Sundawn serves you with over 60 years of experience in National HVAC Service Solutions. Since the beginning, we have always been fast, flexible, business-oriented and continually aim for the top in HVAC service standards.


Stan Parzygnat, President of Sundawn Integrated Services Inc., founded Stannair Conditioning in 1957. Stan Parzygnat, then a 23-year-old entrepreneur experienced in air conditioning and refrigeration mechanical services from the age of 15, opened his original business in his parents’ garage at 90 Grenadier Road in Toronto, Ontario. Stan built that business into one of Canada’s largest and most successful independently owned heating and air conditioning companies serving retail, commercial, retail, industrial and institutional clients from coast to coast.


The HVAC industry has changed dramatically since that time, but Stan's relentless commitment to service endures through his family, Sundawn's service team and Alliance members. The integrity of work, professionalism and service expertise that Sundawn provides its customers today is a reflection of the man who spent his entire life improving the industry standard for customer service.
