Best Heating & Air Conditioning/HVAC in United States

Our A/C went out unexpectedly, and we weren't sure where to turn. I went onto Yelp and read over Larson's excellent reviews. And I'm pleased to add my endorsement and recommendation.
I called last night after their business hours and was very pleased to receive a callback from Cheryl within the hour. She was very informative and helpful and set us up with an appointment for this afternoon. This morning I received a call that they could get someone here this morning. Perfect! Caleb showed up shortly, met with us to understand the problem, did a rooftop check of our HVAC, came back down with pictures and a diagnosis, and advised us about costs. He was committed to making sure we understood the problem and our options. He was thoroughly professional and friendly, and did an excellent job of repairing the unit. He also checked out the heating, and reported that everything was good; he also saved me the trouble of changing out the air filters. We signed up for their maintenance program, which will keep us ahead of the curve.
Highly recommend Larson A/C with a very enthusiastic thanks and shoutout to Caleb.

I did a lot of calling around and research for an air conditioning company.  I knew my a/c unit was getting towards the end of its life cycle, and sure enough, last summer it went out.  I already had a quote from American Home and once the a/c unit went out, I called them.  They pulled up my quote and said they could be out the next day.  They arrived on time, and installed my new a/c unit and furnace within the day.  I am only now writing this review, because I wanted to make it through a full AZ summer to see how this a/c unit performs.  It has done wonderful, with absolutely no issues.  Highly recommended.  Excellent customer service.

Mike is fantastic to work with - knowledgeable, thorough and provided quick reasonable service! We were so happy that we're already scheduling routine maintenance! Will call again and certainly buy a new system from when the time comes.  Thanks again and so glad we found you!

Called because our AC was having a hard time keeping cool. I get super stressed over these things but after dealing w Boldt felt much better! Fair, honest, and friendly. I have an old unit that will soon need replacing and I will definitely be calling them when that time I comes. Highly recommend this company!

FANTASTIC!! Our usual A/C was too busy and out was getting hot, I called Jonny and he was over in just over an hour. The problem ended up being the least expensive thing and he didn't try any of the usual up-sell scams the other guys use on you. A very small service fee later and we were off and running again!!

Please allow me to paint a picture for you. It's December, my wife and I have recently welcomed our second daughter into the world and on the morning of our second day home from the hospital our central heating goes out.

Now I know it's Arizona and yeah it doesn't get that cold however this is 2 days after we get home with a baby that had an extended stay in the hospital due to some complications so naturally my wife and I are a bit on edge about this issue.

We have heard rave reviews from everyone who has worked with the Hays family and they were all correct. We reached out and they made space in their busy schedule on the same day, even having their technician Mark work late to resolve our issue and get us back up and running same day!!

To summarize, clean technical staff, fair prices and exceptional service from a locally family owned business!!

Thank you Hays Cooling Heating and Plumbing!!

If there were more stars to give this company would have each one! From the star of contacting them till the end of the service, Arizona Air Experts were excellent! The lady who helped me get an appointment the same day was sweet and has great customer service and great communication, she called every step of the way. Darrin was our technician and he was AWESOME. Very honest, friendly and helpful. He showed us every step of the way of what he was doing and how to help the performance of our AC unit. He was also very patient with us as we had to go through our home warranty for authorization for our reimbursement process. Great company and I will most definitely be using them for our maintenance on our AC and any plumbing service! Thank you so much, your company made our day!

My Evaporative cooler was not working and causing a breaker to trip. I reported the problem to Danette at Cool Zone and made an appointment for repairs to be made.  On 04/25/2019 a technician (unknown name) arrived, and I told him to proceed with the repairs (without asking for a cost estimate).  He completed the work and presented me with an invoice for $826.97 which included the cost of a 3/4, 115V blower motor @ $666. I thought  the cost was extremely high, but paid it, as I had no idea how much the motor should cost. However, I later checked with Lo
we's and Home Depot and found the motors retail for between $85 and $150. I discussed the above with my niece, Kathy, who called Danette and suggested there may have been an error in the billing.  Kathy was told there was no mistake and they would not make any adjustments to the billing. I would not recommend doing business with Cool Zone.  I would be glad to re-think this review if CoolZone would furnish me with a copy of the invoice showing exactly how much they paid for the blower motor.

