I am very impressed with Diamond! Aug 22, 2025

I am very impressed with Diamond! I had my furnace, AC, and hot water heater replaced, and the entire process was made seamless and easy by the team. Derik and Steven were my installers, and they were just the best. Steven even helped me out on a quick side project, unrelated to the main job. Derik always had a smile on his face, and it was clear that he took pride in his work. He also took a lot of time explaining the new system to me, and even let me practice removing the filter while he was there so that I would know how to do it later on my own. From the time my furnace broke to when I had my new system, I felt that I was in good hands. Sky, the comfort coordinator, even dropped off a loaner cooler as temps hit 99 that week. This is a great company with a great team!

Professional and Very Precise Crew Aug 20, 2025

The crew was professional and very precise in telling me about the furnace and air conditioner that they were installing. I would recommend Diamond Heating and Air in a heartbeat!

We were very happy with Diamond. Aug 14, 2025

We were very happy with Diamond. We especially appreciate how they stepped up to resolve a Rheem supply issue that would have left us without cooling for an unreasonable amount of time. And their commitment to getting our new heating/cooling system to work optimally in our home. Thank you! Jason was a pleasure to work with and did an excellent job explaining our options. A pre-installation visit from Roland and Ryland was reassuring and helped them come up with the best installation options. Led by Mitch, our installers were Derik, Steven, and Josh. They were a friendly, capable, and professional group. I particularly want to acknowledge Derik for his work in the crawlspace installing a new, hard-to-get-to vent. Plus, his ensuring that some other ducting was attached correctly both in the crawlspace and garage attic.

Derrick was awesome! Jul 1, 2025

Monday 2/3/25 I got a new furnace and AC unit installed by Jonah and Derrick. Jonah was quiet, but got the job done. Derrick was awesome! He worked really hard and still had time to occasionally interact with me, pleasantly and professionally. Derrick has a wonderful sense of humor and a winning personality and, as an apprentice, he showed excellent skill and initiative in explaining things to me and making sure I was satisfied with Diamond's service. He even laughed at my dumb jokes as I named my new AC unit 'Moby' because it's a big gray whale! My only negative was that I had to wait seven days for the install, which meant a week of no heat and living in a 55° house. Diamond did loan me a space heater, but Jason said it was an energy suck so not to use it more than I had to. One idea might be for Diamond to offer a weekend install for an extra fee... That way it's more the customer's choice to wait out the weekend.
