Shout-out to Diamondback Air for a job well done! John (owner) and his tech Chris responded to our residence after a power surge caused our A/C unit to go out. The capacitor blew and the electrical line melted at the shut off. All are now fixed and some other parts are upgraded. Runs like new! ..... Thank you!!!! read more

Will never do business with this clown show again. The owner has excuse after excuse after excuse after excuse. Then, they don't take accountability when issues are brought up and we do exactly what we are told to do, then they blame and shame us for the bad unit. Save yourself the trouble and go somewhere else. read more

Showed up a little later than expected. But came in and knew what needed to be fixed right away!

Diamond Air and John had great communication and fast response time. We are happy to have air back on, especially in this heat. read more

Diamondback Air - Heating & Air Conditioning/HVAC Near Me

Simply stated, Diamondback Air handled my HVAC emergency with integrity, kindness and expediency. Without any hesitation I would recommend service with this organization. I genuinely appreciate the level of honesty that was able to discern throughout the experience. Was recommended from a neighbor who appreciated the owner's trustworthy approach to delivering essential services in a timely and equitable manner, and am 100% a lifetime customer moving forward. Very thankful. read more

Shout out to Heather for reaching out late last night with my AC issues. Kind and considerate, provided the owners direct number to get us scheduled. He arrived on time (actually ahead of schedule), popped the unit open, took one look and discovered the issue. Let me tell you, it was an honest relief to have an honest "this is the problem" and fixed it within 15 minutes! No upselling, no bs - just this is all you need - a wire to be reattached to the capacitor! He even installed the two new breakers that I was sent to purchase from HD by the previous company only to be told - no, you need a new unit. In the end we all want a company that is honest, fair and will do the right thing. Diamondback is that company - you cannot go wrong with them. read more

We have had a very good experience with these guys, and would definitely recommend them to friends and neighbors! We had our system checked back in November with reasonable prices, and professional and efficient work completed by Oscar. Of course when it became really hot this past weekend, one of our systems was not cooling properly. I called John, the owner, and he and Chris came out on Saturday. Assessed the situation, told us what was needed, and corrected the problem. He gave us some good advice, recommended a system that will assist in cooling our home better, and we've been very pleased with the results! Thanks Guys, you ROCK!!! read more

Update 8/31/19: A true testament of service is how they respond when issues arise. On Labor Day weekend, our unit stopped cooling and owner John personally arrived trying to diagnose and resolve issue. John had contacted warranty ready to replace compressor or unit, if unable to fix issue. When he came back with new unit and compressor, John went through steps to diagnose root cause and was able to resolve issue and fix immediately. John stress tested unit to ensure issue was resolved. Temperature inside house was 86 degrees and decreased to 79 degrees 90 minutes later and a comfortable 75 degrees at night. Unit is working better than ever. We appreciate John's expertise and commitment to taking care of his clients (even on holiday weekends). read more

Customer service was outstanding! We are very pleased with their work! Hard working crew! The owner John went above and beyond for us. Our new AC unit works great! Thanks again John! read more

Our air conditioner went out on only a 103 degree day but still hot. John came out to evaluate our situation and found the compressor was burnt out. He gave us a quote and timeframe which was the next day. John & his team did a great job getting the air conditioner replaced within the time frame and budget quoted. We appreciate the quick response and quality service provided. Excellent job guys!! We appreciate you!! read more

Our air conditioner went out in the heat of August. I texted John, sent him a few detailed pictures of our old unit and connections. He graciously texted back that evening with an overall preliminary plan and estimate. He was the only one out of the three quotes we received that was able to have our new unit installed and working within 24 hours when the others needed a week. John is an expert in his field and we appreciate all of his direct and honest communication. He also made sure all was up to code and looks great! Thx, John. read more

Unfortunately, my AC unit stopped working recently. I looked around for a local fix. John (the owner) came out within an hour and had the ac working in no time. He took the time to educate me on how the whole outdoor condenser unit worked. I really appreciate the effort John! I will be recommending him to all of my friends and family! read more

What a fantastic company. After some initial communication hiccups, John (Owner) and Julian (Senior technician) did an amazing job of diagnosing our problem, and fixing it in a cost effective manner. They are knowledgable, trustworthy and a company that keeps promises and does everything they can to make it right. I would recommend them to anybody. Thank you Diamondback air...... read more

