Leo did a fantastic job on our inspection. He was very thorough and informative about educating us on our options. We appreciate that he didn’t try to upsell us. He was very personable and we hope to have him as a technician in the future.

Knowledgeable technicians that produce good customer service.

Desert Diamond Air and Plumbing completed my A/C summer inspection. Timothy did a thorough review and did not pressure me to get the recommended service items. Good company to work with.

Tim explained everything in language I could understand. Did very thorough inspection, installed furnace filters and recommendations for future needs. I couldn’t be happier!

This company has been great from start to finish. I’ve been using them for a year and I couldn’t be happier with the support I get from them. My system is old and the technician Leo was more than upfront and honest with everything that was wrong and made me feel comfortable with fixing what needed to be fixed. I am so glad that I found these guys because I will be using them as long as I live here!

Arturo was awesome. Kind and courteous! I appreciate his patience in answering my questions!

Good customer service

Exceptional Service from Ian S. and Desert Diamond!I have been using Desert Diamond for years (they even installed my new air conditioner a couple years ago) and they have earned my HVAC and Plumbing business forever. Their latest service only solidified why I will never go anywhere else.Ian S. came out to install a water softener system, Reverse Osmosis system, a pressure regulator and some plumbing rework throughout the laundry room for us, and his work was absolutely impeccable. From start to finish, his customer service far exceeded my expectations. He was extremely friendly, personable and so good with my annoying dogs too!!What I appreciated most was his incredible attention to detail. Ian took his time to make sure every single aspect of the installation was perfect, and he left the workspace absolutely spotless. He also took the time to explain everything thoroughly, ensuring we knew exactly how the new systems worked before he left.If you want honest, meticulous, and top-tier service, ask for Ian at Desert Diamond. They truly are the best in the business! And worth every $!

Phillip L is the man. Great service and demeanor. Very professional and not pushy salesmen. We will be servicing with you every year.

I called Desert Diamond after a home inspection showed heating unit not working correctly. They got someone out the same day. Phillip was very responsive and professional. He let me know when he arrived since the home was empty, and promptly notified me with his findings. Thank goodness the issue was minor incorrect thermostat wiring, but he explained and fixed the issue quickly. Next time I need a thermostat replaced, I will call Desert Diamond and not use a handyman.

Excellent work! They came out the same day, diagnosed, and fixed the problem in under an hour. Sam was awesome!

YOU ARRIVED ON TIME AS YOU PROMISED. YOUR SERVICE PERSON WAS VERY PROFESSIONAL AND EXPLAINED EXACTLY WHAT HE WAS GOING TO DO TO REPAIR THE PROBLEM. HIGHLY RECOMMEND DESERT DIAMOND FOR ANY REPAIR WORK THIS NEEDS TO BE DONE.

My other service company didn’t meet my expectations, so I called Desert Diamond. Desert Diamond came out and service my A/C unit… Hayden and Desert Diamond exceed my exceptions… Hayden, the service technician was very informative and descriptive about the issues and fixed them… I will be using Desert Diamond in the future for all my heating and cooling needs!!!

They were asked several times to remove me from their telemarketing list and were only rude and arrogant.

They were asked several times to remove me from their telemarketing list and were only rude and arrogant.

Checkup completed and provided details on status of our system. Answered all my questions and got answers to questions the tech couldn't answer.

N/A

Great service, very efficient, and was fast. We got my HVAC running Again quickly. Thank you to Leo and The desert diamond team.

Great service! Refrigerate coolant leakage noted and fixed. New caps and recharge of refrigerant. Numbers back to reflecting in a positive range. Thank you Nixa, Great Job done!

Great quality, professional, organized, clean. I doubt they are the cheapest in town, but they the highest quality I would bet. I wouldn’t choose anyone else.

Ismael did a great job. He took photos and explained everything in a way that made sense. However I was quoted $445 for a replacement capacitor. Its a $30 part takes at most 30 minutes of labor. Im not sure that price makes sense.However, just for the tuneup it was a reasonable price and I got a lot of good information out of it. Just wish their reports were a little more detailed and came with photos. I can definitely recommend them for a tuneup

Autora was Amazing!! He answered all my questions and was very honest and made me feel better. I definetly will call him again.Nancy

Daniel was excellent! Will recommend to others!

Very professional!

