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

We’ve worked in enough Tehaleh homes to know the patterns. The master-planned community’s phased construction means we’ve sealed ducts in Lennar, Pulte, and Richmond American floor plans from the original 2005 builds through the newest phases near Tehaleh Heights Parkway. Our technicians arrive uniformed and background-checked, following The Garrison Code on every job: arrive inside the window, price in writing, complete the work by the book, leave the site clean.

Tehaleh homeowners call us back because the 365-Day Done Right Promise is backed in writing, not just mentioned at the door. If a sealed joint fails or a mastic application cracks within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re never waiting through a voicemail loop when you’ve got a duct issue.

HVAC Duct Sealing in Tehaleh

HVAC Duct Sealing in Tehaleh addresses the specific problems created by builder-grade flex-duct systems installed during the community’s rapid build-out from the mid-2000s forward. These original trunk lines, boot connections, and plenum seams weren’t always sealed to today’s standards, and two decades of thermal cycling in the Cascade foothills climate have loosened tape adhesives and cracked mastic. We seal with professional-grade mastic and reinforced mesh, applied after pressurized testing locates every leak.

A typical whole-system duct sealing in Tehaleh runs $850 – $1,400 for single-family homes up to 3,500 square feet, with attached townhomes and smaller plans starting around $650. The price is written down before we touch anything, and it does not move at the door.

Pressure Testing Before Sealing

We pressurize your duct system and measure leakage in CFM25, the standard metric for duct tightness. In Tehaleh’s tight-building-envelope homes, even 10% leakage forces your heat pump or furnace to work harder, and with ECM blowers common in newer phases, that restriction shows up immediately in longer run times and higher bills.

Mastic vs. Tape in Damp Climates

Tehaleh’s wet winters destroy standard duct tape within a few seasons. We use water-based duct mastic rated for Pacific Northwest humidity, reinforced with fiberglass mesh at joints and boots. This outlasts any adhesive product in crawl spaces that stay damp six months of the year.

Duct Repair in Tehaleh

Duct Repair in Tehaleh often starts with a homeowner noticing one room that never reaches temperature, or a sudden spike in PSE bills after years of predictable costs. The master-planned community’s original flex-duct runs, installed quickly during mass construction, are now old enough to have developed sags, crushed sections at tight bends, and disconnected boots where tape has failed. We repair or replace damaged sections, reconnect boots with mechanical fasteners plus mastic, and restore proper airflow before sealing the entire system.

Most duct repairs in Tehaleh fall between $320 and $780, depending on accessibility and whether we’re repairing a single run or multiple compromised sections. Every repair receives the same written price guarantee and 365-Day Done Right Promise as our full sealing jobs.

Crushed Flex-Duct Restoration

Builders in Tehaleh’s early phases sometimes routed flex duct through tight stud bays and attic trusses with minimal clearance. Over years, the compression reduces airflow by 30% or more. We replace these restricted sections with properly supported duct sized to the original HVAC design.

Boot and Plenum Reconnection

The connection between your main trunk and individual room boots is a common failure point in Tehaleh homes. We find gaps where original tape has dried and fallen away, then reconnect with sheet-metal screws and a full mastic seal that won’t repeat the same failure.

Trusted Brands We Service in Tehaleh

Our equipment roster includes Rotobrush rotary brush systems for pre-sealing cleaning, Nikro negative-air machines for debris control during repair work, and filtration products from Aprilaire and Guardsman that we install when sealing reveals your system needs better particle capture. We stock common flex-duct diameters, mastic, and mechanical fasteners used in Tehaleh’s builder-standard systems, so most repairs don’t wait on parts. When your heat pump or furnace brand requires specific fittings, we source them fast rather than improvising with hardware-store substitutes.

Common Duct Sealing Problems We See in Tehaleh Homes

• Original construction debris in flex runs. Tehaleh homes built during the 2005 – 2010 rush often have flex ducts still shedding drywall dust and wood particulate from the build. This grit accelerates tape failure and creates leak paths at boot connections that sealing alone won’t fix without prior cleaning.
• Heat pump conversions on undersized ductwork. Many Tehaleh homeowners have switched to heat pumps with ECM variable-speed blowers, which move more air volume than older furnaces. The original duct sizing, adequate for 1990s-era gas furnaces, now shows restriction and leakage under higher static pressure.
• Damp crawl space conditions degrading tape. Located in the Cascade foothills, Tehaleh’s crawl spaces stay humid well into June. Standard foil tape adhesive breaks down in this environment, leaving boots and plenum seams hanging open by the time we arrive.
• Wildfire smoke ash infiltration through leaks. When smoke drifts west from eastern Washington fires, leaky return ducts in Tehaleh’s tight homes pull contaminated attic air directly into the HVAC stream. Sealing these pathways is the only way to maintain indoor air quality during smoke events.
