System Size Calculator

HVAC design and engineeringDesigning an HVAC system to create a better working environment

Cooling, heating and ventilation are the cornerstones to a productive workplace. Our HVAC design engineers will undertake all aspects of each project, including calculations of cooling and heating loads, production of CAD drawings, full project management and pre-install surveys. They will help ensure that the investment you make is both cost effective and fit for purpose.

System sizing use our cooling and heating calculators

One critical aspect is the sizing of the HVAC system required. Numerous calculations are involved, but a fundamental necessity is that the cooling or heating output of the cooling or heating system is greater than the heat gain or the heat loss of the space that is being served.
