McMillin Air is a family owned and operated Heating, Cooling and Refrigeration business serving the greater Surprise, Wickenburg and Congress Areas. Jason McMillin currently leads the company which has been passed down through three generations of McMillins.

Albert “Mac” McMillin started out repairing refrigeration systems back in 1948 after he had completed his duty to the US Air Force. Though he started out in Glendale as his home, he soon discovered Congress and moved his family and his new business there.  Over the next 40 years he ensured that the McMillin name would become synonymous with air conditioning and refrigeration.

In 1977 Rick McMillin, Mac’s son, would come on board officially as a technician after he graduated from refrigeration school. He worked side by side with Mac until he retired. Together they continued to build a reputation of providing Honest, Fair and Knowledgeable Service

The 2000’s brought about more changes to the McMillin ownership.  Erin McMillin initially stepped up to run the business. Then her older brother, Jason, who had worked for many years as a technician later took on the day-to-day responsibility of ensuring the McMillin clients received exceptional HVAC services.
