I recently had some complications with unusually high energy bills, unpleasant smells in the house, plus chilly spots in many rooms. Although the furnace seemed to be running non stop, it couldn’t keep up with demand. When I hired an Heating, Ventilation & A/C supplier for repair, he checked the plan plus 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. He recommended Aeroseal, which is a patented technology that targets leaks from the inside. The process involves pressurized air plus polymer adhesive particles which stick to the edges of the leak, gradually build up plus complete an effective seal. The Heating, Ventilation & A/C supplier started by plugging the registers in the home with foam. This would then force any air to escape by way of the holes in the HVAC duct. He performed a pretest on the duct plan to determine the extent of the problem, then began the sealing process. He clogged the air conditioner indoor coil, fan plus furnace to prevent the sealant particles from entering the inner finally workings. Non-toxic, UL tested plus approved particles plus air was injected into the duct system. The air is put under pressure, which keeps the particles moving plus sends them out through the many holes. The entire procedure was controlled by the computer plus provided the ability to watch the results. After completion, the computer provided an analysis plus proof of success. There was no smell, mess or disfigure, plus the whole process was handled within a couple of hours.
