Our Team

John Breese
I grew up on our family farm near Fredonia and graduated from Lakeview High School. When my wife and I married in 1980, we moved to Mercer. I started in the HVAC field in 1981 as a sheet metal fabricator. In 1991, I started Breese Heating and Cooling, initially working out of our home. We moved to our present location in 2006. We have 5 children and 5 grandchildren and can often be found traveling to visit them.
Kathryn Breese
I have always lived in Mercer County. I grew up in Stoneboro and graduated from Lakeview High School. John and I were married in 1980 and moved to Mercer. Breese Heating and Cooling was a dream of John’s that was launched out of our home in 1991. I spent most of the early years raising our children. As they have left home, more of my time has been spent in the business. We have five children and five grandchildren which we enjoy spending time with as much as possible. I also enjoy swimming and spending time near the water, walking, reading and cooking.
Ron Knapp
I am the first employee that John hired in 1991. My hobbies are guitar playing, singing, canoeing, driving antique cars, raising butterflies and collecting Allis Chalmers tractors.

David Rice

David Rice hails from Northern Vermont.  He often hears "where are you from?" due to his strong New England twang. In 2014, David moved to Pennsylvania to be closer to his wife's family, who reside in Mercer. He has been a senior service technician at Breese since August, 2014.  David began his career in the HVACR field when he joined the army in 1982.  His initial training and certification was a four-year program in HVACR, followed by 30 years of continuing education and field experience.  He worked for the same commercial heating and cooling company in Vermont for 30 years, first as a technician, then service manager, operations manager, and finally, vice president.  He specializes in design/build, retrofits and new installations. David and his wife Julia both enjoy hunting, boating and fishing on Lake Erie and other lakes in the area.
