Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Air duct cleaning in Liberty Lake typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit.

We’re Hollis Air Duct Cleaning, and our crews work Liberty Lake from scheduling through our Seattle office, dispatching technicians who understand the specific conditions these newer suburban homes present.

Why Liberty Lake Homes Are Different
Liberty Lake sits in the Spokane Valley with cold, snowy winters and hot, dry summers. Heating and cooling systems here run hard in both seasons, pulling dust, pollen, and fireplace smoke through ductwork year-round. The surrounding Greenacres area’s spring pollen load is a recurring local complaint, and that debris doesn’t simply pass through sealed systems, it accumulates.
The housing stock tells the bigger story. Most Liberty Lake homes went up in the 1990s and 2000s, the planned subdivisions around the golf course and the lake itself, plus newer custom builds and condos. These are tighter constructions with flexible duct runs and sealed, high-efficiency systems, not the leaky metal trunk lines found in Spokane’s mid-century neighborhoods. That efficiency is a double edge. Less infiltration means less fresh air, and debris that does enter stays put.
Here’s the local wrinkle our technicians see regularly: because many of these subdivisions sit on former orchard land and near the lake, fine dust and construction debris linger in ductwork even in 2000s-era homes. Most have been owned by the same families for two decades. The system looks modern on the outside, and homeowners rarely realize it has never been cleaned.
Our Main Liberty Lake Services
Liberty Lake homeowners call us for three core jobs. Each has its own page with detailed pricing, process, and local specifics.
Air Duct Cleaning in Liberty Lake
We clean the full supply and return network using a Rotobrush rotary brush system paired with negative-air extraction from Nikro. In Liberty Lake, this means dislodging the fine orchard dust and construction debris that settles in flexible duct runs, then pulling it out before it recirculates. The sealed systems here respond well to proper cleaning, airflow often improves measurably, and we photograph the before and after so you see what came out. Air Duct Cleaning in Liberty Lake covers our full process and exact pricing.

Dryer Vent Cleaning in Liberty Lake
Dryer vent cleaning runs from the appliance to exterior termination, removing lint buildup that restricts airflow and creates fire risk. Liberty Lake’s newer homes often have longer vent runs through finished walls, and second-home condos may see intermittent use that masks developing blockages. We use rotary brushes and high-velocity air tools, then verify flow with a meter. Dryer Vent Cleaning in Liberty Lake has full details.

Duct Sealing in Liberty Lake
Duct sealing closes leaks in the supply and return plenums, trunk lines, and branch connections using mastic and mechanical fasteners. Even sealed, high-efficiency Liberty Lake systems develop gaps at joints over time, especially where flexible duct meets rigid fittings. We pressure-test the system, locate leaks with smoke or theatrical fog, then seal and retest to confirm results. Duct Sealing in Liberty Lake explains when sealing beats replacement.
