We ended up going with a blown in fiberglass insulation of R 38 and 13 inches. His price was the best by a few bucks, but I particularly liked his practical recommendations, and so ended up using him. He booked me out a week later and showed up exactly on time and had the job done in just a couple hours. He even provided me with before and after pictures that I can use when I submit my taxes for an energy tax credit. Very straightforward and honest service I recommend if you're looking for installation to talk to him at least. As it ended up the insulation did basically nothing to help with the temperature in my garage. If others are looking to do the same thing, I tell you to look at a combination of insulation for your ceiling, walls if needed, and the inside of your garage door these metal garage doors really radiate a lot of heat into the garage.

I received quotes from 5 companies for a new AC unit to replace a 20+ year old one. I ended up going with Desert Diamond Mechanical for several reasons. I felt like several of the companies who came out to give estimates gave me a marketing pitch. They had high-gloss brochures and explained basic installation procedures as if they were some highly technical process that ONLY their company uses. Some made fancy computer models of our home in order to see if the current unit size was sufficient (though all of the companies did this even without a computer model and all had the same conclusions). Many of the costs were somewhat hidden in the estimates in the sense there were many back-end costs in order to keep the warranty valid with those companies. Some required 2 maintenance visits a year while others only one, however the cost of these visits varied greatly. Over all, all 5 of the companies I had come out were reputable and offered a quality unit. Jeff, from DDM, came out to our home to give an estimate for a new unit. He was straight forward and was not a salesman. He seemed to be an experienced installer who knew what he was talking about. No fancy brochures, no Costco cash card gimmicks, just an honest review of what needed to be done and what my options were. The estimate was just as thorough as the companies who had the glossy brochures, and I received an itemized email with everything that would be included- installation methods, parts, supplies, etc. DDM's price was just slightly less than a couple of other companies I was leaning towards. What really sold me was they included a 5 year warranty from the start with this price, when others were only giving a 2 year. It was going to be over $1000 more to get the 5 year warranty with these other companies. In addition, their yearly maintenance costs were less-so that saves $ in the long-run too. Several of the installation costs included with DDM were extra with other companies (for example if you needed a crane, this was included while others charged over $150). DDM offered the best value from all 5 companies I spoke with. Some of the other companies called me and said they would price match DDM. My thoughts on this were, why wouldn't you just give me the best price up front? When you know 4 other companies are competing for the job, it would make sense to give the best price up front instead of having your potential customer have to take the time to call you back and wait to see if you will meet another's price. DDM had great reviews, as did the other companies, but the value they were giving set them apart. I appreciated the honest, straight forward, and practical approach Jeff provided. Our neighbors were also pleased and we both used DDM to install our AC units. Mine was installed within a week of giving them the go-ahead. The installation was quick and everything was exactly as they stated it would be. Every time I had a scheduled appointment or visit with DDM, they were very punctual, polite, and efficient. I am very pleased with this company thus far, and so are our neighbors. My advice to anyone looking to get a new AC unit is obviously to research the companies, make sure the equipment you are getting estimates on are similar or the same (apples to apples), pay close attention to the back-end costs such as warranties and yearly inspection costs, look closely at what is included in the installation and what may be extra, and dont fall for gimmicks such as the 10% cash back offers like they have at Costco (the estimate from that company was over $2k higher!). Like one sales person from another company jokingly said, "if you want a $1000 cash card from Costco, we can charge you an extra $1000 and you can get one from us!" My last piece of advice is to make sure DDM is included in your list of companies to get an estimate from. read more

I knew my old air conditioner was soon to go. I noticed my electric bills from last summer were higher than normal. I called Desert Diamond as I found an ad that offered a reasonable price for a tune up. Cody came out for my tune up and I must say he was very professional, knowledgeable in his job, and honest about what he was telling me. He did not feel threatened by me being his shadow and asking lots of questions about my unit. He explained what parts were and what the readings should be and showed me the results as he checked them. After all was said and done my unit had 2 non working parts and the compressor was ready to go. It would cost me a third of what a new energy efficient unit would cost to repair. Cody did not pressure me into buying anything. He gave me all the scenarios and options and the decision was mine to make. No pressure involved. I asked him about the units they sold and got the information I needed to make my decision. He even called another knowledgeable service man (Steve) from their company to talk on the speaker phone with me and explain the unit I was considering. I got all my questions answered and my mind was made up. They gave me a wonderful price d/t being a first time customer and I received a special deal going on with the Trane company at this time (before the hot summer months). I also purchased their extended service warranty. My new unit was put on 3 days later. Ben and his apprentice (also named Ben) arrived on time. They too were very professional. The Smiley Crane also arrived on time. The work was done beautifully and smoothly. Ben took many pictures of the installation and showed them to me after the job was done. Clean-up was awesome. One would never know they were there. Lots of fine points I appreciated such as protecting my stucco wall from the ladder and using booties to cover their shoes inside my house. They included a programmable thermostat and Ben taught me how to use it. He had no problem answering my many questions. I will be trialing my new unit now and Desert Diamond will return in a week or so (what works with my schedule) to recheck the unit and make sure it is running to specifications. When anyone asks me if I know a reliable ac company I will be referring them to Desert Diamond. read more

