This company has *exceeded our expectations on every level. We were in desperate need as our Trane heater was failing miserably during an extreme period of hard freeze. I would like to first list the amazing bullet points for this company, before I acknowledge individuals. ACS provided us with service that was: Timely Informed Conscientious Thorough Clean Responsible Well rendered Knowledgeable *Ryan Foreman, (who was an installer and is now in sales), was sent out immediately to assess our circumstances. He was thorough in his assessment, very considerate of our circumstances, and extremely professional and pleasant. We had a bid by that afternoon that was intelligently rendered and easily understood. We were awaiting other bids but realized quickly that ACS was the company we trusted to do this installation for us ( based upon the service provided so far, and also by reading reviews online. Very impressive.) As we were in desperate need of a new unit ,*Erica ( in office) arranged for us to have : *Dustin Hardin arrive very early the next working day as our installer. He is third generation Hvac and very competent, mature, focused, and pleasant. And incredibly professional. *Very impressive!!! *Dan Walters was the individual who measured for our new unit the afternoon prior, and he was the second half of the team on installation day. Friendly, kind, hard working, and understanding of our circumstances, he did his best to assure us that we were in good hands! This team takes great pride in their work, and it is obvious from start to finish. They even kept an amazingly clean work space which is, frankly, rather rare nowadays. We consider ourselves blessed to have ACS help us through this trying time. We will tell everyone, as we already have, about the quality of work and level of professionalism from this entire company. A big shout out to ACS and the team of Ryan F., Dustin H., and Dan W. for making our home ever so much better than it has been in years. read more

The installation team, consisting of William and Eddie, arrived at 6:20 a.m., as promised. They worked straight thorough until 7:20 p.m. installing my new 5 ton Daikin A/C system. Both men were very professional, starting to work immediately upon arrival. They did not rush the job, instead being very careful to do everything properly and to the highest standard. They were very courteous and easy to talk to. They answered all my questions (I only bothered them a lot!) and, when asked, explained what they were doing and the purpose. They were very careful and neat, and cleaned up the work areas perfectly when they finished, hauling away all debris and trash. This is the fourth A/C system I've had installed in my homes, the first by ACS. My entire experience with ACS has been by far the best, easiest, least stressful and most satisfying of all. Both William and Eddie, and Kevin and Ryan, were all excellent and responsive, and all were professional and a pleasure to work with. I would recommend ACS and these fellows to anyone considering purchasing a new A/C system. I would give them 10 stars, but five is the maximum! Ian F, a very satisfied SaddleBrooke homeowner. read more

We highly, highly recommend ACS for AC service and installations. We have been in Marana for over a year and purchased a wonderful, relatively new (4 years old) home but with a faulty designed AC system. The builder touted the home as a two zone system but installed a one zone system that has failed at least twice and has never cooled the house to our comfort level. Having tried several AC companies, we found ACS when we came home to a 95 degree interior temp on a Sunday. Called them for emergency after-hours service and they fixed the problem. Recently decided to upgrade our overall system and again called ACS to suggest solutions and provide a bid. They recommended a Daikin multi-split system to create a true two zone system using our existing duct work. Very, very satisfied with their solution and cannot recommend them more highly. read more

Rooftop unit went out in late December. Too old to repair so I got 4 bids. ACS wasn't lowest but was very competitive for a good unit. Ryan gave complete explanation of process, equipment and ACS responsibilities. Scheduled instillation right away. We were away when the installers finished so they couldn't get in the house to check the work. There was a problem so next morning I called bright and early and got a callback a few minutes later. Dan was scheduled to come out. He arrived that morning, on time, and with Noe helping had the problem corrected, unit up and running by noon. Ryan followed up a few days later. Service was great, don't know how it could be better. Hats off to Ryan and Dan. This is the first time I've ever written one of these reviews and am doing it because ACS has shown their stripes...first class all the way. read more

When you are spending nearly $10,000 on a new gas pack, it is hard to be "overjoyed" at the prospect. However, we were overjoyed with the service, thoroughness, quality of workmanship, courtesy and professionalism of the employees. We had gotten a bid from another reputable HVAC company with whom we had dealt for years but decided to seek a second bid. Not only was the price slightly better but the warranty was incredible for the very same unit. Every detail of the unit, its installation, its functioning including the thermostat, was explained. When they finished and left, there were no traces of their having been there except for wonderfully quiet warmth throughout the house. It was wonderful to experience 5-star service. read more

Our AC was limping along earlier this month, and finally had to be put in a wheel chair to cool our home to 78, at night. ACS returned our call within 15 minutes and scheduled an appointment for the next morning, SUNDAY. Jake came in got it running cooler, longer, ordered some parts, saved us some $ with a maintenance agreement and as of Thursday has our AC running almost better than new. He and his company are terrific to work with, and do what they promise, WHEN they promise it. I am so pleased with this company, and highly recommend them for any AC needs. Jake was our technician (wizard) and knew exactly what the problem was within a very short time. Such a polite and knowledgeable young man.... Thank you read more

