In 1985, Performance Heating & Air Conditioning, Inc. was formed with one thing in mind — a commitment to excellence. It was this conviction, along with an ability to attract talented and loyal employees, that quickly built our reputation for quality workmanship, exemplary customer service, and integrity. Performance Heating & Air Conditioning, Inc. acquired GSC Refrigeration, adding commercial refrigeration to our range of services. In January 2008, the company was renamed Performance Mechanical Group to better reflect the type of services we provide. Today, over 35 years after its inception, Performance Mechanical Group is one of the premier mechanical HVACR contractors in the Puget Sound area. We take extreme pride in the principles upon which this company was founded.
