Ask ten websites how often to change your filter and you’ll get “every 90 days.” That advice wasn’t written for Craighead County. Between spring pollen pouring off Crowley’s Ridge, May cottonwood fluff, and dust from surrounding farmland, Jonesboro filters clog faster than average.
The Honest Schedule
- Basic 1-inch fiberglass filters: every 30 days, no exceptions in summer.
- Pleated 1-inch filters: 30–60 days — check monthly.
- 4–5-inch media filters: 4–6 months.
- With pets or allergies: cut every interval in half.
Why It Matters More Here
A clogged filter is the number-one cause of frozen coils, weak airflow, and burned-out blower motors we repair in Jonesboro. It also forces your system to run longer for the same cooling — which shows up directly on your Jonesboro City Water & Light bill.
A Word on MERV Ratings
Higher isn’t always better. A MERV-13 filter in a system designed for MERV-8 can strangle airflow as badly as a dirty filter. If you want better filtration, ask us — sometimes the answer is a media cabinet, not a denser filter.
