Air It Up SEER Calculator: Estimate Your Air Conditioner’s Efficiency

KNOW THE MATH TO SAVE

In 2006, the average retail price for electricity was 10.40¢ per Kilowatt hour. By May 2018, that price increased to 13.15¢ per Kilowatt hour. That’s a 26.44% increase in your electricity costs! With rates rising, how can you stay cool and comfortable in your home and spend less on utility costs? Your answer may rest with new, energy-efficient HVAC equipment and its Seasonal Energy Efficiency Ratio or SEER.

Air conditioners and heat pumps are assigned a SEER rating related to the unit’s energy efficiency and performance for cooling. But what exactly is SEER, and why should it matter to you?

Understanding SEER: What It Means for Your HVAC System

The Seasonal Energy Efficiency Ratio (SEER) is a critical metric that measures the efficiency of air conditioning systems. It represents the cooling output during a typical cooling season divided by the total electric energy input during the same period. A higher SEER rating indicates a more efficient system, which can lead to significant energy savings over time.

For instance, an air conditioner with a SEER rating of 16 can save you up to 30% more energy compared to a model with a SEER rating of 13. This efficiency not only reduces your utility bills but also lessens your environmental footprint, making it an essential consideration when selecting or upgrading your HVAC system.

Benefits of High SEER Ratings

Investing in HVAC systems with high SEER ratings offers numerous benefits beyond just cost savings. Higher efficiency systems generally provide better cooling performance and maintain more consistent indoor temperatures, enhancing overall comfort during hot months.

Moreover, many utility companies offer rebates or incentives for homeowners who install energy-efficient systems, further offsetting the initial investment. The long-term savings on electricity bills combined with these incentives make high SEER-rated units a financially smart choice for homeowners.

How to Calculate Your SEER

Calculating the SEER of your air conditioning system is straightforward and can be done using a simple formula. You need to know the total cooling output in BTUs (British Thermal Units) and the total energy consumption in watt-hours during the cooling season.

To find your SEER, divide the total BTUs by the total watt-hours. For example, if your system produces 48,000 BTUs and consumes 3,000 watt-hours, your SEER would be 16. This method helps you evaluate your current system's efficiency and compare it with new models.

Factors Affecting Your HVAC Efficiency

Several factors can influence the efficiency of your HVAC system, including the age of the unit, maintenance practices, and the quality of installation. Older systems often have lower SEER ratings and may require more frequent repairs, leading to increased energy consumption.

Regular maintenance, such as changing filters and cleaning coils, is crucial to ensure optimal performance. Additionally, a professional installation can help maximize your system's efficiency, ensuring it operates at the manufacturer’s intended SEER rating.
