Therwood Heating & Cooling
Therwood Heating and Cooling was started by its president Chuck Catherwood in 1995, with the purchase of James Lee Burner Service.  Chuck along with his wife Michelle operated the business from their home, offering sales, service  and installation of heating and air conditioning  equipment.  As the business grew Chuck hired his nephew Gerry Catherwood who is still with us today as manager of our service and installation team. We outgrew our home office in 2000 and moved to a 2000 sq ft. shop and office. Therwood prides itself on being a local, family owned business that cares about its customers and community.  We strive to answer every call personally and respond quickly to all inquiries  and requests for service.  We have a full time office staff in place to ensure that we can meet this requirement.
