Best HVAC Contractor in Phoenix AZ

This company is top notch. I took a chance after seeing their coupon in the Valpak, and definitely did not regret my decision to use them. When my AC broke they came the next day to fix the issue, unfortunately for me I got another leak a week later. One of their techs came out to assess the situation, and see what was happening and to check if the fix was still under warranty. It wasn't, but he was very honest about the options and gave me the best deal possible. They never tried to force the sale on me, or make me purchase something I didn't need. And when I did decide to purchase a new unit with them, they were nice enough put my original payment towards the purchase of the new unit to try and save me some money. They perform quality work, in a timely manner, and they clearly care about satisfying their customers. I highly recommend Desert Diamond if you have any AC issues.

Adam was on time, and handled him self in a very professional manner. He is extremely knowledgeable and quick. He solved our drain issue much faster than we could ever do. It was a pleasure to have Adam answer our service call

I have used this company many times. You can’t go wrong with this company. They are always on time and completely honest. The work never has to be re done. I went through countless HVAC companies before finding them and I won’t go back. Val was the last tech at my home and he was on time, professional and very honest.

Great company, good service, very professional and the price
was right. Will use them again.

Very happy with Day and Night! Greg is a fantastic technician and person. Professional, honest, thorough, kind, and knowledgeable. He is a pleasure and I look forward to having him help me in the future. Day and Night is a fantastic company. They get all my business! The Best!

Excellent service visit. Helpful recommendations.

Rising Sun made me feel comfortable and that I wasn’t being taken advantage of like the previous HVAC company. Brandon, service rep, did a thorough service call and walked me through all the issues, testing and options and then Pam, office mgr, did the same. I’ve heard excellent things about Adrian, the owner and the company, so I am going to be using Rising Sun from here on out and would highly recommend.

Highly recommend! 10/10!

Our service provider Thomas was amazing. He was efficient, cleanly, and informative. He truly took the time to help us out with understanding all the things we need to lookout for.Highly recommend Thomas as your plumbing expert!

Great company, Fernando has been excellent knowledgeable, personable.

Aguilar AC did a great job. They got to my home within an hour, and within 30 minutes had my AC working again even though it was 9:30p at night. Thank you for your professionalism and being more responsive and faster than the name brand places. I will definitely be using you for annual AC checkups.

This company really goes the extra mile! I’ve used them for my own personal property and for ones that I manage. They are very professional, very competitive pricing, and do a fantastic job! And…. They stand behind their work 100%. They make me look good when I refer them so that’s great too

I had a great experience with Guadalupe AC Repair when I needed to have my thermostat repaired. The team was professional and efficient, and they provided excellent customer service. The technician was able to identify and fix the issue quickly, and my thermostat is now working perfectly. I appreciate their attention to detail and would definitely recommend Guadalupe AC Repair for any thermostat repairs.

Brandon was amazing- quick, professional, and efficient!

Gerald and his staff are extremely friendly and professional. They installed my new Trane HVAC last week and they did a wonderful job and I’m a happy camper!

My A/C which was over 20 years old was having mechanical issues so I contacted an A/C company (you know the well known company in which the Techs wear white uniforms) to access the A/C. To cut to the chase the Tech gave me an outrageous price to repair the unit and even a more outrageous price to replace it with (after my research) a subpar York A/C.
A friend told me about ABC Air Conditioning so I contacted them and the owner, Tom Smedley came out, free of charge, to access my A/C unit. While accessing the A/C Tom did at no charge a temporary fix on the mechanical issue, WOW!! I decided my A/C served me well but it was time for out with the old and in with the new. Trevor Smedley provided me with all the information I needed to make my choice. Trevor and Tom than came out to personally discuss and advise me. After discussing my options I decided to purchase a 3ton 16seer Trane unit. I did my research on Trane and Trane is rated #1 when it comes to customer satisfaction and Quality. Within a week of my decision the new install was complete. Tom was at my home personally supervising and ensuring a quality install. I will continue to use ABC for bi-annual check ups of my unit. ABC saved me thousands over that other company and just made me feel comfortable working with them. Great decision on my part!

It got really cold in Arizona which I didn't think would ever happen. Turns out my furnace wasnt working which made the family pretty unhappy. I found Accutemp online and they sent someone out immediately and fixed the furnace and now my home is warm and toasty. I appreciated that the technician didn't try to upsell me on anything but when I do need a new system I will be calling Accutemp.

They did a great job. Would hire again.

Great techs and fast service! Always a pleasure to work with these guys.

The ACA Installation crew was on time, worked efficiently, answered all questions, found and fixed wires not connected at the factory, and finished early. What else could anyone ask for?
