Last night we noticed our AC was out. It was late but we decided to call the on-call technician, Louis, and he came right out to our house and did a thorough check of our system. He found several issues, showed us pictures of the problems (frayed writing, corroded parts, refrigerant low), and fixed them on the spot. I cannot recommend Louis highly enough - he is fantastic and we are grateful for his expertise and help last night! We have been using All Service for many, many years for good reason - they are reliable, fair, honest, and fast. Thank you!!
