McQuay controls are well known as a manufacturer of components used in heating, ventilation and air conditioning or HVAC systems. Among the products it manufacturers are a complete line of control units used to operate automated HVAC systems for residential, commercial and industrial uses.

The McQuay Microtech product lines are known for ease of operation and installation. The MicroTech II control units are designed to operated HVAC equipment manufactured by McQuay or others. The units can include Internet accessibility allowing control of the heating and cooling system from remote locations. The units also include components that monitor the operation of the system. This information can also be accessed through the Internet allowing for remote troubleshooting.

The MicroTech 2000 series of controllers are configured to control water source heat pump units as part of an HVAC system. Water source heat pumps remove and concentrate warmth from water as a heat source during the winter and dispose of heat in water during the summer. This transfer of thermal energy requires less energy consumption than other heating and cooling systems. The MicroTech 2000 controllers include specialized programming for this type of system as well as control conventional boilers and compressors that often serve as a backup in this type of system.

The McQuay MicroTech III product line brings together controls of most every type of HVAC systems including water-sourced heat pumps, conventional boilers, chillers and roof mounted air conditioning system. This system also integrates through the Internet allowing remote access for control and trouble shooting. This system also offers connectivity to a number of standard Building Automation Systems providing a greater level of control.

The McQuay company is currently a subsidiary of Daikin Industries. The original company traces its roots back to the days shortly after the American Civil War and specialized in the production of steam engines. Over the years it has expanded its scope of business to specialize in heating and cooling systems. Along with HVAC equipment, McQuay offers products related to refrigeration. Its complete line of products offers solutions for almost any stationary indoor climate control need.

The complete McQuay product line includes devices for a wide range of HVAC needs. It is well known for its Maverick line of rooftop air conditioning units. The controller products it offers complete the product lines providing the purchaser with the option of utilizing a single manufacturer's products for the entire HVAC system.
