Overview

Air ducts deliver heated or cooled air from the HVAC unit to every room. Proper maintenance can improve air quality, reduce energy bills, and help find leaks that waste energy.

Five essential maintenance tips

1. Seal duct leaks

Duct leaks are a leading cause of wasted energy in homes. Loose or damaged joints can let air escape, increase energy costs, create temperature inconsistencies, and reduce air quality.

Schedule an HVAC inspection at least once a year. A technician can test for leaks, assess duct integrity, and use a camera to check for hidden damage.

2. Keep vents and ducts unobstructed

Blocked vents can cause uneven temperatures. Furniture, rugs, and décor can restrict airflow and strain the HVAC blower fan. This can lower efficiency and shorten the blower’s lifespan.

Clear obstructions around vents to improve airflow and system performance.

3. Clean ducts regularly

Dirty ducts can hurt indoor air quality. The EPA reports that indoor air can be two to five times more polluted than outdoor air, often because of dust, debris, and mold buildup in ducts.

Schedule professional air duct cleaning at least once a year. Technicians use specialized tools with negative pressure to remove debris.

4. Clean or replace vent covers

Dirty vent covers can hinder airflow and reduce indoor air quality. Remove covers, soak them in soapy water, and scrub them with a microfiber cloth to remove dust and debris.

5. Replace your air filter

Changing the air filter helps maintain air quality and HVAC efficiency. Check the system model number for the manufacturer’s recommended filter type. For optimal performance, replace the filter monthly, especially during peak heating or cooling seasons.
