Only System - Not cooling 2020 Lennox AC not cooling due to a tripped safety switch in the pan. The drain line was backed up and had leaked into the pan. I presented a couple options and the homeowner with option B. I cleaned the drain line, evacuated the water, and tested the equipment. Homeowner is now on our Homecare plan and we owe him 2 hvac visits and an electrical inspection. Thank you for choosing T.E. Certified, have a great evening!
