How do I know if my Pearland home has leaky ductwork?

Signs of leaky ductwork in Pearland homes include: rooms that never cool down even with AC running, unusually high electricity bills, excessive dust on vents and furniture, inconsistent temperatures room to room, and an AC system that runs constantly without reaching setpoint. A duct leakage test can confirm the problem.

How much does ductwork repair cost in Pearland TX?

Ductwork repair in Pearland TX typically costs $300-$1,500 for minor repairs and sealing. Partial ductwork replacement runs $1,500-$4,000. Full ductwork replacement for a typical Pearland home (2,000 sq ft) costs $4,000-$9,000. Most repairs pay for themselves within 2-3 years in energy savings.

Should I repair or replace my ductwork in Pearland?

If your ducts are under 15 years old and only have minor leaks, sealing and repair is cost-effective. If ducts are original (20+ years), severely crushed, or have extensive mold growth, full replacement is often better long-term. We'll give you an honest recommendation after inspection.
