So Very Impressed

Diamond Harris was the HVAC Design who came to my house to give me an estimate for a tankless water heater. I was so very impressed. His customer service, extensive knowledge, and professionalism certainly earn the grade of an A+. A true reflection on black hills Inc.’s hiring practice of hiring and retaining only the best employees. My estimate included not only the tankless water heater but the full installation. Diamond Harris is an asset to your company. Black hills inc was referred to me by my parents who had 3 major projects completed by black hills Inc., and loved working with them. With employees like Diamond, I now see why. Such a positive experience. Thank you. Please give my sincere thank-you to Diamond
