Change your dirty air filter. Here’s why!

furnaceFilterWith the winter season coming up and everyone getting ready for Christmas, often times the little things get forgotten. One of them being changing your air filer every month. It may seem like a very insignificant home maintenance routine, but one that most homeowners don’t realize plays a big part in maintaining their home comfort. Energy Star recommends you change your air filter every month, especially during the heating season and cooling season and don’t let your filter go unchanged no more than three months. It doesn’t matter if it’s the heating season or cooling season, a dirty air filter can cause a number of damages to your heating and air conditioning system.


Why is it so important to replace your air filter? Here are some benefits if you regularly replace your air filter:

  1. Extends the life of your HVAC system

A dirty air filter is the most common reason why a heating and air conditioning system breaks down. If you don’t regularly change your filter, dirt, dust, and debris accumulate and clog up the filter. Causing it to not allow air to pass through, or worse, the system overheats. With a clogged filter, the motor has to worker harder to get the air through. If you’re lucky, your unit just needs repairs, but worst case scenario, you would have to replace the unit. Just replacing the filter can lengthen the life expectancy of your system.

  1. Keeps energy costs low

When your air filter is clogged, your system works harder to push air through causing it to use more energy. More energy being used to power you’re heating and air conditioning system, causes your energy bill to skyrocket. If you stay consistent with replacing your air filter, you can save 5 to 15 percent on your utility cost.

  1. Improves indoor air quality

Dirty air filters can deteriorate the air quality in your home. If a filter is dirty, everything that passes through it is dirty too as it travels through the air ducts. It pumps dust and allergens all throughout your home where you and your family are breathing in dirty air. Allergens can cause a number of physical symptoms, like headaches, fatigue, cold symptoms and many more. If you have pets, it’s even more important to replace your filter, because pet dander will accumulate in the system and spread throughout the house. It’s easy to prevent deteriorating air quality just by regularly replacing your filter.

  1. Keeps your heating and air conditioning systems clean

Frequently replacing your filter can keep your systems clean. Dirt, dust and debris can clog up your filter can lead to polluting your entire HVAC system. That could mean extra repairs, services and part that you didn’t plan on spending on.


Just by regularly replacing your filter is an easy and inexpensive way to maintain your system and save money. While also extending the life of your system and improving the indoor air quality in your home. If you’re not sure when the last time you replaced your filter, it probably best to replace it as soon as possible to prevent any damage to the system. Don’t know where the air filter is located?
