Duct Repair & Sealing
Duct repair and sealing
Leaky or crushed ducts in a hot attic can lose a large share of the cooled air before it reaches the rooms. Testing, sealing and insulating the ducts often fixes hot rooms better than a bigger AC.

Las Vegas attics can reach 150°F in summer. Flex ducts that sag, tear or come loose from their boots dump cold air into the attic and pull in hot, dusty air.
A duct leakage test finds how much air is lost. Sealing with mastic, reconnecting runs and adding insulation brings air back to the rooms.

Frequently asked questions
Why is my upstairs so hot in Las Vegas?
Heat rises, attic ducts gain heat, and upstairs returns are often undersized. Duct repairs, extra returns or zoning usually help more than lowering the thermostat.
How long do flex ducts last?
In hot attics, flex duct jackets and insulation can break down in 15–25 years.
