McCullough is a top shelf company. Their technician EJ Pittaway did an excellent job solving and repairing my A/C problems. I called on a Sunday, made an appointment for Monday and was fixed by that early afternoon.

We have used McCullough for 10 years for both new installations as well as repairs on existing units and have always had a great experience! They came highly recommended by a friend who owns multiple rental properties and has used them for 30 years
