Best Heating & Air Conditioning/HVAC in United States

We have been with this company for over 25 years. After a recent remodel, our A/C unit wasn't pushing enough air to one side of our home. I called on Donley to solve the issue. They modified the work that was done under our original remodeling contractor. When that did not achieve an improvement, they returned and amended their work, and SOLVED the problem. This is just one example from many that causes me to recommend Donley to anyone here in the valley. Thanks to Julian, Kevin, Gary and Jackie for getting it done!

I would absolutely recommend these guys! Fair, honest, and fast! I requested service through my home warranty late in the evening (after business was closed) they were at my house by 1130 am the next day, fixed my Ac in 20 minutes, all covered by my warranty. Chris answered all my questions and also gave me some info on my secondary swamp cooler that I have never used. I'm totally cool now  
Thank you Qual-Tech and thank you One Guard!!

Our A/C went out when we had family visiting from out of town on a sweltering 108 degree day and I panicked! I called Martin and he was able to come to our house right away. He fixed our unit promptly and literally saved the day. He was very professional and friendly and gave us some helpful tips for maintenance throughout the year. I definitely recommend Martin for your A/C needs. We will use him for any of our future service needs.

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.

These were  the most amazing people I have ever seen. Our A/C had been out for 1 week.. but we survived.. I have to tell you that hands down people, this company is the best.. Chase came to our home evaluated the situation and was straight up  honest , he told us  it might take 3 days to get everything needed to replace the unit.. He was here on Tuesday 9/1 and today,9/4.. this morning some of the most hardest working young men came to our home and worked from early morning till after 3 in the afternoon. I wanted to buy them some lunch but they declined very graciously and told me I was one of the nicest customers they had ever met..I sure hope there are more caring customers out there.. Anyway .. Thank you everyone at Valley's Best A/C company for everything.. Lillian

We just moved to Fountain Hills and had the unpleasant surprise of our old heat pump blowing out cold air ( in the heating mode.)  Based on positive feedback I read on Yelp about ASavings Air, I gave Jason (the owners there) a call. Turns out, that was a wise choice.  Jason and Conrad were outstanding throughout the entire process. I own an electrical contractor in MN and know what separates the good from the bad contractor-wise. These guys are rock solid, recommending only what they would install / provide in their own home. My wife and I highly recommend A Savings Air.

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

Bill came out and serviced our 3 year old heat pump. He was very through and explained what he was doing and educated us on a few things since we are from another state and had never owned a heat pump before. I will continue to call Bill for all of our heating and cooling needs. He is honest and truly cares about the quality of his work.

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!

Looking forward to do business with this new Company...will let you know experience.

If you want an estimate from Kings of AC LLC,  the King will tell you in the afternoon. I didn't know that this meant from noon to......  Like I have all day to wait for an estimate. At 5 pm I sent the King a text to cancel appointment.
The King is too busy (good sign), but gave him 2 star because he's a young company....Good luck

If you're thinking about going Solar + Energy Storage, these are your guys! They are nothing short of a reputable, professional, 1st class organization.

I have friends that have worked with them in CA and they are extremely happy post install. Their customer service is great all the way through.

I'm excited to to get my project going in AZ with them!

I have been a customer of Wolff Mechanical for almost 8 years. During that time I have both purchased new Trane systems for two homes as well as contracting for their annual service contracts. Trust worthy professional and customer oriented describe them them to a T. Today they also added responsible to that list. They took responsibility for a mistake that they could have easily denied. The result was a significant amount of rework at their expense. No doubt they have a customer for life.

I highly recommend them! Very happy with the air conditioner. They check the system every few months and very friendly!

Met with Tony Carter from Red Mountain Air Conditioning.  Company is experienced in commercial and custom residential heating and air conditioning installation as well as commercial and residential repair and maintenance.  They pride themselves in doing high quality work at a competitive price.  They also do residential replacement systems.  I met Tony through the Gilbert Chamber where I also have met some customers of Red Mountain.  I hear that they are prompt, courteous, professional and do excellent work.

I'm going to say is BEWARE!
This company left me without air for 13 days and management would not return my phone call.  While I had a great technician come to my home for maintenance, I think that the management team deserves no stars. Even though they just serviced my Trane 2009 unit, management claims they thought my unit was York from 1998-1999!