Remember your van is a moving build board. You may want to refrain from weaving in and out of lanes and driving at least 85 because you flew past me and I was doing 75. Your driving certainly wouldn't make me want to use your company when you clearly have aggression and/or low tolerance issues. read more

They installed a new compressor and air handler that has been mostly inoperative since January. Another company found poor workmanship in the wiring of the air handler and a leak in he refrigerant lines. I have filed a complaint with the Registrar of Contractors as Diamondback is non responsive to service a 8 month old new unit read more

After extensive searching of google and two other companies no-showing I found this company and so glad I did! I needed someone to come out as soon as possible. When I first placed my call I was told the owner would call to schedule. Within a matter of minutes I received a phone call from the owner, John who assured me he would fix our problem and be out tomorrow (today). John has excellent customer service and communication. I received a confirmation text last night to confirm my appointment. A text prior to the arrival. John and Chris arrived on time as promised, quickly diagnosed the problem and fixed the issue. This company is honest, reliable and will fix the problem without trying to "upsell". Thank you Diamondback Air. I highly recommend this company and will use them in the future if needed. read more

I own a property in Tempe AZ. The thermostat gave a message that the air filter needed to be changed. I gave the tenant the name and phone to Diamondback Air since they were on the internet as a BBB member. The guy came out, reset the thermostat and told our tenant how to change out the filter. When the tenant asked him if he was changing out the filter he said no because he did not have that size and charged $89. I called the phone number and they said they were sorry but that I would have to call back some other time because that was a service call number and there was no one there that could help me. This place is pretty bad. read more

I had diamondback air out on Saturday and was told I needed a new fan installed. Since my hvac unit was actually still working we asked them to come back Friday morning so we could go run some errands that afternoon. They confirmed the technician would be back today at 6 am to install the fan and clean the condenser coils. The technician did not show up at 6am, so I waited 20 minutes to call the number on the website. When I called no one answered so I left a message. It is now 7am and still no technician and no call back. I do not recommend anyone use this company. read more

John saved me today! Not only was he friendly and professional, but he fixed my heat in no time. He was here exactly when he said he'd be, which was only hours after I called on a Saturday! I recommend Diamondback Air to anyone! read more

Just had my first experience with Diamondback Air. As a property manager in AZ, I work with a lot of contractors and I am overly impressed with this company. Within hours the owner was helping my tenants get their A/C up and running because their baby had a fever. They really do care, and honor their work. They will be getting much more business from me in the future. read more

Would love to give them 5 stars because the result was fantastic, but getting there was a chore so I can't give them a perfect score. They care about the work they did and my new system performs really well (my house gets cold and does it fast). I worked with John and Kevin (I think they are co-owners) and was thrilled with the deal and warranty they worked out. When I say the install was a chore, I mean that they were constantly late, the install went days over schedule and there seemed to be drama at every turn. In retrospect I believe the drama and extra days in the cycle were a result of them making sure things were done right and appreciate that they kept showing up until the job was complete -- not just slapping things together and moving on to the next job. I feel like a got a better product, a better install and a better price with Diamondback, but had to overlook a couple of things on the customer experience front in order to get there. read more

Great job by Julian - prompt, professional and on time - this guy is a pro and the Diamondback guys have done a great job for us over the years. Good follow-up and really push to get the job done when you are cooking! read more

I was lucky to make contact with John Herman of Diamondback Home Services again. He installed some great Amana AC units in my house 9 years ago. Unfortunately I lost track of John somehow and I contacted another company to do annual maintenance. The other company didn't know the Amana brand well and "repaired" the units with costly add-ons that weren't needed and actually seemed to cause a problem with the communication between the units and the thermostats. John and Mark had to properly cleaned both units and quickly identified the problem caused by the other company. They fixed the issue with original OEM parts and the units are working great again. I highly recommend John for his product knowledge, professionalism and great service. read more

