It has come to our attention that the majority of furnace manufacturers who previously banned the use of furnaces for the heating of homes under construction in Canada have now reconsidered their position.
Furnace manufacturers will each be issuing notices which outline the specific requirements that must be followed in order to use their products for construction heat applications, which include requirements such as a four-inch thick MERV 11 filter, verification of furnace operating parameters and furnace cleaning following construction heat usage. As an example, I have attached the instructions provided by Goodman, but other manufacturers may have slightly varying requirements.
Please speak to your HVAC contractor and/or furnace manufacturer representative before proceeding with construction heat. In light of this sudden change, there may be some challenges in the field with the gas utilities and/or regulator as construction heat practices are re-introduced, so please ensure compliance with the specific manufacturer’s requirements.
Should you have any questions, please do not hesitate to contact me.
