Air duct sealing is a critical way to ensure that the indoor air your family breathes is pure. As your heating, ventilation and air conditioning (HVAC) system runs day after day, it draws particles of dust, pollen and other allergens into the ductwork. These irritants build up over time and eventually begin leaking into your home environment through a number of gaps and openings in your system's air ducts. At Gunner Insulation, we offer state-of-the-art duct sealing services, using a patented process that allows us to seal metal ductwork, sealing ducts on cooling and heating systems and effectively preventing the dirt, dust and other debris from contaminating the living areas of your home.
