What We Do
Air Duct Repair and Sealing in Las Vegas, NV
Small duct problems hide well. A joint that's come apart in the attic, a strap that let a run sag, a hole where a mouse got in: none of it is visible from the living room, but all of it costs you cool air every hour the AC runs.
We track down the actual failure points and repair them. Most fixes are targeted: reconnect, reseal, patch, re-support, re-insulate. If a section is too far gone to save, we'll tell you plainly, and only replace what has to be replaced.

Why It Matters
Why Duct Start Leaking in Las Vegas Desert
Heat and time attack the weakest points in a duct system first: the joints, seams, and connections. Here's what typically gives out.
Extreme Attic Heat
Summer attic temperatures bake duct adhesives and insulation, and seams slowly pull apart.
150°F+
typical summer attic temperature
Failing Tape
Cloth-backed duct tape often dries out and lets go within a few years in a hot attic. Mastic and foil tape hold.

Pest Entry
That's all a mouse needs. Once they chew through flex duct, it leaks air and pulls in debris.

Air Lost To Leaks
The share of airflow a typical leaky duct system can lose before it reaches your rooms.

Health & Savings
What a Leaky Duct System Is Actually Costing You
You won't see a leak from inside the house. You'll notice a room that won't cool, a bill that keeps climbing, and an AC that runs and runs.
Your Health
4°F+
Uneven Temperatures
A gap of 4°F or more between rooms usually points to leaking or disconnected runs. No thermostat setting fixes that; the duct has to be sealed.
110°F
AC That Never Shuts Off
On a 110°F day, air leaking into the attic keeps your system running nonstop, wearing it out years early.
Your Energy Bill
20-30%
Energy Wasted Monthly
Roughly the monthly cost of a 20–30% leak on a $300 summer bill. Sealing wins it back.
The Difference

✓ Problems fixed while they're still small
Warning Signs
Signs Your Air Duct Needs Repair
Ducts rarely fail all at once. Watch for these eight clues that something has come loose, torn, or worn out.
01
Hot or Cold Rooms
A room that lags behind the rest of the house usually has a leak or a disconnected run feeding it.
High Priority02
Rising Electric Bills
Same AC, same habits, higher bill? Air escaping into the attic is a common cause.
High Priority03
AC Running Nonstop
If the system can't reach the set temperature or cycles constantly, it may be losing air before it reaches your rooms.
High Priority04
Whistling or Hissing at the Vents
Air escaping through a gap or crack often makes a hiss or whistle you can hear near a register.
Moderate Priority05
Rattling or Banging Sounds
Loose sections, broken straps, or a duct shifting when the blower starts.
Moderate Priority06
Weak Airflow at Certain Vents
Hold a hand to the register. If airflow feels weak compared to other rooms, there's likely a leak or restriction upstream.
Urgent07
Visible Damage in the Attic or Crawlspace
Torn insulation, a disconnected boot, chew marks, or a sagging run should be fixed before they get worse.
Moderate Priority08
Excess Dust or Attic Odors Indoors
Leaks in return ducts pull attic dust and insulation fibers into your air. Dust that comes back quickly is a clue.

How Often Should Commercial Ductwork Be Inspected for Leaks?
Commercial systems run longer hours and move more air, so a small leak turns into a big energy loss fast. Regular inspection catches failures before they hit your equipment or your tenants.
