AC went out at 1030pm, in August in Arizona. Our house was up to 92 degrees!! So we called Desert Diamond Mechanical at 8am. They sent a tech same day - only a $70 charge and part of that is credited if you fix something. Steve S., an amazing tech shows up in full protection. Mask and show covers. He was very professional and found out the issue within 5-10 minutes. We are renters so he called the landlord and explained it all to her. He then talked to her family member who had more questions. He was nice and really cares that people make the right choices. He gave the option to fix and was realistic of what the could mean or the options for replacement AC. We chose to fix the problem. He said it would be a few hours, but he was done quickly and the air clicked on. Oh what an amazing sound!! Within 10 minutes you could feel that it was on, still hot but improving. One invoice was paid we got a immediate receipt with pictures of the problems, this is part of their inspection. Its been 3 hours -- house is cooling amazingly. I could not say enough good things about Steve S. and Desert Diamond Mechanical!! We will call them for all needs that they service! read more

Desert Diamond Air - The new unit flying into position! - Heating & Air Conditioning/HVAC Near Me - Phoenix, Arizona

Desert Diamond is the BEST! They just completed installing our new heating and air conditioning system along with adding more insulation into the attic. What a Great experience! Very professional and on time. J.C. and Riley did a quick job removing our very old unit and installed our Brand New Trane. This is probably the quietest heating and air conditioning system we've ever had with the many homes we've owned over the years. The insulation team also did an amazing job filling those areas that needed more blown in insulation that the original builder failed to add. All together this was Terrific. Call Desert Diamond. read more

Desert Diamond Air - Heating & Air Conditioning/HVAC Near Me - Phoenix, Arizona

We had a problem with our furnace not heating. Julio came out and did investigative actions and then some research to determine the motherboard had gone bad. He then had to do more research to find a part as our furnace is eight years old. Fortunately, one was still available with a shipping time of a week. We were contacted when the part arrived and the visit was scheduled within two days. Julio came back out and took great care to ensure the part functioned as intended doing multiple checks. He was courteous and thorough. read more

My technician was Julio. He walked me through everything he was going to do and then took time to educate me on what he found. He used pictures, data, and technical specs to give me exact information. He then provided very clear options and was upfront about pricing and timing. The initial experience with Desert Diamond was very impressive.. read more

Living in AZ you'll have your fair share of needing help with your air conditioning unit. This is the second time I've used Desert Diamond, and have been beyond impressed. I used their after hour services. Nixa was so friendly, polite, and informative - even at 1am! Nothing but the best. I signed up for their maintenance plan because I don't plan on using any other company after my last two experiences with them. read more

Timothy did an excellent job with the regular maintenance of our HVAC system. He was punctual, friendly, knowledgeable, and thorough. Highly recommend Desert Diamond and Timothy. Happy Campers here. read more

Integrity is everything for my family. Desert Diamond has earned my families trust today. So in Oct 2019 we had a company out because we our unit wasn't cooling. I'm not gonna go into the details for time sake. The company quoted us a replacement part and said they did a temporary work around to last us till the repair. Well we put in on hold since it was October and planned to do it in the Spring. Spring came around and COVID hit, which occupied our minds. We forgot to follow up. Well fast forward to this week. Of course a few of our neighbors are having HVAC issues. And I saw this man from Desert Diamond on my neighbors roof working on the unit and it was well after 6pm on a Saturday. I walked the dog out normal route and on my way back saw the man getting his stuff in his truck. So I decided on a whim to ask him a for his card. I said "hey I know it's late and I'm sure you want to get home with how hot it is but I live over there and we had a problem with our A/C a while ago, can I have your card" " he's like oh it's no problem It's no bother at all I'm gonna be workin a little while on this" and then he brought me his card. His demeanor and response gave me those good "gut" feelings. So I called yesterday/Tuesday to be proactive for a 2nd opinion. They were able to schedule me the next day!! Yes!! NEXT DAY, in THIS season! I was shocked. So he came today. I showed him the quote from 2019. Gave him some back story and the problem we had and what we were told. He then went on the roof. Came back down. And he gave us great news!!!! He said "looking at it I don't see anything and I would feel uncomfortable telling you to replace it because it's working fine" which took my by surprise. It was honest the honesty and integrity for me. He was very personable. He was doggie friendly and super knowledgeable. And I grew up with a HVAC/mechanic/military/ jack of all trades for a dad. We talked for a little while. And we decided to go with their 2 year maintenance package!!! Home ownership is all fun and games until you live in AZ and your air goes out in the summer. And now I feel safe and comfortable we won't ever run into that situation because Ryan took care of us. I'm here tooting their horn. I don't often do these reviews but I know that their industry is riddled with a bad wrap, everyone is looking for a trusted advice from and expert, so a lot of us just accept our date and go with it without doing more research. Then they find out they were bamboozled. So I'm here to tell you if your looking for a great company, with fantastic ownership, honesty, respect, and great service people. THIS IS IT!! Go with DESERT DIAMOND FOR YOUR HVAC NEEDS! P. S. Sorry for grammar and misspelling. It's been a great day!! read more

