What is a Good Energy Efficiency Rating for an Air Conditioner in Desert Shores, NV?

Are you on the lookout for a new air conditioning unit? If so, you’ve probably come across labels and stickers with energy efficiency ratings on them. These ratings can be confusing to some of us but they are very important. They provide insight into how much energy an air conditioner uses, how much it might cost you, and what its environmental impact might be. Hal Mechanical would like to help shed some light on these energy ratings and hopefully help you choose the best air conditioner unit.

SEER Rating: Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio or (SEER) is a measure used primarily in North America to gauge the energy efficiency of air conditioning units and heat pumps. SEER is calculated by taking the total cooling output during a typical cooling season and dividing it by the total electric energy input during the same period. The higher the SEER rating, the more energy-efficient the unit is. As of 2021, the U.S. Department of Energy requires a minimum SEER rating of 13 for air conditioners in most states. However, some of the most efficient units on the market have SEER ratings above 20.

EER Rating: Energy Efficiency Ratio

The Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level, usually 95°F. It’s calculated by taking the total cooling capacity in BTU per hour and dividing it by the power input in watts at a given temperature. The EER rating provides a snapshot of your air conditioner’s efficiency during peak usage times. A higher EER means greater efficiency, where a lower EER will have more energy costs and environmental impact.

COP: Coefficient of Performance

The Coefficient of Performance (COP) measures the efficiency of a cooling or heating system by comparing the energy provided to the energy consumed. Essentially, COP tells us how much useful heating or cooling the system provides per unit of energy consumed. The higher the COP, the more efficient the system is. A COP of 3, for example, means that the system provides 3 units of heating or cooling for each unit of energy consumed.

HSPF: Heating Seasonal Performance Factor

While SEER, EER, and COP mostly focus on cooling efficiency, the Heating Seasonal Performance Factor (HSPF) measures the efficiency of the heating function of heat pumps. It’s calculated by dividing the total heat output by the total energy consumed over the same period. A higher HSPF means the system is more energy-efficient. As of 2021, the U.S. Department of Energy requires a minimum HSPF rating of 7.7 for all new heat pumps.

Why Energy Ratings Matter?

Understanding these ratings is important for a number of different reasons. Here are some of the reasons why you should know and understand energy ratings.
• Energy Savings – Energy efficient models may have a higher upfront cost, but they use less energy, reducing your monthly utility bills and resulting in major savings over time.
• Environmental Impact – Energy efficient units not only save you money but also help to reduce the overall demand for energy, resulting in fewer greenhouse gas emissions.
• Improved Indoor Comfort – High efficiency models often come with advanced features like variable speed motors that help maintain more consistent temperatures and humidity levels.
• Potential Rebates – In some areas, purchasing an energy efficient model could qualify you for rebates from your utility company or government tax credits.
