My furnace conked out a couple weeks ago. At first, I called in a company I had used in the past. They replaced the heat exchanger, which was under warranty. But then there was a problem with the blower motor, a very expensive part to replace. Finally I realized I had to replace the furnace completely. Adam’s Air gave me the best quote of three companies and they were able to replace the furnace the next day. The team worked efficiently and I appreciated Shelley who arranged to loan me a couple heaters in the mean time. A satisfied customer.

I had issues with my Goodman Furnace - no heat!!!..and after some thorough research came across Adam’s Air Systems on Google - it’s hard finding a local company who cares/know what they are doing/loves what they do and communicates well. I had contacted a few people in Hamilton and some people didn’t get back to me, didn’t understand the issue or seemed like a scam. I persevered and came across Adam’s - from their website, reviews to communicating with Adam - I knew these were the guys to go with. I also love to support local family businesses, which they are! Adam answered my call - was super professional and kind. He listened carefully - was able to reassure and have Brendan come out quickly to take a look. Brendan immediately diagnosed the situation and they both got the part needed and organized quickly. They also understood about the warranty side of things that I was dealing with and made sure everything was in order their end as well. Even though they had other jobs going on, they danced between them beautifully making sure I felt like a priority and again, communication was amazing. Brendan came back the next day, part in hand, checked everything over, even pointing out some things we had no idea about and fixed two other small issues. He also took the time to explain what was going on, why things worked a certain way. It was good, honest no messing you around advice. You can tell Adam and Brendan actually care about what they do and want to give the best service. We will be having them back to service our air conditioner and fireplace. I highly recommend Adam’s!!

Adams Air has handled multiple HVAC projects for us across several properties, and they always go above and beyond expectations. Adam is fantastic to work with—professional, knowledgeable, and personable—and the same goes for his entire team. They've installed furnaces and central air systems with expertise, and their deep knowledge of the field really shows. We were especially impressed when they relocated a furnace from one part of our rental property to an entirely different location; the job was done perfectly, and we're thrilled with the outcome. Highly recommend—five stars all the way for Adam's Air and their outstanding staff!"

A few years ago I contacted Adam’s Air when I needed a new AC unit. Their work was exemplary in all respects and they have provided exceptional service whenever I’ve requested it. So it was only natural that I would call them last week when my 28 year old furnace was ready the breathe its last. And no surprise, Adams Air gave me excellent options, fair pricing and a new furnace in no time. They are quick to respond, informative, efficient and professional. Their work is first rate, with evident attention to detail. They go the extra mile to provide service excellence and a superior customer experience. My absolute and unqualified highest recommendation to everyone at Adam’s Air. You guys are the best.

I emailed them via their website for a furnace inspection. They got back to me quickly and I was able to book it for the next day. The tech who came over was friendly, knowledgable, willing to answer my questions and tell me what he was doing. Absolutely no upselling or pressure tactics whatsoever - just good, honest service. The price was very reasonable too. Will definitely be coming back!
