How To Choose an Energy-Efficient Air Conditioner
- Home Size: The size of your home is one of the most important factors in selecting an energy-efficient air conditioning unit. Larger homes will require a higher tonnage unit, while smaller homes can benefit from a smaller tonnage unit that still offers efficient performance.
- Climate: The climate in your area plays a significant role in how much you’ll rely on your AC. If you live in a region with hot, humid summers, choosing a system with a higher SEER2 or EER2 rating will ensure it can handle the demand while maintaining efficiency.
- Maintenance: Regular maintenance is essential to keeping your system running efficiently. Some models require more frequent servicing, so it’s important to choose a system that fits your ability to schedule maintenance.
- Budget: While energy-efficient air conditioning units can be more expensive upfront, they can offer savings over time through reduced heating and cooling bills. Consider your initial investment in relation to the long-term savings to ensure the unit fits within your budget.

How to Improve the Efficiency of Your A/C
1. Perform Regular Maintenance
- Replace Air Filters: Clogged filters restrict airflow, forcing your AC to work harder, increasing energy costs. Check and replace filters regularly, aiming for every 1-3 months.
- Clean Condenser Unit: A clean outdoor condenser unit allows the AC to cool more efficiently, preventing it from becoming overworked.
- Vacuum Vents: Ensure vents are free of dust and debris to allow for optimal airflow throughout the system.
- Check and Seal Ducts: Leaky ducts can cause significant energy loss. Inspect and seal any leaks to prevent wasted energy.
2. Optimize Your Home Environment
- Ensure Proper Ventilation: To keep your home comfortable, make sure vents are open and not blocked.
- Close Curtains and Blinds: During the hottest parts of the day, close curtains and blinds to block sunlight and reduce heat buildup.
- Use Ceiling Fans: Ceiling fans can help circulate air, making you feel cooler and reducing the need for AC to work as hard.
- Close Off Unused Rooms: To maintain high efficiency, close the door and vents of unused rooms to prevent them from being cooled unnecessarily.
- Use Natural Ventilation: Open windows in the evening or early morning to take advantage of cooler temperatures.
- Limit Heat-Producing Appliances: Avoid using heat-generating appliances like ovens and dryers during peak hours to reduce the load on your AC.
- Plant Trees: Planting trees around your home can provide shade, reduce the heat load on your AC, and help to lower your cooling bills.
