C & K Air and Heating Inc. was established in 1974 at a kitchen table in Memphis Tennessee by two men, Don Caskey and Sam Kirk. They serviced mostly apartment complexes until one year later when Don Caskey decided to get out of the business and Sam Kirk bought him out. Sam decided to concentrate on taking care of single family dwellings and took a great deal of pride in offering quality service with an unparalleled commitment to the customer. He built his business based on word of mouth and hired others who shared his philosophy on customer service.

In the 90's, Sam acquired the company that gave him his first job in the HVAC field, Controlled Air Inc. In 1998 his son, Chris Kirk, came to work for him where for the next 10 years Sam taught him the business from top to bottom, but most importantly taught him the value of customer service and his commitment to honesty and professionalism. In 2009, at the age of 72, Sam handed the business to his son Chris with the quote, "take care of my customers, because they have taken such good care of me." That commitment to customer service remains today and will continue through the many Kirk generations that will carry on Sam's good name.
