+0% versus the national baseline
Installed prices in Arizona track the national baseline. Permit fees are about 5% lower than the national average. Owner-builder allowed with an ROC exemption affidavit on an owner-occupied home.
Extreme cooling load makes HVAC sizing, duct location and roof reflectivity the highest-leverage decisions in the state; pool permitting also carries mandatory barrier inspection.

The formula
Cost = (sq ft x rate) + (runs x per-run cost) x access multiplier + permit
Duct replacement is priced mostly by labor hours. Tight crawlspaces and low attics can add 30–50% over an open, walkable space.

Frequently asked questions
How much does it cost to replace ductwork?
Whole-home duct replacement usually runs $3,500 to $12,000 in 2026, or roughly $2 to $4 per conditioned square foot.
Should I replace ducts with the HVAC system?
If ducts are over 20 years old, undersized or badly leaking, doing both at once saves labor and protects the new system's efficiency rating.
