Leaky ductwork is one of the most common and most overlooked reasons an HVAC system runs constantly but never quite gets the house comfortable. In Central Oklahoma, I see it all the time: 20-year-old duct systems with unsealed joints losing 25 to 30 percent of conditioned air into attics and crawl spaces. You’re paying to heat and cool the attic. I fix that.
What Air Duct Sealing Involves
I locate leaks visually and with airflow testing, then seal them with mastic sealant and foil-backed tape, the proper materials that last the life of the duct system. Mastic doesn’t crack, peel, or fail in Oklahoma’s heat the way standard duct tape does. Joints, connections, boots at registers, air handler connections, all of it gets sealed.

Signs Your Ducts Are Leaking
- Rooms that never cool down in summer even when the AC runs all day
- High utility bills relative to your square footage and system age
- Dusty house even with regular filter changes, attic dust getting pulled in through leaks
- Uneven temperatures between rooms on the same zone
- System runs constantly but can’t reach setpoint
- Visible gaps or disconnected flex duct in attic or crawl space
Want to see it on a real job? My crew sealed and supported the duct in a Kingfisher attic that was pulling air out of the attic instead of the house. That job and two more are on video on my real ductwork jobs page.
What Duct Sealing Costs in Oklahoma
Duct sealing pricing depends on system size and accessibility. Most residential duct sealing jobs run $300 to $800. If there’s significant ductwork damage or disconnected sections, repair costs are separate. I’ll give you a firm quote after assessing the system, no surprises.
Frequently Asked Questions
How much does duct sealing cost in Oklahoma?
Most residential duct sealing jobs run $300 to $800 depending on system size and how accessible the ductwork is. Disconnected sections or significant damage are priced separately as duct repair. I give a firm quote before starting any work.
How do I know if my ducts are leaking?
Rooms that won’t cool or heat properly, high utility bills, dusty air, and a system that runs constantly without reaching setpoint are all signs. The most common leak points are joints at the air handler, boot connections at registers, and flex duct connections in the attic.
Is duct tape OK for sealing ducts?
No. Standard duct tape fails within a few years in attic temperatures. It dries out, cracks, and falls off. Proper duct sealing uses UL 181-rated foil tape and mastic sealant, which bond permanently and handle Oklahoma’s temperature extremes.
How much energy can I save by sealing my ducts?
ENERGY STAR says that in a typical house, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. In Oklahoma’s hot summers where AC runs hard for 5 to 6 months, sealing that loss adds up. How much it saves you depends on your ducts and your bills, so I will look at your system and your bills and tell you what to expect.
Do you seal ducts in attics and crawl spaces?
Yes. I work in attics and crawl spaces throughout Central Oklahoma. Attic ductwork is the most common problem area, heat buildup in Oklahoma attics accelerates duct deterioration and leakage over time.