Tyler is a great guy. I highly recommend him to anyone. He truly understands a customers needs.

My technician Sam was very knowledgeable, thorough and professional. My whole experience with Desert Diamond has been exceptional.

Very concerned about good communication. Spent quality time checking the entire system.

As always, excellent, professional, and friendly service.They have great service plans!

Daniel C. came to our home for a tune up. He was so kind and went above and beyond helping us with not only with the tune up but with resetting our thermostat. He was good to explain things in terms I could understand and talked slowly. I hope everyone has the opportunity to have Daniel be their serviceman.

Does his job thoroughly. A very good worker.

I like this company. I like the staff that booked my call. I like their Tech (Mason) who worked on my unit. I trust this company.

Great job getting our 2 units totally up to spec

Desert Diamond is great. They always arrive when they indicate they will, the technicians are professional, and as a customer I always feel like they have my best interest in mind.

Cameron is very helpful and has a pleasant attitude.

Very friendly professional and knowledgeable. Explained everything and answered all my questions. Same-day service was not expected but very much appreciated!

What a polite, articulate young man! And he also did a bang up job, going the extra mile. Our A/C runs like a dream. I can't imagine using another company after this. They have our visit.

Excellent Service

Fabulous company!!! Excellent techs….excellent service

My AC stopped working,called Desert Diamond,fixed it right away,Cody is very knowledgeable,and professional,I would recommend them for all your AC repairs!

they had been called to inspect the work of our current co, Bob Brown because it had been called to our attention this co had a reputation for scamming people. they discovered several things we had been told were needed, were not. Thank you. Your tech was great. Send her any time!

Samuel did a great job - very professional

Tristan was very professional, thorough, and courteous. He took the time to explain everything in a very helpful manner. On a scale of 1-10 I would give him an 11.

This is the experience that convinced me to stay away from these bigger companies.Had them come out for routine maintenance and all they did was recommend multiple $400+ replacement parts for my units (capacitors and contactors). Showing me pictures of readings on them and saying those readings indicate the parts are on their way out. Trying to drive urgency by telling me I don’t want them going out in the summer so I should replace them now.A capacitor is a $20 part and is an easy replacement taking 15-30 mins. Hardest part is taking the proper safety precautions because you’re dealing with electricity. Do the math on that, they’re essentially charging $800 an hour for labor/overhead.Worse, I changed the capacitor myself 1 year later when my AC breaker was having issues at the electrical box, thinking it could be the capacitor. The old capacitor ended up being in perfect condition with readings perfectly in spec. Meaning, either their tech didn’t know how to take readings properly…or he purposely showed me bad readings to convince me to pay for a new one.Which makes me wonder how many people they’ve tricked who don’t take the time to challenge what they’re explaining to you.To top it off I had an independent guy out a year later for maintenance and he noticed numerous little things desert diamond either missed or ignored that he took care of under the basic maintenance visit. He also told me the contactors are in great condition and didn’t understand why they were being recommended for replacement.Could go on and highlight things like them not putting things back together properly after a duct cleaning which required them to come back out to get my AC working again. But hopefully you get the point.

We had our AC tuned up. Friendly and professional service.

INSTALLATION: 4-22-2026: Shawn and Alex did a great job installing my new DAIKIN AC unit They were professional, patient, respectful of my property and knowledgeable about the unit. They explained how the thermostat works, answered my questions, and made sure the install was perfect before leaving.I do wish they'd worn shoe covers as the estimate guy Craig did. Also, the crane (3rd party vendor) was almost FIVE hours late - not their fault, but this did slow the project's progress. Alex and Shawn, made the most of their time, did all the pre-installation / setup work on my roof while waiting for the crane to arrive.The DAIKIN unit is running quietly & smoothly. Next week another employee will inspect the installation to ensure all was done correctly and the unit is running per spec. NO AC company has ever done that, and I'm most grateful. Five stars all the way!----------------------------PROPOSAL & ESTIMATE 4-14-2026: Craig O. came to my house to estimate the costs of a new A/C unit. He patiently, knowledgeably answered all my questions, explained my options carefully & wore shoe covers to keep my carpet clean. Craig's expertise in this field was obvious, he's a wonderful ambassador for his employer, too. I can't recall when I enjoyed an A/C installation estimate visit more; there was no pressure, no stress for me. I HIGHLY recommend Craig, he knows all aspects of A/C - heat pump units.

