HVAC blower units, also known as fans, are responsible for circulating cooled air from your air conditioner through the ductwork and through your building. Without a properly functioning blower, your air conditioning system would be unable to distribute cool air effectively.

There are four main types of blower fans commonly used in HVAC equipment: propeller fans, centrifugal fans, vane-axial fans, and tube-axial fans. Each type has unique characteristics suited for different AC units.
