How to Determine Efficiency
The efficiency of an air conditioner is measured by the Energy Efficiency Ratio (EER), which is the ratio of the cooling capacity (in BTUs per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner. The Department of Energy sets minimum efficiency standards for air conditioners, and the ones meeting or exceeding these standards are labeled with the ENERGY STAR® certification.
Types of Energy Efficient Air Conditioners
There are two types of energy efficient air conditioners:
1. Central Air Conditioners
Central air conditioners are designed to cool the entire house by distributing cool air through ducts. These units have a Seasonal Energy Efficiency Ratio (SEER) rating, which indicates the cooling output over a typical cooling season divided by the energy usage during that time. Higher SEER ratings mean greater energy efficiency.
2. Room Air Conditioners
Room air conditioners are portable or window units that are used to cool a single room or small space. They are rated using the EER system mentioned earlier. Look for units with higher EER ratings for increased energy efficiency.
Benefits of Energy Efficient Air Conditioners
Investing in an energy efficient air conditioner offers numerous benefits:
- Lower energy consumption: These units consume less energy, resulting in reduced electricity bills.
- Environmental friendliness: By using less energy, energy efficient air conditioners reduce greenhouse gas emissions and help protect the environment.
- Improved comfort: Energy efficient air conditioners can provide a consistent and comfortable temperature, ensuring a pleasant indoor environment.
- Longer lifespan: Energy efficient units are often built with high-quality components, leading to increased durability and longevity.
- Higher resale value: Having an energy efficient air conditioner installed in your home can increase its value when it comes time to sell.
Tips for Choosing an Energy Efficient Air Conditioner
When selecting an energy efficient air conditioner, consider the following:
- Look for the ENERGY STAR® label: This certification ensures that the unit meets or exceeds the minimum energy efficiency standards set by the Department of Energy.
- Consider the size: Choose an air conditioner that is suitable for the size of the space you need to cool. An oversized unit may waste energy, while an undersized unit may struggle to effectively cool the area.
- Check the EER or SEER rating: Higher ratings indicate better efficiency.
- Consider additional features: Look for features like programmable thermostats, sleep modes, and energy-saving settings to maximize energy efficiency.
- Maintain regular maintenance: Proper and regular maintenance ensures optimal efficiency and extends the lifespan of your air conditioning unit.
