Cool Customers
Definitely recommend Highland AC! I needed yearly maintenance. Everything looked great. They also explained how to improve air quality, which is very important with 3 indoor cats.

James T.
When our AC had a drainage issue, the owner of Highland AC called me back immediately to diagnose the problem. The technician, Kevin, was out later that afternoon to fix it and even did a maintenance check on our unit. For great communication and professional service, we highly recommend Highland AC.
