What do Oklahoma code rules require for air duct sealing in Tulsa?
The Oklahoma Residential Code requires ductwork, air-handling units, return air boxes, and filter boxes to be sealed. Plenums, start collars, coil connections, Y's, and supply boot inner-liners must use liquid-applied or mastic sealants. Ducts outside conditioned space must be insulated to at least R-8 for ducts 3 inches and larger, and R-6 for smaller ducts.
How much duct leakage is allowed in Tulsa homes?
Oklahoma code requires ducts to be tested and verified at total leakage of no more than 4 cfm per 100 square feet, or 3 cfm if the air handler is not installed. State weatherization guidance also sets a target of 1 Pascal per register when measured with a pressure pan. Ask the pro for these test results.
Can I get a rebate for air duct sealing in Tulsa?
PSO rebate listings for Tulsa and eastern Oklahoma include duct sealing through the Power Forward program, listed at up to $300 on one page and up to $200 on another. OG&E advertises up to $300 for duct and/or air sealing. Some Oklahoma rebates are closed and return in 2027, so check availability each program year.
Why does attic insulation matter for ducts in Tulsa?
Oklahoma guidance requires accessible attics to be insulated to R-49 or to capacity if less. Hot attics make duct leakage and heat gain bigger problems. Supply ducts in attics must be sealed and insulated to a minimum of R-8, and uninsulated ducts outside the thermal boundary should be insulated to R-8, or R-12 if exposed to the exterior.
What to do next
- Ask the pro to run a duct leakage test and show results at or under 4 cfm per 100 square feet.
- Request a quote that lists sealing with mastic and insulation levels of R-8 or R-6 by duct size.
- Check current PSO Power Forward and OG&E rebate amounts before booking, since some rebates return in 2027.
