• This HVAC install experience was stellar. One of my AC units died in July and I decided it was time to replace both 20+ year old HVAC systems in my home. Couldn’t be happier with the whole experience from the friendly receptionist, the quote process with Ryan and follow up emails, great pricing and installation timing, excellent handling of Mass Save rebates, and a quick 2.5 day install from a knowledgeable, professional, and friendly team. Had two heat pumps, two gas furnaces, and one steam humidifier installed, overcoming some challenging plumbing situations to make it sure it was done right. Would highly recommend.

• On Sunday our central ac decided not to work. We reached out to AAir Systems Technologies who installed our system. Because it was Sunday we got the answering service and had to leave a message. We received a call back within 15 minutes from the owner Ryan who assured us our issue would be dealt with Monday morning. Sure enough his tech named Tyler showed up Monday morning and diagnosed the problem. I was so impressed with him! So knowledgeable and so personable! Unfortunately they didn't have the part we needed however Tyler said I will make sure we have it tomorrow (Tuesday) and I will be back to install it. Tyler arrived Tuesday afternoon with the replacement part, I had to leave for an appointment so I asked that he just close the door when he was done. When I came home I found a note above my thermostat from Tyler that said my ac was all set and to have a nice summer! I was blown away! This is ABOVE AND BEYOND great customer service! Nice work AAir! And the world needs more Tylers!

• Great company, at all levels. Ryan was great at answering all my questions and concerns when he came by to provide estimates on multiple projects. Tina was fantastic every time I called or emailed. She was particularly helpful in dealing with MassSave. Trevor and team were timely, friendly and professional during the installs. I had AAIR install a heatpump and two mini splits as well as change the ducting for my existing forced hot air furnace. I will 100% call them for any future HVAC needs.

• In Ryan and his team I trust! From my initial phone call to request a quote Ryan was responsive, polite, professional and patient with all our questions. He walked my wife and I through multiple options in replacing our whole house heating and air conditioning system. We narrowed it down to two possibilities, so I called Ryan again and we went through all the pros & cons to each and settle on what was best for us. Then he passed us on to Tina to help us through the Mass Save loan process. She was awesome! She is well versed in the process so it went smoothly. We were approved in a short time and were able to schedule the work. Then the team arrived and it was like watching a well organized work site. From set up to the clean up they were clean, efficient, polite and knowledgeable. Once finished I was instructed on how the run the system and it’s been every thing that was told it would be. My over all experience is extremely satisfied and would highly recommend Ryan and his team for all your HVAC needs. Thank you AAIR Systems

• They did work on my unit less than a year ago. Recharged for almost $1400 with labor stating that the wrong refrigerant had been added to the system. I’ve called them a good 8 times the last couple of weeks, since the system is still running through the same issues. They told me they had to check to see if they still have the refrigerant R-22. Which isn’t the issue here nor was it then. It’s blowing & was blowing cool air but not enough of it. They’ve yet to call me back. Never met a more unprofessional business. Dont waste your time or hard earned money.

• AAIR system came to install both furnaces and heat pump in hour hose when one of our furnace died. They were very swift and did it in 2 and a half days. They made sure we had heat all the times. Everyone of them were very kind and did the job beautifully. They have been doing our services for several years. Professionalism at best. Among all the contractors who have done jobs in our home, this group of gentlemen are the best. Please try them and you will not be disappointed. They even got me the rebate $5400.00. Thanks AAIR SYSTEMS

• Aair systems recently replaced our upstairs air conditioning and did a fantastic job. They were great from the start of the process to the end. They also facilitated our mass save rebate really quickly. I highly recommend.

• The whole team was a pleasure to have in the house for 2 day job installing a new 4 unit mini split system. What an easy-going & hard-working team. Great communication from start to finish! Would definitely recommend to anyone who needs mini split service or installation.

• Friendly staff. Installed a heat pump system in our home. We had one issue soon after install, but they came out right away a solved the problem quickly. No problems since and it’s been over a month now. I would use again.

• Outstanding Mini‑Split Installation by AAir Systems Technologies I couldn’t be happier with the mini‑split system AAir Systems Technologies installed in my home. From the very first interaction, their team was professional, responsive, and genuinely focused on finding the right solution for my space. They took the time to explain my options clearly, answered all of my questions without rushing, and provided a fair, transparent quote. On installation day, the technicians arrived on time, worked efficiently, and treated my home with care—everything was neat, clean, and well organized throughout the process. The mini‑split itself works flawlessly and has made an immediate difference in comfort and efficiency. You can tell the installation was done with real expertise and attention to detail. They walked me through how to use the system, made sure everything was running perfectly, and didn’t leave until I was completely satisfied. AAir Systems Technologies delivers exactly what you hope for in a contractor: quality workmanship, honest communication, and excellent customer service. I would confidently recommend them to anyone considering a mini‑split or any HVAC work. Truly a top‑notch experience from start to finish.
