A Duct Blast Testing uses a calibrated fan to pressurize the duct system, and measure the airflow through the fan. Duct air tightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage and certify compliance with duct leakage standards in a buildings HVAC system.
Air flow measurement systems are designed to test and document the air tightness of forced air duct systems in both houses and light commercial buildings. The Duct Blaster fan is connected directly to the duct system in a house, typically at a central return, or at the air handler cabinet. With the remaining registers and grilles temporarily taped off, duct air tightness is measured by either pressurizing or depressurizing the duct system and precisely measuring the fan flow and duct pressure. Eco Energy’s professional staff can seal up the A/C duct work.
