Cleaning a gas furnace
Want to save some money from your gas furnace maintenance? Then you should try and clean it by yourself. Keeping it clean will make it work more efficient. Here’s how you can do it.
First of all you will need to shut the system off. For extra safety you can shut off the gas valve. If you do this you will also turn off the pilot light. After you have cleaned the furnace you will need to manually relight it. More modern systems have electronic features that will automatically relight it.
Now remove the panels. Use a vacuum cleaner to clean the dust, dirt and cobwebs. Be careful not to damage any parts in the cleaning process. Next, locate the filters and see if they are dirty and need to be replaced. If they are gray or brownish, then they should be removed and replaced with new ones. See the direction of the flow and the size of the filter. It must fit the same.
Some furnaces have washable filters, meaning that they can be reused several times. They are usually made from plastic or aluminum frames. To clean the dirt, spray water through the filter. Check for rust in the interior of the furnace. If you find any, then you should call a professional to have a better look at the gas furnace. Damaged parts by corrosion may be a sign for carbon monoxide leaks.
After you have thoroughly cleaned the furnace, put the panel back on and turn it back on. Set the thermostat and see if the furnace works properly.