This company and its employees were AWESOME from the get-go. Jeff was extremely professional and spent a long time reviewing different options with us. He even put on booties when entering the house. He was clean and dressed with a company shirt. We were shopping for a new a/c, but did not plan on having it installed until cooler weather in the Fall. Jeff recommended minor things that would make our new a/c function to its full capacity. After trying to get 2 other estimates, we realized that Desert Diamond was our choice. One of the others could not fit us into their schedule for an estimate. The other company arrived with the owner and 2 workers. We couldn't get them out of our house fast enough. They were back woods characters, although they had some very positive reviews and wanted to give us an exceptional deal. There were too many negatives and our vibes told us to get rid of them. FOLLOW YOUR VIBES. Well, our a/c died and we were unable to wait until Fall. We called Desert Diamond and they were here installing a new unit the following day AND completed the installation within 8 hours. The 3 installers encouraged our questions and covered everything in the utility room, where they had to access to the attic. They totally cleaned up the yard, garage, and utility room. David, the lead installer, was patient in educating us with the new thermostat and answered all of our questions. After a long tiring very hot day, he was patient and in no hurry get on the road until he was sure that we were content, satisfied, and had all of our questions answered. All 3 of the employees were respectful and hard workers. Ask about AeroSeal. We are so appreciative that this was recommended. They did not give a sales push; they just provided information. No other company would have mentioned this because not many companies offer it. And.....there will be a follow-up visit by Jeff in a couple of weeks to inspect the work and make sure all is well. read more

A copy of our letter to Desert Diamond: Desert Diamond Mechanical, My family & I wanted to take a moment to thank you for your all-around, exceptional customer service when it came to replacing our 30-year-old AC unit. Particularly, we'd like to commend Ernesto, who assisted us from the very beginning to the final inspection. When Ernesto came to our home for the initial consultation, he exhibited the utmost professionalism in evaluating our home comfort needs, and in discussing his suggestions for replacement units. He treated us (and our home) respectfully, and answered all of our questions in a direct, honest manner. When it came time to discuss pricing, Ernesto provided a few quotes for us to consider. At no time did we ever feel like he was putting us through a sales pitch. We never felt one ounce of pressure from Ernesto, and we truly appreciate his way of conducting business. It made all the difference in our decision to go with Desert Diamond. Prior to meeting with Ernesto, we received a quote from another large, heating/cooling company. There was a world of difference in how their sales representative treated us. Unlike Ernesto, their representative put us through a series of obvious sales pitches, meant to pressure us (through guilt) into making a decision at that moment. Ernesto, on the other hand, understood that my wife and I needed time to consider our options, and left our home without ever pressuring us for the sale, or trying to manipulate us through sales techniques. We'd also like to acknowledge the installers, Ben and Eric, who exhibited the same, excellent customer service as Ernesto. They both treated us, and our home, with respect and did a thorough, clean, professional job on the installation. Ben was very affable, and more than willing to answer all the questions a new AC owner would have. Overall, we are very pleased with our experience, and we would highly recommend Desert Diamond to others. Thank you! read more

I had not 1 but 3 companies come out and check out my unit-- all sent my my AHS home warranty place... one even said we cannot replace your unit under warranty unless you take a unit we had left over from another job, all you have to do is pay for the other parts." So as a "Hail Mary". I called the top AC companies on yelp got a few quotes all within the same range (a couple hundred dollars from each other). Now Desert Diamond was the only one that told me, then showed me on their iPad, and SEND me exactly what they will be doing. They included each line item and the parts. They even gave me a website to look up each part. Then they guy (whose name escapes me) plainly said if I was not ready and had to research it he would leave and wait. Yes I know that is a partial sales tactic but it was not high pressure. He was not trying to up sell me or force me to make a decision (albeit he was hoping I would say yes). I was impressed. The install guys were great, did a quick job, left everything clean, I even had a home energy audit by APS and they said the installation (without doing a full system check) seemed to be "very well " done. My only annoyance was the install guys kept forgetting the fully close the garage door so cold air kept getting in. They follow up was great, they sent someone to check out the work. Everyone was polite, professional, and seemed trustworthy. read more

