Why is my furnace blowing cold air?

This could be a pilot light or ignitor problem, gas valve issue, or the fan running without the burners operating. A technician can diagnose the specific cause.

Is a furnace that won't heat an emergency?

During cold weather, yes - especially if you have elderly residents, children, or medical concerns. We offer emergency heating repair service.
