Our air conditioner was freezing up and not cooling properly. At this time of the year, we need that cooling air in our house with a full walk out basement and lots of windows on the West side of the house. We called yesterday and John came this morning and we now have cool air again. What a relief. John did a thorough inspection and added coolant. Whenever he was in the house he had on his cute little blue booties over his shoes. There is never a mess when John is done. We appreciate the fast service.
