I have used Cool Guys AC for my properties in Mesa area for a handful of issues. They have always done an excellent job on repairs as well as new AC installation. Their prices are very fair, and they work promptly. They send pictures of the work and communicate professionally. Mostly, I believe Reno and Lynn are very honest people. These days, that goes a very long way for me. I always feel they provide good advice and recommendations and take costs into consideration when doing so. Five stars for this company. read more

Very happy with their work !!!! On time worked fast left no mess. Blah blah blah there's your 85 characters....

Requested home warranty service on my A/C. Absolutely Zero communication from Cool Guys. Service man spent about 10min. and stated "I do not know how to work on this unit" and then I never heard from anyone !! Warranty company finally cancelled the work order and refunded my money. read more

The tech showed up with a very sour attitude. Tony showed up and said he would only work on one unit. He asked me which one and I said I do not know whichever one has the refrigerant leak. He said well if I check one and I cannot check the other. I said well I do not want to schedule another service call and pay $125 if it is not the one you check out. He then became hostile and told me he did not need to take my sh**t after I told him that he was being rude and disrespectful to the customer. He left and would not listen to me. I had planned to contact my home warranty company and his company to to see how to handle it. He said go ahead and call, I am calling them right now. They had a quick call back time initially and the woman was very nice, but the tech--geez give me some time to figure out how to do this. If zero was an option I would give it since he cancelled my request for service. read more

First off, Reno and Lynn are incredible. My friend referred me to Reno when I was asking about routine maintenance on AC and from the first time I met Reno, I could tell he was an honest person that just cared about doing the job right. He quickly performed a tune up on our existing AC system, showed me pictures of the system so I would have a reference in the future, and explained various topics about air conditioning and ducting. He didn't try to upsell any services, recommended what I thought was a very reasonable tune up schedule, and overall was just fun to talk to. The next time he was over for a tune up, he noticed my capacitor was not in great shape. He showed me what mine looked like from pictures (unit is on the roof) as well as what a new unit would look like before performing the repair itself. Again, his quote was very reasonable and he kept me well aware of what he was doing. Now comes the above and beyond part. Our AC went out this past week...I started freaking out and messaged Reno at 8:30pm at night expecting a response the next day. He responded within 10 minutes and even asked if he needed to come that night. Thankfully it was cool enough he could come out the next morning. He attempted to replace a burnt out switch and when that didn't work he was honest that that meant it was the compressor coil. He gave me the option to replace the compressor or the whole unit (20+ yr old unit) and made it very clear which option he recommended without being pushy at all. We went with his recommendation and after an incredibly reasonable quote (we honestly could not say no), he was able to coordinate the new AC installation in two days. In the meantime he was even gracious enough to let us borrow a portable AC he had laying around. On the day of the new AC installation, everything went smoothly and efficiently with Reno and Lynn working together. They made us feel like family the entire time and were nothing short of incredible, constantly keeping us aware of what was happening. They showed us how they were hooking everything up to make for easy maintenance access, and even took time after the installation to check out and REPAIR some ducting issues we never would've caught ourselves. Turns out we had disconnected portions in the attic that were just wasting cool air... Our AC is now better than ever and we feel completely ready for the hot Arizona summer. When explaining how I feel about Reno and Lynn to our other friends, I don't just recommend them as incredible contractors, but instead refer to them as incredible human beings. I'm very picky with my contractors and have enough mechanical knowledge myself to know when I'm being yanked around. I never had any sense of anything remotely like that with these guys. They're the absolute best and went above and beyond anything I could've ever expected. They managed to make one of the most stressful situations a homeowner can deal with into one of the most enjoyable stress-free experiences I've ever had. Thank you for everything Reno and Lynn. You've got a loyal customer for life. read more

Reno did an annual pre summer air conditioner inspection. 5/15/2025 He went above and beyond what any normal A/C inspection would be. This is the 1st time I have used this company but it won't be the last. Pricing was more than fair in my opinion. Jeff B. read more

Called Reno in an emergency situation for my in-laws. Reno showed up quickly and got everything completed in a short period of time. He is reliable and very professional. The pricing was affordable and I would highly recommend him for anyone needing AC/heating services. Thank you Reno! You will always get my recommendation for anyone looking for services! read more

Great timely service at an affordable price. The issue was resolved the same day.

