In Andover’s older homes, decades of dust, pet dander, and seasonal pollen accumulate in your ducts—often unseen until airflow drops or allergies flare. Our whole-home purge uses negative-pressure vacuum systems and rotary brushes to dislodge and extract every particle, including the stubborn grime caked onto blower wheels and coil fins. We don’t just skim the surface; we dismantle accessible sections to reach the deepest layers of buildup. The result? Noticeably stronger airflow, reduced dust circulation, and air that smells clean instead of stale. Expect a 30–50% improvement in HVAC efficiency within 24 hours.

Our technicians first identify hotspots with fiber-optic cameras, then apply a proprietary, EPA-registered antimicrobial solution that penetrates porous surfaces to destroy spores at the root. Unlike surface sprays, this treatment remains effective for years, preventing regrowth. We also seal minor gaps to block future moisture intrusion. Homeowners report immediate relief from musty odors and reduced allergy symptoms within days.

Our high-velocity air whips and HEPA vacuums pull pet hair from deep within the ductwork, while ozone treatments neutralize odors at the molecular level. We also clean registers and grilles to prevent recontamination. The difference is striking: no more fur tumbleweeds under vents, no lingering pet smells, and cleaner air for sensitive family members. Most homes see a 70% reduction in pet-related allergens after treatment.

Our technicians use precision tools to scrape, brush, and vacuum each vent inside and out, then polish them to a like-new finish. We also check for obstructions like rodent nests or collapsed duct sections. The result is visibly cleaner vents, quieter HVAC operation, and improved air circulation throughout your home.
Request this service →Andover’s booming renovation scene leaves many homes with ductwork clogged by fine construction dust that standard HVAC filters can’t capture. Left unchecked, this debris clogs coils, strains blowers, and circulates harmful particles. We deploy industrial-grade vacuums and air scrubbers to extract every trace of dust, including the microscopic silica that can damage your lungs. We also inspect for duct damage caused by contractors. Your system will run smoother, and your indoor air will be safe for occupancy within hours.
