The service was exceptional! The technician was knowledgeable, professional, and courteous. He went out of his way to make sure we understood what he was doing and why. Our home was being remodeled and Northgate and their service department accommodated the special needs of the construction process. I am extremely pleased with the service we received from Northgate. Our service representative was extremely efficient with both the diagnosis and resolution of the various issues that confronted him. We are very pleased with both the service and the lower than expected service charges.
