We are regular customers of Airflow Service Company. We are signed up for their routine maintenance contract which has been working well. We did recently have them come out to service a small air conditioning unit of ours. They had to work on the mini-split system. Unfortunately, one of the two technicians did not have the right adapters with him. So they sent him back out the next day to finish up the job. He recharged what he needed to. Now, everything is working properly. So far, so good. Every time that we have technicians come out they have always been courteous and timely. We recommend the company all of the time. We continue using Airflow Service Company for their quick responsiveness.
