The Ontario Building Code mandates a CSA F280 heat loss and heat gain calculation for all new residential construction and major renovations. Without it, your permit application is incomplete — and your HVAC system may be improperly sized, leading to comfort problems and higher energy bills.
A properly sized system based on a certified calculation is the foundation of every efficient, comfortable home.
Based in Meaford, Ontario — we serve residential and commercial projects across Grey and Simcoe counties.
