What Homeowners Need to Know About Air Filter Maintenance
At Bellaire Air Conditioning, one of the most common questions we hear is: “How often should AC filters be changed?” And it’s a good one—because staying on top of your air filter changes plays a major role in your HVAC system’s performance, your energy bills, and even your indoor air quality.
A dirty air filter can cause airflow issues, strain your system, and increase utility costs. Regular filter changes are one of the easiest and most affordable ways to extend the life of your air conditioning unit, especially during Houston’s long cooling season.
How Often Should You Really Change Your AC Filter?
There’s no one-size-fits-all answer, but here’s a breakdown of the most common timelines:
- Standard fiberglass filters: Every 30 days
- Pleated filters: Every 60–90 days
- Homes with pets or allergies: Every 30–45 days
- Vacation homes or seldom-used systems: Every 6 months
- High-traffic households: Monthly
Keep in mind that usage, indoor air quality, and filter type all affect how often you should change it.
If you’re unsure, it’s always safe to check your filter monthly. If it looks dirty—change it.
Signs It’s Time to Replace Your AC Filter
Besides marking your calendar, there are a few signs your filter might be overdue:
- Increased dust in your home
- Higher-than-usual energy bills
- Weak airflow from vents
- More frequent allergy symptoms

If you notice any of these signs, your AC filter might be clogging up your HVAC system. Routine air conditioning maintenance can help prevent these issues.

FAQs
How do I know if my AC air filter needs replacing?
You’ll likely need to replace your AC filter if it looks dirty, clogged, or discolored. Other signs include poor airflow, dust accumulation around your home, or longer system run times. Regularly checking the filter and scheduling routine maintenance can help you stay on top of its condition to avoid system inefficiencies.
How long should an AC filter last?
On average, an AC filter lasts about 30 to 90 days, depending on factors like the type of filter and household conditions. Homes with pets or higher levels of dust may require more frequent filter changes to maintain optimal airflow and air quality.
What happens if you don’t change your AC air filter?
Neglecting to change your AC filter can lead to clogged airflow, causing your system to work harder and use more energy. This not only results in higher utility bills but can also lead to overheating and potential system failure. Regular filter changes are essential for efficient operation and to maintain good indoor air quality.
Does changing AC filter lower bill?
Yes, changing your AC filter regularly can reduce your energy bills. A clean filter allows air to flow freely, preventing your system from overworking and consuming excess energy. It helps your system run more efficiently, which can keep costs down.
Can I clean my AC filter instead of replacing it?
If your AC filter is washable, you can clean it rather than replace it. Just make sure it’s thoroughly cleaned and dried before reinstalling. However, most disposable filters should be replaced, not cleaned. Keeping up with regular filter maintenance ensures your system operates efficiently and improves air quality.
