System not cooling - 2023 Carrier Heat pump air handler System not cooling due to a clogged drain line and tripped safety switch. The drain line had clogged at the p trap and water had filled up the emergency drain pan and tripped the float switch. I built 2 estimates and the homeowner went with option B. I evacuated the water in the pan, cleared the drain line, added SS1 In-line safety switch, and flushed the pump and drain pipe with 2 gallons of hot water. System is now cooling properly with no other immediate issues. Thank you for choosing T.E. Certified, have a great day!
