This is a Bryant unit. It is unusually warm outside Dec 20th.

Thanks

Do you get hot air if you put the Fan to the On position?
Is anything connected to your thermostat L terminal?

Saw that the other day. Bad furnace control board relay for heat coils, stuck on and apparently the board was NOT smart enough to kick on the blower. Could have burned the house down if not taken care of. That was a York unit but almost all manufacturers use the same ole control boards. The heat coils have a safety limit switch to keep them from overheating but if that fails it can overheat to the point of starting a fire and burning your house down. Turn the main breaker off until you can have it serviced.
