This company installed my AC unit and have done my maintenance since 2021. The techs are always on time, knowledgeable and friendly.

The technician came to my house for a late evening service call, checked the entire system, and was able to diagnose the issue. He was professional, knowledgeable, and respectful. I would recommend this company. read more

Sold our house, and the buyers inspection revealed a couple of issues we didn't know about. A/C drip pan in the attic rusty, and drain line possibly plugged. Since I had such a good experience with this company a couple of years ago, gave them a call. Efficiently scheduled appointment. Technician showed up on time. Thoroughly professional gent fixed the problems for the price I was originally quoted. I highly recommend this Company. Their standards and behavior have been exceptional! read more

I had a new a/c and heating system installed. Northern Air Mechanical Services contacted me when my unit was available, quoted me better and best prices, and worked with my schedule to arrange an installation day to replace my old system. The old system was too small for the size of my house-- it barely passed inspection -- and as it has gotten hotter and will continue to get hotter in AZ, it was important to me to purchase a larger, more reliable and efficient system than what I had. The installers were exceptional -- meticulous, careful, thorough, professional, and kept me informed throughout the process. It was an all day project, which I anticipated and I am glad they took the time to ensure everything was done according to the system requirements. I trust Northern Air Mechanical Services to do the best job possible. I have been very pleased with their system maintenance throughout the past couple of years; they take pride in their work. As I have mentioned before, they are professional, thorough, thoughtful, knowledgeable, and informative. I highly recommend them. read more

Needed a new A/C unit installed because dog had been urinating on the previous outdoor system. Spoke with Jason who was able to get me a reasonable quote for a new unit installed. They were very patient and listened to my concerns as I had just been ripped off by a different competing place who had been out three times including charging us for coolant when it was spot on obvious there was corrosion and a leak (I do not recommend Simply The Best). Jason provided the quote and the install was done within a few days which is excellent response time considering I was in a jam and summer is here. Installers were very professional and even had the job done under the quoted time frame and did preventative maintenance on the other existing unit. Recommended. Straight forward, friendly and professional and don't play games with you like some of the other guys. We need integrity living in Arizona with the heat and I can say based on my experience, Northern Air provides exactly that! Thanks again and will use in the future for all cooling and heating needs! read more

Fast, courteous and on time. Overall a good experience. Appreciated the friendly service as well. read more

Paul was the technician that serviced our A/C for routine maintenance. He was prompt and I also received a courtesy phone call with ETA before he made his way over to our house which I GREATLY appreciated. He was very professional and explained the work he had completed and also the proposed preventative work he recommends we get done to ensure our unit lasts as long as possible before having to replace it. I recommend Northern Air Mechanical Services and will continue to use them for maintenance services and repairs if ever needed. read more

THESE GUYS ARE THE BEST!!! They are HONEST, TRUSTWORTHY, VERY FAIR PRICED, DEPENDABLE, AND their work is TOP NOTCH!!! I called out 5 AC Companies to give me quotes for moving my AC , cleaning the coils Inside and out and changing the capacitor. Northern Air charged WAY LESS than the others and did an excellent job!! My Heat pump AC is running better than ever!! I asked Jason for a price on a new AC unit and he said I didn't need one. MOST would want to upsell but Jason cared more about my pocket book than his own. I now have a RELIABLE AC Company I KNOW I can depend on who's not out to rip me off!! THANK YOU Jason!!!!! 10 Stars!!! read more

Excellent service. Went to great lengths to solve a pesky problem and make things right. Always professional.

Great response and communication- Jason supplied a through quote at a great price and offered many options. Arrived on time and was helpful!

Had a great experience with Northern air. They came and worked with me on a project converting a garage in to a work space. Jason was super communicative. Gave me good info on the best path to take. Cody came out to so the install, he was also great, ran in to some unexpected challenges but handled it like a pro. Jason followed up after the job was complete to remind me that if I have any issues to reach out and they would take good care of the work and any issues that arose. Perfect customer service and you can see that as it's reflected in the ratings! Big respect for running your biz the way you do! 10/10 read more

My AC went on a Sunday afternoon - they responded within 2 hours, diagnosed that my 27 year old heat pump was beyond repair and early the next day I received the bid for a new unit/replacement - I got two other comp bids and they were just slightly the low bid but even more importantly were able to schedule the unit replacement for just 2 days later. All work was done professionally and on time for a fair price. Highly recommend! read more

Had Paul as my rep from Northern Air. This company is great! Referred by my Uncle as a reputable trustworthy company. Completely transparent, fair pricing and ontime service. Thank you for your earning my business! read more

