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.

An annual inspection of your unit can ensure that the various potential problems mentioned above are detected early, and before they require complete replacement. During this inspection, for instance, a professional might find small cracks in your heat exchanger or a faulty seal in your blower motor. Some manufacturer's warranties even require these annual inspections to maintain validity. Typically, your furnace inspection will cost between $80 and $150 depending on the area in which you live and the professional you work with.
If your heater is relatively new, we will be able to repair it. If your furnace is antique, we will fix it if it can operate safely. The HVAC technician can check for cracks in the heat exchanger. Cracks can leak dangerous exhaust fumes into your living space. Sometimes, repairing a damaged furnace is more expensive and less efficient than replacing it.

@Neil What is the use of repeating lessons when there is so much more to be learned? Technology has moved on from the adz. Plumbers use PEC, insulation is sprayed, glue-lams allow for open floor plans and furnaces are no longer stoked with coal. As for the new people, if these trades cannot attract fresh blood we will all be unable to get homes built and repairs made. I don't yearn for my first home with the leaky concrete block foundation, failing well pump and an oil furnace held up by the plenum. I'll take heat pumps, solar panels and PVC waste pipes any day.You can get all the sill plate repairs and flitch beams demos you need on YouTube.
