Along with that annual inspection, customers should change furnace filters according to the manufacturer's instructions.
While checking a furnace, the contractor should make a visual inspection of all vents, heat exchangers and motors. Dominion notes that a thorough inspection should include:
- Lubricating the blower bearings and blower motor as recommended by the manufacturer;
- Visually inspecting all vents, the heat exchanger and filters;
- Checking the pilot light if the furnace has one;
- Cleaning and checking the flame sensor on higher-efficiency furnaces with electronic ignition;
- Cleaning the main burners;
- Clearing the furnace area of any dust or combustible materials;
- Cleaning dust from the blower compartment;
- Testing the thermostat to ensure the heating system works as it should;
- Checking the safety components on the heating equipment, such as limit controls and pilot safety and pressure switches;
- Checking the flue to ensure it is clean and open. Any fuel that does not burn completely can create harmful levels of carbon monoxide. The gas can collect in a home if a fuel-burning appliance is not working or venting properly;
Customers should make sure an annual inspection includes all other gas appliances, such as water heaters, gas logs, vent-free heaters, ranges and clothes dryers.