Of course the first 95s of the year and my a/c breaks, after reading some reviews I contacted Desert Diamond. Within a couple of hours Ernesto showed up in my door step, he went straight to work and found out we had bad rusted indoor coils and our system was leaking Freon, he gave me a repair estimate upfront and I was very impressed that he dint go straight into trying to sell me a new unit wich I was afraid of. Our unit was a Old 1992 Trane and after I requested we then compared the cost of replacing versus repairing. I decided not to throw bad money after good money and just replaced the whole unit. He helped me fill out all the financial paperwork right there in his tablet and got me approved in a matter of minutes, after i tough I couldn't be impressed anymore by this great company which I was already grateful to have chosen them. Ernesto then offered to drive back to their office and lend us their portable a/c unit which was great help since the install was scheduled a few days ahead. I'm so impressed with the level of customer service the pride their techs take in this company. I'm am now enjoying cold air in my house with a much quieter and high efficiency system.

I scheduled an appointment with Desert Diamond Air Cooling for a routine long overdue air conditioning check. I picked this company based on their reviews and I was not disappointed. Ismael called within the scheduled time window and sated he would arrive in 30 minutes. He and his coworker arrived on time and were very professional. They had to figure out which air conditioning unit as mine since I live in a condo complex because the original air conditioning company who installed them did not label each unit with our unit numbers on them. Such a small thing that should have been down, but they figured out which one was mine. Ismael was very knowledgable. He conducted his assessment to determine what parts need to be replaced, updated, cleared out or repaired. He took pictures of each item and explained everything In great detail. He provided quotes for each item and explained their service plan option too. I made my decision on what items I would address and they took care of each items that same day. Ismael provided updated pictures of each item they repaired, replaced, etc. I would highly recommend Desert Diamond Air Cooling & Heating for all your needs. read more

I had Kevin, with Desert Diamond, come out for a tune-up of my system today. This was the second time he has been out in a month's time frame. The first time was because I installed a new thermostat myself and found that it was cycling too often. I couldn't figure out why. Keven determined that nothing with the system was wrong and that the giant hole behind the thermostat was causing the problem. He suggested I get the entire system looked at and tuned up at some point in the future. So, I finally got around to having that done and Keven showed up again. He only found a few minor things that I could easily take care of myself. He didn't try and oversell me or convince me to let him do it which I actually really appreciated. Bare in mind my unit is 22 yrs old and while he did mention that fact to me, he didn't try and sell me a knew unit. He just suggested I keep that in mind. Honestly a great experience, on-time, friendly, informative and listened to my findings as well. I would highly recommend these guys. read more

Desert Diamond Mechanical is the best Heating and A/C company I have ever delt with. Calls into the office are always answered right away by a smiling voice and returned calls happen very quickly. I was so impressed with their level of service that I purchased a service contract with them that gives me service with any breakdown within 24hours. This summer my A/C unit went out, and in the past when the OTHER GUYS were telling me that I would have to wait days without A/C for someone to come out to inspect my unit because it was summer and they were busy, Desert Diamond Mechanical was at my home within 2 hours and had my system up and running....they even took care of dealing with the warranty on my A/C unit for me and the repair cost me nothing. I have tried other service companies, but these guys give real meaning to the words SERVICE and CUSTOMER SERVICE. I am a also a Realtor in Phoenix AZ and I this company for my own personal residence as well as refer them to ALL of my Real Estate clients. read more

I recently woke up and my AC had quit during the night. It was already late in the day on a Friday and I began to panic because I had to work and I had dogs! I searched the internet for someone to call. I came across Desert Diamond Mechanical. I could not find a single bad review or negative comment about them and they had an A+ BBB rating. I called from work on Friday and said they could have someone there the next day between 11-2. Their employee Cody called back a little while later and said he could make it out the same night if I wanted. I was at work so I had to wait. The next day he got done early at the job before mine and called saying he could make it to my house even earlier. I was so scared I would have to replace my unit. Cody found the problem rather quickly and it was something minor. He was very professional and down to earth. He recommended a tune up also (which I know it needs) I will definitely be calling to schedule that. THANK YOU!!!! I definitely recommend them. read more

