American Air Systems, Inc. is a heating and air conditioning company in Conway, NH. Its website says it works on all makes and models of heating and air conditioning systems and is an authorized dealer for York, Trane, Mitsubishi, Lennox and others, and the company says it has been in business 10 years. A recent customer had mini-split systems installed in a log cabin. That customer said Vicki handled scheduling and follow-up, Brandon specified the units and answered questions about sizing, and Tyler led the installation; Tyler and Keagan treated the home with respect, the customer wrote. A 2025 customer said a new furnace was installed, from the initial furnace inspection and consultation through the three men who completed the job. A 2025 reviewer wrote that the company had installed their mini split 10 years earlier, responded quickly when its cooling started to decline, and that technician Caleb analyzed the issues; the reviewer said the system was performing great again. A 2025 customer said the company did yearly maintenance on both of their mini-splits and, after a call about an issue on a Tuesday, came out on the Wednesday and fixed the problem. A 2024 customer wrote that after their first yearly cleaning they emailed with a question about the vanes, got a response in under an hour, and had a technician at the house less than two hours after that. That 2024 customer also said the unit had been installed a month and a half before the earliest estimated installation date, and that the rebate documentation was sent out the day the bill was paid. A recent customer described a leak in a pipe from the condenser to the air handler: they said the company sold them a new air handler and condenser, which did not fix the problem, and the next year told them a service call would cost. In a 2026 update to that review, the customer wrote that they had heard good things about the company recently and not to take too much stock in an experience from so long ago. A New Hampshire HVAC licence, number GFE0802688, is active on the state registry under holder of record ALEXANDER J DEWEES. The Better Business Bureau grades the company A+, and it holds 3.9 stars from 18 Google ratings.
We had American Air Systems of Conway, NH install mini-split systems in our log cabin, and the entire experience was excellent from start to finish. Vicki was great to work with on scheduling and follow-up, making the whole process smooth from our end. Brandon did a great job specifying the right units for the job and patiently answered all my questions about sizing. Tyler led the installation and was professional, knowledgeable, and thorough throughout. He and Keagan treated our home with real respect, were courteous the whole time, and clearly took pride in their work — the craftsmanship was excellent. The installation went flawlessly, and we couldn't be happier with the results. I'd highly recommend American Air Systems, Vicki, Brandon, Tyler, and Keagan to anyone looking for quality HVAC work from a genuinely professional team. Great job all around!
Had a leak in a pipe from condenser to air handler, they sold me on a new air handler and condenser. Obviously didn’t fix the problem. The next year told me it would cost for a service call. When we fixed the pipe eventually with another contractor, the system flooded my attic and all down through the walls. Then couldn’t figure that out. Still not draining 5 years later. 2026 update: I have heard good things about this company recently, don't don't take too much stock in my experience from so long ago.
American Air Systems was quick to respond and very professional throughout the entire process. I had a new furnace installed and everyone that I worked with, from the initial furnace inspection and consultation, to the three men who completed the job were top-notch professionals. Thank you, Team!
American Air Systems installed our mini split 10 years ago. When the system recently started showing signs of declining cooling, American responded quickly. Caleb, technician, was courteous, professional and friendly. He analyzed the issues, the system and determined best course of action. System is performing great again.
They do my yearly maintenance on both my mini-splits. Always clean and professional. Called them on am issue on a Tuesday and they came on a Wednesday. It was on July 8th and they were here and fixed the problem on July 9th. Talk about great customer service. Thank you!!!
