In the early 1990’s, brothers Pat and John Kelley repaired and installed Heating and Cooling equipment for friends and family members in their free time. Over time, word spread of their amazing service and craftsmanship. When they both retired from the Plymouth-Canton School District they decided to open Kelley Brothers’ doors with long time friend Mus Kay who had just sold his commercial mechanical contracting business, Thermal Engineering.
Due to the great referrals from Pat and John’s friends and family and Mus’s industry contacts, Kelley Brothers quickly became one of Michigan’s premier commercial and residential heating and cooling companies. Looking to diversify, Kelley Brothers added Automatic Standby Generators to their growing list of services. After partnering with DTE Energy, Kelley Brothers became Michigan’s #1 automatic standby generator install, service, and maintenance contractor.
Through The Beginning Years, Kelley Brothers continued to see exponential growth and well on their way to achieving their goal of becoming Michigan’s #1 preferred contractor for Heating, Cooling and Automatic Standby Generators.
