I called them in the a.m. and they were out in the afternoon. They were professional, efficient and very helpful. We were presented with multiple options and within a few hours we were up and running again. Thank you so much Mountainside Air!

My experience with them was great. I had an issue with my unit on Saturday when all other places were closed but was able to reach them. Raul was my service rep. He was amazing and allowed me to stand over his shoulder as he worked and explained everything he was doing along the way. Overall a great experience!

We were very pleased with our experience with Mountainside Air. They were recommended by our neighbour friends. Their service, professionalism and follow up is exemplary. Tom and Steve scheduled initial visit for a quote and provided us with several options for AC and furnace systems. We had 3 quotes and were really impressed with the warranty for follow up servicing of AC/Furnace units and the pricing of units. Their pricing and service warranty is much better than the 2 larger companies we also had quotes from. Their team arrived on time and worked so hard to get project completed. We feel Mountainside Air is very trustworthy and knowledgeable. We would highly recommend them and very happy with their service and our new AC and furnace units.Thank you to the team at Mountainside Air.Leah & Rene

I really like Mountainside Air. They were willing to write back and forth with me because I am deaf. They explained everything clearly. They had a lot of patience with me and listened well. They installed a new HVAC system (air handle, unit, thermostats, and grill ventilation) and did a high-quality job. Good prices than most of their competitors. 100% satisfied. Recommend Mountainside Air!

*Updating review after speaking with the owner Tom who addressed and resolved my concerns appropriately.AVOID at all costs. Replaced AC motor for $1,121 on Wednesday 10/4. Three hours later AC was randomly turning off. They came out again and said it was a separate wiring issue. 36 hours later AC is blowing hot air. Find it really hard to believe that 3 separate things broke as a coincidence within that timeframe. Seems logical that the wiring was jostled during the multiple hours fixing problem #1, especially given the fact that the tech commented that it took longer than expected. That's really reassuring. Save yourself the headache and additional expenses and book a better HVAC company.

We experienced an A/C failure the night before we were supposed to leave for vacation. Unfortunately, my 80 year old mother was staying behind so we couldn’t leave until someone came to look at our unit. After calling a few places, we found Mountainside Air and they scheduled a same day appointment for the afternoon. The tech, Josh, was on time, very helpful and while he wasn’t able to fix our 25 year old A/C, he did provide a lot of helpful information to get it fixed or replaced. I will definitely call Mountainside Air again when we have a problem.

Mountainside was fantastic to work with. We called on a Sunday morning, when it was 95F inside and they responded immediately. Due to the extreme heat wave they had to schedule us out one day, but they brought several portable AC units to keep the house livable. The owner, Tom was the one who took the call (again, on a Sunday!) and gave us an immediate, firm quote for both a repair and a new system. Everyone else we spoke to, wanted at least 24 hours to send us an estimate, which, when your home is dangerously hot, those hours are critical.Mountainside's quote was so amazing, it was actually $500 cheaper for us to put in a NEW unit, than it would have been for a REPAIR with any of the 4 other, top-rated companies on Yelp.We now have a new system that has a 10 year warranty, that is working beautifully, keeping our family cool. We also have a phenomenal go-to for our HVAC needs for ourselves, friends and family.

I’ve worked with other AC companies in the past and always felt like they always wanted to up-charge me for repairs that weren’t even needed. Not with Mountainside. I really appreciate their honesty and my AC is working just fine now because of them.

I highly recommend Mountainside Air! They are responsive, professional, and really know what they’re doing. I had an expensive repair and they were kind and went out of their way to complete the work on the same day. I will definitely call them the next time I have an HVAC issue!

Tom is my new hero! I was recently in a very stressful situation. It was the peak of summer in Phoenix, and I found myself with no air. I have a saltwater fish tank and the animals cannot handle heat. The temperature in my house was rising fast and I feared for my watery friends. A different “emergency” air conditioning company had told me that they were coming for eight straight hours all throughout the night. They strung me along and never came. When I called Mountainside Air out of sheer desperation at 6:30am, Tom immediately answered the phone. Tom was at my house at warp speed and got my air back. He saved my beloved pets. Tom exceeded all expectations. In addition to being extremely accommodating, Tom shared pictures of my a/c issues and was very professional. He took time to explain things very well. Thank you Tom, for saving the day!

Tom came out on time, was very professional, knew his trade well, kept me informed every step of the way, invoiced me correctly and I am very impressed with all aspects of the AC repair that was under the other bids we received. Fantastic service!

