How It All Started
Stephen Rathje didn’t plan on starting an HVAC business in 2006. He just wanted a job that paid the bills. But after a few years in the trade, he realized something: he had a real knack for solving problems most people found frustrating. He liked the challenge, and he enjoyed helping people.
In 2019, he launched The Climate Doctor Heating & Cooling. What started with one man and a few tools grew into a team of certified HVAC technicions trusted all across Michigan’s Thumb. Today, we serve homes and small businesses from Pigeon to Bad Axe, and we still treat every job like it’s right next door.
