Requirements for the energy efficiency report, as listed in Schedule IV of the Regulations

  • type of product (large air conditioner, heat pump or condensing unit);
  • brand name;
  • model number;
  • manufacturer;
  • name of the organization or province that carried out the air conditioner, heat pump or condensing unit verification and authorized the verification mark that will be affixed to the air conditioner, heat pump or condensing unit;
  • cooling capacity in kW (Btu/h);
  • heating capacity (if a heat pump) in kW (Btu/h);
  • Air-Conditioning and Refrigeration Institute (ARI) classification;
