- Flex duct connections, securing and sealing flexible duct at collar joints.
- Post-seal verification, retesting airflow and pressure to confirm improvement.
What drives duct sealing needs in Las Vegas

- Energy bills that keep rising even after filter changes and tune-ups

Common Questions About Duct Sealing in Las Vegas
How do I know if my ducts need sealing?
Signs include rooms that are hard to cool, excessive dust near registers, higher-than-expected energy bills, and visible gaps at duct connections in accessible areas like attics or garages. A duct inspection with pressure testing gives definitive answers.
How long does duct sealing take?
Most duct sealing jobs take 3–6 hours depending on the number of leaks and accessibility. We test pressure before and after to confirm the improvement.
What type of sealant do you use?
We use mastic sealant and UL-listed metal-backed tape rated for high temperatures. Unlike standard duct tape, these materials maintain their seal through Las Vegas attic heat and years of thermal cycling.
Will duct sealing reduce my energy bill?
In most cases, yes. The U.S. Department of Energy estimates leaky ducts can waste 20–30% of conditioned air. Sealing those leaks keeps that air inside your home where it belongs.
Can you seal ducts during an HVAC installation?
Absolutely. Pairing duct sealing with new equipment ensures your upgraded system delivers full performance from day one. We recommend sealing any time equipment is replaced.