Desert Diamond Mechanical is outstanding, they are honest quick to respond and prices are very reasonable. Their technician are very professional, thorough and very responsible. They are the only company that I will allow to touch my Beazer home.

Tyler came and gave me a quote for new Hvac system& was very knowledgeable &efficient with excellent communication skills.Very courteous&made me happy I'm having Desert Diamond do an outstanding job again for my home.

I don't know what happened to the text in my review.Johaan was excellent, very courteous and knowledgeable. Explained his actions during his tune up and findings. I couldn't be more pleased, have been using Desert Diamond since they installed our new unit 5 years ago.

The technician sent to my home, Antonio, was phenomenal. He diagnosed my AC problem and solved it quickly. Very professional and answered all of my questions. Very glad I use Desert Diamond.

Damian was great!

This was a semi annual inspection of my HVAC system. Desert Diamond does a great job and very professional

Timothy is very efficient and knowledgeable about our HVAC system

When I first dealt with desert diamond ac I worked with Steve. I enjoyed and felt comfortable with him. He was very knowledgeable and easy to get along with. I bought “top of the line” Trane system because of how long it was supposed to last. It has been relatively problem free. Now at the end of warranty major problems. New salesman NOT HELPFUL. He said So sorry I bought a top dollar system that did not last though warranty, just bad luck. It is “fixable” , but would be better ( assuming for him) if I bought a new system. When I asked for quote to fix this unit he wanted to charge me $89 for a quote. That is TOTALLY unacceptable! I don’t know who’s policy this is but I can get lots of quotes for free when they have to come look at the unit. Desert diamond should have been able to give me a repair or replace quote ON THE SPOT, not charge for repairs quote. I feel I was getting railroaded into buying a new system. Horrible customer service!

Thomas, the tech that checked out my system was wonderful to work with. Very informative, concise and easy to understand. Great Job.

Wonderful customer service, excellent diagnostics and communication! I have worked with many companies over the years, Desert Diamond blew me away with their exceptional service. Ismael is a must request!

Tim was great! He came did his job and was professional, even with my dogs running around bothering him. He let me know about the additional needs and that they were not pressing, but will need to get it done. Which o appreciated.

Received the call to let me know he was 30 minutes away, then he went about his service check in a very assuring manner. He was thorough and professional and answered all my questions.

Great communication, prompt and thorough service, and fair pricing. Would highly recommend.

david was prompt and professional - tests completed and recommended services were explained well

Great experience and super Technician, Ishmeal. Thank you!

Great service from Daniel today!

My tech Johaan was here early, fixed the issue with my ac not blowing cold air quick, super friendly and respectful. I couldn't ask for better service!

Craig was amazing to work with! When I found out that the coils were rusted out and leaking freon in my old Amana AC unit, I made many calls to many AC companies to get quotes on repairing versus replacing the unit. Craig was one of the only people to call and provide a quote for a new AC unit over the phone. When I called him to come out to finalize the quote, it was spot on from the original quote he provided over the phone. He took the time to ask me my concerns on my current AC set up and provided solutions to those concerns. He thoroughly explained everything they were going to do. He gave me the choice of a 10% discount off the AC unit or a 10 year labor warranty. He was also able to get me 0% interest for 3 years. He was able to get me the best price for a higher model Trane than any other company I called. He was even able to accommodate a last minute schedule change for when the weather was cooler.

Timothy was very thorough and glad to answer any questions that I had.

Great experience with Tyler from Desert Diamond. We chose to go with Desert Diamond based on their customer service and fair pricing

Very Professional.

The team at Desert diamond Mechanical were amazing courteous, and have saved me a lot of money on electricity after installing the perfect AC unit. Thank you for the savings on the unit and the electric electricity.

The installation of the new mini-split system in my garage was: high quality, clean, professional and very friendly! No unpleasant surprises at all!I highly recommend this company and we will sign up for their incredible Diamond Service Plan!

I wanted a locally owned HVAC company to do AC service ahead of summer. God knows how hot it can be here in summer. I was pleased to experience the honest service offered by Desert Diamond Air. Dominic arrived as scheduled, did the service checks and kept me informed about my 9 year old system performance discussing improvements with pictures before and after. I was impressed by his honesty. After he had installed a part that did not improve function he showed me that it made no difference and then removed it. I opted to sign up for the service plan. I have no hesitation in recommending Desert Diamond to anyone.

