What to expect at a furnace inspection
Whether you are scheduling furnace maintenance to maximize efficiency, catch small issues before they develop into large and costly repairs, or to help prevent a mid-season failure you should expect the following:
- Heat exchanger(s) Examination. Inspecting for cracks and separations are necessary to ensure that carbon monoxide will not leak into your home.
- Inspecting furnace flue. If the flue pipe is obstructed, rusted, or soft to the touch, harmful gases are not being properly removed from the home.
- Thermostat Inspection. Checking correct calibration and a secure connection from the furnace to the thermostat will make sure that the furnace runs all season. If your thermostat has batteries these should be changed regularly as well.
- Inspecting the fan control to ensure efficient, accurate heating.
- Cleaning and checking the blower. Dirt build up will affect air flow and system balance.
- Lubrications of the furnace motor parts. Keeping the motor properly lubricated saves electricity, reduces friction, and prevents premature failure.
- Changing or cleaning furnace filter. A dirty filter can starve the furnace of air and reduce energy efficiency.
- Checking system safety controls. Verifying that the system will properly shut itself down if parts are malfunctioning is important in preventing possible fires.
- Testing system start-up and shut-down.
- Inspecting electrical connections. Checking that connections are tight and that the correct voltage is being sent helps to keep the furnace from overheating.
- Testing gas pressure. The right amount of gas pressure ensures that the correct amount of fuel is reaching the burners.
- Checking combustion air.
- Examining the thermocouple.
- Testing and cleaning the burner. Making sure that the burners are clean so that you have nice even flames increases efficiency.
