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!

Our clients are our lifeblood: therefore, we are in the business of creating clients for life. Through honesty, integrity and quality, we want to earn their business as we serve their heating and cooling needs with efficiency while creating a trusted professional relationship. It is not about what we can get from our clients, but what we can give to them.
