my centrail air conditioner comes on but the furnace will not. i think maybe the wires may have been pulled out of the thermostat but i don't knowe for sure. everything looks fine as far as the wiring goes, but when the wuires are juggled in a certain way the furnace comes on. please help. i've got 3 people with asthma in this house and i can't afford for someone to come out.
thanks!

Sounds like a loose or broken wire at the thermostat. Look at the connections very carefully. Carefully move ONE wire at a time. The wire to the G terminal (green?) is the one that serves the AC fan (which is located in your furnace).
