With energy costs always rising, folks in Rusk, Texas, are more concerned than ever about saving money. HVAC air filters may seem like one of those costs you can avoid, but failing to replace them regularly can lead to increased maintenance costs over time. So, how long do HVAC filters last? The answer depends on a number of factors.

Figuring Out When to Change Your HVAC Filter

Air filters, in general, should be replaced every one to three months, but this is a broad suggestion. Factors to consider when asking yourself this question include:

  • The type of air filter
  • Whether you have pets
  • Your home’s indoor air quality
  • Number of family members
  • Local area

Some regions experience more pollution and construction than others, so if you live near a city or high-traffic road, check your filters more frequently. The more people and pets in your home, the more dust and pet dander floating around, so it’s best to err on the side of caution and swap them out monthly.

If your indoor air doesn’t seem as fresh as it used to, or you suffer from allergies, replacing the filters more often can help. Keep in mind, however, that each type of air filter has a set lifespan, so check the manufacturer’s recommendation for how often you should buy a new one.

How to Know When it’s Time for a Change

Some homeowners stick to a set schedule for changing their HVAC air filters. While this is a good rule of thumb, don’t be afraid to inspect the filters to see how quickly they get clogged. You don’t need to change them unless they’re dirty, so changing them prematurely can waste money. To start, set a specific date on the calendar each month and inspect the filter. If it still looks clean, wait another week and check again.
