Best Maintenance Heating in Phoenix AZ

Dan waun was able to fix my issues, was very polite and respectful of wish all employees were just like him thank you for your work

Frank was out here on time, explained everything about the work he was doing and was more than courteous. Highly recommend Frank!

Had issues with our Nest thermostat not receiving power. The tech, Josh, determined it was the transformer and had it replaced in less than 30 mins. Josh has been out to our place before for our previous unit, and he’s the man. Communicative, efficient and professional.

Ryan was wonderful! He flushed the water heater, check the water coming in from the street and inside the house- Both the pressure and the softness. He was polite on time and the report was thorough. I’ll definitely recommend him to others. Thank you Ryan!

We were very happy with the whole installation process. The crew and supervisor were very communicative from the beginning to the end. No complaints here! very clean and neat. We are very happy with the variable speed heat pumps and the I-wave. Everyone in the family has said their allergies and asthma have dramatically improved. I only wish I had done this sooner. Thank you Jim Reed and Ramon.

I called Desert Diamond after seeing their great reviews. One of our AC units quit working and they were able to send a Technician within two days. Dontre arrived exactly on time, he was extremely courteous, very professional and great to work with. He quickly diagnosed the problem and was able to fix it right away. I would highly recommend Desert Diamond and won't hesitate to use them in the future. Our AC units will need to be replaced soon and my first call will be to them. --Dave

Never used however on 12-16-2021 a received call from Ella trying to schedule an appointment claiming they were raising money for some charity. Tried to explain to her I was on National Do Not Call List and she kept telling me I was rude over and over again. If I tell you I am on that list simply hang up however, to appease her I told her to come on out to service the following day. She continued to call me back asking for more information even after I told her I was on that list and I also told her I was at work and didn't have the time to answer a ton of questions. I finally had to block both numbers she was calling from so she would finally stop calling me. She is in the service industry (or a scam) and this is how she gets new customers by being rude. Hopefully, her calls are recorded for quality assurance purposes so the owner can listen. I would NEVER use a company that treats people like that and they really need to verify that Do Not Call List before they cold call people as the company can face hefty fines under the FTC guidelines. If I receive another call from that company I will turn the company over to the FTC as I am sure I am not the only person Ella is calling claiming to be raising money.

Promise Heating And Air do a outstanding job! Very happy with their work and customer service. Highly recommend them!

Mark was on time and courteous. I have a landscaping valve that I thought was leaking by with the system turned off. I was hoping this would fix my soggy backyard issue by replacing it. But that wasn't the case. Mark was kind enough to educate me on the landscaping system and tell me this valve is fine. He looked at my solenoid manual shutoff valve and turn that off. Paid the 89.00 service fee & sent Mark on his way. Here's to hoping this fixes the issue temporarily until I can find a good reliable landscape repair company.

Jared was courteous very informative polite welled manner

Having been taken to the cleaners by a well know AC company here in Phoenix, I reached out to A & M Mechanical. They went above and beyond trying to help me locate my warranty, dig into the details and bring clarity to a confusing situation. I appreciated the honesty and integrity of this company and look forward to using them for all our AC needs in the future.

CHASE DID A GREAT JOB AND WOULD RECOMMEND VALLYS BEST TO ANYONE WHO NEEDS HVAC WORK、

Very professional, great job. Matched the lowest estimate I had. Excellent.

Such great service and technician was so great.

The repairman came out quickly during the busy season and was able to diagnose the problem. The company quickly turned around quotes on various ways to proceed forward. Unit was replaced and the entire crew was polite, efficient, and did an excellent job. I have recommended this company to several other people now.

I reached out to this company on a Thursday night and I had a new AC installed by Tuesday. What unbelievable service they provided. I had 2 other AC companies come out and provide estimates and Cactus Mechanical blew their quotes out of the water. Do not get a new AC without reaching out to them and save yourself thousands.

Another company left me hanging on a Friday, so I called Day & Night. They arrived on time Monday morning, communicated well with me, and installed it quickly, for my disabled tenant who had no heat, due to old furnace. I really appreciate their good customer service and professionalism.

I love this company!! The workers were so nice and professional. I have small kids and pets in my house and we cant handle this heat. They came out and fix the air right way.Thank you guys your the best.

Josh was very professional and hard working.

Great service. Thorough inspection to make sure everything was running well. Will be using them again.
