We asked This Old House plumbing and heating expert Richard Trethewey to show us the proper steps that a service professional would follow for an oil-burning forced-air furnace; the basics on a gas system are similar. In both, fuel is mixed with air and ignited, heating a sealed chamber. Fresh, filtered air then blows across the outside of the hot chamber and into the heating ducts. (Homes with radiators have boilers instead of furnaces. These heat water instead of air, but the annual checkup is similar.) In all, the dangerous exhaust from the combustion chamber is vented out a flue or chimney.

When a furnace maintenance is performed a combustion analysis should be performed to identify any problems that couldn't be found by a visual inspection. You want to know what the Carbon monoxide level your furnace is producing as well as the oxygen/CO2 levels and stack temperate. The analyzer will also give you a calculated efficiency rating with the information the analyzer receives. You should have >100ppm of Carbon monoxide output during normal operation of your gas furnace. When you have higher numbers or CO numbers increasing during operation their is a problem with the furnace the technician should then find the cause of. This is just a brief explanation I'm trying to get across to those who get their furnace maintained and to those who don't! Check to see if anyone in the company has a NCI certification for carbon monoxide/combustion analysis.

2Be sure the furnace’s circuit breaker is on or that its fuse has not blown. Check both the main electrical panel and any secondary subpanels that supply power to the unit. If the circuit has blown or tripped, reset the circuit breaker by flipping it all the way off and then on again. Or replace the fuse. If the circuit blows again, there is probably a short in the electrical system providing power to the furnace. For this, you may need to call an electrical contractor.
