I was called to a home to repair a broken air conditioner. Upon arrival, I found that the system was not cooling. The thermostat was reading 88 degrees inside. The customer had been without air conditioning for almost a week. They had tried to fix the unit themselves by replacing the thermostat, but the problem persisted. I diagnosed the issue as a clogged drain line. I removed the pump pan and cleaned it with a hose. I then put the pump back in and filled the system with water. The system kicked on heat, and I checked the outside unit. The voltage reading was 24 volts to the O. I checked the tsat and found that it was set to conventional vs heat pump. I inspected the units operation and temperatures and pressures and found that everything was looking great. I called the customer to let them know that the issue had been resolved and to schedule a follow-up appointment for regular maintenance.
