What is a Seasonal Energy Efficiency Ratio Rating?
If you’re looking to buy a new air conditioning system for your home or office, you may have noticed many A/C models are given a Seasonal Energy Efficiency Ratio rating (SEER). For those who want to save money and consume less energy, the SEER rating will help you determine which unit is the most efficient.
How Is SEER Determined?
An air conditioning unit’s efficiency is determined by its total cooling capacity during standard annual usage divided by its total energy consumption for that same time period. Essentially, the higher the SEER rating, the less energy is needed for the A/C unit to operate. The formula for determining SEER is:
Capacity (Btuh) x Hours x Electricity Rate = Operating cost
What is a Good SEER Rating?
Today, the SEER ratings of air conditioners can vary from 13 to 24. SEER ratings of 13 and 14 are considered average efficiency, while units with ratings of 15 SEER and above are seen as high efficiency.
Why is SEER Important?
Though costs could be higher to install an air conditioning unit with a high SEER rating, the overall savings on your energy bill is worth the investment. Most units with a rating of at least 14 qualify for the Energy Star label, and many of these appliances can help homeowners earn tax credits, conserve energy and are better for the environment.
