Residential condo towers


It’s no longer a secret: there are a growing number of condominium-type residences in Québec. The best way to stand out in the marketplace is to leverage your competitive advantages. Having good ambiance and comfort are must-have selection criteria.

A centralized HVAC system, which is normally located in your building’s basement and combined with a cooling tower, will ensure that your property is comfortable, while controlling operating costs.

You should also deploy an energy optimization strategy in order to save as much as possible!

Multi-residential buildings


Do you want your tenants to be comfortable and more likely to remain for the long-term? One of the main factors in the success of a multi-residential building is having a reliable, responsible and easy to control air conditioning and heating system.
