Best Heating & Air Conditioning/HVAC in United States

There is no other HVAC guy I'm calling than Tracy with J & M Mechanical. He's responsive and great at what he does!

Called Brian on a Saturday with an emergency AC issue.  Even though they were booked up, he fit me in.  Axel arrived within a few hours for a diagnosis and stopped the condensation leak.  He gave me great advice on repairs needed, and although I didn't want to spend the money, I appreciated that his advice would prevent future leaks.  Great service!  Great response!

Very pleased with the stellar customer service provided by Matt who responded within minutes to my voicemail message. He then took the time to educate me on the possible issues my system was having, then provided a more-than-fair estimate over the phone which was half the price a more popular big box HVAC company quoted me who I had originally consulted. His tech, Oscar, showed up on time with a Can Do, Will Do attitude and didn't try up-selling me on parts or services I didn't need, nor did he try high pressuring me into an annual service agreement (unlike the company mentioned above). Oscar was quick yet thorough in his workmanship, and had no issue answering my questions and giving me money-saving advice on things I needed to repair immediately as well as things that could wait. During the repair, Oscar realized the part he needed wasn't on his truck so he immediately tracked down another tech who delivered the part to my house within about 20 minutes. Due to the honest, prompt quality service I received, I plan to be a life long customer. My A/C unit and furnace are past their prime, so when the day comes to replace them, M&R Refrigeration will be my first and only call.

CW is a legit operation.  

It's been 2 years since I've had my ACs serviced and wouldn't you know, the Friday before a record heatwave of 117 was coming our way, one of my AC units decided it would be a good time to quit.

I called a trusted friend of mine to ask what company she uses to service the ACs of her rental properties here in town and she responded right away with a referral to CW.

Mike was dispatched within 30 min (I couldn't believe the response time) and spent time with me to diagnose the problem and explain to me the ins and outs of what he was doing, why, what to expect etc (I always have a lot of questions).  He fixed the failed capacitor in no-time and gave me an affordable bill for the service.

These are my go-to guys now for anything HVAC related.

Thanks CW and thank you Mike!

Mitch and Cary were on time, courteous and professional. We had them service our unit and fix a thermostat that we installed incorrectly. They were completely receptive to our new social distancing rules. Overall it was a great experience!

Jimmy the owner got a hold of me right away after I submitted a request for a new A/c unit. Every step of the way he was professional and super helpful. They came out and did an amazing removal of old unit and instal of new unit in a short time. I rarely review anything but these guys are the real deal! I highly recommend them!

Company came out quickly and gave me a free and thorough estimate of a project. Seems like a well run company.

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!!

Highly recommended for Cooling and Heating services! I just had a complete new system installed and I couldn't be more happier. The process was easy from start to finish. The prices were great along with the service I received. Personable, professional and reasonable.

On the hottest day of the year so far wouldn't you know we would experience problems with eh  A/C (heat pump ) on the house, wife was extremely uncomfortable being as she was on the healing end of another surgical procedure . I called my Home warranty Company (Fidelity) and they called North Valley Mechanical . I talked to Kyle, then Kendra and they said they would have someone out later that day due to the circumstances with my wife ... Matt ( the Tech) showed up and got the unit to be operational but said the coil was leaking so it was a problem and they would contact the Home Insurance Co for them to okay repairs ... They (Glenda)  Fidelity said they were going to replace the until because it was over 10 years old and that if I paid the differential ($950.00) they would replace it with another Carrier 4 ton /14 seer heat pump ... I was advised this was not true and they would put a Payne Unit on as a replacement ...  Kyle from NVM called to make arrangements for them to come out and measure , then advised me that the Home Ins Co was going to replace the unit with a Payne Unit and that they were made by Carrier , I told him to hold off until I could get all of this together and gather some facts  ... I called Carrier and they said the only thing that was a fact is that Carrier owns Payne but nothing on that unit was the quality of a Carrier unit and the only connection was Carrier owned Payne , nothing more ... I was told by the Customer Service person from Carrier that the Payne Unit was junk ... I called NVM and told Kyle to hold off, I was not going to accept a piece of junk as a replacement and that I would contact the Ins Co ...  Jim (NVM) came out to measure and I told Jim its his company's reputation at risk by them putting a Payne unit on my house and he said they would not even do the job under those conditions , that their reputation was more important than this job under these conditions ... I called Fidelity back and we argued and fought until they got to a figure I would live with, not be happy with but live with .
 I called North Valley Mechanical and talked to Kendra, she said she was not sure they wanted to do the job being as I would be difficult to work for (Understand being as the way things started) ... I explained to her my position and if they wanted to they could bid the job, now that Fidelity was out of it all together ... Jim came back out and advised me I needed a bigger return ($240.00) and he specified a higher end unit made by American Standard  (Trane customer service said they and American Standard are basically the same and are higher quality units) ...  (4 ton/16 seer)  and gave me a total figure for the job ... He said I would have to pay the total amount in advance because thats the way they (NVM)  wanted it, so I wrote him a check ( he lost it) and I had to call my bank, stop payment and reissue another check the following day ... It appeared all was going well, they showed up the following day (Friday) to do the install and Jim (installer) and Ricard seemed very nice and totally knowledgeable about what they were doing . I watched from a distance as they went about their work and after they put the new return in I measured it and it was not the 18 inch return I was charged and paid for but a 16 inch which I was told was not big enough, he (Jim the installer) advised me they could not get an 18 inch return in there as there was no room .... I told the installer I was not going to accept it (16 /versus18) and he best get his Boss on the phone,  His Boss, Jim then told me that 16 inch was big enough, after he convinced me it was not and charged me for the up sized return from 14 to 18 inches and I expressed my  concern,  he said they would have to put a second return in ...  Jim came back to the house with another return (20x20x1) which could not be put where he wanted to put it because of the metal work that was there so they had to put it in the Living room which was fine as long as we had enough return for this unit to operate correctly .   I offered to split the cost of the second return with Jim and he would have no part of it, said it was on them and that it was because of a misunderstanding (?) , not sure what that was ...  
  I wanted this job to go smoothly only because of the way it all started out and once all was said and done it turned out just as it should be ... I would highly recommend North Valley Mechanical, but as with any and all contractors get everything in writing and expect to get what you pay for, nothing less ... Its only been a few days but we are happy with the job and so far, so good ... Put it in writing and hold them to it ...  
My Brother in Law happens to be in heating and cooling so he gave me some things to watch out for and what to expect .  
 If you have any doubts call the suppliers (Manufactors) and research things on the internet, it is your friend .  I am glad I did,  that I can assure you ...  .  Payne is not Carrier ...