As a long-time customer of another vendor, we could not get through to even leave a message with them when our AC failed on Saturday evening. Tried our old vendor again on Sunday, 7/4, with no luck. Did some quick investigation of other companies and came across Desert Diamond Mechanical and gave them a call. Not only did they pick-up, there was actually someone on the other end to get us on the schedule for later in the day. JD called a few hours later and was on his way. He was polite, very professional, and successfully got us back up and running with minimal fuss. JD also gave us some great advice on how to prevent a recurrence of our issue in the future. When I find a professional I can trust, I am very loyal. I'm now considering switching vendors after such great and TIMELY customer service. I definitely would recommend Desert Diamond Mechanical (and JD) to anyone looking for such service. read more

Cody and Jeff are dynamic! I had Desert Diamond come out to my house to repair some items found on my home inspection ( I purchased a new home). Prior to their arrival, the previous owner had already repaired the outstanding items but failed to inform me. When Cody and Jeff arrived to do the work they informed me that it appears the work had already been completed. We looked at the home inspection pictures against the pictures he took and what do ya know....the previous owner did repair it prior to our move in. Cody and Jeff could have very well said that they completed the work and charge me for repairs, but they were completely honest and showed me that the work had already been done and didn't charge me. Now that's customer service and integrity. I will definitely use them again and refer them to everyone I know. Thanks Cody and Jeff you guys are the best! read more

It began in January 2018. I got a crazy idea to move our kitchen to give us an open floor plan. Our home is a John F Long home built in 1977. It was a very difficult task to find a competent HVAC company to do the difficult re-engineering of our system. I finally found Desert Diamond Mechanical. They had to move intake and take supply to wall not an easy task to engineer or install, but they came through and knocked it out of the ball park!! I had the pleasure of working with Rocky at the onset- On to Ben to determine if design would work properly, then onto the crew that helped Ben with install- David, Frank, Austin, and Wade. It went very smoothly and works fabulously. Ben really helped relieve my stress of the whole thing with his fun sense of humor. It turned out beautiful and works wonderfully! Thank you Desert Diamond Mechanical, Tamara W read more

My husband and I are so pleased with everyone at Desert Diamond. Justin came to do our yearly inspection and noted that there was a leak and the air conditioning unit was 20 years old. He presented the facts and no pressure for us to decide at that moment about a new unit. He was so polite and respectful. We appreciated that so much. We called and spoke to Melanie in the office and she was helpful getting us set up with financing and making sure we understood everything involved with the purchase of a new unit. She was so nice! JC & Alex were our installers and they were so amazing! Everything was concise and everything we needed to know regarding the new unit was explained perfectly. They both were also so respectful, kind and polite. Everything was spotless when the job was complete! We are so grateful!!! Thank you so much, Linda and Mike M. read more

When I called Desert Diamond I requested that an AC technician troubleshoot a recurring problem with my AC unit. As the outside temp increased to 100 deg , the compressor would shut off intermittently and the air handler would continue to work. Mario, the AC tech, arrived yesterday afternoon and most importantly he LISTENED to my description of the problem. When he tested the unit's capacitor he noticed an irregularity that was only visible for a few seconds and then its functioning was back to normal. With no pressure placed on me to purchase a new capacitor, he indicated that it could be contributing to the problem. I authorized replacement of the part. The result was amazing. The home is cool, the AC compressor is working well and I'm a happy customer. Thank you Desert Diamond for hiring this competent technician who listens! read more

Ismail came out to do an annual inspection and did a great job. Very professional, thorough and respectful. Since we started utilizing Desert Diamond Mechanical we have had nothing but great experiences. Outside of the occassional sticker shock of AC repairs (not due to service charges but cost of parts and refrigerant) and by no means any fault of Desert Mechanical. Covid and supply chain being the main culprits. Anyone that lives in AZ and keeps their AC in optimal working condition knows this just comes with the territory...lol! All that being said, Desert Mechanical is a highly reputable company and we have always been completely satisfied with their service techs, their service, and their prices. If your looking for a good reputable company to service your heating or cooling...its hard to go wrong with Desert Mechanical. read more

Hi everybody, I live in AZ . Last thursday my 15 years old unit completely shut down.Me and my familly spend the night in horror.I was wondering what to do especially considering it was a 3 day holiday weekend. I make a couple of phone calls on the 4th and Desert Diamond Mechanical ROC # 276814 was one of them, to try to get an estimate. Debby from DDM made my day right after she answered the phone, not even an hour later Steven was at my door. He found me the best deal and save me at least 2K and offered immidiate portable collers. Obtained financing and really put my mind in ease. I have my new unit installed already and I would reccomend DDM to everybody. They are a small family owned company and they are not going to rip you off. They go above and beyond to provide excellent service to their customers. Thank You DDM. read more

