Efficient AC tune-up service

I recently had Grandmark Service Company come out to do a tune-up on my AC unit before the summer heat hit. The technician was punctual, courteous, and very knowledgeable. He took the time to explain what he was doing and gave me some useful tips on maintaining my system. I was impressed with the thoroughness of the service and the reasonable price. My AC is now running smoothly, and I'm confident it will keep me cool all summer long.