I needed to replace my 20 year old ac split system. I was referred to a friends son that did these kinds of jobs. Once I received the quote with a supposed discount I was not happy and the information I received did not sound right to me, I did not feel comfortable at all. I decided to contact Northern Air for a quote. I spoke with Jason. He took the time to explain everything about what I needed and gave me the most useful information about ac units and new refrigerant. I learned a lot. I received the quote and was very satisfied with it and felt comfortable going with Jason's company. My system was installed yesterday and I want to thank Jason, Doug and the other guys that were here working on my new installation. All the guys were very courteous and respectful. They informed me every step of the way on the progress. They were all very professional and cleaned everything up after they were done. Doug walked me through everything and made sure everything was working properly before he left. All these guys are very intelligent and know their craftsmanship. I would recommend this quality company to anyone looking for AC service/repair/installation. Thank you Jason and crew for a great job! read more

Adam was out today to maintenance our AC units. Very personable and friendly. Thank you for your service

I sent an inquiry through Yelp.com for a preventative maintenance estimate and Jason was the only one to not only get back to me quickly but gave a detailed description of what the technician was going to do and exactly how much. The other companies didn't so this. Day of service Shane gave me a call of when they would be at my house. Shane and Scott showed up and got the job done efficiently. I'll be checking in with them on some other service issues down the road. read more

Northern Air Mech Service was awesome. They were timely, explained everything, fixed what needed to be fixed and didn't try to sell me. In other words they were honest. Pricing was also very reasonable. They are now my go to company for air conditioning. read more

I am typing this review from the comfort of my unbelievably cool home right now. They responded to my inquiry immediately. It wasn't an emergency so next day service was more than ok. Doug came and recharged one of my units that was desperately low. You can tell he has a passion for what he does. He was so happy when his thermometer readings got where he wanted them to be. When the cool air flowed through my upstairs vents, I got emotional too. This AZ heat is no joke y'all. He even showed me how to get my rooms a little cooler by helping the air flow. I am so grateful. I will never use another AC repair company again. read more

I realized that in my original review I wrote UNhappy when I meant to say HAPPY. Darn talk-to-text! I think it was clear from my entire review that's what i meant though :) But posting this update just in case anyone is confused (was re reading the review cause I screenshot it to someone on the nextdoor app to recommend them to a neighbor)! read more

I highly recommend Northern Air for any of your Cooling or Heating issues!! They are knowledgeable and take the time to explain the problem and answer questions. I was very pleased with their price as well! It did not cost me an arm, a leg and a kidney to fix my AC cooling issues. I will be using them for any problems in the future. read more

Totally professional, punctual, knowledgeable, and competitive. Our old A/C unit (12 years)was still working fine but we knew its end was in sight. Had numerous bids and visits from large companies, and smaller companies. The bids ranged from $4500-15000. We selected Northern Air Mechanical Services based in San Tan Valley even though they were not the cheapest. But their bid was fair, not loaded with stuff I didn't need, or need to read etc. The installation was on time and the entire process well exceeded our expectations. My thanks to Jason and the installment team of Scott and Travis. read more

Northern Air Mechanical Services Needs TEN Stars! Super Fast Response. The tech. Scott did NOT fail to check EVERY aspect of my AC unit inside and out. Never did he try to UP-SELL me on anything. I know more about AC units and the internals of them then I let Scott Know. Honest in EVERY detail. The cost was less than others (who wanted to ONLY sell me a NEW unit) that I contacted. 110% ALL THE WAY. read more

Good honest folks that tell you exactly if you have a problem, and are straight with how your AC should work. I had a bad experience with another company and asked these guys to do a freon leak test, their rate was one of the best and they helped me understand possible causes for the leak. Will use again! read more

Very prompt and fair quote. The lady who I corresponded with (Tiffany?) was very nice too. I will use Northern Air in the future for any of my HVAC needs. read more

Again, just great service. I can't be any happier with a A/C company than i'm with Northern Air, Thank You again Jason for coming out to my home and checked out the heater for the winter (cold) months we have here in Arizona. I'll see you around April. read more

I would recommend Northern Air as they did a great job and they were honest and upfront about the issues. I would do business with them again. Their prices were very reasonable as well. Thanks Jason read more

Happy to update this review after Nothern air took the time to reach out to me, find a contractor who would fix out attic, and promptly had it fixed. Thanks again to the hard work, customer service, and responsiveness of this team! read more

