    Matthew Burden was exceptionally knowledgeable, thorough, articulate, professional and personable. He could see what the issues were, explained them to me very clearly and presented solutions Desert Diamond could offer to solve the issues. He was not pushy but just presented it all very clearly and answered my million questions - probably sometimes twice. He contacted others to insure some specific information he was giving was completely accurate which, to me, was a picture of a good team.

    I just had a install of a new system by David and J.C. on Monday, 5/13/19. Everything went great. The team were professional, took care of my property, and cleaned up after themselves. Several times during the install, I was asked if there were any questions. I would recommend them in the future.

    We own a commercial building in Peoria. We contacted 2 other company’s. After talking to dessert diamond, it was a no brainer in or decision to work with such a Fine company. They worked with us, from the extremely competitive price quote, to the large installation of Our equipment. They said what they were going to do, on time and on budget. Melanie in the office, to the owner Carlo, and more importantly David and his great team. We are very happy with there performance. Thank you

    Thanks to both Steve and David for exceptional service and attention to detail. We had some initial glitches, but things were fixed quickly. I have confidence in their ability to keep my HVAC running smoothly.

    This was our first experience with Desert Diamond and we are very happy. Insulation installers Kent and Nathan were on time, very polite, did a great job and cleaned up after themselves. They explained the process and steps they would do and in a short time the job was completed. Materials and labor were very good and the insulation was installed to the proper depth to achieve a R49 value. Also Steve, who quoted and explained our SRP home energy audit to us did an excellent job. Thanks DD.

    Thank you William for an excellent job checking our air conditioner. He was knowledgeable, friendly, professional, and he explained all of the procedures in layman terms for me to understand. I would definitely recommend Desert Diamond Mechanical and William!

    Yesterday was my first appointment with Desert Diamond and I was impressed. A company that is professional. I like to deal with people who are pleasant and honest. The tech, Ryan, represents the company and was most pleasant to work with. He was polite, courteous, took time to explain things, was thorough and I couldn't be more pleased. I am sure all the techs are very good if they are like Ryan, but I will be requesting him for future appointments. Thanks, Ryan, for a job well done.

    My experience with Desert Diamond started last summer when my AC went out. I called them around 7:00 p.m. on a Friday and they arrived at 7:00 a.m. on Saturday the next day. Jeff came out, within 2 hours my AC was fixed and back running. This year we decided to have a new AC and had Desert Diamond quote it. Again Jeff is the one who came and gave us the quote, Jeff I have found to be very honest. We went with Desert Diamond and are very pleased. The installer were great....