Reno and Lynn came out same day to give us a quote. We had an original unit from 1993. They were able to come out and replace it the next day. The customer service and communication was great. Also the price was completely reasonable!!! I would give 10 stars if I could. Would definitely recommend. read more

Just came back to our house and our AC unit was not working and Josh and another tech came out and got everything working for us. They were quick, friendly and got everything working. Thank you so much for your service! If you are ever in need, call the Cool Guy! read more

If I could give ten stars I would. Summer in Arizona without aircon is a miserable situation. Joe Boa and Jason were fantastic and the team that arrived punctually at 6 am on the holiday couldn't be faulted. After considering several options and quotes we made a good choice judging by the service we received on the July 4 holiday. Everything they said they would do happened and the quality of the team made a difficult process easy. read more

We needed to purchase a new heating/cooling system. It was a very daunting task. After we contacted Lynn, he was quick to get back with us- gave us straightforward information and was overall fantastic to work with. He was on time, respectful of our property and was willing to answer any and all questions. From initial contact to follow through, everything was great. I would not hesitate to recommend Cool Guys. read more

Best in the business!! Thanks again Lynn and Reno! Cheers, Derrick P. read more

We were given a window time frame from 2pm-6pm and he shows up at 6:45 and acted like I didn't have a reason to be upset. He didn't completely fix the issue so we still have to have an Uv light and safety switch installed. I would not recommend. Even though he was late he never called to say he would be late. My wife and I had to call to make sure he was coming. As a business man you have to be more professional especially as a black business man. read more

I was having problems with my A/C and I called LYN to see if he can come back and fix it, Came to find out the poor guy had surgery and will be out of commission till January. I had another A/C company come out and I found out that the motor that was installed was the wrong one and that's why its was over heating and the the part that was under warranty was never picked up, instead he installed an extra part he had and it was not what the specs required on the A/C label. So the fan motor was over heating and it was shutting off and making us have to leave our home..I was very upset to hear that after I felt I trusted LYN. I dont know why he did that but he is a nice guy and for that I still give him 2 stars but he should have known better...BOOO Cool GUYS.. Come to think of it there was some problems with the fans for my York air conditioner with over heating come to find out so LYN probably didnt know and he was out with surgerey so I couldnt get him back to fix it so I called an old friend instead read more

I was in need of replacing my old AC unit, so I came to yelp to check out company reviews. I'm so glad I chose Cool Guys. Lynn was super helpful, both before and during the installation. He got a quote to me right away. A month later, when I scheduled the service, he was very accommodating with my schedule. He also finished the whole installation in less time than expected (about 2ish hours for a roof-top heat pump). Lynn is also very good at customer service. I asked about a programmable thermostat the day off installation. He didn't have any on him but stopped by a few days later to install one at no extra charge. I really appreciate that level of service. read more

As all yelpers do, when I find a business I love, especially a locally owned one, I want to shout it from the rooftops, or in this case, from my nicely air conditioned home. All thanks to Lynn at Cool Guys A/C. Lynn Smith, the owner of Cool Guys A/C, is awesome. Lynn is professional, friendly, and does the job right the 1st time. I met Lynn when I first moved to the valley and haven't used anyone else for my A/C needs, but I would say that he is the best in town. I urge all yelpers to give Cool Guys a call for your cooling and heating needs. This man knows his stuff. read more

I've used Lynn at Cool Guys when my air conditioning wasn't working and he fixed it way less than any other repair place could ever had for less than the cost. This week my heat wasn't working so my first thought was to call Lynn. He returned my call and set up an appointment. He was here today...arrived 10 minutes before he said he would be here, he checked things out and discovered my fan motor was kaput. He replaced it and another part. He was here for about 1.5 hours and got everything repaired for next to nothing. He is trustworthy, honest and I will only ever call Cool Guys for any of my air conditioning or heating needs. Thanks Lynn!!! read more

