Why Hollis Air Duct Cleaning Is Hobart’s Preferred Air Duct Cleaning Company

We’ve been in business since 2004 as part of the Garrison Partners family, and that longevity matters in a market where fly-by-night duct cleaners run coupon specials and disappear. Hobart homeowners recognize our vans because we’ve returned to the same neighborhoods year after year, especially along the river bend where post-flood cleanups keep us busy. Our technicians are background-checked and uniformed, and they operate under The Garrison Code: arrive inside the quoted window, price the job in writing before touching equipment, complete the work by the book, and leave the site clean. Every job carries the 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround. Our phones are answered by a live person 24 hours a day, seven days a week, because duct problems don’t wait for business hours, and neither should your call.

Residential Air Duct Cleaning in Hobart

Residential Air Duct Cleaning in Hobart means dealing with a housing stock that tells two stories: the early-1900s farmhouses with galvanized steel ductwork that has accumulated 80-plus years of dust and begun to rust through, and the 1970s-to-1990s tract homes whose flexible ducting has sagged, torn, or filled with construction debris the original builders never cleared. Our process starts with a video inspection so you see what we see. We then use a Rotobrush rotary brush system to agitate debris from duct walls, paired with a Nikro negative-air machine that pulls loosened material out of your home entirely rather than redistributing it. A typical full residential cleaning in Hobart runs $350 – $650 depending on system size, accessibility, and whether we find mold or flood sediment requiring additional sanitation.

Supply Duct Cleaning

Supply ducts push heated or cooled air into your rooms. In Hobart’s older homes, these lines often run through unconditioned crawl spaces where groundwater seepage corrodes metal and flexible ducting droops into standing water. We remove and clean each register, brush the full length of every supply branch, and verify airflow balance before we leave.

Return Duct Cleaning

Return ducts pull air back to your furnace. They collect the most debris because they act as the home’s intake. In Hobart properties near the Cedar River, we’ve found return plenums packed with river silt after flood events, choking airflow and forcing HVAC systems to run longer and harder.

Commercial Air Duct Cleaning in Hobart

Commercial Air Duct Cleaning in Hobart covers the small-office buildings along Maple Valley Highway, the agricultural supply facilities near the river, and the retail spaces that serve this unincorporated community. Commercial systems are larger, more complex, and subject to heavier loading from foot traffic, equipment exhaust, and in some cases, crop dust and grain particulate from nearby farming operations. We use Nikro negative-air machines with HEPA filtration and Abatement Technologies containment systems to clean without shutting down your business. A typical commercial job in Hobart ranges from $800 for a small office suite to $2,400 for larger facilities with multiple zones and rooftop units. Every commercial proposal is written and itemized before work begins.

Full System Cleaning

Our full system service covers supply trunks, return plenums, branch lines, and the air handler cabinet itself. For Hobart commercial clients, this is the only approach that satisfies insurance inspectors after a flood event and keeps your HVAC warranty valid with manufacturers like Honeywell and Aprilaire.

Video Inspection Documentation

We record before-and-after footage of your commercial ductwork. This documentation protects your facility manager if occupancy or health questions arise, and it gives you proof that the work was performed to standard, not merely promised.

Trusted Brands We Service in Hobart

Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use in hospitals and schools, not hardware-store attachments pushed through a shop vac. For Hobart customers, this means we can source replacement filters, media, and sealing components without waiting on cross-country shipping. If your system uses Honeywell electronic air cleaners or Aprilaire media filters, we stock the correct sizing and can install them during the same visit. We also handle Dryer Vent Cleaning in Hobart and Duct Sealing in Hobart using Guardsman-grade mastic and metal-backed tape that holds up in our damp climate.

Common Air Duct Cleaning Problems We See in Hobart Homes

• River silt infiltration after Cedar River flooding. Homes along the river bend take on foundation moisture that carries fine sediment into crawl space vents and up into ductwork. The first sign is usually a musty odor that doesn’t clear with standard air freshening. We see this annually in Hobart, rarely in neighboring cities on higher ground like Issaquah.
• Rust and corrosion in pre-1950 galvanized steel ducts. Hobart’s farmhouses were built with metal ductwork that has now seen a century of Pacific Northwest rainfall. The metal thins, flakes, and eventually fails, sending rust particles through your vents and reducing system efficiency by 20 percent or more.
• Mold growth in flexible ducting with trapped condensation. The 1970s and 1980s tract homes in Hobart used flexible ducting that sags over time, creating low spots where condensation pools. Our wet climate keeps those spots damp year-round, and mold follows within two to three seasons.
• Construction debris in never-cleaned newer systems. Even homes built in the 1990s often still contain drywall dust, wood shavings, and insulation scraps that builders left in the ducts. Hobart’s tighter building envelopes from that era trap those contaminants inside, recirculating them every time the furnace runs.
