HVAC • Air Handlers, Exchangers

Air handling units condition and circulate air and are comprised of a metal box, a blower, a cooling or heating element, filter chambers and dampers.

 An air handler is a device used to condition and circulate air within a heating, ventilating, and air-condition (HVAC) unit. Air handlers are usually housed in large metal boxes that each contain a blower, heating and/or cooling elements, filter racks, sound attenuators, and dampers.Air handlers are referred to by many names. Terminal units represent small air handlers, which are comprised of only an air filter, coil, and blower. A makeup air unit (MAU) contains only outside air, rather than recirculated air; and a packaged unit (PU) or rooftop unit (RTU) is designed for outdoor use, typically on roofs.Leading manufacturers: Trane, Goodman, Rheem, Lennox, American Standard, Hydronic and York.