My a/c unit was blowing hot air and I knew that I had a problem that needed to be fixed immediately! I read the reviews on Yelp and decided to gives these guys a call. Im so glad I did... Lou was the Tech who diagnosed and fixed the problem with in 2 hours of arriving at my house. He went over all parts and components and made me understand all of my options. Pricing is fair and these guys are in the business for long term! They are trying to build a solid client base using great customer service. These guys are locally owned and operated and I recommend this company to everyone. Great job AC Guys Jeff read more

Lynn is a rock star! If I could give 10 stars I would! We came back in town from a weekend away to find our downstairs at 85 and found him online with rave reviews and decided to give him a call. It was Monday when I called and he said he didn't have an appointment till Wednesday but he was going to be in my area that night and could probably swing by later in the evening if that was okay. Even though it was after dark when he got here he was able to diagnose and fix the problem for us. Neither of us knew anything about A/C but compared to other experiences I felt the charges were more than fair and was very happy to see that there weren't any "after hours" or "emergency" charges tacked on to the bill. :) Needless to say he lived up to and surpassed all of our expectations. I am sure that this is the busiest and most hectic time of the year for anyone in that line of work and Lynn showed up after a verrrrry long day with a smile and was even joking around with us. He is a one man show and you can tell that he cares about his customers and is a straight shooter! Definitely would recommend him to anyone needing repairs in the East Valley (or anywhere in Phoenix) area! Top notch! ______________________ Ben, I do not think that it is fair that you gave a bad/low review based on the fact that he was unavailable to immediately come out. That is like me getting upset because I walked into the best restaurant in town without a reservation on a Saturday night -- it still is the best restaurant in town even if I decided to pass on eating there because I couldn't get a table right away. Shame on you! read more

Seriously if you have an issue with you AC unit, Nest or heater - call them today! You will not regret it - very professional, prompt, knowledgeable and friendly. Ron and his team will take care of you!! read more

Lynn came out today when our furnace flue vent came apart. He didn't charge us a thing and wished us a happy holidays and fixed the issue. He also educated us managing our furnace in the future. While it wasn't serious and didn't require parts, he asked for no compensation and politely declined my offer to pay him anyways. I hope his good will is paid in some other way. He'll absolutely have all of my business when my AC/Heating problems are serious. I hope all of his customers treat him as well as he treats us. Thank you so much! read more

Cool Guys Air Conditioning is more than cool ! I met Lynne Smith when I was moving into my new location. He was there installing a new evaporator for the AC system. Lynne is a very personable guy and his work is clean and neat. We exchanged some cards that day and a few weeks ago a friend of mine needed some help with his AC. I knew just who to call. Lynne was quick to get to my friend and he stayed in contact regarding scheduling. The best part besides the good work is he didn't hold my friend hostage over his need to cool down. His price was fair. If you need some AC work done over the summer, do yourself a favor and call Cool Guys. You won't be sorry! read more

I needed an AC guy to look at a 20+ year old heat pump that blows cold until it gets really hot outside. My parents are living there, therefore I did not want to wait until summer arrives to have it diagnosed. I searched Yelp and found Cool Guys, who was well reviewed and in my neighborhood, and gave him a call. I made an appointment with Lynn for 11 on a Thursday. The first plus for me is that Lynn came across as a genuine guy over the phone; no used car salesman vibe at all. Second, Lynn did not arrive sometime between 9 AM and 3 PM, like most contractor types do, he arrived on time at 11. After arriving Lynn checked the unit, identified that the bearings were shot in the blower motor, and charged me a fair price for the replacement. He came prepared with a replacement in his truck and so everything was taken care of in one visit. The true test of his service won't be known until it is 110 degrees outside, but I have every confidence his fix is the right one. Additionally, while I am pleased with what he did, it's what he didn't do that impressed me. Lynn didn't try to needlessly up-sell. He told my parents, who was at the house at the time, that the unit was old but in good working condition. He suggested running it until one of the major components quite working. Overall, I am very satisfied with the service I received. I foresee the next time I need a unit looked at my first call will be to Cool Guys. -M read more

