We have found this great article about furnace cleaning listed below on the net and think it made good sense to discuss it with you over here.
DIY Furnace Troubleshooting & Repairs
If your home is heated with a forced-air heating system, a furnace or a heat pump is the heater at the heart of it. Here we look at how to handle furnace problems from a furnace working poorly to a heater not working at all. For heat pump problems, see Heat Pump Troubleshooting & Repairs.Though forced-air furnaces are normally quite reliable, they can break down. To avoid break downs, it pays to know how to maintain your furnace and fix it when something goes wrong.
Inevitably, a furnace stops working when you need it most. Consequently, fixing becomes urgent very quickly.
The following instructions will help you do the fixing—or at least figure out what needs to be fixed. With a little do-it-yourself experience and the proper guidance, you can troubleshoot and repair a variety of furnace problems yourself.
General Furnace Maintenance
If possible, also slide out the fan unit, clean each fan blade with a toothbrush, and then vacuum with a brush attachment on a vacuum cleaner.While you’re at it, look for oil ports on the motor, normally located near the motor shaft. If the motor has these, apply two to three drops of non-detergent motor oil into each port (you may have to remove a cover plate to do this). Though most contemporary motors don’t require lubrication, motors with oil ports should be lubricated once a year. For more about maintenance, see Maintenance Checklist for Central Heating Systems.
Gas Leak
If you suspect a furnace gas leak, deal with this immediately!First, if you smell natural gas in your home or near the furnace, do not light any matches or turn off or on any switches. If the gas odor is strong, immediately evacuate your house, leaving the door open.
Hand and wrench turning off a home's gas supply valve.
To shut off the gas supply to your home, turn the valve until it rests perpendicular to the supply pipe (here the gas is on).
Turn off the gas supply valve, typically located by your gas meter on the gas inlet pipe.
Turn off the gas by rotating the valve one quarter turn with an adjustable wrench.
When the gas is off, the valve’s oblong stem points perpendicular to the inlet pipe. Then call your gas utility or the fire department from a remote location. Do not return to your home until you know it is safe.
Heating Repair And Regular Maintenance Tips
You can maintain a furnace system a number of different ways. Chances are good that the system will be running all day long in the winter. furnace systems normally run more than needed, due to incorrect settings. When troubleshooting and optimizingthe heating segment of your heating system, there are several areas to consider.Replace The Air Filter
This is what you usually hear people speaking about most often, but so few people take the advice and do anything about it. If there is a obstruction, you either run the risk of not circulating heat adequately or possibly starting a fire.When the air conditioner filter becomes dirty air cannot flow through as well which means the unit must work overtime and could also mean a likelihood of fire. If the system is not circulating heat effectively, it will be working overtime. The fire issue is self-explanatory. In both situations it is not suitable for peace of mind or your funds.Test The Blower
Check the blower blades and clean them up. A dirty fan will work overtime to blow air around and of course use higher energy to preserve the thermostat level you choose it at. Meaning that the system is over taxed and costing extra money to run.Fire Damper Function
Next, look at the fire damper to make sure it is running acceptably. This will make sure that the fir risk is lowered and the system works more effectively.The Flex Duct
It is feasible that your ducts became damaged over the years for a variety of reasons. If there are blockades or the duct has collapsed somewhere the heating system will think the correct temp has been achieved, which can be wrong. When this happens the system works harder to do its job but is going to be incapable to reach the desired tempurature.Band Insulation
It is easyto miss the insulation, but is probably the most common reason for a system malfunctioning. Take take time to focus on the insulation between the duct work and the outside to make sure it has not worked itself loose. When this happens furnace works more than desired while attempting to reach the best temperature.Ductwork Needs To Be Connected
Make be certain the ductwork is connected everywhere to all pieces. These detachments can cause space in the ventilation and cause a loss of hot air in your home, since it will be getting out through the holes.Return Air Inlets
Make certain that that return air intakes are free of dust and debris so air can flow easliy.Zone Dampers
Examine the zone dampers to check if they are in the correct spot. Throughout the year we could change the positioning of the damper for many reasons (i.e. getting in a tight space or arranging for storage). For a properly functioning system, check to see that the dampers are actually in the right spot.If this is a tad too much to handle on your own, we propose you hire a local plumbing business licensed for furnace and heating repair.
