A Quick Guide to Cleaning Your Gas Wall Furnace – See this site.

Owning a gas wall furnace requires you to learn how to clean it to maintain its efficiency. It’s important to note that a clean furnace not only prevents the burning of extra fuel but also produces a cleaner and fresher heated air. A typical wall heater functions by sending cold air through the filter. The air is then heated before it’s sent inside the house via a series of ducts. See this site for more info. The heated air can carry any built-up of dirt that is in the furnace.


While it may sound daunting at first, cleaning your wall furnace is an easy task to perform. You’ll only need a few tools for the trade. Here are the things you’ll need:


  • A screwdriver
  • A vacuum
  • A new filter
  • A damp, lint-free cloth
  • Some dry rags


It’s essential to clean your furnace at least once a year – one to two months before the cold season arrives. Keep in mind that the air ducts should be checked by professionals at least twice a month to avoid potential mould and mildew problems. If the filter looks clogged with dirt, it should be replaced with a new one. Also, consider cleaning your filter regularly.


Step 1: Opening the Furnace

Turn off the gas supply for safety purposes. You can also cut off the power supply from the main circuit breaker for extra caution. Open the service panel. It will involve simply popping it open, but most of the time you’ll need a screwdriver. Wipe all the surfaces with a dry rag. Use a vacuum cleaner for areas you can’t reach.


Step 2: Clean the Filters

Locate the filter – generally, it’s found in front of the blower. It’s usually a square-shaped mesh with a plastic or metal frame that’s used to keep the air clean. Remove the filter by sliding or lifting it by hand.


Step 3: Clean the Blower

The next step in cleaning your gas wall furnace is to clean the blower. Wipe it with a dry rag. If the fan blades can be removed, take them out and wipe them clean using a damp, lint-free cloth. Eliminate any dirt or debris on the base of the furnace using a vacuum cleaner. Check for any flaws or defects during the process.


Step 4: Finishing Up

Replace the service panel. Before turning the furnace back on, make sure you clean the outside of your furnace and its surrounding areas. Use a damp, lint-free cloth and vacuum to clean the outdoor areas.



At any time, should you still doubt your skills, you can always hire a professional to have your furnace checked and serviced. For your convenience, you can hire the same company to do your annual checks.


Once you’ve completed every single step, you can now turn on your newly-cleaned gas wall furnace and enjoy its improved performance. See this site for more info. For more home cleaning tips and tricks, subscribe to our newsletter.
