3 Reasons Why Replacing Your Air Filter Is So Important

Switching out or cleaning an air filter can oftentimes feel like such a small job that most homeowners assume it’s okay to skip. But what many don’t know, however, is that air filters have a direct impact on their home’s comfort, their utility costs, and even their health and well-being. 


On that note, here are three key reasons why the HVAC experts at Astoria Heating & Cooling, a Fern Park AC company, say you need to remember to replace your air filters:


1. It Drastically Improves Your Indoor Air Quality

The primary responsibility of an HVAC filter is to trap particles before they circulate throughout your home. Clean filters make excellent barriers, stopping everything from pollen to pet dander from getting into your airways. However, once debris clogs a filter, it’s nowhere near as efficient, and it’ll force those pollutants back out into your home, where you eventually breathe them in. Replacing your filters regularly ensures your home remains a clean and healthy living space.


2. It Lowers Your Energy Bills

A lesser-known issue that arises from a dirty air filter is energy waste. Caked-on dirt and dust restrict airflow, forcing your system to work much harder to cool your home. That, in turn, means the unit will require more energy to operate, and you’ll have to pay more than you bargained for on your monthly bills as a result. Changing your filter at least once every two to three months is one of the easiest ways to save on your energy bills.


3. It Keeps Your HVAC System Healthy

The increased workload that comes from having to push cool air through a dirty filter leads to faster wear and tear on your components, which can cause mechanical issues in the short term. The longer you go without switching filters, the higher your chances of it causing your system to give out prematurely. Protect your investment by being consistent with your replacement schedule and calling a Fern Park AC company at the first sign of trouble.