Brett was great....super responsive, very knowledgeable and extremely professional, also very affordable for a service call.... he assisted me in looking at my unit to verify its current condition as I am going through a home warranty claim and wanted a second opinion...you can't go wrong with the Arizona A/C Man!

Miguel was awesome! He came out to my house same day to look at one of my units that wasn't cooling. He found that the last person to service my AC did some really sketchy stuff and he fixed everything up in less than an hour and my unit started cooling right away! Miguel was very knowledgeable and professional. I'll be using A/C doctors from now on.

Moved into a new home and needed some electrical work done. They finished in a reasonable time and the price was very fair. I'd definitely recommend them for my future projects!

A/C went out on a Friday night in early May. Freddy answered his phone at 10:30 and was going to head over to my house to check. Since it appeared to be icing up, we decided to have him come over the next morning instead.

Since I knew my system was cresting 20 years old, I didn't hold out hope for a repair and sure enough I was leaking coolant from many coils. It could not be repaired. And who sets aside thousands of dollars for a new AC system?

Freddy was professional and explained all the options. There was varying degrees of costs and Freddy never pushed any option. He patiently answered questions on each option.

His company offers Wells Fargo financing, so it helps in making a more long term investment rather than an immediate cheap fix. Given this, I opted to go with a 21 seer variable speed system. After researching they should offer the best energy efficiency and lowest monthly electric bills.

Everyone who is in this situation should get multiple estimates. I had 5 people come and give bids after Freddy. He beat all their prices and presented the most knowledge. A few contractors talked about tearing out my ceiling, leaving me with either drywall repairs or more costs to fix it. One even talked about cutting into my roof trusses to get the unit to fit - a potential structural issue as I saw it. None of these things happened with Freddy's install.

Freddy delivered the system on schedule and the install went smoothly and quickly. It was about six hours total. His crew was clean, respectful and quick. They knew what they were doing.

Since this was a variable speed system, it takes some getting used to. My old system was full on with a full blast of cold air and then off. This unit can come on really low and you don't necessarily feel a cold air blast. It's more like a light breeze. This difference highlighted some hot spots in my home, so Freddy came back out a few days later to adjust vents and air flow. All good since.

Other companies also used the power company rebate to make it look like you were paying less. Freddy gave a very competitive bid and I got to keep the rebate to add to the loan, if I wanted.

With any install, Freddy includes maintenance and tuneups in his price for 2 years. You can add more years to keep an expensive purchase in top shape.

This is an up and coming company that wants to do right by their customers.

Phoenix has a thousand AC companies so if you're like me, you don't know who to call or who to trust. What I appreciated most about Freddy was his explanations on things and his low pressure approach. His prices were good, but I'd have spent more if I hadn't gotten a good feeling on his business. You want things done right and if something does go wrong, you want someone who stands behind their work to make it right. That was my feeling on Freddy and why I opted to use him.

I used to North recently and their technician Johnny who did a terrific job for me I want I love you beyond to help me. He is the best!

Called Kevin at Four Seasons to do a pre summer tune up on my A/C. He was professional, prompt, thorough, and honest. He didn't try to upsell me for something I didn't need and was very reasonably priced. I do recommend you give Four Seasons a call if you need a service or any other kind of A/C work done.

The BEST COMPANY EVER! Not only that they came right away as I was in an emergency situation but they had to wait for numerous obstacles to clear (obtaining a code to get a key from property management, then key not working and waiting for a locks man) so they can get to the fire raiser room in my building. I'm so impressed and absolutely blown away by how much Al and Steve went above and beyond that I want to recommend them to everyone! It turned out that the motor of my A/C had burned out that it will take few days to order a new one. Well, I own a fitness studio and I couldn't afford to shut it down, so they went and bought 4 huge industrial fans, set them up and brought them to my gym! I CAN'T TELL YOU HOW HAPPY THAT MADE ME! Thank you Al and Steve and company for being so awesome without even knowing me!

AC went out at 7:30 this morning, Howard Air was answering phones at 7:45 am, they were here by 10:30 and had the problem fixed by noon. Joel, the technician was very professional and got our AC blowing cold! This will be my go to AC company. Service was exceptional and price was reasonable. Highly recommended!

I had Goettl out today to do a rejuvenation to my a/c unit. The technician was extremely helpful. My ducts were checked and he said my unit looked great. I was so afraid to be told I needed a ton of work. I have no hesitation to call them again in 6 months for another service check. Oh....and I got my flashlight! Yay!
