–$500 per run | Remove damaged section, install new insulated flex duct |
| Partial system replacement (half) | $1,500–$4,500 | Most damaged half replaced; all connections remade |
| Full ductwork system replacement | $3,500–$8,000 | All new flex duct, insulation, boots; Pearland home pricing |
