Keeping a gas furnace in respectable working order is not all that tough if you follow a regular maintenance routine every few months with the filters and at least once a year with the gas components. A good idea is to keep a protection timetable you can refer to every few months for things like the roof, electrical, air conditioning and of course the furnace. We've planned out a few ideas for furnace maintenance you can track below.
1. The Filtration System
The filters are the first line of defence and an critical part of the system. The filters are generally cheap and easy to swap unless you have an electrostatic filter or something similar. If you make use of the low-cost everyday filters like most of us you may want to exchange it every three months to help the furnace work better.
2. Furnace Cleanliness
When cleaning the furnace summer is best since it's turned off. You can take a vacuum and a stiff brush to deal with the dirt and other crap. It's likely there can be oxidation if you haven't done this before. A wire brush will handle the rust and your house vacuum should be fine for removing the debris.
3. Tension Belts
Over time the tension belt will relax and you'll almost certainly hear it rattling It's really easy to tighten up or replace if that has occurred.
4. Motor Lubrication
The furnace motor needs oiling annually. A few drops of light oil will keep it running smoothly.
5. The Pilot Light
The pilot light has to be on for the furnace to operate. If you can not see the flame at the base, then chances are good the pilot light has died. It will burn a deep blue color, but if it isn't burning that color then it maybe time for a tune up. If the pilot light is off and you can't get it lit, phone a plumbing contractor or natural gas technician.
6. Checking Your Thermostat
Do a little test to see if the thermostat is functioning as it should be. The old varieties use mercury in the switch. To test those types make sure that the room is quiet and remove the cover. Moving the lever up and down makes the mercury slide from side to side, and if you see the spark or hear the furnace come on then it's working. With digital thermostats you'll see what's going on by reading the display.
Check to see that the vents are not plugged. Most vents are custom designed but all have the identical function. If you have never had your vents examined then you may need to cut a hole in the vent channel to check inside and poke around. But only do so if you have the equipment to seal the hole. If your aeration has never been checked and five years has passed, then it's time to have them looked at. Dirty air vents have a lot of offensive material and may be the cause of colds and flu. The collection of particles, squirrel droppings, dead stuff, lost toys and a lot of other stuff that get lost through the vents need to be removed every couple of years, mostly for health factors.
8. Gas Leakage
Your furnace is a gas appliance and is potentially dangerous. If you can smell rotten eggs that might be mercaptan, which smells bad and is there for safety factors. If you do happen to smell that terrible oil refinery odor then there's a natural gas leak in the home, so get out and call for help later. Never call from inside the home! Don't smoke or light a match, do not activate anything electric or use some ignition source. Doing so may ignite the fumes. Once outside, go to the closest telephone and call 911 for help.
