Why Duct Sealing Matters for Utah Homes
If you live in Utah County, your HVAC system works overtime—hot, dry summers in Lehi, frigid winters in Provo. According to ENERGY STAR®, the average home loses 15–30 % of conditioned air through leaks in ducts and boots. Those gaps force your furnace or heat pump to run longer, spiking energy bills and shortening equipment life.
Traditional Duct Sealing 101
- Method: A technician crawls through attics and crawl-spaces, hand-applying mastic paste or foil tape to visible seams.
- Average cost in Utah: $600 – $1,200 for a 2,000 ft² home.1
- Typical leakage reduction: 10 – 30 %.
- Pros: Lower upfront price; good for easily accessible ducts.
- Cons: Misses hidden cracks; messy; payback often 7–10 years.
How Aeroseal Works
- Method: Your ducts are temporarily pressurized and a computer-controlled machine blows a nontoxic, water-based polymer mist that finds and seals leaks from the inside.
- Average cost in Utah: $1,500 – $2,500 for the same 2,000 ft² home.1
- Typical leakage reduction: 70 – 95 % in under 2 hours.2
- Pros: Reaches hidden joints, elbows, and boots; instant before/after test results; cuts HVAC runtime up to 30 %.
- Cons: Higher upfront price; requires certified equipment.

Utah County Case Study: From 31 % Leakage → 1.4 %
In a recent Aeroseal project in Orem, pre-test results showed 31 % duct leakage. After a 90-minute seal, leakage dropped to 1.4 %, saving the homeowner an estimated $46 per month on gas and electricity. The $1,900 job (minus a $300 Wattsmart® rebate) pays for itself in 34 months—less than three heating seasons.
Rebates, Tax Credits & Financing
Rocky Mountain Power currently offers Utah homeowners rebates up to $300 for qualifying duct sealing. Pair Aeroseal with an HVAC upgrade, and you may also be eligible for the federal 25C tax credit (30 % of project cost, max $1,200).
Long-Term ROI Beyond Energy Savings
- Comfort: Even temperatures in every room—no more roasting upstairs and freezing basement.
- HVAC lifespan: Lower runtime can add 3–5 years to a furnace or heat-pump.
- Air quality: Fewer attic pollutants and allergens drawn into supply lines.
- Noise: Tighter ducts mean quieter airflow.
Which Option Is Right for You?
If your ductwork is exposed (unfinished basement, open attic) and your leakage test shows <15 % loss, a traditional hand-seal may be all you need. But if you:
- See energy bills skyrocketing
- Feel big room-to-room temperature swings
- Have ducts buried in drywall or tight chases
Aeroseal will almost always deliver the fastest payback—and Diamond Ducts provides same-day before/after reports so you can prove the savings to yourself.
FAQs
How long does Aeroseal last?
Independent lab tests show the sealant lasting 40 years + with zero degradation.2
Is the sealant safe to breathe?
Yes. It’s a non-toxic vinyl acetate polymer also used in white school glue, and the odor dissipates in under 2 hours.
Can I combine Aeroseal with other energy upgrades?
Absolutely. Pairing Aeroseal with a free energy audit and added attic insulation maximizes your rebate stack.
