SIC 3822 Automatic Controls for Regulating Residential and Commercial Environments and Appliances
SIC 3822
Establishments in this industry are primarily engaged in manufacturing temperature and related controls for heating and air-conditioning installations and refrigeration applications, which are electrically, electronically, or pneumatically actuated, and which measure and control variables such as temperature and humidity; also included are automatic regulators used as components of household appliances. Automatic controls for regulating residential and commercial environments include heating, ventilating, air-conditioning (HVAC) unit controls and building monitoring controls for temperature and humidity modulation. Automatic controls for appliances include oven temperature controls, dryness controls for clothes dryers, controls for gas burners, and refrigeration thermostats and pressure controls. Establishments primarily engaged in manufacturing industrial process controls are classified in SIC 3823: Industrial Instruments for Measurement, Display, and Control of Process Variables; and Related Products; those manufacturing motor control switches are classified in SIC 3625: Relays and Industrial Controls; those manufacturing switches for household appliances are classified in SIC 3643: Current-Carrying Wiring Devices; and those manufacturing appliance timers are classified in SIC 3873: Watches, Clocks, Clockwork Operated Devices, and Parts.

Automatic Environmental Control Manufacturing for Regulating Residential, Commercial, and Appliance Use
Customers for these products primarily are equipment and appliance manufacturers, electrical contractors, and large industrial users. The market for environmental controls is principally affected by activity in residential and commercial construction. In 2003 the total value of shipments in this industry was $2.25 billion, down from $3.26 billion in 2000. However, the heating, ventilating, and air conditioning (HVAC) segment experienced increased sales in 2004 as residential housing starts remained strong and commercial building began to increase slowly, which boded well for the automatic controls sector.
This industry is composed of two groups: manufacturers of automatic controls used in residential and commercial HVAC units and manufacturers of automatic controls used in household appliances and industrial equipment. Manufacturers of automatic controls for HVAC units primarily distribute their products to suppliers for building construction and contracting firms. For industrial upgrades of HVAC systems, the controls also are sold directly to end users. Manufacturers of automatic controls for household appliances and industrial equipment typically are subsidiaries or divisions of large establishments, where other subsidiaries or divisions of the same establishment use the controls to assemble appliances and equipment.
HVAC unit controls are the industry's major product. These controls are produced for residential and commercial buildings and come in a variety of styles to meet industrial needs. Factories using temperature and humidity-sensitive chemicals and materials require highly sophisticated environmental controlling systems. Computerized HVAC monitoring and controlling have made some printing plants more efficient; such systems provide information for facility operators to electrically monitor HVAC operations from a central location and independently provide cooling and heating of water pumps in ways that save energy.
