Knowing when to DIY Preparing your HVAC system for peak seasons is important, which is why you should have a trained GC Heating and Cooling technician, service your system at least once a year. These regular checkups can help to prevent larger issues and keep your system running smoothly year round.
DIY furnace maintenance
Start by looking at your furnace. Is there any black soot around the furnace? If so, Schedule an appointment now!. Next, turn on the thermostat and set it above room temperature so the furnace comes on. Look at the flames in the burner. You want to see a steady, blue flame. If you see yellow or orange flicking, Schedule an appointment now! to determine whether anything other than natural gas is burning. Also listen for questionable noises or vibrations while the furnace is on, and smell for any gas leaks.
TURN YOUR FURNACE AND GAS OFF
After the visual inspection, turn the thermostat off and flip the power switch off on the furnace (or turn off the breaker if the furnace doesn’t have a switch). It’s very important that if you are performing any kind of gas furnace maintenance that you turn off the gas line. The gas line should have shut off valve near your gas meter.
CLEAN AND DUST
Once the furnace has cooled, open the furnace door. Use a vacuum with a long nozzle to clean out and the furnace base. For areas your vacuum can’t reach, such as the fan blades, use a damp cloth to wipe away dust.
CHECK YOUR FAN BELT
If your blower has a fan belt, inspect it for cracks or fraying. You can also check the tension by pushing down in the center of the belt. If it deflates by more than half an inch, it will need to be tightened. A trained GC technician can assist you with tightening or replacing the fan belt.
FINISH YOUR MAINTENANCE AND CHANGE THE FILTER
Replace the furnace panels and turn the furnace power and gas pack on. You may need to relight the pilot light. The final item on our gas furnace maintenance checklist is to inspect and change the filter. Your filter may need to be changed as often as once a month during heating season. Be sure to check it often to keep your air clean and your family breathing easy.
