Heating, Ventilation and Air Conditioning (HVAC) systems have seen major improvements in efficiency and functionality thanks to advancements in sensor technology. Combined with Smart Control Systems that connect lighting, fire and security, and HVAC devices, these enhancements have improved user functionality while helping to reduce energy consumption and operational costs.
Solutions for healthy HVAC systems
Switches and sensors have always played a crucial role in the operation of HVAC equipment, from limit switches used in fans and heaters to regulate temperature, to flow switches in chiller systems, or magnetic proximity switches to detect the position of mechanical parts in dampers or valves – the range of applications is vast. While connector technology has also become integral to allow communication across Smart Control Systems. Our products for HVAC applications are built to last, using high-quality materials that help improve efficiency, extend system lifespan, reducing downtime and the need for costly repairs.
Browse our range of standard products or contact us to talk through the specific needs of your application. More often than not, products we sell into the HVAC market are modified or entirely custom.
mid-1800s
Centralised Heating
Buildings began to be heated by radiators using steam or hot water that would go on to replace open fires and stoves, providing more consistent heat.
early 1900s
Air conditioning
The first modern air conditioning system was invented in 1902, with adoption in public buildings in the 1920s, followed by residential in the 1950s.
1970s – 1980s
Programmable thermostats
Heating and cooling became cheaper and more efficient as systems could be programmed to only run when needed, a huge technological step.
1990s – Present
HVAC gets smart
After 20 years of development, the rise of IoT in the 2010s saw smart home HVAC systems take off and develop into the household standard they are today.

Powering efficient HVAC systems in commercial buildings
The evolution of HVAC systems in commercial buildings has been critical in delivering energy efficiency, occupant comfort, and environmental control through smarter infrastructure.
Switches are used to activate and regulate fan units, thermostats, system zones, and pump operation. In control panels and local interfaces, they provide essential manual inputs for system management and maintenance.
Sensors play a key role in monitoring air temperature, humidity, CO₂ levels, differential pressure, and flow rate. In pump systems, they track fluid temperature, pressure, and operational status, enabling real-time control and predictive maintenance to avoid downtime.
Connectors form vital links across HVAC components, including air handlers, chillers, pumps, and building management systems. RJ45, M12, Ethernet and circular types ensure secure and reliable connections in demanding environments like plant rooms and mechanical spaces.
These components help deliver optimised climate control, lower energy costs, and improved system longevity — making them essential to any modern commercial building infrastructure.
