  • "Very Impressed"
    Air Max installed a furnace & a/c combo unit and did a very professional job. Everyone involved with Air Max is helpful and courteous. The owner Keith even stopped back to our house to fix an unrelated repair the day we called in. We were so impressed with the work that was done that we had them come back a few months later to install a humidifier on the new furnace. We highly recommend Air Max and will definitely use them in the future.

  • "Fantastic Company"
    Fantastic company, good quality parts, easy to work with and talk too. 10/10 would recommend!! I had a Reznor garage heater installed and I emphasized the importance to me on the appearance of the install as I have a rather keen attention to detail. In my opinion they did a very good job! And of course the product itself is exceptional as well!
