Here on the South Shore, May and June of 2024 have been relatively cool. As you patiently wait for the summer heat, ensuring your air conditioner (AC) operates at peak efficiency is important for both your home comfort and your energy savings. With temperatures predicted to reach the high 80s soon and humidity levels likely to rise, here are some tips to maximize your AC’s performance during a heat wave.
Regular Maintenance is Key
One of the best ways to keep your AC running efficiently is through regular maintenance. Schedule an annual check-up with an HVAC professional to inspect and clean the unit. This includes checking the refrigerant levels, cleaning the coils, and ensuring the blower components are in good condition. Regular maintenance can prevent breakdowns during the hottest days and improve your AC’s efficiency by up to 15% (Weather.gov).
Optimize Thermostat Settings
Set your thermostat to the highest comfortable temperature. The Department of Energy suggests setting your thermostat to 78°F when you are home and higher when you are away. Each degree you raise the thermostat can save you about 3% on your cooling bill (Weather.gov). Consider investing in a programmable thermostat to automate these settings and avoid wasting energy.
Keep Heat-Producing Appliances Off
During the hottest parts of the day, avoid using heat-generating appliances like ovens, stoves, and even computers. These appliances add extra heat to your home, making your AC work harder to maintain a comfortable temperature. Try cooking meals during cooler times of the day or use a microwave instead.
Shade Your Outdoor Unit
If your outdoor AC unit is in direct sunlight, it can work harder than necessary. Planting trees or shrubs to provide shade for your unit can increase its efficiency by up to 10%. Just ensure that there is adequate clearance around the unit for proper airflow and maintenance access (Weather.gov).
Utilize Window Coverings
Keep blinds or curtains closed during the day to block out the sun’s heat. This simple step can reduce the indoor temperature by up to 20°F and help your AC work more efficiently. Consider using blackout curtains for the best results (Weather.gov).
Change the Air Filters
Clogged or dirty air filters can significantly reduce your AC’s efficiency by restricting airflow. During high usage periods, such as a heat wave, it’s suggested to check and replace your air filters every month. Clean filters allow your AC to cool your home more effectively and can lower your energy consumption by 5-15% (Weather.gov).
Use Ceiling Fans to Your Advantage
Ceiling fans can help distribute cool air more evenly throughout your home. By using ceiling fans in conjunction with your AC, you can raise the thermostat setting by about 4°F without reducing comfort. Remember to turn off fans when you leave the room, as they cool people, not spaces (Weather.gov).
Use Ventilation Strategically
During cooler evenings and nights, turn off your AC and use natural ventilation by opening windows and doors. This can cool your home naturally and give your AC a break. Make sure to close them before the day heats up to keep the cool air inside.
Check Your Insulation
Ensure that your home is well-sealed and insulated to keep the cool air inside. Check for and seal any leaks around windows, doors, and ductwork. Proper insulation to your attic and walls can also prevent heat from entering your home, making it easier for your AC to maintain a cool temperature (Weather.gov).
Upgrade to an Energy-Efficient Model
If your AC unit is 15-20 years old, consider upgrading to a newer, more energy-efficient model. Modern units can be up to 50% more efficient than older models. Look for units with a high Seasonal Energy Efficiency Ratio (SEER) rating; the higher the rating, the more efficient the unit (Weather.gov).
By following these tips, you can keep your home comfortable during the summer heat waves while optimizing your air conditioner’s performance and reducing energy costs. Regular maintenance, smart usage, and some strategic adjustments can make a significant difference in your comfort and energy bills.
