Best in Phoenix AZ

Have used them two times now and they are great. Competitive pricing and don't try and up sell. Very honest on what they can fix and what you will need in the future.  Would highly recommend.

They were able to come out same day, had great communication, and were honest with what was needed, no sales pitches and no surprise extras. They wee also the only ones I called who didn't ask If the homeowner would be home. Would absolutely recommend!

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.

Great service always.  Chris arrived 20 minutes after my call--amazing.  Solved my problem and was so helpful.  One thing I don't have to worry about!

When my AC went out I called A Quality HVAC Services. I got someone on the line and a technician was at my house within the hour. Mitch was great and got my AC working again quickly. I would definitely recommend this company.

So pleased with this company!! Fair, honest, fast, friendly service. I couldn't have been more pleased. Highly recommend!! Thank you Jimmy!!

Wonderful company! Fixed the problem right away. Stayed on quote. Totally professional! Highly recommend!!!!

Desert Diamond is a very professional and capable company.  Our existing space for the ac/and heat did not lend itself to a more updated system.  Steve was very easy to work with and came out more than once to take measurements in order to give us options for the new system. They completed their work in the timeframe they promised and did a great job.

We highly recommend them for any heating and air conditioning needs.

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.

Beau was efficient and professional! Thumbs up!
We are changing over to their company to have them service us twice a year and check our
Heating & air conditioning to keep in great working order!
Thank you Beau for your professionalism and explanation of the issue with our heating pump!

Excellent service, extremely competent & honest.  Very rare to find all three in one company. We've been using them for years, highly recommended.

When we needed a new A/C, we contacted AC Doctors since we've used in the past and had excellent service.  We got an estimate and scheduled the replacement within a couple days. Luis Urquidez and his crew of 2 arrived exactly when promised and completed the replacement in 4 hours, which really amazed us since the last unit took a day and a half to install with a different company. Luis was super courteous and informative, especially when explaining the new thermostat and remote sensor.  We were especially pleased that they were able to take apart the air handler and reassembled it in the attic, instead of cutting a hole in the ceiling. Our crawl space is tight and the last company that replaced this unit 10 years ago cut a hole and left it for me to do the drywall work to seal it back up.  Luis saved us valuable time and energy by cutting a hole but instead made it through the existing crawl space in a couple pieces. The whole crew did a great job and cleaned up as if they were never here. We will continue to us AC Doctors in the future and would highly recommend them.

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 in the middle of the and had to scramble to find someone to come out that evening. After getting stood up by another company I called up Freddy and he was out at the house at 9:30pm to get it done for us. Got the needed part first thing in the morning and had us back up and running in no time. Freddy made it easy to communicate via text and he was a pleasure to work with. Highly recommend.

Quick service and responsive.
Johnny the technician was very skilled and explained the situation. Definitely would recommend

Honest and dependable company. No oversell, they tell you exactly what you need and they do exactly what they say. Highly recommend.

Scot is the best. Finally found a respectable ac company on the valley. Very prompt and reasonably priced services.  He returns all calls and delivers on his promises. The best service I have received in the last 15 years servicing my properties!!

We've been working with The great people at Howard Air for about 2 years now.  The office staff as well as the technicians could not be more professional and helpful.  We recently had an emergency and they were awesome in responding and resolving our problem as soon as possible.  Highly recommend them.  There service is the best and prices are very reasonable!!!

We used Goettl as a second opinion, the first was a business our warranty company made us use and they were horrible!!! Goettl came out and was very professional and knowledgeable and didn't tell us certain things needed to be replaces that weren't actually broken unlike the other air conditioning company! This was a much better experience and would definitely use them again. As for our warranty company we will be canceling them and I will be giving the other company a very bad yelp rating!!!
