Furnace tune-up and safety check
A furnace tune-up cleans the flame sensor, checks the ignitor, burners, gas pressure and venting, tests for carbon monoxide, and inspects the heat exchanger. Doing it in September or October avoids the rush when the first cold front hits.

The first cold snap of the year brings a wave of no-heat calls in the metro. A fall safety check finds the dirty flame sensor or cracked ignitor before you need the heat.
The combustion and carbon monoxide check matters most for older furnaces and homes where the water heater shares the chimney.
