My modern home is equipped with a forced-air heating and cooling system that uses ducts to distribute heated/cooled air to the multiple rooms. The average apartment loses about thirty percent of the air that moves through the duct system, because of holes, leaks and improper connections at the seams. This causes much higher yearly bills and leads to difficulty keeping the modern home comfortable, no matter the control device setting. High summer time and Wintertide yearly bills, stuffy air, lots of airborne dust and temperature fluctuation between rooms are signs of problems with the duct system. Every several years, I ask a local HVAC corporation to thoroughly inspect the duct system and provide 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 and basement, accessing them is a challenge. Through a procedure called Aeroseal, the HVAC corporation is able to resolve problems with the entirety of the duct system without extensive labor or causing damage to my home. He first seals off all of the return and 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 air slender seal. The Aeroseal process is effective at sealing holes up to an inch in diameter. It only takes around an hour, and there’s no mess or odors left behind.
