When to Replace Your AC Filter (Dallas Guide)
Expert advice, maintenance tips, and industry insights to help you get the most from your HVAC system.
Living in Dallas means your AC works hard—especially during those long, hot summers. But many homeowners don't realize how much of a difference a simple filter change can make. Your air filter isn't just about clean air—it's also about the efficiency, longevity, and reliability of your HVAC system.
So… how often should you really replace your AC filter in Dallas? Let's break it down.
📆 General Rule: Every 1 to 3 Months
Most homes in Dallas should replace their air filters every 1 to 3 months. But that range depends on a few key factors:
- 🐾 Do you have pets? Pet hair and dander clog filters faster. If you have dogs or cats, aim for every month.
- 🧼 Are you sensitive to allergies or dust? North Texas can be tough on allergy sufferers—especially during spring. For clean air and fewer sniffles, stick with a 30–45 day replacement schedule.
- 👨👩👧👦 How many people live in the house? More people = more dust and activity. Bigger families might need to replace filters more often than a single-person household.
- 🏠 Do you live in a new home or one under renovation? New homes and remodeling projects kick up a surprising amount of dust. You may need to change filters every 2–3 weeks during this time.
💡 Dallas-Specific Tip
Dallas summers = nonstop AC use. That means your system pulls more air through the filter daily—and clogs it faster. In July and August, we recommend checking your filter every 3–4 weeks, especially if your system runs 24/7.
🔧 Signs Your Filter Needs Replacing
Not sure when you last swapped your filter? Look out for these signs:
- Weak airflow from vents
- Unusual dust buildup on furniture
- AC system seems to run longer than usual
- Higher energy bills (yes, dirty filters make your system work harder)
🛠️ What Type of Filter Should You Use?
In Dallas homes, we typically recommend:
- MERV 8–11 for general use
- MERV 13 if you have pets or allergies
- Avoid washable filters unless you clean them every 2 weeks
✅ The Bottom Line
Replacing your AC filter isn't just maintenance—it's prevention. In a city like Dallas, where summers are brutal and AC is essential, changing your filter regularly helps:
- Lower energy bills
- Improve indoor air quality
- Extend the life of your HVAC system
