I recently had some troubles with unusually high energy bills, unpleasant odors in the house, and frosty spots in several rooms. Although the gas furnace seemed to be running non stop, it couldn’t keep up with demand. When I hired an Heating, Ventilation, and A/C corporation for repair, she evaluated the system and informed me that the problem was holes in the duct system. These leaks were allowing the heated air to escape before it ever reached the supply vents. She suggested Aeroseal, which is a patented technology that targets leaks from the inside. The process involves pressurized air and polymer adhesive particles which stick to the edges of the leak, gradually build up and complete an effective seal. The Heating, Ventilation, and A/C corporation started by plugging the registers in the condo with foam. This would then force any air to escape by way of the holes in the air duct. She performed a pretest on the duct system to determine the extent of the problem, then began the sealing process. She clogged the a/c indoor coil, fan and gas furnace to prevent the sealant particles from entering the inner workings. Non-toxic, UL maintained and approved particles and air was injected into the duct system. The air is put under pressure, which keeps the particles moving and sends them out through the many holes. The entire procedure was controlled by the laptop and gave the ability to watch the results. After completion, the laptop gave an analysis and proof of success. There was no odor, mess or disfigure, and the whole process was handled within a couple of ninths.
