If you want to be able to depend on your furnace during the cold months of winter, then it is vital that you clean it on a regular basis. Unfortunately, if you've never had to clean a furnace before, you may have no idea where to start. Here are a few tips that will help you clean your furnace.
Before you start cleaning your furnace, you must ensure your safety first. To do this, you want to locate the thermostat as well as the power outlet, which feeds the furnace. Locate the off switch to turn off the thermostat. If the thermostat is analog, the off switch will likely be located along the outside edge of the thermostat. On the other hand, if the thermostat is digital, the off switch will likely be located adjacent to the rest of the controls. If you can't find an off switch at all, just turn the temperature to the lowest setting possible.
As an extra precaution, you should remove the fuse and switch off the circuit breaker, which you will find in the electric box of your home. Alternatively, you could just unplug the power source of the furnace.
When cleaning a furnace, you should start with the exterior. Use a duster to remove dust, cobwebs, and dirt from the outputs of the furnace. By removing this residue from the outputs, you won't have to deal with the burning odor that is associated with a furnace firing up after a long period of dormancy. The outputs of a furnace can become extremely hot. When this occurs, any residue on the outputs also become hot, leading to a burning smell.
Once you've cleaned the exterior of the furnace, you can then focus on cleaning the interior. Use a vacuum to clean the furnace's interior. Typically, you will find parts like the main blower and the system control module in the interior of a furnace. When vacuuming the interior of a furnace, be careful not to bump any components. If any of the components become bent, a short circuit may occur. When it comes to the air filters, you can either vacuum them or replace them.
As you can see, cleaning a furnace is not as difficult as it may seem. In order to keep your furnace in good working order, it is vital that you clean it on a regular basis, especially before using it in the cold winter months.
