Words cannot describe how much I appreciate AirTech, especially Julie Dunn, the administrator, and of course the technicians that come out to service our unit. Calls are always answered the same day if not immediately, all the staff incredibly knowledgeable. A company that values customer service and integrity in their work. As a small business owner, the need to get things done asap is imminent to running a successful operation and I thank Airtech for always being dependable and reliable. I highly recommend this company for all your hvac needs and I will definitely be using them to service my home when the need arises. Please note I only input the cost for my service calls. Cost will of course vary case by case.
