A well-maintained air conditioner runs more efficiently, lasts longer, and keeps your energy bills lower. Here are 10 essential maintenance tips.
1. Clean or Replace Filters Monthly
Dirty filters restrict airflow and reduce efficiency by up to 15%. Check filters monthly and replace or clean them as needed.
2. Keep the Outdoor Unit Clear
Maintain at least 2 feet of clearance around your outdoor unit. Remove leaves, debris, and trim nearby plants.
3. Check Refrigerant Levels
Low refrigerant means your AC works harder and costs more to run. Have a professional check levels annually.
4. Clean the Coils
Both evaporator and condenser coils collect dirt over time. Clean coils ensure efficient heat transfer.
5. Inspect Ductwork
Leaky ducts can waste 20-30% of cooled air. Have ducts inspected and sealed if necessary.
6. Check Thermostat Settings
Upgrade to a programmable thermostat to save up to 10% on cooling costs.
7. Clear Drain Lines
Clogged drain lines can cause water damage and humidity problems. Flush with diluted bleach quarterly.
8. Listen for Unusual Sounds
Grinding, squealing, or rattling sounds indicate problems. Address them early to avoid costly repairs.
9. Schedule Annual Professional Maintenance
Professional tune-ups catch problems early and keep your warranty valid.
