Furnace not heating to right temputure
A while back we had problems with our furnace not heating to the right temputure. Had it serviced several times, because they couldn't figure out the problem. Then they figured out that water was getting in the motor so my husband disconnected the tube that runs down the unit to the motor. This morning I woke up and it felt cold so I checked the thermostat and it was 72. We have it set on 74. I turned it off and then back on and it was fine for a few hours and now it's back at 72. Furnace keeps coming on and off so I don't know what the problem could be, any ideas?
