Compressors, coils, fans and a heating section in one factory-built cabinet. Rooftop units are the most common form, but packaged equipment also sits on grade or indoors.
Packaged units may be cooling with gas heat, heat pumps, or water-cooled self-contained units connected to a condenser-water loop. Single-zone units vary temperature; multizone or packaged VAV units serve VAV terminals. Economizers, energy recovery and dehumidification options vary by product line. See the rooftop units guide for roof-mounted equipment and manufacturers.

Manufacturers design, build and test equipment. Distributors supply equipment, quotations, parts and order support. Manufacturer reps support selections, specifications and represented product lines; some also distribute. Categories overlap only where supported by official sources.
