Leaky, undersized, or poorly designed ductwork is one of the most common reasons a new AC system still doesn't cool the house properly. We install, repair, seal, and redesign ductwork across Phoenix — and we always show you before-and-after airflow measurements.

The typical Phoenix home loses 20–30% of its conditioned air through duct leaks before it ever reaches the living space. Sealing those leaks is often the single highest-return improvement you can make to your AC system's efficiency.

We use Aeroseal duct sealing technology for hard-to-access ductwork — it seals from the inside by injecting aerosol adhesive particles that bond to leak sites. For major runs, we install new flex duct or sheet metal with properly sized branches and sealed connections.

Every duct job ends with a blower door test or duct pressure test so you can see the actual improvement in numbers, not just feel it.

Phoenix Air Conditioning Pros serves Phoenix, Scottsdale, Mesa, Tempe, Chandler, Gilbert, and the entire Valley. Call us for a free, no-obligation quote — we respond fast.

Frequently asked questions

How do I know if my ductwork is leaking?
Signs include rooms that never cool properly, high energy bills, and dusty vents. A duct pressure test gives you definitive numbers — we offer this as a standalone service.
How much does duct repair cost?
Minor duct sealing runs $300–$800. Full ductwork replacement for a typical Phoenix home ranges from $2,500–$6,000 depending on the size and complexity of the system.
What is Aeroseal?
Aeroseal is a patented duct sealing technology that seals leaks from the inside. Pressurized air with adhesive particles is injected into the duct system, and the particles bond to the edges of leaks. It can seal gaps up to 5/8 inch without opening any walls.
Should I replace ductwork when I replace my AC?
It depends on the condition and age. Ductwork over 20 years old or with significant leakage is often worth replacing at the same time as the AC — labor costs overlap and you'll get the full benefit of the new system.
