How Often Should You Change a Dirty Air Filter?

Oct 1, 2024

The implications of a clogged and dirty air filter are more significant than one might realize. Have you considered the effects of allowing your HVAC air filters to remain clogged for extended periods? While this issue may seem minor, obstructed air filters can severely impact the quality of your indoor air and overall well-being, leading to various adverse effects. At New Albany Heating & Cooling, we strive to inform Ohio homeowners about the potential risks associated with neglected air filters to prevent serious HVAC-related consequences. 

What makes a dirty air filter concerning? 

  • Deteriorated Indoor Air Quality: A blocked air filter significantly impairs your HVAC system’s ability to reduce airborne pollutants such as dust, pollen, and germs, leading to poor indoor air quality. This issue is particularly worrisome for residents in Ohio, where changing seasons bring a variety of allergens that can exacerbate respiratory conditions like asthma and allergies.  
  • Increased Energy Consumption: When your HVAC system works overtime to push air through a clogged filter, energy consumption rises. Research by the Department of Energy indicates that replacing a dirty, obstructed filter with a clean one can lower your air conditioner’s energy use by 5% to 15%. Given Ohio’s unpredictable weather, it’s crucial to avoid overworking your HVAC system.  
  • Potential System Failure: Neglecting your air filter can have repercussions beyond poor air quality and high energy bills. Failing to replace your air filters can force your HVAC system to operate inefficiently, leading to increased strain and potentially resulting in costly system failures and repairs in the future.  
  • Circulation of Pollutants and Contaminants: A clogged air filter allows harmful pollutants and contaminants to circulate throughout your home, including mold spores, pet dander, and tobacco smoke particles. These substances can trigger a range of health issues, from minor irritations like sore throats to more severe conditions such as respiratory infections.  
  • Dust and Debris Accumulation: It’s a no-brainer that one of the most immediate and harmful effects of a clogged air filter is the accumulation of dust and debris in your home. You’ll likely notice dust building up on surfaces and HVAC vents, compromising your home’s cleanliness and contributing to the inhalation of these particles.  
  • Spread of Germs and Bacteria: A less recognized but equally serious consequence of a congested air filter is the proliferation of germs and bacteria. A dirty filter can become a breeding ground for harmful microbes, which then circulate throughout your home, exacerbating existing respiratory conditions.  
  • Increased Allergy Symptoms: Additionally, if you have allergy symptoms that persist no matter what you do to lessen their negative effects, it may be time to assess your air filter. Look for signs such as sneezing, coughing, and itchy eyes, all of which can be aggravated by substandard indoor air quality.  
  • Unpleasant Odors: An obstructed air filter can lead to unpleasant odors infiltrating your home, ranging from musty to foul, depending on the contaminants trapped within the filter. Staying proactive with air filter maintenance can help prevent such undesirable situations.  

When To Change Your Dirty Air Filters: 

  • Seasonal Shifts – Given Ohio’s significant seasonal variations, it is essential to inspect your air filter at the beginning of each season. This practice ensures that your HVAC system is well-prepared to meet the demands placed on it throughout the year. We generally recommend homeowners replace air filters every 30-90 days, based on usage and lifestyle needs. 
  • Post-renovations – If you frequently engage in home DIY projects, please be aware that after most home renovations, it is advisable to replace your air filter. Construction activities can generate substantial dust and debris, which can quickly clog your filter. 
  • Pet Owners – For pet owners, it is crucial to change air filters more frequently due to the rapid accumulation of pet dander and fur, which can negatively affect your home’s indoor air quality (IAQ). 

Maintaining a clean air filter is vital for the longevity of your HVAC system and for ensuring superior indoor air quality. For homeowners in Ohio, where seasonal changes can significantly influence air quality, regular maintenance is essential. By recognizing the indicators of a blocked air filter and understanding how to address this issue, you can foster a healthy and welcoming home environment.
