Henry not only arrived very promptly but he was also extremely professional and thorough. He was courteous and affable. The only observation I might make is that Henry apparently changed the dehumidifier settings of our thermostat without alerting us. Notwithstanding are pleased and will very gladly continue to work with McCullough for our A/C maintenance and repair.

Great service when my AC stopped working on the weekend. Very happy with the technician that came out and that it was fixed under warranty. Thanks McCullough!
