What Makes Gainey's Heating & Cooling Different?


Our service after the sale sets us apart from others!


We are proud to have provided heating, air conditioning, refrigeration, air quality and service for more than 20 years in the Hartsville / Darlington County Area – the area we also call home.


We are family owned and operated–and are blessed with an amazing team!!



Mike Gainey, owner and operator, began his heating and air conditioning career when he was in high school. He worked his way through the ranks at local heating and air companies – learning both residential and commercial systems. He started his own business a few years later, and incorporated in 1997. Mike is married to Renee Gainey. They have two children: Brittany and Jonathan – who is married to Susan Funderburk Gainey. They have one precious grandson, James Michael.
