I had not used Rainaldi prior to this appointment. But I needed a to have my a/c serviced prior to an international trip and I called them. So happy I did :) David came over the day after my call. After he left I thought there seemed to be a problem with the cooling. I was due to travel the following day and was frantic when I called Rainaldi. Davaid was due to be off on the next day, but at 8 a.m. he was at my door. He thoroughly rechecked my a/c system, leaving me with a much lower stress level, and peace of mind for my trip. So glad I called Rainaldi, Thanks David!