What a great experience. When I had AC problems, Northern Air responded quickly to my quote request and was able to come out the next day. Not only did technician Doug fix the problem, he gave a detailed explanation of what he was doing during each step of the process, alerted me to potential problems, and gave some great maintenance tips to help avoid future issues. Fast, friendly, fair, and thorough. That's about as good as it gets with any company. I won't be going anywhere else for future AC and heating issues. read more

Northern Air kept my A/C running for 17 years and they have come out to service my A/C since 2015. They treat you like a customer/ friend and not just some work order. I had Northern Air replace my old unit this past week. Extremely happy with the whole process from start to finish. I wouldn't call anyone else to service or replace my A/C unit. I highly recommend them! read more

Our 16 year old Lennox ac unit stopped blowing cold air on Saturday. After going thru the hassle of calling and emailing companies, I settled on an appointment with Parker & sons for the following Monday. I didn't realize how bad the reviews were till I checked Yelp. I cancelled my appointment with them. After checking Yelp, and reading every review on Jason and Northern Air, I called and Jason was able to make it out Monday at 3pm. Let me say, I am relieved that Jason was able to come out. He quickly diagnosed the problem as low Freon and a possible leak in the case coil. He explained how these things happen, and knowing a little bit about hvac myself, I understood everything he was saying. He suggested putting Freon in it for now to save some money till we see what happens with the possible sale of our house and gave me options for replacing the unit which were very reasonable in prices. He did not try to up sell me. I will definitely be calling Jason back again to replace the unit should I keep this house and I will use Northern Air no matter where my next house in the valley will be. HIGHLY RECOMMENDED!!!! I've had bad experiences with other companies over my 25 years and 3 houses in the valley. Northern Air will forever get my business from now on. THANK YOU JASON!! read more

My air conditioner went out one evening so I called a few companies to help fix it. Northern Air was able to schedule a visit early the next morning. So I only had to handle one night without a working AC. Tiffany was great on the phone and answered all my questions. They arrived and told me my unit had blown a fuse and they fixed it. When they arrived, I asked if they could service and tune up the unit for the summer since I had not done that this year. Overall, they were great. When the job was completed he showed me the bill explaining every charge on the invoice. Which gave me peace of mind because so many don't explain, they just give a total and ask for a card. I would recommend them and will use them again in the future. read more

Great experience from first discussions with Jason through installation. Timely, professional and great to work with, made sure we understood the project and what to expect. Great result. Highly recommend. read more

Jason was phenomenal. His response time was very prompt, and he diagnosed the issue right away. He was courteous, and took extra time to explain exactly what needed to be fixed and why. His pricing was very fair. I am not mechanically inclined, so the thorough explanation was greatly appreciated. I would not hesitate to recommend Northern to others after my experience with Jason. read more

Fast response to yelp quote request. They were able to schedule a tech to come out within the same week. Technician was friendly and knowledgeable over the phone. read more

Father's Day Sunday. 117 degrees at 6:00 PM. I lucked out and Jason at Northern Air answered his phone. I got his number from our neighborhood website NEXTDOOR that others had had a good experience with him. Luckily he was able to service our AC unit immediately and showed up at 6:30 for his 6:30 - 7:00 window. He thoroughly checked everything and diagnosed the problem. I didn't describe it too well on the phone. I would highly recommend Northern Air! read more

Northern Air Mechanical Services is the Best! We only call them when we need service on our HVAC. Recently we had an issue with our AC. Northern Air Mechanical Services came out and found the issue was only a short in a wire. They replaced the wire with No Charge! Thank Again Northern Air Mechanical Services! read more

Northern Air is awesome and I would highly recommend them. I own a rental property in the area and the air conditioning unit has been giving me problems. The property management sent their preferred vendor to fix the problem but a week later, it broke again. The vendor was going to charge me another ridiculous amount and it did not seem right to me. I looked on Yelp in hopes of getting a 2nd opinion and found all the great reviews about Northern Air. I decided to call them and spoke to Tiffany who was super nice and stated she could send Jason to diagnose the problem on the same day. Once Jason got there, he told me whoever fixed the unit did not connect the unit properly. He not only fixed it properly but he charged me a significantly lower rate than the other guy. Thank you, Northern Air, for being accommodating, knowledgeable, efficient, and most importantly, honest! read more

Excellent family owned business!! I can't say enough great things about Northern Air. Every time we've used them over the last few years they've been responsive, friendly, very reasonable & just extremely great people to work with. Highly recommend, you'll not be disappointed! read more
