Best Heating in Phoenix AZ

Daquon was on time, did a amazing job with our water heater! He was professional as well-as Jessica who I spoke on the phone with was helpful and courteous. Would definitely recommend using this company in the future!

There was nothing to dislike from the start to the final installation.

Awesome company to work with, no pressure, honest pitch from salesman, Brandon. Tech’s worked clean and professionally. Would highly recommend!

Scott came out 2 hours early and was friendly, thorough, professional and all around wonderfully nice guy. I mentioned my dishwasher was flooding and he took the time to unclog a line. Could not ask for a more pleasant service person. 100+ bonus points for Scott!! Linda Marquis

Every time I need NVM, they come through. Excellent customer service, punctuality, professionalism, and dedication to their customers. I'll never use another AC company, and I can't recommend highly enough.

As the temps hit triple digits, I began thinking about getting an AC Tune up. The only question was who to use. I had received multiple fliers from various companies in the valley. Both of my neighbors had recently used Desert Diamond and had great things to say. I figured between the positive reviews, and the great price, why not give them a shot. I called and spoke to a friendly young lady who scheduled me for the next available time slot. I let her know that I had plans that afternoon, so if we could move it earlier I would appreciate it. She assured me that if possible, the tech Jason would call me. Sure enough, I received a call almost 3 hours early. Jason let me know he would be there in 30 minutes. EXACTLY 30 minutes later he pulled up. I can’t remember the last time a company was that punctual. Jason was incredibly kind and friendly. It is always nerve-wracking inviting someone into your home. However, he was incredibly clean and even wore the shoe covers (Sorry, not sure what the technical term is).

What impressed me most of all was what took place next. In my past AC experiences, the tech tells me what I need (supposedly) and I pray my wallet can afford it. It almost feels like a car mechanic and I always wondered “Is he BS-ing me right now”. However with Jason, he provided a comprehensive review of everything he inspected, showing me pictures of the readings and how they compare using industry diagrams. There was no car salesman up-selling. Simply a real conversation between the subject expert and a homeowner. For every recommendation he had, he provided a detailed explanation of why and when the work should be done. Living in a city with an “expert AC company on every corner”, it’s nice to know I finally found a company that I can build a relationship with. I strongly recommend you save yourself the time and money and avoid the other yahoos out there. Desert Diamond is the way to go.

E cellent service. Communicated clearly what service I needed. Reasinable cost.

Promise was amazing. I knew I needed to replace my AC system. I got several quotes. Promise asked the most questions, clearly made that extra effort to understand our needs, they explained their bid very thoroughly. Were fair and competitive in their bid. We chose them because you’re not just buying an AC, it’s years of service, it’s who do you trust to show up and take care of you?
On the install day they were on time, in uniform, everyone was clean, courteous, professional, and The whole thing went very well, smoothly, and they cleaned up after themselves. We are super happy with them, great team, great value, great people. Solid equipment with great warranty. Friendly and fair. What else can you ask for?

Q was professional and thorough with the maintenance of our heat pump. He took the time to do things right and made sure everything was running as it should. He fixed the problem we were having and made sure that we understood what he was doing. Will definitely keep with this company and the technician.

1st Choice came out yesterday to do our yearly complimentary AC check up ! We had a new AC system installed be them 2 and 1/2 years ago and they have excelled in every aspect ! Best HVAC company ever! Technician Manny Did a grate ob inspecting our AC unit! Replaced our filter! CH

These guys are the best! They have done quality installs on two of my properties for a very reasonable price. Their attention to detail and honesty are truly refreshing. Their ongoing service on my units continues to be priced fairly and the work is always done in a timely manner. They show up when scheduled, and if any additional work is needed they give a full explanation of all the options available.

I wish my experience was the same. I am going on 10 days with a broken ac and the company has become MIA and not filling their report as required. They have not reached out to complete repairs.

I had Klein Heating and cooling fix my water service upgrade this last summer and when I had a plumbing issue in my basement bathroom Klein Heating and cooling team were my first phone call. Exceptional work & better service. Can’t recommend enough. Thank you!!

Sun Devil Heating & Cooling came out within 24 hours when I could not get anyone else out after our air conditioner stopped blowing hot air on a 100 degree day! Customer service was great and Kevin not only found the problem fast, but offered us another option to ensure it would not happen again.

From my initial call speaking with Roxanna to having Jorge out, every expectation was exceeded. Top notch customer service and service. Our issue is fixed and we have found our heating and cooling company for life!
Thank you so much Four Seasons! You deserve 10 stars! Best of the best!

Excellent service. Miles went above and beyond to get my unit going so very happy. I would highly recommend this company.

Update-Absolutely highly recommend this contractor! Initially after needing Miles to get my unit up and running, I then started the project of getting quotes to have the unit replaced. Because of the great customer service I received from the service call and their excellent pricing, I decided to go with SG for the replacement. Kyle did an excellent job installing as well as leaving everything neat afterwards! He was very professional (like all SG staff I encountered) and answered my questions and had the office person call me and explain the next steps for registering, etc. I am so very impressed with their level of customer service which is hard to come by these days! Thank you SG Mechanical!!!!

We had a great experience with this company! They arrived quicker than one could have expected with a last minute call with an AC unit that stopped working in triple digit weather. They were highly knowledgeable, professional and efficient. I would highly recommend to family and friends!

Day&Night replaced my heat pump system back in 2014. I have utilized their A/C and plumbing services since then. They are always responsive and professional. I had my system maintenance scheduled today. Tim, the technician, was no different. He was professional and courteous. He took pictures and explained what he did and what needed to be done to keep my system running properly, hopefully for years to come. Thank you Day&Night.

Highly recommend King Mechanical, very professional, fast response, and they were at my house within 30 minutes after I contact them. Thank you again!

Courteous, honest and very knowledgeable.
