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