Fan/Furnace not turning on
Problem started last night. Before bed I went to turn the temp down on the thermostat. I got the clicking sound from the thermostat indicating that it was sending a connection to the fan. No fan turned on. I went above the desired temp and it clicked again. Back down below and again another click. Alas, no fan. I checked the breaker in the garage to make sure that it had not tripped for some reason. Turn off and on each breaker to both the AC units and both the furnaces. I checked the thermostat down stairs and no problems. So I went to bed. This morning I decided to test if the heat would come on and got the same problem, click and then nothing. The home is only 5 years only. I must admit, I have never had the HVAC units serviced since I have been here (3 years). I went up into that attic and flipped the switch, (light switch looking) that controls the power to the furnace/blower, on and off.
I am at a loss. Any ideas before I call someone out that I can not afford right now?
