What Happens During a Furnace Inspection

Furnace Inspection Procedure | Plumbing and Heating SpecialistTo keep your furnace operating at its best, it’s important to have it inspected regularly. Ideally, you’ll want an HVAC technician to look at it twice a year (in the spring and fall) so that you can resolve any relatively small problems before they become bigger (and more expensive) to fix.

What happens during a furnace inspection? There is much more to it than changing your filter and making sure that your thermostat works properly. Here is a list of some of the work the technician will accomplish during the inspection.

  • Inspect and clean the furnace’s blower motor, along with the wheel and housing.
  • Check the combustion motor for any obstructions and lint. Clean it if necessary.
  • On a gas furnace, the technician will check for any gas leaks.
  • Perform an inspection on the condensate lines and the pan. If the pan needs draining, the technician will do so.
  • Check the evaporator coil.
  • Inspect the burner; clean it if necessary.
  • Check the ignition, the safety controls and adjust as necessary.
  • Perform an inspection on the heat elements/heat exchanger.
  • Check the flue system for corrosion.
  • Inspect all electrical systems, including the control box, the connections and the wiring.
  • Check the air filters, and replace if necessary.
  • Examine the ductwork for leaks.
  • Run system startup to look for errors.
  • Listen for any sounds that may indicate a problem.
  • Be mindful of any unusual odors. If any are detected, track down their source.
  • Check the furnace system pressures (including high and low side, as well as manifold).
  • Measure temperature rise and adjust.
  • Inspect the vent system while the furnace is on.

This detailed inspection will alert you to a problem with the heating system in its early stages. If you arrange for an inspection before winter sets in, your furnace is much less likely to stop working during cold weather, when it will be waiting for a technician would be most uncomfortable.
