Learn How to Replace or Clean your Furnace Filter
It is important that your heating and cooling system is turned off before you attempt to replace or clean the furnace filter. Locate the service panel of the system and remove the cover with a screwdriver. Sometimes, the cover can be removed by hand too, depending on how it is fastened. The filter will be located near the outtake-intake blower. Check to see how dirty the filter is. If you cannot see through it, it is time for a cleaning or replacement.
Some filters are reusable and will require that you remove them and wash away the dust particles that cling to it. Using an outdoor hose with a sprayer, spray down the filter until it looks clean again and then allow to air dry before putting back in place. Disposable filters can be tossed when they become dirty and replaced with a new, clean one. Once you have replaced the filter, you can turn your heating system back on.
