When thinking about air conditioning or heating your home, you probably don’t give much thought to one of the most vital parts of the HVAC system. The “V” in “HVAC,” which is ventilation. And for most homes—probably including yours—the ventilation system is made up of ducts constructed from sheet metal, flexible plastic and aluminum, and duct board.
In order for your home’s heating and cooling to work at peak efficiency and effectiveness, it must have a tightly sealed ventilation system. This is how air pressure is maintained for the proper deliver of cooled and heated air to the vents around the home, and it prevents the loss or gain of heat. If the ventilation system sustains damage or develops air leaks (something that’s unfortunately common), it will create major problems for comfort and energy use in your house.
