Oil furnaces are used in heating the house, room or building when the season of cold weather has arrived in your area. This helps the people staying inside avoid getting frozen from the coldness of the surrounding, enabling them to do their daily routine and activities. They do it by letting the flame heat the air with the resulting smoke exiting through a chimney.
This is important part of buildings that are located in places with cold climates since freezing from cold, which is very dangerous, is avoided. Though their constant usage may mean that you need to hire companies offering their oil furnace cleaning PA services. But doing it yourself is possible if you are confident with your abilities and want to save some money.
Be sure to shut off the fuel supply and electrical power before any maintenance is performed and be safe when doing this activity. The switch for electricity is usually located near the burner or on top of cellar stairs while for the fuel is nearby the tank or incoming gas pipe. Take note of their locations in case of fire or leak in the future.
The combustion chamber is where the fuel is mixed with air then ignited to generate heat and also carbon dioxide, water vapor and soot. The buildup of the latter could cause for its walls to corrode so scrape them out with the use of a wire brush. Remove loose materials using industrial shop vacuum then inspect the inside for corrosion or holes before the cover is replaced.
Inspect the flue pipes used for the exhaust to determine if there are holes that can cause leakage of carbon monoxide, particularly near the furnace. You can patch the small holes using foil tape though replacing corroded ones is a must. This is because tall chimneys of old houses have the tendency in sucking too much air and compromises its efficiency.
Oil filters prevent the clogging of small impurities in the burner nozzle that could cause a misfire which shuts the system down. Close the valve first, remove the old filter then replace with a new one while the dirty item is being set aside. You must dispose it according to the local regulations of disposing hazardous waste.
Change the air filter where all the air your family breathes comes through during the winter even if doing so often is inadvisable but at least do not use them over a year. Changing them is something easily done by any homeowner. Check the wear and tension of the blower belt which moves the heated gases from furnace to room vents.
The blower is driven with an electric motor and if the belt is loose, it could slow it down and the efficiency is compromised. If ever the belt would deflect more than a quarter of an inch when firmly pressed then adjust it. This could be done by sliding backward the motor slightly.
Set a combustion analyzer up that calculates efficiency of furnace by measuring the amount of gases in exhaust flue. This ensures the fuel to air ratio is appropriate. Remember to clean the floor vents as well.
