Best Businesses in Arizona

Donavon came to our condo to perform service on our HVAC unit. Did a great job, was thorough, very professional, explained the condition of our system, and the price of the service was a great deal.

Anthony did a great job. Was knowledgeable and friendly. Would like him again.

Mario is here now at 9:30 at night replacing the blower motor. I decided to purchase a new ac unit because of the age of my current unit. Mario explained all the options and presented everything straight forward. Nice guy, and seems very honest. I will follow up when my new AC is installed. Thanks Desert Diamond.

Always first-rate experts and technicians. Very thorough and professional and friendly.

Technician was friendly and informative. Went absolutely ABOVE AND BEYOND to help us figure out next steps for our unit. 10/10 service. 10/10 employee.

I don’t normally write reviews, but I felt the need to let everyone what a great job Nacho and Mario did at our home. They went over and beyond making sure our system was running right! Thanks!

Always great communication, on time, and very professional. Have always done great work for us.

Mark and Amy are awesome! I did a lot of research to find an A/C company that I can trust and did I hit a home run with A&M Mechanical. They did a great job, were timely and their attention to detail was great.

Just wanted to let you know that this adjustment for the a.c. turned out perfect! I actually have a constant temperature throughout my home finally! I wanted to tell you (and the whole company) thank you so much! This has been bothering me for a year and I didn't have 3 grand to fix it (which is what the other company told me it would cost) but not only did you all manage to get me exactly what I wanted, but all for less than $800! Thanks again for everything!

Klein Heating and cooling technician was extremely nice and really explained the size of unit I need like no one else did. Work was very professional. The price was the best quote I had and I was totally surprised when he finished the job that he completed a significant amount of duct work that no one else offered. Even if it takes a while or some effort to schedule a job, I would highly recommend you use them because when the work is done you won't be disappointed.

Pleasant experience with minor hiccups but issues were resolved two days after installation. Friendly employees. Overall good experience.

I had a seasonal maintenance done and when I complained the air flow in some of our ducts were bad Jorge and John came back and fixed the problem by straightening out the flows to the ducts. They had been kinked. This corrected the problem. Great team and deserve an A++.

Prompt, knowledgeable and most important willing to take a few moments to describe the tasks performed. Excellent experience.! Highly recommended.

Great experience. Fast service.

My A/C broke and it needed to be replaced I called King mechanical the owner came to my house in 30 minutes he gave me an amazing deal on a new A/C unit. The installers came in record time and installed the new A/C unit. This is a wonderful company I am extremely satisfied with there work. Friendly professional and reasonable prices. I would highly recommend this company.

The team was on time and very efficient. After the work was completed, I was provided a thorough report on everything that was done and a follow up call to touch base. It is really great to receive that amount of communication and information so we know the exact status of our equipment.

Great service! Very nice tech.

Response time was amazing! Price was $2000 less than a quote from another HVAC Co.

Dan installed my system 3 years ago, and maintained it. Most people including the owners are VETERANS like myself, and their work shows it, OUTSTANDING
