Arrived in Elgin for AC Maintenance, Upon arrival we spoke with the customer, he let us know that his primary drain was clogged. We inspected the indoor unit then spoke with the customer about options for clearing the primary drain line. Customer agreed to sign up for the annual maintenance plan. Customer approved repairs, we cleared the drain line and added drain solution to the primary and secondary drain line, and also installed an inline access port. The system is operating properly at this time.
