Arrived on site to perform a one system maintenance. Indoor; checked the filter and cleared drain line. Checked electrical connections and amp draw. Found no water safety switch on the unit other than the condensation pump. Recommend installing an overflow switch in the evaporator coil. Outdoor; cleaned condenser coil and checked refrigerant pressures. Checked electrical connections, amp draw, and capacitance. The unit is operating at manufacturer specifications at this time. thank you for your business, we look forward to keeping you comfortable.
