Function: The furnace and heating system of a house in North America, should be sized properly to provide adequate heat on the coldest day, in a safe and reliable fashion. All rooms in a house designated as a "living area" should have an adequate heat supply.

What We Look At: Is the furnace sized properly for the house and do all living areas have a heat supply?  Is there evidence of a "do-it-yourself" installation,  unsafe modifications, etc.?  A digital carbon monoxide test is performed to check for unsafe levels of CO in breathing air & in combustion gasses.  Typically, a furnace has three basic components: the burner, the blower, and the heat exchanger.  All three of these components has to be working properly for the furnace to operate safely.  

Typical problems we see are: High levels of carbon monoxide; corrosion, debris & rusting on the interior (one furnace filter was so plugged with dirt that suction from the blower motor pulled it inside the fan housing - every time the furnace started, it made a "flapping" noise.  That's when the homeowner called me to investigate the "bird" in his furnace!); irregular burn pattern on the burners; unsafe chimney venting; insufficient combustion air supply; etc.