The HVAC Tech was very helpful and above all honest. We had been told in the past, by other air companies that we need a new unit all together ($32,000 for both units) or told the system pressure is high it can explode (seriously was told this by a large AC competitor, 😳 that has done most of my plumbing tankless and soft water work), so moved on to give Mountainside a shot, and the Tech showed me the digital readings while testing the equipment, showed me what the readings should be at as documented on the equipment, then pulled out the new part (Capacitor), tested it and showed me it's digital readings that they should be at, installed it, fixed and quieted the system. And to top it off, when I was paying for the service, my license shows I'm a Military Veteran, he gave me 10% off, NO OTHER Air Company has done this. I highly recommend this company for honesty above all!

What an amazing experience! This will be my go to AC team without hesitation. Josh and his assistant came out to the house took time to assess the situation, and explain what was going on. They could have easily fixed what I was initially told by another AC company but Mountainside Air has integrity and didn’t do that. They provide high quality service, have techs that are problem solvers and who actually care. I can’t thank you enough for the service you provided. Thank you!

What a great experience! We know it is never fun in the summertime to call an AC company. This literally has changed my mind in many different ways. I really was expecting the technician Joshua to climb down off the roof and give me the most expensive I work on commission type of news, that would have only been beneficial for him and not me. I completely stereotyped the wrong company!Joshua showed up at my Locksmith store in Sun City with a smile on his face, and 108° weather. He came in and introduced himself, and I described the issue/issues I was having. He was a great listener, and ultimately listened to what I said. With that information off to the roof he went. 30 minutes later he came down with some pretty unexpected news. Again I figured it’s time for that commission check news. Joshua tells me. “ your AC on the roof is working great and I do not see any issues.”. Really? What AC company tells you that in the middle of the summer in this day and age.?It took about 15 minutes to explain all the numbers and readings that he took from the unit which I was more than happy to listen to. He is extremely knowledgeable about the systems for sure, because he explained in great detail what the AC unit does in the summer. I loved it. he did mention if we ever needed an AC company at the shop or at the house to give them a call and they would be more than happy to come running. And they have to say based on Joshua’s non-car salesman approach to the situation mountainside air has now made a new customer.All I can say is what an honest dude! Thank you Joshua for taking the time in this weather to jump on our roof to make sure we are going to make it through the summer. We will call again.Bill from Kwikpick Lock and Safe.

I purchased a 20 year old home with a failing A/C system. I had my faulty ductwork corrected, 2 new Units installed - 2 new thermostats installed too! House is 2200 sq feet. Tom and his team did a wonderful job. They had great reviews on Nextdoor and this is why I reached out to them for my 3rd quote and I’m so happy I did!! (Feb 2022) They just came out for a A/C tune up and they once again provided AAA service! Thanks everyone at Mountainside Air! Also, love that it supports Veterans and family owned and operated. Thank you all for your service! 💪🏻

My ac unit was performing poorly last Thursday . Wouldn't cool my house below 87 in the afternoon. I called Mountainside Air. They scheduled me for Friday afternoon between 12-4pm. The tech was here at 1230 pm. He did a thorough check and determined the problem. Had my unit up and running properly a few hours later. And it has been working fantastically all weekend even with the almost record high temperatures. If you need ac work of any kind this company is worth using. No high pressure sales tactics just fast fair service. From now on Mountainside Air is my go to company for all my ac needs. I rate the 5 stars.

Excellent company and outstanding crew. Had a new AC installed under 24 hours after calling them. And they were all highly informative and professional.First company I called took 2 days to come out and then never called to schedule a time to do the work or returned my calls to get a quote together.

I feel like Mountainside Air has saved me twice now, and both times were same day which is imperative in Phoenix, AZ. They gave clear options, explained the process, and I love the website that let's me see how close they are to arriving.First, they saved my home's A/C and it's been running well ever since. About a month later they had to make a repair at my townhome rental. Another quick fix *on a Sunday* and my renters shared they did not feel inconvenienced.I don't want to have to use Mountainside Air's services that regularly, but I'm glad I know a dependable repair service when needed.

I’m very happy with my experience with Mountainside Air. My AC stopped blowing cold air and even though I didn’t call until 5pm they had someone to my house by 6:30 pm. Tom was very professional and thorough, taking the time to explain everything he was doing and what he saw including showing me pictures he took of the unit and the things he noticed. I will definitely be using them for any other AC needs in the future.

From the initial visit to the full system replacement, the teams were professional and great to work with it. Steve and his team were at our house and ready for a full system install one day after our initial visit. The team did an amazing job and the entire process was seamless and easy. I highly recommend Mountain Air for any of your heating and cooling needs!