A++ service. Quick to come out and quick to diagnose and fix. Will have them back next year for tune up. Bill answered my questions without hesitation!

My mom's AC/heater was acting up, blowing smoke all up in her home and Dave from Gladiate Air flew in to the rescue!!! Big thanks to Dave's wife for setting up the same day service!!

When Dave arrived and turned the on the heater, the smoke decided not to rear it's dark cloud, but instead, it stopped working. Dave found the problem & fixed the broken wiring in no time and quoted me with a reasonable price! He was very professional and explained everything to me every step of the way. He's an expert in his field and provided excellent service!

Hopefully my mom won't have much more AC/heating issues, but if she does, I trust Dave and Gladiate Air for all of our AC/heating problems! Thank you Dave, you're a life saver!!!

I've had a maintenance contract with Dukes of Air for three years. They are prompt, polite, and comprehensive. They've done a great job with our HVAC. They never try to sell us stuff we don't need. They have done a great job servicing our HVAC.

Back in April Biltmore Mechanical replaced our A/C and duct work. We are very happy with the customer service and work they provided. The owner David communicated well throughout the project and afterwards. We are still dealing with some issues (low pulsing sound when the AC is on and lights flickering when AC kicks on), and although they are not resolved yet, we are confident that David will resolve them satisfactorily. Highly recommend!

I was having issues with water coming out of the A/C improperly.   After looking at the reviews on Yelp I gave this local Tempe company a shot  and boy,  I am glad I did.  After speaking to Lisa on the phone she had someone had my house first thing in the morning.  

The tech showed up on time and was an overall nice guy.    He diagnosed my problem pretty quickly and was done before I knew it.  

My only charge was the service call(which was very reasonable) for about 45-60 min worth of work.    I highly recommend this local company and will not hesitate to call them again if needed!!

Mike was super responsive and professional. Loved that his system texted me to confirm his appointment, tell me when he was on the way, and when he completed the work.

Had a longstanding service agreement with another company, and on their last visit the blower motor *coincidentally* went out.  They tried to sell me a new A/C unit (for more than $7k).  Thinking that I was getting conned by this other company, I called Alan to get a second opinion on the unit.  He came out promptly, and fixed my unit for $90 in less than an hour.  The service was prompt and on time, and he saved me a fortune.  Thank you Alan for being awesome and honest.

AMAZING COMPANY! We had them come out and do an energy audit for our house to figure out why our APS bills are SO CRAZY high. They spent almost two hours checking our house and our scorching hot attic and presented us with a detailed print out complete with pictures and commentary about the issues with our home. Needless to say, we decided to proceed with their recommendations and the crew of gentlemen that were here today were so great. Proffesional, respectful, kind (humored my 20 month old and repeatedly answered his hello's with a nice response) clean, and friendly. I HIGHLY recommend this company! We will be using them again in the future!

I highly recommend DCM. We had them replace 2 AC units and put in some new ductwork for a home we purchased end of November.  Extremely professional, responsive, knowledgable.  They take pride in the quality of their work and the services they provide, and they do not disappoint.  Their rates are competitive as well (I had gotten quotes from a few other companies).  Joseph was absolutely wonderful to work with.  He is great with communication and following up throughout the entire process with thorough/detailed emails - from initial questions/estimates all the way to after install and setting up warranties for the units.  Shaun was also extremely helpful, detailed and took the time to answer many of our other questions about the home and HVAC.  And lastly, Fidel and his crew were wonderful - very hardworking, efficient and courteous.  My husband and I really appreciated the extra time Fidel spent over going the new systems with us.  Again, I am extremely satisfied with DCM and would highly recommend them.

Mike Cornwell (our ProSkill Services Plumbing Technician) was friendly, knowledgeable, and has high level plumbing skills.  Mike Cornwell has provided other plumbing services previously, and the high bar he set for himself the last time was exceeded on this most recent plumbing service.  I HIGHLY RECOMMEND ProSkill Services and in particular Mike Cornwell  for your plumbing service needs!

The technicians were professional & courteous.  Company had outstanding customer service & reasonable prices.  The response time was great.  They had my ac fixed on the same day.  I highly recommend them!

This place has a great service, and I liked many of the options they offer. I did  not  end up using them but they were the first place to show up with a bid, and only because of a discount available at my prior a/c company was their price slightly higher.
