Please help me. My ac is not cooling, last year it worked fined after we put in freon
and charged it because we moved the mobile home. Now that i turn the
thermostat from heat to cool,the unit turns on but after 10-15 min a light
buzz noise comes out and the air comes out at normal temp, the compressor
unit outside turns on, I checked the lines to see if there was a freon leak
but lines seemed fine, not frozen . The A-coil is clean, the red light in
the control panel for the deluxe blend air is flashing( but I thought that only affects the furnace) and when the AC is on the green light stays on. What could be the problem?
