Duct Pressure Testing

Duct pressure testing (or “duct leakage testing”) measures the amount of leakage in a duct system and air handler. At Eco Three, we primarily use this test in new construction homes to ensure the system meets Energy Code requirements. Before the test, we cover all registers/vents then attach our duct testing fan and manometer to a central return. Then we turn on the fan and depressurize to 25 pascals. The manometer measures the cubic feet per minute pulled through the system by the fan. The result is the number of cubic feet per minute at 25 pascals or CFM25. Duct leakage is calculated based on the square footage area that the system heats and cools. If a system exceeds the allowable leakage, we can pressurize the system and use a smoke pen to identify leaks.

Air Duct Sealing

In homes with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.

A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer. Contact us for a quote to seal the ducts in your home and improve the performance of your heating and cooling systems.

Air Duct Efficiency

If you are using a central air conditioning unit, make sure the air ducts are properly insulated, especially those that pass through the attic or any other areas that are not air-conditioned. You may want to have a specialist check for holes or leaks in the ducts once a year.

Air Duct Repair

Duct tape can offer a temporary repair, but eventually, holes and leaks will need to be professionally fixed. If you have rooms in your house that you don’t often use, such as a guest-bedroom, shut the doors and close the vents to save on energy.
