The furnace is one of the more important devices in your home during the winter time, but there are some homeowners that have an extremely limited understanding of them. As a result, these homeowners may be unable to address a couple of the more routine issues that can arise with these heating systems. Once you have an understanding of these common concerns, handling routine furnace problems will likely be a far easier task for you to do. 

How Can You Tell If It Is Time to Change Your Furnace's Air Filter?

One of the most routine tasks that you will need to perform on your furnace is changing the air filter. The air filter is necessary to prevent the interior of the furnace from becoming clogged by airborne debris, and this part of the furnace can become extremely dirty. 

To determine whether or not it is time to change the air filter, you should remove it from the furnace and hold it up to a light. If you are able to see through the filter, then it can be placed back into the furnace. However, if the layer of dust on this filter is too thick for you to see through, then you will need to replace the filter with a new one. 

Why Do You Need to Have the Flue Cleaned?

Furnaces can produce a variety of harmful gases that must be vented out of the home. This is what the flue is designed to do, but you will need to have this part of the furnace professionally cleaned every few years to prevent it from becoming clogged. It is possible for unburnt residue from the furnace to be pulled into the flue, and it can create a thick coating along the walls. Eventually, this can constrict the flow of air, which can cause dangerous gases to back up into the home. 

When the flue is professionally cleaned, a contractor will use a special tool that resembles a wire brush on a long pole to vigorously scrub the interior of the flue. Additionally, they may apply a coating onto the interior of the flue that is designed to help slow the accumulation of residue and soot on the interior of the flue. 

Knowing what is needed to keep a furnace working in good condition is important information for every homeowner. Being aware of when you should change your furnace's air filter and the need for cleaning the flue will make it easier for you to keep your furnace free of problems.
