About Diamond Heating & Cooling

Proudly Serving All of the Treasure Valley

When Rick opened the doors to Diamond Heating & Cooling in March 1999, he had no idea the adventure he was about to begin. Focused primarily on new construction at that time, Rick began to earn a reputation of expertise in airflow and was able to solve the common problem of hot bonus rooms. In 2009, Rick’s wife and business partner, Sue Ellen came to work full time in the company. At that time, they transitioned from a new construction focused company into a residential servicing company.

Rick and Sue Ellen both desired to build a residential company whose heart was excellence, integrity and quality. The servicing industry in general has had, at times, a reputation of not taking care of clients, overcharging and being untrustworthy or unprofessional. Rick and Sue Ellen wanted to break that mold and create a company that stood out from all the rest. They wanted their clients to experience excellence and be 100% satisfied with the service they receive. They call it, “Experiencing the Diamond Difference”!

In 2014, Diamond Heating & Cooling was honored with the BBB Integrity Torch Award. This was a huge accomplishment for Rick and Sue Ellen, because it exemplified everything they had worked for years to create. In December of 2019, Diamond Heating and Cooling received the award of Treasure Valley’s Best HVAC Company for 2020 as well as Idaho’s Best HVAC Company for 2020. This was the fulfillment of a dream and is something that has been a goal of the company’s Vision Statement since 2010 – To become the top-trusted heating company in Idaho.

Diamond Heating was honored to win these awards again in 2021.  In 2022 they were awarded not only Treasure Valley and Idaho’s Best HVAC Company, but also Idaho’s Best Contractor. Rick and Sue Ellen were overwhelmed by these and give the credit to God as well as to their entire team, who have done such an amazing job taking exceptional care of the Diamond Heating and Cooling clients.

Diamond Heating's Mission Statement

Boise HVAC Contractors - Who We Are

Since 1999, we have been building a foundation. A foundation that is made of honesty and integrity. So many companies these days throw the words “Honesty & Integrity” around, but these aren’t just words to us. They are a set of beliefs and actions that we as a team walk out daily. When Rick and Sue Ellen started this company, they believed that if they would treat customers the way they would want to be treated, then their company would thrive. And it has.

Diamond Heating & Cooling was built on the following mission statement. When we are in your home, ask us to recite it for you; the entire team has committed it to memory and we recite it daily. Why? Because it is THAT vital to our company!
