Prevent Heating Repair With Regular Furnace Cleaning

Before you splash out money on expensive heating repair, when was the last time you cleaned your furnace? If you're like most homeowners, the answer is probably never. Maintaining a furnace, whether gas, electric, or oil can be intimidating, but can also save you money on heating repair and improve overall performance. So what are you waiting for? Put on some rubber gloves, grab a flashlight, and start your next spring-cleaning routine with your furnace.

Machines don't work so well when clogged up with dirt, grime and dust. Particles and debris will build up over time, jamming components and decreasing efficiency (which in turn will increase your power bills). When cleaning your furnace, you'll want to focus on three areas for maximum results: the filter, blower, and motor. Before beginning any heating repair though, be sure to shut off the furnace and gas supply when applicable. You don't want any nasty shocks. It's better to perform these tasks before you begin using your heater rather than during peak season (although you should do quick filter cleans during periods of heavy use).

Start cleaning by removing surface dirt and vacuuming in and around the furnace. In fact, the entire room should be given a good vacuum as this is the dirt that will eventually wide up inside your heater if left for too long. Next you'll want to clean or replace the filter. This is usually marked, or just look below the duct and blower for a box that will contain it. Filters can be either disposable (cardboard frame) or permanent which will look much sturdier. Buy a replacement disposable from the hardware store or clean the permanent, replace, and you're finished. Be sure to insert it correctly to avoid damaging the system.

Once you've finished with the filter, it's time to move on to the blower. There should be a metal panel over the filter, which can be removed with a screwdriver. Depending on the type of furnace, you may see a fan or it may be hidden by squirrel cage. Unscrew the cage and carefully remove the components, being sure to mark or take photos of how everything is positioned (it must be replaced exactly). Using some soapy water, gently clean away any dirt and dust from the blower wheel. A toothbrush or other soft bristled brush is useful for getting into small spaces without causing damage. Clean the housing and any other vacuum belts, pulleys, and motor components. Use a vacuum as a final touch up to suck out any last remaining bits of grime. It is important to be gentle and exercise caution, as some of the metal parts are very delicate. Bending them out of place can cause damage to the entire furnace.

Yearly cleanings with occasional filter checks in between should keep your furnace running better year round. Ductwork should also be cleaned every few years or more for homeowners who suffer from severe allergies. If you're still too intimidated to clean your furnace, you should have a professional heating repair technician perform the job regularly.
