You probably never think about your furnace until it starts blowing cold air. Relax. It’s not time to panic. The solution could be simple, though it may require some help from a professional. Here are a couple common reasons why your furnace has decided to stop working.


One of the most common reasons an older furnace is blowing cold air is that the pilot light went out. Sometimes, this simply requires is a flashlight and a read of the manufacturer’s instructions, usually located on the inside door of the furnace. If it doesn’t stay lit, contact a heater repair specialist in Dayton. There may be something wrong with your furnace that’s a potential fire hazard. Usually, the pilot blows out because soot has clogged the port, leaving the pilot flame too weak to stay lit. This is not a safe repair for a homeowner, but pilot cleaning is relatively simple for a professional furnace technician.


For a modern furnace, the most common failure point is the flame sensor. The flame sensor is a safety device that passes an electrical current through the flame telling the furnace that it has safely lit and can continue operation. When the sensor gets dirty, it cannot properly sense the flame and the furnace will not stay lit. While it may simply need cleaned, sometimes we find that the protective coating is burnt off and a new sensor is the most reliable solution.

If you can’t diagnose and fix the problem yourself, contact a professional. It could be routine maintenance or a potentially dangerous problem.
