The Annual Furnace Tune-Up

Furnaces become dirty reducing energy efficiency and potentially reducing the units service life. Routine service should be provided for your furnace, at least once per year. You change the oil, antifreeze and have your car greased routinely. Your HVAC system is no different it also requires routine maintenance. Neglect in some cases, may prove hazardous to your family’s health or even deadly. A neglected gas furnace can potentially leak deadly carbon monoxide gases into your home. An annual tune-up includes an inspection that can prevent needless risks to your family.

The Filter

Change the filter every month unless otherwise specified by the manufacturer. Use the type filter recommended, don’t assume a filter with better filtration will work because it will fit. An improper filter may place strain upon the HVAC system and cause damage. Follow the manufacturer’s recommendation for a filter.

The Blower

It is a common occurrence for blowers with cage housing to have debris get caught up in it. An annual furnace tune-up will properly clean the blower. A proper clean not only allows the blower to work more efficiently but also safely. Dirt and debris are removed for greater efficiency but also to prevent excess heat buildup in the motor area. An amp-draw test may be performed on the blower motor and compared to the specification if required. Wiring will be inspected for wear, damage or corrosion.

The Motor

The care provided to the motor will depend upon the motor specifics. Those motors which can be lubricated should receive oil about once per year with a special type of oil created just for this type of motor. Requiring only a few drops it will help the motor to last for many years. Dirt and debris will be removed to prevent overheating.


The ventilation system is checked for blockage and/or leakage. This includes the outside termination (exhaust) and the connections at and internal to the furnace.

Combustion Gases and/or Coils

In a gas furnace, combustion gases must be analyzed to ensure that they meet the unit’s specifications.

Heat Exchanger and Burners

In a gas furnace the heat exchanger and burners are inspected for rust and corrosion. Extensive wear can result in potentially deadly carbon monoxide being released into the home. Burners are also inspected for proper ignition, burner flame and flame sensor.

In an electric furnace the heating coils are inspected for wear, damage and corrosion.


If your furnace is part of a cooling system the drainage is inspected for blockage and/or leakage, including the hoses internal to the furnace. The condensate drain and trap are cleaned and water replaced in the trap.

Static air pressure tests, gas pressure testing and temperature rise checks are performed as required.
