The greatest energy efficiency possible for your house

Accredited by the HRAI (The Heating, Refrigeration and Air Conditionning Institute of Canada), we notably ensure the proper sizing of heating and air conditioning equipment for small residential buildings under 6,000 square feet and up to 3 floors (Article 9 of the Quebec Construction Code) by working with two types of customers:

  • HVAC Contractors: Give your customers a proposal based on a specific load calculation that sets you apart from your competition.
  • Owners of new residential building: Make your contractors of choice bid from the same load calculation so as to better compare the proposals.

The best standard for your comfort

We apply the CSA standard F-280-12 for equipment power calculation in new buildings.

Make sure you have load calculations conform to the CSA standard F-280-12 to be eligible for government subsidies. A precise thermal load calculation constitutes the foundation of an ideal climate comfort and energy savings in new residential construction.

According to the plans and specifications of your new home, we will be happy to submit you a service offer for the thermal load calculation and recommendations for the most efficient heating and cooling solutions in the market including geothermal technology.
