DUCT SEALING
Stop paying to cool the attic.
The average Phoenix-area home loses 25-40% of its conditioned air through duct leaks. We pressure-test, seal the system from the inside out, and back the work for ten years.

Do you have leaky ducts?
Four signs we look for on every audit. Tick the ones that sound like your house — we’ll show you, in real time, how likely your system is leaking.
How it works
We seal the leaks the air finds — not the ones we can see.
Aeroseal pressurizes your duct system, then injects a UL-tested vinyl acetate aerosol. The particles stay suspended in moving air; the only place they stop is at a leak — where they bond, accumulate, and close the gap from the inside.
01 / TEST
Pressurize
02 / SEAL
Inject
A heated aerosol of vinyl acetate polymer follows the moving air. It bonds only at gaps — never on the duct wall.
03 / VERIFY
Re-test
We pressure-test again and hand you a one-page report. Most homes land between 4–9% post-Aeroseal.
Lower bill. Cleaner air. A system that lasts.
Sealing ducts isn't a luxury upgrade. It's the highest-ROI envelope work in a desert house — usually paid back inside two summers.
Reduce energy consumption
Less leakage means your HVAC delivers what it conditions. AZ homeowners typically see a 25–30% drop in summer cooling cost the first month — and the curve never reverses.
Estimate my savingsCleaner indoor air
Leaky returns pull from your attic — fiberglass, dust, rodent debris, the dry desert grit your house was supposed to keep out. Seal the returns and your air starts where it should.
Book an air-quality testExtend HVAC system life
A system that doesn't have to overrun its duty cycle lasts the manufacturer-rated 15–20 years instead of failing at 9. The cheapest replacement is the one you didn't have to make.
Talk to a technicianOne crew. One day. One report.
No tearing into ceilings. No follow-up visits. We arrive in the morning, pressure-test before lunch, and leave a sealed system with a printed report.
Inspect
Visual walk of every accessible run — supply, return, plenum. We photograph what we find and shoot you the report before any equipment leaves the truck.
Pressure-test
Block the registers, pressurize the trunk, log CFM loss to two decimal places. This is the number every utility and federal rebate is measured against.
Aeroseal
Heated aerosol of UL-tested vinyl acetate. The particles only land where air is escaping. Your house is occupiable; the work zone is one mechanical closet.
Verify & warranty
Re-pressurize, re-measure, hand you a stamped before/after report and a 10-year manufacturer seal warranty. APS and SRP rebate paperwork filed for you.
Hand sealing only finds the leaks an installer can reach.
Most of your duct system runs through walls, soffits and floor cavities. A technician with a caulk gun gets the joints in the attic — and misses everything else. Aeroseal finds the leaks the moving air finds.
Modeled savings
What a leaky house actually costs you.
Drag the sliders. We use Phoenix climate data, the leakage rate we measure on most Mesa homes, and current APS rates.

Frequently asked
The honest answers, in plain English.
You probably won't know — most homeowners don't. The four giveaways are uneven room temperatures, rising bills with no other explanation, dust on supply registers within days of cleaning, and an HVAC that cycles constantly in July. We pressure-test for free; the number doesn't lie.
Most jobs are 4–6 hours, start to finish, on a single weekday. Larger or zoned systems may need a second crew or a return visit. You can stay in the house — we work out of the mechanical closet, not your living room.
Quite the opposite — it improves it. The sealant is a UL-tested water-based vinyl acetate, the same polymer family used in chewing gum and craft glue. There's a faint adhesive smell during application that clears within hours. Once cured, it's inert and odorless for the life of the duct.
40+ years in lab testing. We back it for 10 with a manufacturer warranty — the same length as a new condenser. Sealing is a one-time job. We don't ask you to re-up annually like a service contract.
Before, if you can. A tighter envelope cuts your load 20–35%. Sizing solar to that smaller load means a smaller, less expensive array for the same financial outcome. If solar is already on the roof, sealing still pays back fast — every kWh you don't burn is one you can sell back or push to the battery.
$1,200–$2,200 for a typical Mesa single-zone home, before rebates. APS and SRP each offer envelope rebates ($150–$400). The federal Energy Efficient Home Improvement Credit (25C) returns 30% of the after-rebate cost as a tax credit. Net out-of-pocket on most homes lands between $700 and $1,500.
One-time. Aeroseal is a structural change to the duct system, not a coating or a wrap. The polymer cures hard. We've re-tested homes 8 years post-Aeroseal that still measure within 1% of the day-of result.
