Air Duct Repair Oklahoma | Hartzell’s Heat & Air

A disconnected flex duct in the attic, a crushed trunk line, or a boot that’s pulled away from the subfloor — these are the kind of problems that turn a perfectly good HVAC system into a money pit. I find the problem, fix it right, and your system works the way it was designed to.

Duct Repair vs. Full Duct Replacement

Not every duct problem requires replacing the whole system. A disconnected flex run or a damaged section can often be repaired for a fraction of full replacement cost. I’ll tell you honestly whether spot repair makes sense or whether the system is deteriorated enough that full replacement is the better long-term investment. I don’t work on commission — you get the honest answer.

Sheet Metal Fabrication

I do my own sheet metal work — custom transitions, supply plenums, return plenums, and duct modifications for system upgrades. If you’re getting a new furnace or air handler and the existing duct connections need modification, that’s included in the installation scope.


Frequently Asked Questions

How much does air duct repair cost in Oklahoma?

Simple repairs like reconnecting a disconnected flex duct run $150 to $300. More involved repairs — replacing a deteriorated duct section, fabricating a new transition, or fixing multiple problem areas — run $300 to $700 depending on scope. I quote it after the assessment.

How can I tell if a duct is disconnected?

Classic signs: one room or zone that gets almost no airflow while the system runs fine elsewhere. If you can access your attic safely and see a flex duct with an open end just hanging there, that’s it. Don’t run the system without getting it fixed — you’re conditioning your attic.

Can you repair metal ductwork?

Yes. I do sheet metal fabrication and repair — sheet metal duct is more durable long-term than flex duct, and I can fabricate custom pieces when standard fittings don’t fit the existing layout.

My house has rooms that barely get any airflow. Is that a duct problem?

Often yes, but not always. Disconnected flex, a crushed run, or a blocked return can cause it. So can a low-quality air handler or an undersized blower motor. The $111 diagnostic will identify which — airflow problems are one of the most common complaints I see in Central Oklahoma homes.
