Paul was waiting for me at my house as soon as I got home from work. As soon as Paul was waitng for me at my home when I left work. I parked my truck and he jumped up and got right into flushing my cooling system! Had heat within 25 minutes! He is very knowledgeable about the job he is a pleasure to talk to. He described what he was doing step-by-step and helped me understand what was going on. I would definitely want Paul for any future issues I might have with our vehicles.
