Why do I need to change my furnace filter???

 

There are quite a few times while speaking with customers, friends, family, or just people at the store, I will come across someone who either doesn’t know what the reason is for changing their furnace filter or doesn’t even know that there is a furnace filter that needs to be changed. YIKES!!!

As a home owner, you can spend upwards of $10 000 in some instances to have a heating, ventilation and air conditioning system installed in your home (as an initial investment). To change just one aspect of that down the line, can cost upwards of $5000. Now, why is it that after making such a large investment, people rarely take care of it? When it comes to a new car, which sometimes can cost about the same amount, car owners are diligent in getting it repaired regularly. Most people very rarely ever see, hear, or realize that their HVAC system is there or running because it is tucked away in the back corner of their home.

Just like a car needs an oil change, or your water jug needs a new water filter, your furnace needs to have the filter changed on a regular basis. If you have pets, smoke, live in a dusty area, or have a not so spotless home, and even if none of those pertain to you, YOU NEED TO CHANGE YOUR FURNACE FILTER! The filter in your furnace or air conditioner is not JUST for keeping the air in your home cleaner, although giving your family the best clean air to breathe should be more than enough of a reason to change it. Having a clean furnace filter helps prevent dust from being circulated through your home. It removes allergens from the air that can be detrimental to your families health, and it also protects your furnace from breaking down which is its main purpose.

When a furnace has a dirty filter in it, the fan motor will begin to over heat because there is not enough air flowing through it to cool the motor down. Once the fan motor over heats, eventually it will need replacing. Also what can happen is the furnace itself can over heat causing part of it to crack which can allow fumes into your home and potentially cause death. Now if breathing clean air, or having to pay for expensive replacement parts isn’t cause enough to make sure that you change your furnace filter regularly, maybe knowing that it has the potential (even though very slim chance) to cause death will be enough.

I don’t mean to sound drastic or over the top but there are so many reasons to install a new furnace filter regularly that it doesn’t make sense why someone would invest so much into something and not do as much as possible to protect that investment. I know how much people hate hearing how much a new furnace, fan motor or air conditioner will cost, so hopefully before it comes to that dreaded conversation, a small precautionary maintenance is all that it takes to prevent it.
