Best R O Systems in Phoenix AZ

We have had Joe out twice for two different jobs and he has done an exceptional job both times.

Technician was friendly, Covid safe and very knowledgeable. Since the visit, our air handler, which was working before the visit, has not turned on. We have no air circulation and hence no air conditioning in that zone. Upon calling Hays to have them return to diagnose the issue, the technician came and found the main fan motor was bad and not working. Hays has agreed to replace the motor, found one at the Trane warehouse, and is in the process of replacing that motor. Excellent follow-up and thanks to Hays for taking action to get us cooling again. Highly recommend Hays Cooling, Heating and Plumbing. Good company and good people.

I have used Daniel off and on for 5 years. He his the best most honest plumber. I highly recommend this company!

The technician, Beau Halsey, was excellent: prompt, knowledgeable, and congenial. I will definitely call this company again when I need HVAC work.

Mike was prompt, courteous and professional. He did a thorough inspection of my HVAC system, explained what he was doing and answered all of my questions. He was able to make a few adjustments and tune up my system. I am set for the summer! Thank you Expert HVAC Services, Inc.!

We had a heating issue on our HVAC and we called Goettl to come take a look at it. Goettl showed up the same day to look at the system. Rafael and Jerome were very knowledgeable and found the issue right away. Even though they were quick to find the heating problem, they took the time to ensure that the whole system was functioning properly and that we were able to switch back and forth between heating and cooling. Thank You to Rafael and Jerome for making us feel that we are the most important customers the company has.

James was on time and a true professional. He did great work fast and efficiently.

Called in for an issue we were having with our heater and they came out the same day to fix it.
Tech was knowledgeable and profesional.
Grate company

Did a great job, just like always.

Jeremy was excellent in explaining with pictures and an explanation of mold in the blower. It needed to be removed.

Josh was very professional and hard working.

They were great. Showed up same day when the valley was in the middle of a super hot spell. Inside of 1/2 hr I had cool air back! Only 4 stars because they were a bit pricey at $350 for less than an hour and a $20 capacitor. $180 trip charge that doesn’t apply to repairs is a bit much too. But hey, they were responsive and got cold air going so I’m happy.

Julio and Terry were awesome. Any and all questions I had they were more than happy to answer and then some. It was a total learning experience in knowing how the units work and what does what. I highly recommend them to anyone!

Tech was on time and great to work with.

Called about moving an air duct, they didn't provide that service. They were pleasant on the phone.

Kurtis came out to help us with our AirCon needs today - exceptional service and great advise given - Highly recommend if you need to stay cool CH

Thomas was great! Very through, explained things completely in a way we understood and very considerate!!

I went through six different companies all around AZ with many lead downs until I found this HVAC contractor near me. It was a pleasure to work with them. The service was excellent and they honored the price initially quoted. You won't be disappointed if you choose their quality service. They are trustworthy and reliable.

My home is 20 years old and I have had service every year with Comfort One to keep my units in the best possible shape. Comfort One are honest and it’s nice to see they don’t try to get the most money out of a job. They charge you according to the necessity of the Job and no more. They have kept my units in great shape throughout the years.

They are extremely professional and readily available to help you with your Air/Heating needs. It’s nice to know there are still honest people out there in the Companies they promote. I’ve NEVER had poor service from Comfort One Air Conditioning.

Today I had them install 2 new Thermostats and the gentleman was so kind to not only install my thermostats but he also helped me complete me the download on my iPhone. He set everything up for me and even showed me how to change the temps from my phone when I am out. As far as I’m concerned this company goes above and beyond for AZ residents - ??

Mario and his team are amazing. They have done work for me professionally and personally and I wouldn't trust anyone else with me heating and air conditioning needs!
