Smart Usage Habits
Simple changes in your daily routine can significantly impact your air conditioning electricity usage.
- Avoid Heat-Generating Activities: Minimize cooking, laundry, and other heat-producing activities during the hottest parts of the day.
- Use Fans: Ceiling fans and portable fans can circulate air and make you feel cooler, allowing you to raise the thermostat temperature.
- Close Doors and Vents: Close doors and vents in rooms you’re not using to concentrate cooling in occupied areas.
- Utilize Natural Ventilation: Open windows and doors during cooler evenings and mornings to ventilate your home and reduce the need for air conditioning.
Consider Upgrading Your Air Conditioner
If your air conditioner is old or inefficient, consider upgrading to a newer, energy-efficient model.
- Energy Star Certification: Look for air conditioners with the Energy Star label. These models meet strict energy efficiency guidelines.
- SEER Rating: The Seasonal Energy Efficiency Ratio (SEER) measures the cooling efficiency of an air conditioner. A higher SEER rating indicates greater energy efficiency. Aim for a SEER rating of 15 or higher.
- Proper Sizing: Ensure your new air conditioner is properly sized for your home. An oversized unit will cycle on and off frequently, wasting energy and reducing comfort. An undersized unit will struggle to cool your home effectively.
The table below compares SEER ratings and potential energy savings:
| SEER Rating | Energy Savings Compared to SEER 10 |
|---|---|
| 13 | 23% |
| 16 | 38% |
| 20+ | 50% or more |
Common Mistakes to Avoid
Many homeowners unknowingly make mistakes that increase their air conditioning electricity consumption. Avoiding these pitfalls is essential.
- Ignoring Maintenance: Neglecting regular maintenance can significantly reduce the efficiency of your air conditioner.
- Setting the Thermostat Too Low: Setting the thermostat too low doesn’t cool your home faster; it simply causes your air conditioner to run longer and consume more energy.
- Blocking Airflow: Obstructions around vents and the outdoor unit can restrict airflow and reduce efficiency.
- Leaving Windows and Doors Open: Allowing outside air to enter your home increases the workload on your air conditioner.
Understanding Government Incentives and Rebates
Many utility companies and government agencies offer incentives and rebates for energy-efficient air conditioners and home improvements. Research available programs in your area to save money on your initial investment. DSIRE is a good website to check for federal, state and local rebates.
