CACEA – Residential Duct Air Flow Measurement: Assessing Impact of Air Flow on ASHP Sizing
zoomDuct capacity is often a limiting factor in sizing retrofit heat pumps, and contractors often size heat pumps based on the existing air conditioner, resulting in under-sized equipment. A simple 15-minute test can provide definitive air flow capacity of a duct system, contributing to a proper sized heat pump and avoiding poor system performance—such as […]