We had a severe problem when another a.c. company came and pulled a fast one on my 85 year old mother in Sun City. They took her perfectly good a.c. unit off her house and put a new unit up at $11,000! After a month of arguing to come and get it I had talked to the company's managers about what needed to be done. I was told it wouldn't happen but after talking to corporate managers they came and got it. I called Cody and he came out and gave her a quote for approximately half the costs. The same day they came and removed her over priced unit desert diamond was there and started the process off installing her new unit. I do believe it was Rudy Robert and wade that did the install. Thanks you desert diamond for helping me out with the problem. Great service and great people. I highly recommend them for all your HVAC needs. read more

As I said before, I met Desert Dimond Air Cooling & Heating about 10 years ago. I was very pleased with their technicians and how they conduct their business to solve people's needs. The technicians are so professional, well explicit, and friendly. This time, we had the fall A/C unit checkup. It was sent to our home young person pleasant and polite. His name is Phillip Lopez. He is punctual and professional, knowledgeable, answering all our many questions, Not to exclude friendly. We appreciate the service he applied to the unit making it run and look brand new. That would accurately express our gratitude and appreciation for this company. Hopefully, we will see him again in 6 months. Thank you, Phillip Lopez! Thank you Desert Diamond for hiring pleasant, friendly, and knowledgeable technicians. read more

The Way Cool Plumbing & Air team did such an incredible job installing not one but TWO new AC units…read more& TWO new furnaces in our home in North Phoenix. Chris and Kyle both were integral in getting this project taken care of for us. We were nervous about the cost and getting the units installed but the team worked with us on both those concerns. They were understanding of our budget and were creative in finding a way for us to stay within our comfort zone. Also, they were quick to get the units installed. We were concerned that we would be without AC for a week but Kyle was able to get us on the schedule a day later! Jorge and his team doing the installation arrived right on time and I really appreciated the e mail & text notifications of who each of the installers were that were entering my home. They were very tidy and thoughtful with the installation and from what I can tell they did an incredible job! Our house is nice and cold! I would totally recommend the Way Cool team if you have any AC maintenance or need a new installation! Thank you Chris, Kyle, Jorge and team! We really appreciate you guys!

Then Jorge and Jeandro came in and put in the real work--about 10 hours fixing issues that dated back over 50 years. Not an easy job, but they handled it with professionalism and attention to detail the entire time. "True service isn't just showing up--it's solving problems the right way, no matter how big." Really appreciate the effort and craftsmanship from this team. Highly recommend.

Requested a free estimate for potentially replacing my AC unit. AZ Perfect Comfort called me back…read morewithin an hour and scheduled with my tenant to look over the system. I received multiple options and competitive pricing for the units and warranties. I ended up repairing my unit rather than replacing it for one of the parts being under warranty. I wouldn't have considered this unless their awesome and thorough Technician Ryan Hoyos, had given me his honest opinion regarding the unit. I will gladly consider using AZ Perfect Comfort in the future and highly recommend due to the excellent customer service I received!

When the AC failed again a week later, I called them back, but they couldn't send anyone until the following day. Instead, I called another company, which arrived within 30 minutes and identified that the actual issue was a faulty thermostat. They confirmed the "white wire" AZ Perfect Comfort had pointed to wasn't even connected to anything. I am relieved I didn't pay AZ Perfect Comfort $240 to "fix" a non-existent problem. When I requested a refund for their $99.95 diagnostic fee, they refused, so I have disputed the charge with my bank. I strongly recommend avoiding this company.

Came back to us and let us know the unit was 16 years old! He explained in detail what repairs needed to be made and what that would cost in relation to a new unit. He even personally called the home warranty company to negotiate the buy-out price on our behalf right on site. We discussed financing options (they have a few). We ultimately decided to replace the entire unit. The installation team came out at 6:30 am, just 48 hours after making our decision. Brian and Oscar were so polite and professional. Once the new unit was installed, they came in and even fixed our thermostat mounting that had come loose. Shortly after the new unit was running...it quit. They came in to tell us the bad news, BUT they had a new unit on the way, and they stayed on-site the entire time. The new unit arrived and was installed quickly. Cody had been very responsive during the entire process. These guys were great! They went through every detail and completed the job with a smile. :)

It's rare to find someone so willing to educate their customers! On top of the great education, the price was extremely reasonable. I was also happy to learn that they handle Air Conditioning as well, making them a great one-stop shop for home comfort. I'm genuinely looking forward to working with this company again, especially Jacob. Keep up the great work!
