Best Heating & Air Conditioning/HVAC in United States

I am only giving 1 star because 0 stars is not an option the service was so horrible.  

We have used Donley to service plumbing emergencies at our rentals for about 10 years.  Though prices have gone up recently ($650 to scope a main line), we didn't have any customer service issues until today.  Unfortunately, it was such extreme rudeness and lack customer service, we will never do business with Donley Plumbing again.  

I called due to a plumbing emergency at a rental. After having to make 2 calls to the on-call dispatcher, someone called me back trying to push the service to next week.  I explained again, it was an emergency and couldn't wait. I was told it would cost more, but the tech could be out in an hour or two to service.  (I understand off hours service costs more.  I can't control when things break.)  2 hours later, an extremely rude technician, Walter, called and informed me his tools were broken and he could come out and look at it, but he wouldn't  service the emergency. This would incur the off hours service fee, but he wasn't going to fix the issue.  In further conversation, he ultimately just didn't want to take the call because the drive was too far.  We told him we were going inform the company of his poor service.  He said he was the supervisor and it didn't matter.  

We will not do business with Donley in the future.  If you have a plumbing emergency, I would recommend calling a company with technicians that want to work.  Donley wasted over 3 hours of our time today, delaying the ability to triage the plumbing emergency because they were too lazy to come look at the issue.  I could have had the issue resolved today if they were just honest and said they didn't want my business when I initially called.  

I can understand if Donley couldn't fit in the emergency service, just say so on the initial call.  It's unreasonable to  waste 3 hours in an emergency situation, then say you don't want to service the call.  Since Walter is the supervisor and there's no escalation option, posting to save others the hassle.

I've got to give 5 stars to Qual-tech as they were so responsive to my needs during a recent air conditioning outtage. While I had to leave a message both times I called, they returned my call quickly.
Of course as things happen on a Friday I went the full weekend without air. The part they needed wasn't available but on Monday morning they quickly came and replaced the board for our air conditioner. The tech was friendly, thorough and efficient. Air is back working again and I highly recommend their service. Trustworthy, and does not overcharge or make up problems to earn additional money.

I will not let anyone else service my heating and a/c.  The first time I met Martin, he fixed a problem that everyone else ignored.  He recently came out and did a tune up before the summer heat hits and recommended some additional work to save me money down the road.  He is professional, tells you exactly what he is going to do, what it will cost and how much time it will take.   He is a busy guy in the summer so don't get upset with him if he can't rush right over or turns down the job, but if you can wait for him it will be worth it.

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.

My review is overdue.

Air conditioning not working properly on 8/18/20 and was referred to this company. Arrived same day and John began troubleshooting the problem. I'm in a complex and multiple units on the roof are not well identified. But he figured it out, took pictures and properly marked the unit. Replaced condenser fan motor and solved the problem. John was well trained and did a very good explaining the issue.

Had them back to replace old thermostat with a new Nest. Valley Best did a great job for me and system has worked great in these crazy temperatures. Thank you.

For a small charter school, we have to watch every dime.  Jason delivered on every promise, on time, affordable, and excellent service. Very dependable. I highly recommend.

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!

Kings of AC were responsive, and came out the exact day that I needed them at our Airbnb. They fix the problem for a very reasonable rate and we are extremely grateful for their service. I will use them again for sure.

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 am an East Valley realtor and only use Wolff Mechanical AC, Heat & Solar because I can trust them to do the work quickly and honestly.  When an inspector states that the a/c needs servicing, Wolff Mechanical puts this time sensitive repair on their top priority list!  I cannot say enough great things about this company!  It is locally owned and operated and the customer service is superior!  They are an award winning company for a reason!  L Lane, Phoenix, AZ

Shawn arrived at our home an hour before scheduled *he called to let us know he was 30 minutes away * he diagnosed our problem with confidence and went straight to work. He was professional, honest and made us confident in knowing we chose the right company. Our A/C is working wonderfully! Highly recommended. Thanks again, Shawn!

We researched many AC companies in the Phoenix area for a complete new HVAC system and Tim Friederich of Red Mountain Air Conditioning was always quick to respond to our many calls and questions. He clearly explained the pro's and con's of the many systems on the market and on his advice we decided on the Trane XR17. We scheduled the installation date which was promptly installed in one day. Tim was extremely professional and recommended we balance the system with some extra ductwork to ensure maximum efficiency. Tim inspected the installation and instructed us on the Thermostat settings. The installation work was all completed in a timely fashion and Tim's follow up was impressive. I would highly recommend this AC company and Tim Friederich. Thank you for a cool summer season.

Well I can't believe all the negative comments but my brother and law used them for his new ac , we did, then my son fid. No problems. Love our new Ac! Very professional people!
