I’ve done business with a lot of different companies. But, Diamond State has gone above and beyond to meet my family’s needs. They made sure we were warm when temps were single digits and our furnace went out.

After being left with a non-functioning install by a disreputable HVAC Co., we had no AC in the hottest part of July. We were in a desperate situation. Charlie went above and beyond to make certain we had AC. I cannot thank him enough and it is clear that Diamond State is the one to trust with your HVAC needs.

Diamond State is the best! I replaced two package units and both were installed and running in record time. Charlie follows up and to ensure you're pleased with the service. The best HVAC company I have dealt with in all my years of home ownership!

Charlie is a class act. Not only were their prices competitive, but he provided an excellent product! I had all of my ductwork replaced (job started within 48 hours of my estimate during summer), but he also worked with me to have my warranty company replace my unit. While waiting on my warranty company to send the new unit, he kept my home comfortable with window units. He then double checked the work on the installation by the warranty company. Throughout the process, he has checked in to make sure that I’m comfortable and satisfied. As a young woman, I really appreciated that he was always around when his crew was in the house. He went the extra mile on every end!

Diamond State is SUPERIOR beyond measure. I recently moved into the Sherwood area, in a new home a month ago. I had visitors from out of town for the holidays with no air. One phone call. Instant service. Diamond State Satisfaction!

We had Diamond State out this week for a 2nd opinion, when we were told our entire unit needed replaced. They ended up saving us over $2000 and my house is nice and cool now!!! Thank you, you've earned our business!!!!

Diamond State Heat and Air provides excellent and affordable service! They've always responded quickly to our service calls. I highly recommend them for your hvac needs.

Honest, dependable, and they really do a good job. I recommended them to my sister, and she was very pleased. I would highly recommend this company.

Great guys and they knkw what they are doing. Dont call anybody else if you need heat and ac work. Best in the business.

I have called upon these guys for a couple of major jobs that I have had and I must admit that their prices are cheaper than everyone else that I had contacted prior to working with them. Excellent work every time they are called upon. Professional and speedy services every time.

They were referred to me by a friend. I called them and they helped me in no time! Punctual, polite and did an amazing job!! My house is cool again!! Thank you!
