Everything with Aire Serv Heating & Air Conditioning of Orange County has been great. We use them for our business, and we've been very happy with their services. We had an incident last month when our air conditioner was not working properly. We called them up, and they responded immediately. They sent someone to fix it right away. The technician who came to help was excellent. He was well educated, and we would recommend him specifically if we could. He figured out that the filters were not changed and that there was ice building up. After he fixed it, the air conditioner worked perfectly again. Air Serv is very reliable. We will continue using them.
