HVAC systems (heating, ventilation, and air conditioning systems) allow you to alter and maintain a comfortable indoor environment, providing a comfortable temperature and an acceptable level of indoor air quality. Cooling systems, on the other hand, are often used to keep a room, environment, or mechanical element cool.

HVAC and Cooling Systems include everything you need to maintain the temperature and air quality of a room, space, or building – think air conditioning and ventilation systems and accessories, boilers, burners, central heating elements, chimneys, fireplaces, heat pumps, natural ventilators, transpired solar collectors, and more.

Using SpecifiedBy, you can search the biggest range of products in the UK, allowing you to source and compare the HVAC and Cooling Systems products for your project, from the industry’s leading suppliers, such as AmbiRad, Baxi Domestic, Colt UK, and Gaia Climate Solutions.

Search and compare boilers, radiators, circulator pumps, fan convectors, air separators, outdoor sensors, firetables, solar panels, and much, much more.