I have a YMGI mini-split airconditioner that hasn't worked right since we bought it two years ago. I called Lynn after reading all of the reviews on here and thank goodness I did. Lynn scheduled my appointment and got all the model numbers from me so he could do advanced research on the internet on my particular machine. On the day he came to diagnose the problem, he arrived right on time and immediately went to work. Within minutes he found that the coil was leaking and the unit either needed a new coil (which is a very large part) or a completely new unit. With Lynn's assistance I spoke to YMGI tech support and they eventually agreed to send a new coil free of charge even though the unit was out of warranty. Lynn returned the following Saturday to install the part. A few hours later Lynn had the AC working better than the original install. He is honest, he works incredibly hard, and he is very cost efficient. If you need an AC guy, Cool Guys AC should be your only phone call! read more

We have used Cool Guys Air Conditioning and Heating for many years now. We first used them when we needed to replace our A/C unit at our old house. The price was unbeatable. We've also used them several times at our current home to service our A/C unit. Lynn always provides excellent customer service and gives us a fair price. We recommend Cool Guys to all of our friends and family. read more

Lynn deserves more than five stars!! He arrived exactly on time and immediately began to diagnose the problem with the A/C and then the gas heater. In quick time he located the problem with the A/C, replaced a minor part, serviced both units and then went to work on the heater(s), one of which which was not warming the left side of the home. In no time he located a stuck value that controlled the gas flow, adjusted that, serviced both gas units, gave me the bill which I'm sure saved me hundreds of dollars. He is my go to guy now and forever for any AC or heating problem. Well done, Lynn!!! read more

Cool guys have always been punctual and always showed me what was wrong and what they did to fix my ac. In addition cool guys tried to give me the best price possible I'm calling them anytime my ac is out thanks read more

I am giving Lynn and his son a 5 star rating on behalf of my parents. My parents AC unit recently stopped working, which was shocking seeing as how they had paid for a new unit back in 2015. After calling the original business who had put in the new AC unit at that time, they gave my parents the run around. We reached out to a couple other AC companies and Lynn's quote was the most reasonable. Not only was their quote reasonable, but Lynn and his son were friendly, honest, and efficient at their jobs. My dad had contacted them during the week and they were there on a Saturday. We can't say "Thank You" enough. My parents had been without AC for about 2 1/2 weeks, granted they did purchase a water cooler but let's be honest it didn't help much. Once again Lynn, you and your son saved my parents summer. read more

A couple months after Lynn came out I started to have the same issue as before. I tried calling Lynn to get the issue resolved but he was down due to back surgery. I don't penalize Lynn for getting surgery and being out of work. I do think he could have had recommendations lined up for his repeat customers who called while he was down. Instead, I had to track down another company and have them come and do the work. So far I haven't had any issues with the work that was performed by a different company. read more

Lynn is the most honest person I ever met among all the big/small companies I have had over the years that came to my house to fix/repair things. We had a big chain company over to do a AC tune up. In the end the guy told me we needed to pay over $1800+tax to clean/replace/fix things here and there. He showed me a picture on his phone of the dirt coil up in the attic. I didn't do it for sure (which I am so glad right now). I did more research on yelp ,BBB and ROC (btw, the information on BBB is not very reliable at all. I have had quite a few bad experiences with the companies that bbb enlisted as A or A+, I will not use BBB as a referral any more) and found Lynn. from all the 5 star reviews, I had a good feeling. I called him and made an appoitment at 8am. He showed up at 8:03 and even apologized for being late. I would not call that late. :-) He went to the attic to check and told me that the coils were not dirty at all. (The guy from the other company must have taken that dirty coil picture somewhere else and kept it in his phone to show to people. what a shame!). Lynn also told me there was no need to replace the fan motor and add more freon. He cleaned the outside coils for free and cleared the drain line. In the end I paid 2 hour labor to get my AC fixed. what a big difference between $1800+tax and $144. I will highly recommend Lynn to my friends and any people out there with AC issues. It's so hard to find an honest person/company to tell you the truth . I will have him over every year to have my AC tune up done. Hope my review will help someone not being ripped off by those big companies out there. read more

