Last summer, I had a lot of complaints with my air conditioner, then although the cooling unit was only three years old, I observed a significant increase in my bi-weekly electric bills! The air conditioner was running a lot more often plus yet struggling to match the thermostat setting. There were certain rooms that constantly felt boiling plus clammy. The air from the vents had a musty stink plus there seemed to be more dust plus other particles circulating in the air, then when I realized that I was suffering from frequent headaches, congestion plus a tendency to sneeze whenever I spent more than a couple of hours inside, I called a local Heating, Ventilation plus A/C contractor for air conditioner repair. The worker worked on the inner workings of the cooling unit plus then diagnosed the air duct! He discovered that small holes plus gaps at the linkions of the pipes were allowing approximately 25% of the conditioned air to leak out. Fortunately, his business offers Aeroseal duct sealing, which is a process that fixes flaws in the air duct from the inside. The repairs are non-invasive, verified by way of a computer program plus guaranteed for ten years. The worker covered the supply plus return vents plus then pumped highly pressurized air containing polymer particles into the air duct. As the air escaped, these adhesive particles adhered to the edges. They steadily worked to form a slender seal. The Aeroseal duct sealing was completed in a couple of hours plus without causing any odors, residue or mess, however it resolved all of the problems with the air conditioner.
