Meet Our Founder: Ray O. Cook
Ray O. Cook started his business out of his garage in 1947. His goal was to provide services centered on a strong work ethic and integrity. Soon enough, his reputation earned him work throughout the Sacramento community. He and his team worked on major buildings like the Sacramento Convention Center, Mercy General Hospital, and county administration offices. His commitment to his business never wavered, working 12-hour days up until his retirement in 1998.
2026
Today, Ray O. Cook’s business continues to be a reliable source of HVAC services in Roseville, CA, and throughout the Greater Sacramento Area. We offer a wide array of services, including HVAC installations, maintenance, and repairs. Our dedication to a strong work ethic has never wavered, and each of our employees is highly trained and certified in this type of work.
1947
When Mr. Cook began working from his garage, central heating and air conditioning were luxuries most people could not afford. However, as the popularity of central heating grew, so did Mr. Cook’s business. A small operation that began in a garage became a staple in the Sacramento community. Mr. Cook and his team took their place on the cutting edge of AC technology and repair services.

Our technician Jose was on time, super professional, and made everything make sense to us. I signed up for the Cook Club because I feel like this is the kind of company I want to look after our HVAC for as long as we own this house.Posted on Google![]()
