Meet Steve.
The Air Flow Specialist.


All-Phase Heating & Cooling is locally owned and operated by Steve Strange, who got his start in the United States Air Force. He joined the Air Force in 1985 in the heating career field. After 6 weeks of basic training and 13 weeks of technical school as a heating system apprentice, he was sent to Florida. His first assignment was in a deployment squadron and most of the heating work was performed overseas in various locations. After 4 years of working on the heating side of the business, the Air Force decided to combine the heating and air conditioning shop (HVAC Shop). He was sent back to technical school to learn air conditioning and refrigeration.
Over the next 14 years, he honed hs heating, cooling, and refrigeration skills. He worked on everything from tent heaters to 1 million BTU boilers, ice machines, walk-in refrigeration boxes, and 200 ton chillers to 2 ton residential heat pumps. He installed and maintained these systems everywhere rom Florida to Delaware to Kuwait, Bahrain, Saudi Arabia, Jordan, Azores, Guam, and Panama Canal thus working under many different power supplies and weather conditions. All-Phase Heating and Cooling was started in Delaware around 2001.
