“Was not expecting an 87 degree day in April! Our split unit AC turned on but was not cooling. AirMax responded quickly to our service request. Nick was very friendly and professional. He determined the issue, did a temporary fix and gave a plan for the next steps needed. Overall excellent experience!! We will definitely be using them again and highly recommend.“

“Al helped bail me out of a bad install from a different company 18 years ago and I have never forgotten. So when it came time for an update of my current system Cool Air really was the only Company I called......The price was fair and the job was done in a day. As other reviewers mentioned the job was done neatly and the installers including supervisor Stephan were friendly and knowledgeable. I had a small issue with a motorized split damper (which was my original unit) and my thermostat and Al sent a tech guy out who reprogrammed all my thermostats in a matter of minutes and no issues after that. Needless to say we are very happy and would highly recommend them“

“Accelerated installed 2 units for us a few years ago, when mom moved in with us. During the recent heat wave they helped us with a motor replacement on one unit. They were very helpful and worked quickly to get my mom's unit working again. Highly recommend their services.“

“Now that the dust has settled post-move, I just wanted to thank Kathy for helping us get an appointment to our new home during a heatwave! Plus, Matteo was excellent from greeting to goodbye. I WISH ALL OF MY SERVICE APPOINTMENTS were so enjoyable beginning-to-end. I would highly recommend them!!!
