Jacksonville ductwork cleaning, sealing & repair
We've worked on ductwork cleaning, sealing & repair jobs across Jacksonville long enough to know what tends to break here, when, and why. We answer the phone, give you a real quote before any work starts, and bring the right tools the first time.
Scope of work
Most homes have leaky ducts losing 20-30% of conditioned air to attics and crawl spaces. Sealing the duct system is the highest-ROI HVAC improvement most homeowners can make.
We test ducts with a blower door + duct blaster, identify leaks, and seal them with mastic (better than tape long-term) or aeroseal injection.
Full duct replacement is rare — only on systems with collapsed flex-duct, severe pest damage, or major redesign needs. More common: targeted replacement of damaged sections plus sealing of the rest.
What it costs
Duct leak test (blower door + duct blaster) runs $260 – $415. Mastic duct sealing (whole house) runs $780 – $1,655. Aeroseal injection runs $1,290 – $2,575. Damaged duct section replacement runs $315 – $1,105. Full duct system redesign + replace runs $3,130 – $9,015.
