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.

Why Mercer Island Homes Are Different
Mercer Island housing stock runs heavily toward 1970s and 1980s builds, with a mix of new construction and a few mid-century originals still holding on. That matters for ductwork because older Mercer Island homes often carry galvanized steel ducts that have been collecting dust, pet dander, and construction debris for decades, while newer builds near the south end of the island tend to have flex duct that traps dust differently. The lake environment also plays a role: even a few blocks from the water, ambient humidity keeps dust slightly tackier, so it clings to duct walls more stubbornly than it does in drier neighborhoods east of the lake. Homes up on the steeper lots near Island Crest Way also tend to run their furnaces harder through the damp months from October through April, which means more air volume pushed through the same duct surfaces. That combination, older housing stock plus lake humidity plus longer heating seasons, means a Mercer Island duct cleaning has to be thorough in a way a quick truck-mounted shop-vac pass simply isn’t.
Our Main Mercer Island Services
These are the three jobs Mercer Island homeowners call us about most often. Each one has its own dedicated Mercer Island page with local pricing and what to expect, so start there.
Dryer Vent Cleaning in Mercer Island
Laundry rooms on Mercer Island often vent through roofs or out long side-wall runs, and in older homes those runs can stretch 15 to 25 feet with multiple elbows. Every bend collects lint, and on a humid lake-facing lot that lint cakes instead of blowing clear. We run a Rotobrush through the full run and capture what comes out with a Nikro HEPA vacuum, so nothing ends up in your laundry room. Dryer Vent Cleaning in Mercer Island covers local pricing and timeline in detail.
Air Duct Cleaning in Mercer Island
This is whole-home duct cleaning: supply and return lines for your furnace and central air, from the trunk line to the register. In Mercer Island homes with 1980s-era galvanized duct, we remove the debris that has been circulating since the house was wired for its first VCR. Abatement Technologies containment keeps the dust we loosen from entering your living space during the job. Air Duct Cleaning in Mercer Island walks through the process and what it costs here.
HVAC Cleaning in Mercer Island
HVAC cleaning on Mercer Island includes the furnace, the evaporator coil, the blower assembly, and the duct runs that connect them. On an island where furnaces see heavy use from late fall through early spring, coil buildup cuts airflow and makes the system work harder than it should. We clean the entire circulation path, not just the visible registers. HVAC Cleaning in Mercer Island has the full scope and local price ranges.

What pushes a Mercer Island price toward the top of those ranges is usually access: crawlspace duct runs, attic trunk lines with low clearance, or a dryer vent that exits through a steep roof pitch and needs a taller ladder setup. Whatever the quote ends up being, the number is written down and handed to you before a single register is pulled, and that number does not change at the door.
