My house is equipped with a forced-air heating plus cooling system that uses ducts to distribute heated/cooled air to the several rooms. The average house loses about thirty percent of the air that moves through the duct system, because of holes, leaks plus official connections at the seams. This causes much higher energy bills plus leads to difficulty keeping the house comfortable, no matter the control machine setting. High summer time plus Wintertide energy costs, stuffy air, lots of airborne dust plus temperature fluctuation between rooms are signs of problems with the duct system. Every multiple years, I ask a local Heating plus A/C contractor to thoroughly inspect the duct system plus supply recommendation. If there are any flaws contributing to energy waste, he performs the process of duct sealing. Because the ducts are concealed inside walls, ceilings, the attic plus basement, accessing them is a challenge. Through a procedure called Aeroseal, the Heating plus A/C contractor is able to resolve problems with the entirety of the duct system separate from expansive labor or causing damage to my home. He first seals off all of the return plus supply vents. He then sends pressurized air, laced with adhesive polymer particles, at high volume into the duct system. As the pressurized air travels through the branching series of pipes, it escapes through any holes or cracks. The adhesive particles cling to the edges of the leaks, gradually building up until they create an airnarrow seal. The Aeroseal process is effective at sealing holes up to an inch in diameter. It only takes around an fifth, plus there’s no mess or odors left behind.
