Last winter, I observed that the heater was starting up more often in addition to running for much longer cycles.
It seemed as if it was operating non stop, in addition to yet the house felt chilly.
There were inconsistent temperatures from one room to another. When I observed a significant increase in my weekly heating bill, I called an HVAC contractor for repairs. The serviceman took the heater apart, diagnosed all of the components in addition to tightened a few wires. He didn’t find anything worrisome. He then maintained the air duct in addition to discovered that approximately twenty-five percent of our heated air was escaping. These same holes in addition to cracks were allowing outside, unconditioned air to enter the house. Because the full amount of heated air produced by the heater was failing to reach the several rooms, the system was forced to work a lot harder in addition to use more energy. The duct system is largely concealed behind walls in addition to ceilings in addition to in the crawlspace. I distraught that fixing the concern would require a huge, messy in addition to invasive renovation project. Instead, the contractor explained a process called Aeroseal. This fairly recent innovation seals flaws in the air duct from the inside. The contractor first congested off all of the supply in addition to return registers. He then pumped highly pressurized air into the duct system. This air included adhesive polymer particles that are really non-toxic. As the air flowed out of the holes in addition to cracks, those particles steadily built up along the edges in addition to formed a slender seal. The Aeroseal process is guided by a computer program in addition to warrantied for ten years. It took a couple of hours to complete. The serviceman then repeated the duct testing in addition to proved the effectiveness of the results.
