Best in Phoenix AZ

I had a Donley Service technician come out last week to look at my A/C unit as we were having air circulation problems in the house.  Unfortunately I had diagnosed the issue correctly, so it was left unresolved.  The true problem showed its head this week.  Donley Service Center sent a technician out at no charge and this time around we found the problem.  Matt T. was outstanding, quickly found the problem, showed me what was happening, and fixed it!  Things are working well.  Great service from this company.

Pretty typical AC business. The technician arrived on time. Didn't say much .. serviced the AC machine outside and then charged me for the work. Seemed to be more expensive than what I'm used to paying, but this was the first place to answer their phone after I called 4 other places so I went with them.

After having a couple lower quality AC companies (via my home warranty) try and fix my AC unit, Grand Canyon came out and found errors that other companies have made. Martin is a great technician and I highly recommend him and Grand Canyon.

Our dryer died and all diagnostics showed it needed a new control board. We found some on Amazon but delivery times were way out. I found Kevin's on Yelp and called. They knew exactly what we needed, they were able to order it in for next day and their price was much better than Amazon. I picked it up the next day and a few hours later returned the code for a refund. They were very accommodating and well priced. I highly recommend.

Hands down the only company I will ever deal with for anything HVAC related. Valley's Best has replaced our AC unit in our old place and repaired our unit at our new house. On every encounter with them they have been professional, honest, respectful and have a great sense of urgency. The owner Chase is honest and knowledgeable. Marlene the office manager is incredible she truly goes above and beyond and is such a compassionate individual. The techs who came to our were super knowledgeable and quick to resolve the issues. Highly recommended this company for your heating and cooling needs.

Had a leak to the heating/ac unit  where my brother lived. It's a HOA governed development. Thank God the management company was on the grounds that day, they turned the water off to the unit.  
The HOA referred Jasons company to me.  Nice guy named Mel showed up...no emergency happening now...because the water was already turned off, but $155.00 later and a estimate of 5,300.00 later, proved to be a joke.  2 estimates later the next weeks, Jason was clearly trying to take advantage of a situation, a gentlemen would not have.
Not going to work with the warranty company period..and no time to educate me on details.  
Do your homework...call a second opinion.

We got to know Sam before he started his own business.   We will follow him WHEREVER he is!  EXCEPTIONAL!

Thank you for coming out on very short notice and helping me with my AC unit. Y'all are honest and I appreciate that you shoes me what was wrong with my unit. You're very professional and showed genuine concern for my family.

I have been using this family owned company for my home and business for years. I have had first class service from them. Jason who is the son has taken over for his father who is in remission from cancer. He also is a very kind and caring man who taught his son well. I have called Jason on crazy hours and yes even Saturday and Sunday and they always fit me in. I have sent him to my parents on a Sunday he came out and fixed the problem. He is  very reliable and very kind and caring. Jason I cant THANK YOU enough! If I had known about them being on Yelp I would Have shared this sooner!

These guys are a great team! They did a full installation of my new air conditioner in great time and at a great price. I highly recommend this company for your air conditioning needs. They even registered my warranty and took and disposed all the trash and old unit! They are brothers and work very well together. There philosophy is to do it right the first time. Well, they did it right. I had no issues whatsoever. Thank you so much!

Working with Semper Solaris was a pleasure. Dennis walked us through all our options for the system. He made everything very understandable and let us know what to expect every step of the way. The rest of the Semper Solaris team also communicated very well and kept us updated on the project. They handled all the paperwork and made the entire process very simple.Thank you Dennis and the Semper Solaris team!

Best AZ Company in the Valley,   Proffessional,  just the best!  

Quoted fast,  put 0-24 % in place within the hour,  Problem solved within 3 hours,  better than any other company in the valley.

We called Howard Air today because our A/C & Heater socket went Kablooie. They said they would be here around 3 PM, but they over delivered. Theron our tech called a little before 11:30 am. He arrived before 12 pm. He figured out the problem and repaired our blown out socket and wired it back up in a jiffy. He made sure everything worked, meaning the heat came on, and the air conditioning worked and cooled as well. We need more people like Theron in this business. He deserves great accolades and I will ask for him again, when we need help. Thank you Howard Air, for making sure we keep our cool! Sorry, for the dad joke.  Because we need heat as well and that works too.

I had 2 other companies give me bids for a new unit before calling Red Mountain.  They each could not schedule an install for 7 to 10 days out.  Red Mountain sent Tony out to my house with an exact time for appointment and Tony was on time.  He obviously has a lot of commercial and residential experience.  Helped me figure out my AC requirements.  Worked with me on pricing and was able to schedule install 3 days out.  Install crew was exactly on time.  Got the unit installed efficiently and left my property cleaned up beautifully.  Tony came back to my house 5 days later to make sure the equipment was working properly I was happy and to review my warranty information.  I will definitely be recommending Red Mountain to my friends and family!!

Reviews are true! We had an issue and called to schedule an appt. only to find out that the appt was never scheduled. After a lot of frustration, we finally got another appt between 2-5PM, at 4:45 PM, we receive a call that they need to reschedule. I lost it . We purchased our unit through home depot and American Home Was the company that used to service and was wonderful, orangutan now services and we are so disappointed.
