Alan Heating Air Conditioning, Inc.

John Alan Macnider founded Alan Heating Air Conditioning, Inc. in Elmhurst in 1948. With ambitions to create a company known for customer satisfaction, he instilled his belief that a customer is not just a "sale" but a lifelong friend. Roger Alan Macnider joined his father in 1949 and has carried the tradition on. His grandson Michael Alan Macnider joined in 1977 and has since kept the same courteous professional service.
