Why Hollis Air Duct Cleaning Is Provo’s Preferred Duct Sealing Company

We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Provo was built one sealed joint at a time. Homeowners in neighborhoods like Grandview, Carterville, and the Riverbottoms know our technicians arrive uniformed, background-checked, and inside the quoted window, not “sometime between 8 and 5.”

Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. When you’re running your furnace nonstop through a January inversion and smelling something off from the vents, that matters.

We know Provo’s housing stock intimately. The galvanized steel ductwork in those 1950s – 1970s ranches near downtown and the university has been corroding for decades in hard-water humidity. Rust flakes break loose, joints separate, and the system starts pulling unconditioned air from wherever it can find it. Newer flex-duct homes on the east bench have different failure modes: kinks, compression at tight bends, and tape that dried out years ago. We diagnose before we quote, and we quote before we touch anything.

Duct Sealing Services in Provo

Duct Sealing Services in Provo address the leaks, gaps, and separated joints that waste energy and degrade air quality in Wasatch Front homes. A typical whole-home duct sealing job in Provo runs $450 – $1,200, with most homes between $650 and $950. Single-zone repairs or partial system sealing can run $180 – $450 depending on accessibility and the extent of deterioration. We use mastic compound and mechanical fasteners, not the hardware-store foil tape that peels off in three years, and we pressure-test after we finish to verify the seal.

Mastic Sealing for Rigid Metal Ducts

Older Provo homes with original galvanized steel trunk lines need brush-applied duct mastic, a fiber-reinforced compound that flexes with thermal expansion and won’t crack like tape. We access the plenum, trunk lines, and branch takeoffs, clean corrosion and old adhesive away, and apply two coats to every joint and seam. The result holds up to decades of furnace cycling.

Aeroseal for Inaccessible Leaks

When ducts run through finished walls or sealed soffits, we offer aerosolized sealant injection. The system pressurizes your ductwork, locates leaks with a computer, and seals them from the inside with a non-toxic polymer that bonds to the edges of gaps up to 5/8 inch. No drywall demolition, no mess, and we show you the before-and-after leakage numbers on screen.

Duct Insulation in Provo

Duct Insulation in Provo protects against the temperature swings that cost you money every month. Uninsulated or poorly insulated ducts in attics, crawlspaces, or garages lose 20 – 30% of conditioned air before it reaches your rooms. In Provo, where summer days hit the 90s and winter nights drop below 20°F, that loss hits your utility bill hard. Whole-home duct insulation typically runs $800 – $2,000 depending on linear footage and R-value needed, with partial retrofits starting around $400.

Fiberglass Wrap for Exposed Trunk Lines

We wrap rigid metal ducts with formaldehyde-free fiberglass insulation, secured with mechanical fasteners and a vapor barrier jacket. For Provo’s climate, R-6 to R-8 is standard; we calculate heat gain and loss through your specific attic or crawlspace and specify accordingly. No guesswork, no undersizing.

Foam Board for High-Loss Areas

Where ducts pass through unconditioned spaces with extreme temperature differentials, we use rigid foam board with sealed joints. It’s more expensive per foot than fiberglass wrap, but it stops thermal bridging at plenum connections and long straight runs where heat loss is most severe. We mark these locations during inspection and explain the tradeoff before you decide.

Trusted Brands We Service in Provo

Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration and sealing products from Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use in hospitals and schools, not hardware-store gear. For Provo homeowners, that means we stock parts and materials locally, so repairs and retrofits don’t wait on shipping. If your system uses Aprilaire media filters or Guardsman UV components, we match them exactly. No substitutions, no “this is just as good.” The Garrison Standard requires us to specify what we install, why it fits your system, and how long it lasts.

Common Duct Sealing Problems We See in Provo Homes

• Inversion soot degrading tape adhesives. After a hard winter inversion, we find ducts near Provo’s older core coated with a fine black film from PM2.5 that settled out of recirculated air. This residue breaks down the adhesive on foil tape and causes mastic to delaminate prematurely, requiring more aggressive surface prep than in cleaner-air markets.
• Galvanized corrosion at basement trunk lines. The calcareous hard water in Provo accelerates rust in galvanized steel components, especially where basement humidity collects at the main plenum. Pitted metal doesn’t hold sealant well; we often need to sister in new sections or transition to flexible duct at the damage point.
• Flex-duct kinks in east bench new construction. Tight framing in newer Provo homes forces 90-degree bends in flexible ducting that crush the inner liner and create turbulence points where dust accumulates. We reroute where possible and replace compressed sections rather than seal around the damage.
• Garage return-air leaks in split-level ranches. Many Provo homes from the 1960s and 1970s have return plenums that pass through or terminate in attached garages. A gap here pulls carbon monoxide, paint fumes, and gasoline vapor into your breathing air. We seal these with code-compliant hard duct and gaskets, not tape alone.
