While the furnace and the cooling system share responsibility for keeping a comfortable home, the air duct is always working. The heated and cooled air passes through this network of pipes before being introduced into the numerous rooms. If there are any holes, cracks or separations at the seams, the conditioned air is allowed to escape. The majority of air duct is responsible for approximately 30% of energy losses, and when the heated/cooled air fails to reach the intended endpoint, the condo isn’t as comfortable; Certain rooms might feel warm or chilly. This leads to higher or lower control component settings, forcing the furnace or cooling system to toil harder, run longer and consume more energy. Rising bi-weekly energy bills are an indication of leaky air duct. These same flaws in the ducts also draw in unconditioned air, humidity, fumes, dust and other contaminants get pulled into the program and circulated throughout the house. Concerns with indoor air pollen levels can often be blamed on the ducts. The solution is professional duct sealing. At one time, Heating, Ventilation plus A/C contractors needed to find each imperfection and manually seal them one by one. It was a time-consuming, labor-intensive and not overly effective process, then since the majority of ducts are often concealed inside walls and ceilings, the contractors had trouble accessing them, now, however, there is a duct sealing technology that tackles the problem from the inside. Highly pressurized air laced with adhesive polymer particles is pumped into the duct system. As the air escapes through the holes and cracks, the particles adhere to the edges, gradually build up and form an airtight seal.