We finally had to have our 20 year old A/C unit replaced. When I reached out to Mountainside Air they were responsive and I could tell they were concerned with getting us what we needed. Tom made the scheduling easy through the entire process and the communication about appointments and the quote were thorough. The team of technicians worked quickly to get the A/C installed and the ductwork updated. Everyone was thoughtful and courteous in my home. The new unit is so quiet and my house is much more comfortable. I couldn’t be happier with my purchase or choice of installer!

We had purchased a new house with a faulty HVAC unit. Tom was able to stop by to look at it the same day we found out we needed a new one. From the start, we were very happy with the professionalism, quality, and follow-up that we received when removing our old 30 year old unit and installing a new Goodman unit. The quality of customer service from Tom and his team was very professional. I would recommend Mountainside Air to anyone in the area.

Tom was AMAZING! I called yesterday because our house was freezing cold with our new ecobee system and we didn’t know how to adjust it. He first tried to assist me over the phone and then they were able to schedule me for the very next morning for a visit. He was efficient and helpful in explaining the system and what was incorrect with our wiring. Then he was also able to waive the fee since it was a minor fix. He even let us borrow his ladder to change our air filters. They are an amazing and reliable company and I’ll only be going to them for my hvac needs.

Tom and Mountainside air installed my new AC unit.As a landlord I was in a time crunch to get a new unit in. I reached out to a few different companies. Mountainside won me over with every aspect of company.From the professional phone call in the beginning to the handshake after the installation.A few months after the installation my a thermostat had a glitch. Tom was at my house within 1 hour to quickly fix the problem.Professionalism, timely, efficient, knowledgeable, affordable and reliable. They will forever be my AC company.

Amazing to find a business that is outstanding in AC install & repair. This company really is for the customer. Unlike others which I’m not allowed to give names.I’m a senior live alone in country 50 miles north of Phoenix.When my ac went out I was terrified. No ac company will come this far. My son found Tom & his group. They came to me, checked my ac & told me my 20 yr old ac has died.With in 1 hour they had a crane here to take old AC off roof & put up a new ac. Within 3 hrs I had a new working ac.They returned next day when I called about adjusting temp.This company is far & above others in Phoenix. In Service & customer considered.No worries if you go with this group & Tom

Our parents A/C was probably going, and with parents in their 80's, we couldn't have that. Called and Claire got us is the same day by noon. Tom was right on time, and was great about waiting for my sister to get there, my parents don't do well with strangers. The unit had frozen up and had many small "unrepairable" leaks. so gave us a quote for their unit, same day and scheduled an install for 3 days later. We are so grateful Tom and Claire were able to quickly respond in such a friendly and professional manner. We will probably sign up for the maintenance program, as it is quite reasonable. Thank you Coni, Margie and John

Tom came out to offer us quotes on work that needs to be done as well as quotes for a new system. He was very upfront and went into detail explaining the way various air-conditioning systems work and what our best option would be. We haven't decided what to do yet but, we appreciated his honesty, the low pricing and we feel like we can trust Mountainside to do a great job at a fair price.Update: We decided to replace our unit and we chose to work with Tom and Steve at Mountainside Air. They did an excellent job. They were flexible with scheduling, professional, quick, capable and most importantly, honest. They even gave us an upgraded unit because the one we purchased wasn't going to arrive in time for our scheduled install. We are glad we found a great company and highly recommend them.A year later: While we were out of town our blower broke. We called Mountainside Air and Steve was at our house 5 minutes later to fix the problem. We trust these guys enough to give them a code to enter our home. They got right in and located the issue quickly. They hustled and found the part we need (which is nothing short of a miracle these days). Within just a few hours everything was working again. We highly recommend this company. They are excellent!

We were very happy with our service and our tech was so friendly and helpful.With a hot AZ day, these guys were the only ones who came out the day we called. Thank you again.If you are like me and wondering who to call. Do not hesitate, good honest work. Would recommend for serving your AC needs.

I can't express how happy I am with their service. My a/c went out in the middle of the night. All the big a/c companies were booked out for 3 weeks. Seriously, no joke even for emergency calls. My husband's co-worker knew these guys personally. I called them and within 2 hours they were at my house. They had the part that needed replacing on their truck. My a/c was back up and running within 30 min of their arrivial. The 2 guys were very nice and professional. This is now my new a/c company!!! Thanks again!!!

They were recommended to me & it was my first time calling this company. They were able to get out to fix my broken AC the same day I called. They were on time, fast, efficient, thorough, fair & friendly. They didn't try to sell me anything extra, just replaced the broken part and let me know what I needed to do to keep my system running as long as possible. I was very pleased with my experience with them. I will definitely recommend them and they are now my "go to" AC company.
