If you’ve never heard of Aeroseal duct sealing, it is gaining popularity as a more effective and convenient method of safeguarding the condition of ductwork. After closing off the system’s grilles and registers, the trained specialists from Residential Heating and Cooling will introduce air containing aerosolized adhesive particles. As the air is blown in, it will speed up and turn sharply when forced through any leaks in the ductwork. The aerosolized particles deposit on the edges, building up and sealing holes as large as one inch across.