My AC unit went out on me today. Always on a weekend!! I decided to call ACS when I read the reviews on yelp. Saturday afternoon, my information was taken immediately and a technician followed up with me within the hour. I was 2nd on the list and clear across the valley and he still make it to me when he said he would, just a few hours later. Wow, within 10 minutes he had the issue diagnosed, within 20, fixed! He explained what he was doing and did no try to sell me more than I needed and totally above board. That was refreshing! Thank you Jake, you made my year!! I can't say enough about this company. I will definitely use them for all my needs in the future. read more

Jake,the technician who came to do the final inspection and testing of my new air conditioning unit was very thorough and explained everything to me.He was professional and appeared to be very knowledgeable.When he left,however,I discovered that 3 of my ceiling fans were not working any longer. I called the ACS office and he was scheduled to return the next afternoon to find the problem and fix it, There was no notation on record of the problem encountered with the fans on initial installation of the new A/C unit so he didn't know about it until I told him.He was able to fix the problem quickly and easily once he knew.I'm very happy with the new A/C. read more

Middle of summer, the AC started to feel luke cool and waning. We scheduled a maintenance with ACS. The tech showed me the damage and explained it in terms I could understand. We were able to get a quote for a new unit that same day. The estimator heard my concerns and gave me exactly what I asked for with the crew showing up a few days later to install. I like the way this company operates but the real upside is the people that represent the company. The original tech, the estimator, the crew. They answered all my stupid questions and were very personable. I told each of them they were welcome to work at my home anytime...and I meant it. read more

We signed up for a one year maintenance program offer by ACS. This includes a spring and fall visit by a technician to check out the system. Firstly let me say that the office staff was polite, professional and informative. They scheduled our visit and keept us informed as to when the tech would be there. The technician (Mark) arrived and was also very professional and explained everything he was doing. He thoroughly went over our 10 year old system and gave us a thumbs up . Although no actual repairs were necessary on this occasion, I feel confident that this company will take good care of us when we do eventually need them. read more

I have been a customer with ACS since 2010. They sold and installed my Trane heating and air conditioning unit and have maintained it ever since. As indicated by my "5 stars", they are the best. They are true to their word in many ways. Their technicians are well trained and those that don't seem to meet their standards don't work their long. They have great staff, great service, and have kept my unit running well and have done as well for my friends. While they are not the cheapest, they are of the highest quality, so give them a try! read more

As usual Dustin and his crew provided outstanding service. Response time was amazing and Travis was very professional and proficient. Travis demonstrated high knowledge of his trade and diagnosed the problem within minutes. He was very detailed in his explanation of the issue and provided me with options to correct the issue. He also took the time to perform a functions check on other items within the unit to ensure proper operation. Very pleased with ACS and wouldn't hesitate to use their services again in the future. Thank you. read more

Matthew Acararese and the whole ACS crew were the best!!! This is the most impressive company and crew that I have EVER had in my house for an installation. Strong work ethic, attention to detail, and cleanliness. The crew came to our house at 7am (as promised) and worked the entire day clear until past 6pm. Each of crew was respectful and polite, checking with us constantly to make sure they were doing things exactly as we wanted. I strongly recommend ACS!! read more

I called ACS to conduct an annual maintenance on my HVAC unit. The service technician, Manny, showed up on time and was very polite and very courteous. He did not try to sell me anything I didn't need. He let me know the condition of my unit and was very encouraging. I appreciate the honesty and integrity that I experience every time I call ACS. Thank you! Definitely five stars!! read more

Very professional and reliable. Their service is amazing! I love that I receive a text reminder with a picture and review of the tech that's scheduled to arrive for your appointment. We ended up using them to replace our system and were very pleased. Pricing was competitive, and after the install they sent someone out to make sure everything was completed to our satisfaction. read more

After much research, I chose ACS to install a new package a/c and heating unit on my roof -- and I'm glad I did. Everyone involved with the project was knowledgeable and professional; the install was flawless, the price was competitive, and the system is quiet and effective. Can't recommend them highly enough! read more

I needed a check done since my AC was blowing hot. I knew one probable cause but wanted their opinion. Their tech Brian Jujan was very pleasant and showed me the other cause. We discussed self fixes and he was out the door. Always pleased with ACS. From install to follow up. read more

I asked Dominick K. if he would give me an estimate to replace my furnace motor. He was prompt, professional and knowledgeable. Unlike other companies, he made the experience personalized and felt like I was getting honest answers. I will use in the future. Thank you ACS! read more
