Duct Sealing Questions
Is duct sealing messy?
No. Duct sealing is minimally invasive: we access your ductwork through existing vents and connections, with no demolition or drywall removal required. We clean up all materials before leaving.
How long does duct sealing take?
Most projects are completed in one day depending on access.
How much can duct sealing save on energy bills in Las Vegas?
Leaky ducts can waste 20 to 30 percent of the conditioned air your HVAC system produces, often losing it into an unconditioned attic. Sealing those leaks keeps that air in your living space, so the system runs less to hold the same temperature and monthly bills drop. The Cooling Company starts with a free in-home assessment and pressure test, then seals accessible gaps with mastic and metal-backed tape rated for Las Vegas attic heat.

Schedule Free AssessmentHow do you prove the duct sealing actually worked?
We pressure-test your ducts before sealing, then retest after the work to confirm a measurable improvement in duct tightness. You see the before and after numbers and get documentation of the verified result, so the improvement is proven, not assumed. For hidden in-wall leaks that hand sealing cannot reach, The Cooling Company is verified for Aeroseal, an inside-out process that seals ducts without cutting into your walls.

Book a Duct AssessmentHow TCC Seals Your Ducts
Las Vegas homes face unique duct challenges: intense attic heat (160°F+) degrades duct joints and tape over time, and crawlspace temperature swings accelerate seal failures. Our 3-step process locates every leak, seals it with the right materials for desert conditions, and verifies the results before we leave.
- 1
Pressure Test to Locate Leaks
We pressurize your duct system and measure airflow loss across each zone. This pinpoints exactly where air is escaping, whether at joints in the attic, connections at registers, or flex duct transitions, before any sealant is applied.
- 2
Seal with Mastic Sealant and Metal-Backed Tape
We seal every accessible gap with mastic sealant (a water-based compound that remains flexible under temperature cycling) and metal-backed tape rated for high-temperature attic conditions. Standard duct tape is not used because it fails within 1–2 years in Las Vegas heat.
- 3
Retest to Verify the Seal
After sealing, we run a second pressure test to confirm measurable improvement in duct tightness. You see the before and after numbers. If any leak points remain accessible, we address them before closing up. You get documentation of the verified result.
