Leaks in the ducts cause lots of problems

It was a time-consuming, labor-intensive and not overly effective process.

While the furnace and the air conditioner share responsibility for keeping a comfortable home, the ductwork is always working. The heated and cooled air passes through this network of pipes before being introduced into the various rooms. If there are any holes, cracks or separations at the seams, the conditioned air is allowed to escape. The majority of ductwork is responsible for approximately 30% of energy losses. When the heated/cooled air fails to reach the intended destination, the house isn’t as comfortable. Certain rooms might feel overheated or chilly. This leads to higher or lower thermostat settings, forcing the furnace or air conditioner to work harder, run longer and consume more energy. Rising monthly energy bills are an indication of leaky ductwork. These same flaws in the ducts also draw in unconditioned air. Humidity, fumes, dust and other contaminants get pulled into the system and circulated throughout the house. Concerns with indoor air quality can often be blamed on the ducts. The solution is professional duct sealing. At one time, HVAC 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. 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.