My HVAC system incurred an indoor coil leak in August and AC ran continuously blowing warm air. My company at the time added refrigerant with a sealant, a temporary fix until I could have a new system installed. I exercised due diligence and contacted other companies for estimates. Desert Diamond representatives are incredibly knowledgeable and explained to me the reason my particular unit should have never had sealant added and had that not been done, I might have been able to exchange the coil at a great savings versus an entire new system. I am very impressed with the service techs, sales reps and office staff. This company does it right! read more

Frisco came on time and was very thorough with the air conditioning and duct work inspection. He walked me through the photos he took in the attic to explain why the air flow isn't properly working. explained why the thermostat continues to read 3 degrees difference. Provided great suggestions for maintaining the AC. He took the time to explain what he was doing and provided the details. Great customer service and positive outlook! read more

Desert Diamond is responsive and friendly, and probably as good or better than most AC repair services. However, I decided to replace the condenser fan motor myself for about $230 instead of going with their quote of over $1000. read more

Desert Diamond provided excellent service, and they were able to come inspect my air conditioning in the same day, as we were not getting any cooling. They were very professional, honest, and friendly. I contacted them as a second opinion, and hired them to do the job! we were very happy with the service and will definitely recommend them to friends and family. read more

Very thorough and fair for the money. Great technicians who are always on time and do what they say they are going to do.

I called Desert Diamond at 6am when my A/C had gone out the night before. They were the first company I was able to get on the phone but also schedule a time with. They gave me a time frame and the Tech Ismael was there within the first hour of the time frame. He was polite and efficient, and most importantly able to solve our problem. The visit plus replacement part felt fairly priced! I will definitely be making a follow up appointment for a tune up! read more

Had two new Trane A/C systems installed in 2020. One of the best overall installations I've ever seen - MUCH better than what the original builder had done. Desert Diamond also offered two free system evaluations in their price. Their overall support has been great throughout the buying process and and the initial two years of operation read more

Carlo, in your response to my review you wrote: "I will be more than happy to refund the tune-ups as I truly believe that you should pay for accurate information and if any mistakes are made, you should not have to pay. I have made this offer to you..." I don't think you've made such offer to me before, but it seems you're making it now. Thank you. I accept and look forward to getting $159 back. Have a nice day. read more

If I can give them ten stars I will! We invited several companies to assess a 2-room mini-split system and Tyler at Desert Diamond gave us the most genuine and transparent estimate. He first asked us if anything had been done to our current almost new central air and we told them what had been done. He gave us estimates on different models and what would be the best option for us. We actually went with the cheapest amongst the various proposals (none of them is cheap in general) and he said that it's the best value given the sizes of our two rooms. The whole process is both online and phone call follow ups, they are extremely responsive, super helpful and friendly. I get that it's because it's a sale but, this is why I'm writing a great review for them. They came to install the system and preliminary test seemed fine, not knowing that it's wired incorrectly. These guys spent a lot of time outside in 107F and they were professional and cleaned up very well afterwards. However, I noticed the rooms not getting cooled down at all. I called back and they right away sent a guy (Stephen) over and told us that the wiring was incorrect and it short-circuited the compressor. They right away scheduled the next day appointment and came with a newer unit and reinstalled everything for us in a short time! Luis (hope I got his name right) even double checked after we turned the 2 units on to make sure nothing leaked and all worked as wired. I'm very grateful for all those guys who came in 105F weather in AZ and worked hard to make things right. All the people at Desert Diamond are just amazing people who take their customers seriously. We will continue to hire them for our air conditioning maintenance. I can't recommend them enough. For context, we have the AC Pro 2.5 ton 2 zone mini-split 24K BTU heat pump. We are very happy with this brand so far. read more

Best AC company we ever worked with They answer phones right away and get the job done fast, best prices I will never work with anyone else Thank you Desert Diamond read more

Hayden was prompt, courteous, knowledgeable and professional. Appreciate his service and his company.

Excellent service. Our A/C unit was not cooling. Called earlier today and Dakota was at our house within a couple of hours. Very responsive and thorough. Unit is cooling once again. I would highly recommend Desert Diamond. read more

We have used this company for the last few years and they always do such a good job. They recently installed a new AC unit which has been running very well, but we ran into a small issue a few months later. I called and told them what was going on and explained that it is not an emergency, so no need to rush. They still were able to get me an appointment very quickly - JD showed up on time, did some fast problem solving and communicated the issue very well. It's so nice to know we have a reliable team, especially during the summer months. read more

Back in March 2020, we decided to have our old AC serviced (it was installed in 2008). The tech advised that he could service it, it would probably last another year or two, but it was on its last legs. We kinda knew it was time, so we went ahead and got a full replacement, brand new Trane system. The price was reasonable, and our AC has worked great. We signed up for the maintenance program, which has been very helpful in maintaining our system. Even with all that, yesterday afternoon we blew one of the fuses on our AC, probably because if the heat wave. They put us on the list, this is their busy season after all. After a few hours, the tech called and said since it was a simple fix and he was close he would come take care of it. He came at 11pm, and got it done very quickly and was on to his next job. Every person I have dealt with has been professional and courteous. They even let my kid who is obsessed with all things technical watch from a distance when they come service the system. read more

