Best Heating & Air Conditioning/HVAC in Arizona

I have used Donley for years. I love their maintenance package! It keeps our system running reliably. Super easy scheduling. Juan (my favorite technician) is always on time, super pleasant, does an excellent job of keeping us cool. Thanks for all the years of great service

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.

Put in a call last year with my home warranty company and they sent me someone that made a mess of my ac.  Home warranty called in the help of Martin and he fixed me up the next day.  Called Martin this year, returned my call within the hour. He went over my expectations and text me the next day to check on things to see if I needed help, which I ended up needing. Thank you Martin.

If there are nicer people in AZ-I don't know where they are.  I can't imagine a situation that (even if it was screwed up) they wouldn't make right.  Needed parts for my fridge and they were great.  Is amazon cheaper-yes-but I sure felt better about the experience and was able to help a local business.  Plus they figured a work around on my part...which amazon would probably not do.

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.

I have used this company for a couple of years and I am always so impressed with them. Jason - the owner, takes great pride in treating each customer as if he was treating his own family. Not only is he reliable and trustworthy, but he keeps his prices reasonable.
This morning (Saturday), I woke up to find my AC was not working. I called Jason and by noon it was all fixed and running again. Jason personally came back from some time off to fix my unit himself. He is honest to the core and always recommends what he would do if he was the customer. It's never about selling up. I can't say enough about this company. I know you can never make everyone happy all the time but Jason always tries his best and he has great integrity. I 100% recommend him to anyone needing his services.

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!

They came on time, good communication and performed the repair quickly. I would use them again.

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 called Wolff for an estimate on getting Solar AC units was told that Daikin  unit were better and more economical. Well Mike came out to my home gave me the tour on how I would save money on these unit and no cost for service .I said that is awesome BUT  I do not want to have a finance payment that is going to be bigger than my average electric bill.  So here is what it will cost to replace my units  Daikin HH (2) DZ20VC0481A Variable Speed Heat Pumps 7958771 (2) 4 Ton 20.0 / 12.5
Daikin (2) DV48PVCD14A Variable Speed Air Handlers - - -
Daikin (2) Comfort Net (CTK04) Controllers & Bridge  this totaled 27k   OMG.......    What the H***    Why would I want  a finance payment of $251 per month.  I pay for a full year of electric $2,994.15  if you divide  12 months $249  per month.....  So  they said it would save up to 50% of my bill.  Lets be conservative an say the systems are so good they do 55%  That would mean I would save $137   WOW.....   So that means I have to pay $251 + $112  =  $363 a month.......   I spent more to save......  Do yourself a favor  WOLFF give a estimated price first instead of wasting my time.  Now I asked for SOLAR   WHY????   when using the SUN there is no electric be used and then my ELECTRIC bill is LESS.... WOW what a concept....  Never got that Solar AC estimate.........

As of today still waiting on that SOLAR ESTIMATE.......

11/22/2015 Still nothing from them on installing SOLAR AC

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

I would highly recommend Red Mountain for all of your heating and cooling needs. I recently purchased a new heat pump system from them and am very satisfied with it, all the way from dealing with Tim in sales to Thomas the head engineer. They were prompt and professional in the entire process. Would not hesitate to use their service again

I wouldn't even give them 1 star if I could. My A/C stopped working, I called them out, Rich said it would be $1399.00 for a coil in the attic, blah blah blah.  I was suspicious, called another company, they immediately found the leak on the outside unit and even took video.  The other company fixed it that bill was $800.00  I feel like they were they intentionally ripping me off because I don't understand the heating and cooling jargon.  Then the company calls my cell at least once a week to try and clean/service my unit andI have tried calling them about their fraudulent diagnosis and no-one has returned my calls yet....go figure.  I bought my unit it four years ago and the Orangutan tech suggested that if something else happens with this unit it might be worth looking into getting a new unit. THEN.....he had the nerve to tell me Rheim has had problems with defective coils and they quit carrying Rheim A/C units. If the company knew the units were defective, why was I never called?????    I WILL NEVER EVER USE THIS COMPANY AGAIN, HUGE SCAM ARTISTS.  All I want it my service fee back.
