For each tenant, Centropolis has installed on the roof one or more HVAC units calibrated to the specific needs of the business.

Centropolis carries out follow-ups on this maintenance; each tenant is required (as written in the lease) to have a service contract with a specialized company. This contract outlines the frequency of the changing of filters, belts, lubrication and visual inspections. The contractor carries out preventative maintenance during four annual inspections according to a detailed contract that specifies:
All Centropolis air conditioning is provided by roof-mounted units. Centropolis only installs new units, and the oldest ones date from 2000. All of the units use the same type of gas, namely HCFC-22.
