Last winter, I noticed some problems with the oil furnace.
It seemed to be running a lot more often plus longer than usual.
The heating plan was struggling to keep up with the control machine setting plus the home felt freezing. 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 swings plus scheduling professional maintenance in the fall, I was surprised by the complaints with the oil furnace. I called our respected Heating, Ventilation, plus A/C business plus explained our troubles. She immediately suspected the HVAC duct as the source of the troubles. After completing a testing of airflow through the HVAC duct, she 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 plan how duct sealing could be completed without a major mess. The HVAC duct is installed behind the walls plus ceilings. The business explained a fairly new technology called Aeroseal works to repair leaks from the inside. She first sealed off the supply plus return registers. She then pumped highly pressurized air into the HVAC 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 deliver an airtight seal. The whole process was completed within a couple of hours. It is guaranteed to last numerous years plus makes a immense improvement in the comfort, cleanliness plus efficiency of the home.
