Last winter, I noticed some problems with the gas furnace.
It seemed to be running a lot more often plus longer than usual.
The gas furnace was struggling to keep up with the control unit setting plus the beach house felt chilly. There was a definite difference in temperature between the various rooms. I also had to dust plus vacuum more frequently. Because I am conscientious about air filter fluctuations plus scheduling professional repair in the fall, I was surprised by the complaints with the gas furnace. I called our typical Heating, Ventilation & A/C supplier plus explained our problems. He immediately suspected the air duct as the source of the problems. After completing a testing of airflow through the air duct, he determined that approximately 25% of the heated air was escaping through holes plus cracks at the seams. These same leaks were drawing in cold, dirty outdoor air plus spreading contaminants throughout the house. I had no idea how duct sealing could be completed separate from a major mess. The air duct is installed behind the walls plus ceilings. The supplier explained a fairly new technology called Aeroseal works to service leaks from the inside. He first sealed off the supply plus return registers. He then pumped highly pressurized air into the air duct. This air was laced with adhesive polymer particles that are non-toxic. As the air escaped through the holes in the ducts, those particles clung to the edges plus steadily built up to give an airslim seal. The whole process was completed within a couple of hours. It is guaranteed to last several years plus makes a large improvement in the comfort, cleanliness plus efficiency of the home.