Awesome experience! Communication was fantastic. Tech called about 90 minutes before "our window" to give his ETA. Was very professional and communicated our issue very clearly to us. It is hard to find solid and fair AC professionals, but out tech and this Company has earned my future business. read more

My AC was slow due to the high temps. I didn't think I'd get a company out any time soon but Desert Diamond allowed me to schedule an appointment in a few days (online). They called that day and confirmed I still wanted the appt and a time. The tech messaged 30 minutes before he arrived. The tech (Ivan) was awesome. He explained everything in great detail and told me all the options and what he recommended. He charged my AC unit and it was working better immediately. He was in and out in 45 minutes. I will definitely only call them again when I do annual maintenance and need any AC service - very thankful to Ivan and Desert Diamond for helping me out. I recommend 100%. read more

This is our first year without our home warranty, and we were a bit nervous about choosing a new company to help us out. So glad we chose desert diamond; Nixa was on time, took care of our needs, took pictures to show us exactly what was going on and what needed to be fixed. We look forward to working with them for years to come and hope Nixa will be our tech for the next visits as well. read more

Exceeded my expectations. Great Customer Service. Thank You.

I would like to take this opportunity to say how pleased I am with Desert Diamond Mechanical. They replaced my stand alone furnace and rooftop unit for a package unit. It took one crane, several technicians and one whole day to get my home up to date with the latest and greatest for my budget. They were pleasant, hardworking and polite. All in all, I'm gaining two closets and hopefully some cash in my wallet come summer! Thanks again! read more

One of our air conditioners quit on us. Desert Diamond was the second company I had called for an estimate. -Very friendly office and they send you both email and text reminders for the appointment. -Cody came out on a Friday within 2 hours of my initial call! He was extremely knowledgeable and was patient explaining things to me - I received the emailed estimate before he even pulled away. The estimate was $3000 less than the previous estimate I had received. - Cody came back out on Monday to take measurements and scheduled my install for Tuesday morning - The installation team was super friendly, arrived on time and did a great job. They were thorough and I was very pleased with their work Everything about working with this company was easy and I really appreciate their quick and friendly service. read more

Great service. Diagnosed the problem. Ordered the component. Replaced the condensing fan motor. Friendly and very knowledgeable technician. Sandro M. read more

The tech, Joel, was on time. He was professional, meticulous and very thorough. He took his time explaining our unit and what we needed to improve our system. The cost of $99 for our time up was definitely a good price for the work he did. I did not feel pressured to do any extra service like you do with most companies in this business. read more

We have used Desert Diamond for all of our AC needs. We had one of our ACs replaced several years ago and because we received such excellent service, we again went to Desert Diamond last year for replacement of our second unit. Recently had an issue with the unit, called Desert Diamond and they were immediately out to our home to rectify the issue. If you can ask for Ivan. He is fantastic, thorough and utterly professional, and really takes the time to explain things to you. read more

Wow! This company answers their phones after normal business hours, has a professional person who takes all your information and actually helps you with your HVAC issue. I called tonight for an A/C cooling issue and Ivan was my technician. He was prompt, he called and arrived when he said he would and was able to resolve the problem same evening. I couldn't be more pleased with the responsiveness and professionalism. I would highly recommend. read more

Nothing but stellar things to say about this company! Josh and Martin (I believe these were their names - if not I'll correct) were excellent. Our AC broke last week (it was from 1997) and we needed a new one. They were on time, respectful, efficient in their work, and updated me on their progress the entire time. This may not relate to everyone, but in my past, as a woman, I haven't had the best experiences with guys who install/repair appliances for me. That was absolutely not the case with Desert Diamond. I never felt talked-down-to or disrespected in any way. They were phenomenal and I'm so glad we have a new AC in it before summer arrives. Thank you!! read more

The air conditioner that was purchased a couple years ago for $6,500. Went out this summer. The tech says there is no warranty for this poorly made part from China! $1,500 to fix it!! Buyer beware. They lie and inflate prices. Especially when its 113 degrees in AZ they know you will fix it right away so they gouge you. read more

Knowledgable, friendly, responsive, and great customer service! I'd highly recommend giving them a try!

We have been using this company for almost two years now, and every single interaction with them (from the office people, managers, and technicians) has been professional and satisfactory. They have worked with my family and our unique situation, and we been 100% satisfied with them. The only "issue" we have ever had was an appointment/installation/fix taking longer than we were told or expected. However, the techs themselves weren't expecting it to have taken as long and they were very apologetic as well as professional about it. They were working hard the whole time, so it wasn't a matter of them slacking off or being lazy. These things happen sometimes and they are out of the control of us customers and the techs. As with any company, they may not be the right fit for you or they may not be what you want but for us, they have been fantastic. Their service really is great and we will be sticking with Desert Diamond for a long time. read more

I would highly recommend Desert Diamond! This company has competent staff and technicians who know what they are doing. I appreciate how quickly they responded to my inquiry. They get the job done right the first time. Thank you Desert Diamond. read more
