I stopped by to make an appointment for A/C system recharge. They had an open bay and Dan, the manager, said they could do it now (it would take about an hour, he said) or make an appointment for later. I decided to have it done then. They completed the job in abut 45 minutes and Dan explained exactly was was done. Since I had stopped on my way home, I did not have the coupon with me but Dan gave me $25 off for the coupon. I have been going to this Shell station for a long time. Always get honest and great service!