Very reasonable service charge. Johann was great.I would highly recommend this company.

Arturo came out within the hour , was able to diagnose the problem very quickly and explained everything thoroughly . He fixes the problem on spot . Didn’t seem like it was overpriced but have nothing to compare it to . Would recommend and use them again ! I liked That they sent a pictures of the tech so you know who to expect at your door and emailed copies and pictures of everything

A very much appreciated review of our AC systems!

Sam came out and was excellent. Very friendly and very thorough. Price was great.

Love these guys! I had two systems installed by Desert Diamond and now have my maintenance done by them at a new property because they have great trustworthy people. Their Techs are the best, so personable, professional and transparent. They have my highest recommendation

Our technician, Timothy did a great job. Thorough and professional. And he was enthusiastic about his job, explaining every step of the process while performing semi-annual tune-up of our HVAC system. Highly recommend.

SERVICE WAS EXCELLENT, THEY WERE ON TIME HELPFUL AND COMPLETED THE JOB IN 5 HOURS. THE PRICE WAS EXTREMELY COMPETITIVE. I RECOMEND THEIR SERVICE TO EVERYONE.

Dominic was great and explained everything that needed to be done. He took plenty of pictures showing where the problems were.

We were extremely pleased With Desert Diamond Air. Ossiel was the technician sent to our home. He was extremely personable,thorough and knowledgeable. He took his time when checking our equipment It never seemed to be in a rush to leave. We were able to get a technician out In a timely manner. 😊

Appreciated the service and approach to maintenance and ensuring that the HVAC was clean and working well

Leo is personable, knowledgeable, and friendly. He took the time to explain everything and was very thorough.

Eric was efficient and diligent in solving our heating issue. We would use this company again.

Experienced and professional workers.

First off they got me in within a day. Then Paul was so great he walked me threw all that he saw and asked questions as well. Im greatfull for him and his company. NOW I know not to go with the other company who tried to scam me basically into buying stuff I did not need. THANK U PAUL! keep up the great work..

Great job by Tim today servicing my two HVAC systems. Very knowledgeable and professional guy.

I appreciate Ismael for coming to see the problem of our A/C. He was patient and cooperative with the other company who he had spoken about the information needed for warranty.0

Everyone at Diamond desert has been great and what more can I say about Arturo, an expert at his trade and walks you through what he’s doing to resolve the issue. A great person that represents the company very well.

Stephen, Philip, jojo (?)Thanks guys, persistent, professional, polite - and they know how to help!Desert diamond has done good work for us over the years!

Desert Diamond Air and the tech Arturo, AMAZING. We had been without air for 5 days and other companies were giving me off the rates. I prayed to God on if I should get another opinion and I'm glad I found this company. Cost was very reasonable and the work was done in less than an hr, the knowledge Arturo had on what was going on was astonishing. I highly recommend this company.

Love this company. They're fast, friendly, and honest. I will use this company for life. Their tech Leo is also fantastic!

Sam did a great job troubleshooting the issue and resolving it.

Great work and friendly service. Thanks Ishmel!

So grateful for the service we received today from Aaron and the honest recommendations he gave us! He truly understood our goals and needs as a young family on a budget.

On time, appointment same day as requested. System is up and running.

Timothy and Aaron were incredible. Will be recommending them to friends and family. Knowledgeable, non predatory, and got my AC running on same day

Our heat pump was putting out lukewarm heat. I called Desert Diamond Air as they were recommended by a friend. We had a technician out the next day...our old unit had a small refrigerant leak. Luis gave us a number of options from fixing it ($2500) with no guarantee that there may be more issues in the near future as it was already 10 years old to a new multi-level output "smart" unit with lots of bells and whistles ($14000+change). We opted for a middle option (new heat pump/compressor) with 10 year warranty with wifi compatible smart thermostat. Orlando did the installation 2 days later. Ossiel and David helped later in the afternoon. All employees were WONDERFUL. The unit is working great, and quickly and quietly adjusts the temperature as programmed and manually if needed.We highly recommend this company.

Tyler Estes is very professional and always available! Excellent customer service!

