A Family-Run Business for Over 40 Years
Major Heating and Air Conditioning was founded in 1970 by Jack E. Major Sr. and his son Jack Major Jr. as they initially focused their business model on servicing single pipe steam boilers. As ambitious entrepreneurs, they quickly expanded their services into the broader Denver HVAC market, and set out with a mission to provide genuine care for their customers, quality HVAC service, and most importantly to build lifelong relationships. Need proof, they are still the primary HVAC service provider for one of their first customers, Fairmount Mortuary in Denver, CO!
The Founder’s core values quickly established Major as a business known and respected for having exceptional ethics that mirrored those of its customers. These core values are what led to the development of the Major Service System™; an exclusive 360° degree service model that ensures that our team customizes options that best meet your lifestyle and expectations. Today, Jack Major Jr. still resides as the acting President in partnership with his wife Mariann and two sons Bob and Jack C. Together as a family with their valued team of professionals Major continues to grow its market shares while never sacrificing the principals that got them here!
