Air filters trap dust, allergens, and debris—but if neglected, they block airflow and reduce HVAC efficiency. Coastal conditions near Charleston and Summerville, like pollen and humidity, mean filters should be changed at least every 1–3 months. A clean filter improves comfort, lowers energy bills, and helps your system last longer.
At Legacy Home Helpers, our HVAC-certified team serves Goose Creek, Charleston, and Summerville to ensure your filters are properly selected and maintained.
Step‑by‑Step Guide
Turn off your HVAC – via thermostat or breaker.
Locate the filter slot – often near return vent or air handler.
Remove and inspect the filter – look for dirt and check the correct size.
Install a new filter – ensure airflow arrow points correctly.
Write the install date – helps track replacements.
Run system briefly – check airflow and fit.
Tips for Peak Coastal Conditions
Avoid cardboard-backed filters prone to moisture warp.
Use MERV-8 to MERV-11 rated filters for allergen filtering.
Replace monthly if allergies or pets are factors.