We are very pleased with Desert Diamond and our favorite technician Phillip Lopez, he is so knowledgeable, expresses the process so thoroughly and is very nice and respectful. We were having major problems with our AC unit and Desert Diamond, Joseph the service manager and Phillip completely fought on our behalf with the manufacturer and got us a whole new unit!!! I honestly don't know of many companies and it's employees that work together so strongly and advocate for their customers like this company, we are costumers for life and are so very very grateful!!! Thank you doesn't cut it but we THANK YOU all so much!!Best to all,Christy T.

I was very pleased with Desert Diamond from the initial contact. Their office person, Kaitlyn, was courteous and efficient and set up a service call for within 2 hours that fit into my schedule. The technician, Daniel Mendoza, contacted me to let me know when he was on his way and when he arrived, he was respectful, knowledgeable and thorough. Daniel used pictures and took the time to explain the details of my system's problem and an estimate to fix it. He did a check for any additional problems and explained all my available options. Keep up the good work, Desert Diamond, providing intelligent, courteous and well-trained technicians. Your customers appreciate it!

The technician was prompt and respected my home. He thoroughly inspected my home to get a clear understanding of my needs. And I like that.

Excellent service, tech was extremely knowledgeable and helpful

We appreciated Sam Sheahan’s professional service yesterday. He has a very positive, understanding attitude, knowledgeable, and clear in his communication with us. Thank you, Sam.

Excellent service documentation with photos. Will use this company again.

Excellent customer service and he explained everything that he was doing. I really appreciate the time he took, didn’t seem to rush. He did a wonderful job job!

Daniel Mendoza is an excellent technician. He is very professional, knowledgeable and detailed oriented . He did an amazing job above & beyond his duty. Kudos and keep up the very good work!

Sam was a pleasure to work with.Showed up on time and has good communication skills. Answered any questions I had and did a thorough job.

ALWAYS QUALITY SERVICE, ALWAYS RELIABLE. A NAME IN SERVICE YOU CAN TRUST.

Steve was professional and did an excellent job in explaining the options for replacing my current HVAC unit.

Tyler gave us a wealth of information about a new HVAC system for our home. He was very thorough in his evaluation of the attic ductwork and changes we will need. He took his time with us and answered many questions!

I was very happy with Desert Diamind Air. Phillip was our tech and several other companies had been out and didn't fix the issue. Phillip spent a lot of time diagnosing and ended up fixing the issue. Phillip was very courteous and knowledgeable and I highly recommend him!

Ossiel came out for heater tuneup and let me know everything was in good shape. Also he explained and provided me with information on duct cleaning and aeroseal services. He was very thorough and patient with all my questions and informative about services for today and possibly duct cleaning work.

We had Tyler come out today to give us a quote for a new update AC unit. He was absolutely amazing. We bought our home i2020 and did not even realize that our house needed additional resturns and duct work due to the previous owners adding on additions. He came in did his inspection he was straight forward with everything that our house needed to help cool it down. He was extremely helpful to my husband and I. Even though I was just on the phone because I was at work. He toom the time to explain everything to me. Thank you Desert Diamond Air and Tyler. We are looking forward to having your company work on our new unit.

I am still waiting on the videos and photos that you said you would send me that service tech did at her house?My mother-in-law had called the company to have her AC serviced. Antonio the tech asked her to borrow a hammer as he went in her attic where he also left the hammer and didn’t return it and then proceeded to tell her she would need to replace her coil for $3500- $4500 because she was losing refrigeration. Her unit is less than six years old. We called on a second opinion the service tech came out and said there was absolutely nothing wrong with her unit. He found the hammer in the attic and returned it to her and charged her nothing. I have since reached out to Dakota from Desert diamond and of course he left me a long of excuses on what the service tech was doing, but they had no quote or information on it from him, why? I take it very personal when I feel like the elderly are and can be taken advantage by companies. I’m not understanding why one company can say she needs replacement of refrigerant and a coil leak when the seal wasn’t even broken? And then another company is saying there’s absolutely nothing wrong and doesn’t charge her anything. Maybe the worker was just trying to make money on the side and the company isn’t aware? I also feel like my mother In Law shouldn’t be charged the service fee Dakota said he wanted to get the information from the other AC company. I feel that’s not fair. I’m not gonna throw another company under the bus.I will be reporting them to the BBB!

