Our AC stopped cooling overnight, and they responded the same day. They replaced a faulty capacitor, and everything has been running perfectly since.

We had a refrigerant leak in our condenser line that was causing our AC to freeze up. They found the leak, repaired it, and recharged the system correctly. Six months later, still running perfectly
