  • "Excellent Job"
    Air Max did an excellent job! They explained the work to me and were professional in everything that they did. They worked really hard. I would highly recommend Air Max LLC. Thanks!

  • "Very Professional"
    Evan was very professional and easy to work with. Our job was completed on time and on quoted price.
    - Christina D.
  • "Highly Recommend"
    I highly recommend them! Their service, pricing and professionalism was excellent. I experienced flooding and needed my furnace checked, serviced and cleaned. I was not familiar with companies in that area so was a bit nervous but they exceeded all of my expectations. They were prompt and didn't try to add things on- in fact, they went above and beyond to assist me. I will definitely us them for other services (duct cleaning) and in the future. Kala was especially helpful in coordinating my service and responding to questions. Excellent integrity and service all around.

  • "Thorough and Detailed"
    Alex was very good. Understood the problem & spent the necessary time to ensure the cleaning was completed properly.
    - Dennis O.
  • "Honest Service with Integrity"
    I highly recommend this company. They did an excellent job of reconnecting an existing air conditioning unit after we had landscaping work done. Another company was more interested in selling a new unit than providing an honest assessment of the possibility of getting more time out of an existing unit. Thank you Air Max for your honesty and integrity.
    - Eric O.
  • "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!