Nixa came and did a diagnostic on my A/C while my wife was home. She was very knowledgeable and explained everything in clear understanding, and her professionalism was on point. She didn’t push, she took her time asked and answered all questions and we couldn’t be happier. Nowadays having somebody with professionalism and also someone this knowledgeable is few and far between. Thanks 🙏

Gary worked very hard at our house and I felt very comfortable with him and I would like to have him back

Nixa is by far one of the best AC techs I have had in my home. She is very knowledgeable, and a very pleasant person to deal with. If she tells you something belive her, and she doesn't pressure sale you. She's the only tech I want working on my AC unit. Desert Diamond you have a real gem. Thank You Nixa

Fantastic! Nixa was very professional and thorough. On my list for next year.

Very friendly, knowledgeable!

Great service! Got us in quickly to repair AC unit, very knowledgeable and friendly tech.

Danny was professional and patiently explained the problem. He then quickly fixed and, voila, I have AC. Thank you!

Tyler provided an excellent assessment of what we needed to fix cooling our house. Great service explanation and pricing!

Very courteous and highly professional

Our larger Trane unit started having issues on Thursday, and Nixa was out to investigate for us the next day. Part was ordered, and installed, and we were up and running in a few short days. Nixa was polite, on time, and clearly explained the issue and fix. Will continue to use Desert Diamond!

Outstanding service!

Great job!!! Showed up on time and stuck with it until we were getting ice cold air! Extremely polite too!!!

Friendly, punctual and knowledgeable. The tech was able to quickly diagnose the issue and offered insights other companies may not take the time to share. I had no clue that a single air return could lead to blower motor issues.

Excellent service with professional advice.

Apart from quickly aligning with us and addressing our ACU's most urgent issue, Philip was also very pleasantly generous with his knowledge of cooling systems.

Steve provided all the information that I needed to make our purchase with confidence. I would work with DD again . The installation went like clockwork and the guys went the extra mile.

Gave detailed estimate, answered my questions, thorough

Dakota is knowledgeable, thorough and polite.He did a fantastic job

Daniel was very polite and thorough with this service call, I will request him for future service.

On time and professional. No upsell. Completed scheduled maintenance in a timely manner and explained every step of the process.

Great service and staff!!

Jered was great. He took care of our a/c unit & changed the filter. We signed upfor the Gold Club, after he explained the benefits to us.

Philip was very thorough checking out our system. He also clearly explained everything to us as answered any questions we had.

We’ve been using Desert Diamond Air since we chose them to replace our old system 4 years ago, and we have not regretted that decision at all. The office personnel are always professional and courteous when I call, and the service technicians have all been first rate. Today I had the pleasure to meet Dakota, the service technician sent to service our system. He was awesome - a nice young man who was very thorough doing his job. He communicated everything he found as well as all the adjustments he found necessary to keep the system working at its optimum performance, knowing that the hot weather will be upon us soon. Thanks Dakota! Great job today! 😃

Desert Diamond is fantastic. I've been with them 6+ years. The technicians are professional, knowledgeable, very thorough, show pictures of what's wrong with my unit and what's good and take adequate time to make sure I understand needed repairs.Dakota is very personable, thorough and informative. He's been with the company a couple of years and I pray he stays.

Always professional, on time, and completes the job on time!

Excellent, made sure everything was running good!

Ivan was professional and really wanted to make sure all was running right and problems diagnosed and corrected. I do recommend.

Tyler was very courteous, professional and knowledgeable about the company he represents, and of the product we are looking to purchase.

Same technician as previously. Love that. Great job gave options no pressure. Great attitude and professionalism. Awesome 5 🌟

Ivan has come to our house twice and took great care of us both times- We feel he's very honest and knowledgeable. He gives you all your options and genuinely wants to help. We highly recommend him!

Excellent service. Prompt, great job explaining the issue and solutions. Very through. Will definitely use them again.

Nexa was very courteous, and she explained exactly what she was doing, basically about tune up .and suggestive about the part needed to help the compressor.

Julio made it on short notice for a non functional HVAC unit. The until began working once he showed up (of course) but he was professional and thorough in inspecting the unit. The unit is staying running which is good. I appreciate the timely response to my HVAC needs. Thank you!

Erick our technician was great. Very professional and thorough

Desert Diamond has the best technicians. Always on time and very professional!
