Furnace starts then stops

A heat exchanger is used to transfer and separate the heat generated from the burners to the home's air supply. If the heat exchanger develops a crack or becomes clogged,  dangerous fumes can mix with the air being circulated throughout the home. For this reason, the furnace shoud be checked annually by a qualfied technician and carbon dioxide detectors should be placed in bedrooms and other frequently-used living areas.

Furnace burners won't stay lit

Furnace takes too long to heat the home

Strange smells coming from furnace

On a gas furnace the heat exchanger keeps the spent gasses from entering the living or working areas of a home or business. If the heat exchanger is cracked the spent gases containing hazardous carbon monoxide can mix with the heated air causing serious health risk or even death. Although carbon monoxide itself does not have a smell the other fumes can produce a slight burnt or chemical smell. 


Furnace is frequently cycling/short cycling

A cracked heat exchanger can allow the hotter gas burner fumes to mix with the circulating room air. This can cause the furnace to cycle off faster but, more importantly, is a health hazard due to carbon monoxide from the burner fumes entering the home.
