A pressure test with telltale fog will keep your duct installers on their toes.
Airtight ductwork is one of the keys to a quality heating and cooling system. It helps to make a home more healthful, more comfortable, and more energy efficient. By reducing the load on the equipment, it also reduces wear and tear.
There is only one way to make sure that the ductwork has been thoroughly sealed: Test it. A simple pressure test can measure the airtightness of the air distribution system and helps you hold your installers to a high standard of quality.