My experience puts me in a rather unique position to recommend Diamondback Air. Roughly 8 years ago I had two successive nightmarish summers with multiple air conditioning outages. American Home Shield, my homeowners insurance company, sent a series of marginally competent air-conditioning companies to correct my cooling issues in a unit that was only 7 years old. Extremely frustrated, I opted to buy a new, high-efficiency, 5 ton Amana unit from Diamondback. A friend had recommended them. Pleased with installation and the performance of the new unit, I had occasion to recommend Diamondback over the next couple of years to 2 friends. Both employed Diamondback and were pleased with the results. A little over 6 months ago, in the middle of the summer, I moved a short distance in Mesa to a larger house. There were 2 functioning but ancient (17-18 years old) heating/cooling units. Given my horrendous experience 8 years earlier, I decided to replace them before anything could go wrong. I chose Diamondback again because of my past experience. They installed 3 ton and 5 ton, high-efficiency Amana units. Although it is too soon to measure the anticipated decrease in my electrical bill-I did save 20% on my bill in my old house, installation and follow-up were flawless. And to my very pleasant surprise, one of my units-they were functional, after all-was placed in the home of a lady with terminal cancer and no air conditioning. Apparently Diamondback responded to an SOS from a health agency and performed the installation without cost to the lady in question. My experience with Diamondback, at all levels of their operation, was already so positive that learning about their generosity in this specific case could not have pushed my opinion of them any higher. But it was nice to know. They do an exemplary job and they care that their customers are happy with the results. Lester S. -Mesa, AZ read more

Diamondback Air is quick to sell you a brand new system, but to get them out to repair it is another story. Excuses galore, never on time, you are expected to wait for them regardless of what time they show, and instead of phone calls, text messages! Very and totally unprofessional! Do not use these guys, as its a total frustrating experience. They have honored their warranty thus far, but be advised, warranty work is their very last priority. Our system, a Goodman DSXC 16, a 4ton split system with gas heater was installed last year after I was told our 7 year old Trane was not worth fixing. I knew with R22 becoming more expensive and going away in 2020, it was a pay me now or later thing. Incidentally, quote for a new compressor, labor only as compressor would be under warranty from Trane was $3,000.00. Very high price I found out later. No a/c, we were hot etc, I made a terrible decision to replace and use these guys to do it! Real quick to install I must say, but I also paid $7,001.64, and they never waited on me for payment, they had their money before install was complete! Last Friday, after a power outage, this new system went out. Over the phone with the owner he talked me through replacing fuses, pulling a capacitor, testing capacitor, replacing capacitor etc only to diagnose a circuit board as the problem. Was told they would be out Sunday or "Monday morning at the latest" that's a quote from the owner John. Never showed until after 6 pm Monday, Chris replaced the capacitor, and circuit board on the condenser unit, also a fuse on the air handler. System came on, Chris left. 2 hours later, system stopped cooling, back to our 100 sq ft spare room with a cheap 5000 btu window unit that's 7 years old, cost 85 bucks and blows cold. Spend 7 grand and don't even get a year of cold out of it. Ironic. Called again, was told Chris would be out Tuesday, no show, was told he'd be out Wednesday, on his way, be there soon, etc etc etc. told he was involved in an accident, would be first priority Thursday morning, be there by 9am, no show no call so unprofessional. He finally showed Thursday evening. Replaced thermostat, system on. 3 1/2 hours later, quit working again! Chris had to call Goodman to figure it out. 1600 share foot house, me my wife and 2 large dogs are in 100 square foot bedroom now for 1 week! Friday told another circuit board for the air handler heater unit inside was ordered, he would be here between 12 and 3 to fix it, was called by Chris at 1:30, part not there but on the way, he would call when he left, nothing until 830pm when he said he would be at my house by 8 am Sunday. My wife waited all day Saturday for no reason, could've gone to the valley to get away from our hot house, she's upset now. He finally showed up at 3 pm Sunday system on at 355pm and hasn't stopped yet! I believe it's been a thermostat problem from the get go, but I'm not comfortable and confident in this system. All this deception, lack of communication to their customers is a direct reflection on the owner John. Too late for me, but read all the reviews on these guys, there's a few good ones, but for the most part mostly bad and mostly because of their promptness. If you say you're gonna be there, you better be there! If a customer isn't home, you will leave. read more

Have you EVER been called by a technician at a company and berated for complaining that twice they No Call/No Showed for scheduled work? This happened to us courtesy of Chris at Diamondback Air. Have used them exclusively in the past with all good experiences. Last time was 2013. they failed to show up/call with an explanation or offer to reschedule on July 1st for a repair that was not an emergency. After we called and spoke to Olivia she insisted they would show up on July 3 between 9-10 am even though it was Sunday. Once again no contact, I called and left a message upset this happened the second time. 30 minutes later we get a call from Chris yelling at us that Olivia was doing the best she could and this job required 2 technicians. So why was it scheduled for a Sunday? We told them we were done with Diamondback Air. read more

