Duct sealing in Phoenix
The average Valley attic duct system leaks a quarter of what you pay to cool — into a 150° attic. Sealing it is $1,850, and it is the cheapest capacity money buys.
After hours — the line is answered and the truck rolls for $149 dispatch. Regular scheduling reopens Monday at 7:00 AM.
Your ducts run through the worst room in the house
Phoenix ductwork lives in the attic, and a Phoenix attic in July holds 150°. Every leak on the supply side dumps air you paid to cool into that oven; every leak on the return side pulls attic air — and attic dust — into the system and through your filter budget. Twenty-five percent leakage is not the horror story number. It is the median for pre-2000 flex duct here.
We test first: a duct blaster reading before, a target after, both numbers on your invoice. Sealing is mastic and collar work at every joint we can reach and aerosol sealant through the runs we cannot. SRP pays up to $400 of it when the reduction verifies, and the verification is the same test we already ran.

When sealing is the wrong spend
Crushed flex, disconnected runs, or a 1980s duct board trunk that is shedding fiber — that is replacement, not sealant, and we price it per run so you can stage it. And if you are about to replace the whole system anyway, seal FIRST: the load drops, and sometimes the replacement drops half a ton with it. The order of operations is worth real money.

“Two companies quoted me a bigger AC for the back bedrooms. Sofia tested the ducts and found a supply line that had been blowing into the attic for years. $1,850 of sealing fixed what $12,000 of equipment would not have.”
Same price after hours.
