Why You Should Change Your Air Filter (And How)

Your central heating and cooling system’s air filter is a critical component that requires regular maintenance. Just as you clean your home and yourself, it is essential to keep your filter clean. By removing pollen and dust particles from the air, your air filter can help prevent sickness and allergies. Additionally, it acts as the first line of defense against bigger objects such as loose insulation that could cause damage or present a fire hazard. However, failing to change your filter regularly can lead to significant issues. Clogged filters are the leading cause of heating and cooling system failure.

When your air filter is dirty, it slows down your entire system, and your blower fan must work much harder than usual to push air. This increased workload draws more energy, leading to higher energy expenses. It also means your living area won’t get all the air it needs or can get, leading to poor indoor comfort. As a result, the thermostat may not even reach your ideal set temperature, causing your system to remain on, ultimately resulting in more money wasted.

Moreover, a dirty air filter can cause your system to freeze up since the heated or cooled air will be trapped in the furnace, heat pump, or air conditioner. This means that you’ll be paying for the same amount of gas or oil usage with no change in indoor temperature.

As material accumulates on the air filter, it can become a breeding ground for moisture, mold, and bacteria. This growth increases the number of allergens and pollutants in your home. If air isn’t circulating properly, particles will settle in your ducts, resulting in a drain on your system’s efficiency and another source of bacteria in your home. In conclusion, changing your air filter regularly is an easy and effective way to save money on energy expenses and stay healthy.

How To Change Your Filter:

To maintain optimal performance, we recommend swapping out your filter every month. Most filters are inexpensive and extremely easy to change without the help of a professional.
Before replacing your filter, check your unit’s documentation to ensure you have the correct size and the minimum efficiency reporting value (MERV) range your furnace requires. Be careful not to select a filter with a MERV rating that is too high, as it can cause your filter to clog prematurely, even if it’s new.
If your filter is located in the ductwork attached to your HVAC system, just slide the old filter out and slide the replacement filter in its place. It’s that simple!
If your filter is located in a return air duct, unhook the latch on the cover grille and remove the filter. Clean the grille with a microfiber cloth, wiping between the slats or using a vacuum with a brush attachment to remove any dust buildup. Then, slide the new filter in place and reattach the cover grille.
Insert a new filter, ensuring the correct furnace filter direction.
Close the cover grille and secure the latch.

Changing your air filter is a quick task to add to your routine. If you replace it regularly, your wallet and lungs will thank you. As always, if you have any other questions or concerns, relax! Just Call Budget!