Our experience with Diamondback Air was great!! The owner of the company, John, and his technician, Julian, came out to our house the same day we called them. Their prices are very reasonable, and they are professional and helpful. Diamondback Air got our A/C back up and running much more quickly and at a significantly better price than other estimates we received. We are very impressed with their company and will definitely be repeat customers in the future. Thank you, Diamondback Air!! read more

I had them install a new system which I love. I had a few issues recently with access to the attic however Mark and his partner came and solved the zip tie issue that prevented me from using my attic opening. Over all I am once again with the service. read more

They came the day I called, and fixed our AC unit the next morning. I have owned 3 homes in the 15 years that I have lived in Arizona and Diamondback Air has been the only company that I have ever had to call, they always take care of me. I highly recommend these guys!!!! read more

***Skip this company- Try someone else *** 100% Real and 100% true review I was a 1st time actual customer and will not call this company again. Reasons : I made an initial call and setup an appointment (This company did not show and did not call) on agreed time (Only when i called them) did they tell me that they had to reschedule. a 2nd appointment was setup for a Saturday (again) This company was a NO show and No call (again) only when i contacted them again did they apologize and again said they cant make it and a 3rd and final appointment setup (next day Sunday) 8 TO 10 AM , On this day they did show up but at end of agreed time 10 am ( after 3 attempts) I got an estimate 6,000 to 6,500 to replace the Air conditioner. At this appointment i was told i would get an e mail with the quote (quote not given at appointment but was told would be e mailed to me) The next day Monday (NO E MAIL received ) again only after I called them did i get the quote and it was higher then what they said as well(no surprise there) so why did i go through all that ? it was also because i needed financing assistance and they did say they had an inhouse financing program , so I applied and I was told to get a NEW AC UNIT I would have to pay 50% DOWN UPFRONT which is was like 3250 dollars down.. No Thank you....I advised them Declined Save your Time , Try another company..... read more

If zero stars was an option this would be the most appropriate rating. This is a nearly four week ordeal to fix an air conditioner peppered with extremely poor technician service, lies, and no success in fixing air conditioner. Run to anyone else!!!! read more

In September 2009 our A/C unit stopped working. I called a few companies, including Diamondback Air and talked to the owner, John Herman. He was very helpful over the phone so I agreed to have his technician come out the next day to take a look at my unit. When he arrived he determined that the fan motor had seized up and needed to be replaced. Luckily, it was under warranty so it should have been a quick and inexpensive fix. The technician called John for a quote and he quoted me $485. $485 to replace a fan motor that was under warranty and would only take 30 or so minutes to replace! And that was on top of the service fee I had to pay. I immediately called John myself and he gave me some song and dance trying to justify the ridiculous cost. I told him I would hire someone else. I paid them their $70 service fee and sent the technician on his way. I immediately called several other well known reputable companies and got quotes over the phone to replace the motor. All the quotes were SEVERAL HUNDRED dollars less than what John had tried to get out of me. The next morning another company came out and replaced the motor and was in and out in under an hour. They charged me $110 total. I'm just sorry Diamondback Air got $70 of my money. In my opinion, John Herman and Diamondback Air have shady business practices. I don't know if John felt he could prey on someone because it was hot and maybe I was desperate enough to pay the money to have my A/C work again or if it is because I am female and he thought I wouldn't know any better. Either way, I am disgusted by the whole thing. I also found out afterwards that their license was suspended at the time. I advise everyone to stay far away from this company. There are far more honest businesses out there that will get the job done professionally without attempting to rip off their customers. read more

We replaced TWO air handlers and air conditioners during the month of July 2013. Luckily we found Diamondback Air recommended from a friend or ours. John, the owner was very clear and provided in-depth information and recommendations. We had pretty much done our homework prior to speaking to him so the research and his opinion made our decision easy. The staff consisting of Dustin, Andy, Mark, Billy, Sergio were EXCELLENT! They worked tirelessly on very old 1984 systems and encountered several additional problems, leaking water, rust, additional sheet metal work and electrical work without a complaint....they simply fixed the problem to make it all work with no additional cost to us! Frankly, we did not think there was a company nor it staff left in American that actually did what they said they were going to do and did it well. It was a very pleasant surprise. The old systems were hauled out, house and garage was cleaned up and the two systems are working great. Could not recommend it highly enough. read more
