Everett’s four distinct seasons demand air systems that perform flawlessly year-round, and that’s where our white-glove process shines. We start with a pre-inspection crawl through your attic or basement, no surprises, then deploy truck-mounted negative air systems to capture 99.9% of contaminants before they ever reach your living room. Our HEPA-filtration vacuums and rotary brushes don’t just chase visible debris; they dismantle the invisible buildup of mold spores, pet dander, and construction dust that accumulates in Everett’s tightly sealed 20th-century homes. Each job concludes with a final walkthrough and a satisfaction guarantee you can feel, not just read.
Choosing Wong isn’t just about cleaner air; it’s about peace of mind. We back every cleaning with a 5-year workmanship warranty and provide certified before-and-after particle counts so you know the difference. Our technicians are background-checked, drug-tested, and trained to spot early signs of duct degradation, saving you costly repairs down the line. Whether you’re in the shadow of the Mystic River or tucked into the quiet streets of Woodlawn, we treat your home like our own: with respect, transparency, and a finish that lasts.
