We were tagged by a service technician who conveniently had a salesperson with him. Concerned, we contacted Ken for a second opinion. He was quick to respond, professional and thoughtful in his advice. We ended buying a furnace from him. He didn't try to sell us more than what we needed and was open to any and all inquiries. The furnace was quickly replaced and all outstanding issues quickly addressed. It was a pleasure to work with Ken and we would highly recommend Ken and his company.