The Nest thermostat in my home suddenly stopped working. The display was black and when I opened up the app on my phone the status was "not enough power for wi-fi." After some investigation is was determined that something was wrong with the unit. I called Lynn and explained what happened, he came out the same day to properly diagnose the problem. Turns out the board was bad and needed to be replaced. The new piece was a special order item and Lynn was able to find it quickly and get the unit back up in running within days. Lynn was on time, professional and provided quick service. Thank you! read more

Lynne saved us today; our AC unit froze up and needed a freon recharge amid the height of 115 degree summer day heat. He was here within a half hour--guess I should be glad that Yelp was really the only place I could find him and that I took a chance on one review. I had been on hold at a couple larger companies who then told me they were all booked for the weekend and couldn't dispatch anyone. Of course then I remembered there is a reason I try to support small business. CGAC is a one man operation and the price and service were professional and excellent. It was pretty memorable when Lynne jokingly responded to my comment that "I'd think they would have more than one AC unit for a two level house" with a "there you go thinking again." My best to him and his business. We'll be using him again and passing his info along. read more

We have owned our home for many years and have always used Company "X" for our A/C and heating needs. Over the past few years, Company X never seemed to fix our problems on the first visit, always required a "call-back" visit, sent a different guy every time (even on call-backs), and was charging me exhorbitant prices. A recent visit (and another call-back) with Company X (in a story too long and boring), and I had had enough. They were telling me ridiculous information, and the price for a part (for something they should have fixed on the FIRST visit) was going to be $350.00 plus labor. (I had already spent over $500.00 a month earlier.) I decided to get a second opinion. Because of the YELP reviews, I contacted Lynn at Cool Guys. Lynn did confirm the problem; however, he quoted me $80.00 for the part (a BIG difference) plus labor. In addition, he solved our problem on the first visit. Lynn was able to get out to our house in RECORD time. He got right to work (no chit-chat while charging for his time). He was professional, honest, fixed our problem on the first visit, and his prices were VERY reasonable. I was very impressed. Lynn at Cool Guys is now my new A/C guy! read more

Lynn was flexible, friendly, trustworthy and knowledgeable. He didn't replace any unneeded parts. I would highly recommend him to anyone!

Called and left a message with problem and phone number - heater in one of my Phoenix houses was not working. Also called several times without leaving a message. He must have more business than he can handle because he was completely unresponsive. read more

Found this company on Yelp and gave them a shot based on their rating. I was impressed. Not only were the able to come quickly, they found the problem and made the repair just as fast. Pricing was very fair and I will totally use them again. read more

Lynn, with Cool Guys AC, is great. My appointment was at 2:30 and he showed up right on time. He did an inspection on my AC and made sure it runs smoothly in the hot AZ summers. We have used him in the past and he is honest and doesn't try to fix things that aren't broken. If something is wrong with your AC, or if you just want to make sure it is running good for the long summers, call Lynn. read more

Just like many others, I don't know much about AC, and I had a problem needed someone reliable, so I jumped on Yelp and picked the best of the best. Well, I called Lynn, he appears to be very nice on the phone. But he was all booked up very busy, nothing is available for the next 5 days. :( Its 110 outside, and I need someone here within a day or two at most, not 5 days later. So I have to call other, and got someone else here within an hour and I was happy. read more

Absolutely the best AC service I have ever had. Joe was honest, courteous, took the time to explain everything that was going on with my unit and did an amazing job . I have had him fix another family members leak and he did a fantastic job giving us many options so we could understand the situation and spend the amount of money that made most economical sense to us. I have dealt with many different companies in the past due to a bad unit that was installed in my home 11 years ago. Every time I was either waiting days for the technician to come and or they would come and over change me for parts and labor. This will not be the case with Joe. If you need AC service, call cool guys AC. read more
