East Coast Vent’s assiduous staffers clear homes' circulatory systems of dust and debris with heavy-duty equipment and cleaning services for ventilation ducts and arterial passageways. The expert technicians arrive at doorsteps wielding a Ruwac vacuum, which employs a HEPA filter to siphon away allergens from dryer vents and air ducts. They can also install UV lights inside the HVAC duct to annihilate burgeoning swarms of bacteria, and they can swap out quickly deteriorating heat-system filters for permanent electrostatic filters designed to purify air indefinitely. After ensuring untainted lungfuls, the team unleashes FDA- and EPA-approved cleansers on sullied baseboards, undoing unsightly scuff marks and erasing condiment stains left from ketchup-packet hockey.
