Pat Randerson - Owner

Pat started Randerson Heating & Cooling in 2003 out of his garage. His family was a great asset in helping him start his business. His mom was the secretary, his dad helped with ductwork installation, and his brother handled billing & taxes. He is very grateful for his family's love and support. His first group of customers were people he met through past business experiences. His business grew from there by word of mouth. His business mainly served the residential side at first but now has greatly expanded into the commercial side as well. Pat believes in being up front and honest with each customer. His approach with customers has made his business very successful. He was able to expand to a second shop in 2008. Pat has a hard working and dedicated team. Pat thanks his team and customers for their loyalty and dedication for making his business a success.
