Retrocommissioning refers to identifying improvements that can increase the energy savings and performance of existing buildings.

Chillers have long been the HVAC systems of choice for large commercial buildings and other facilities, but they are facing fierce competition from new technologies, such as VRF systems, which are frequently considered to be easier to install and maintain.

HVAC systems in commercial buildings consume a lot of energy, which is why many building owners and managers are looking at replacing their older, inefficient equipment with new high-performing systems.

An investment in a new chiller is not one that building owners make lightly. Owners typically need and appreciate the guidance of a knowledgeable HVAC contractor when making this purchase as there are a number of factors that go into the selection process, and not all of them are necessarily related to the actual chiller itself.

Commercial building owners and managers count on HVAC contractors to take care of their buildings in many ways.
