If you have shopped for a new air conditioner, you have seen SEER ratings everywhere. Understanding what they mean helps you choose a system that balances upfront cost with long-term savings.
What SEER Measures
SEER stands for Seasonal Energy Efficiency Ratio. It is calculated by dividing the cooling output of a system over a typical season by the energy it uses. The higher the SEER, the less electricity the system consumes to deliver the same cooling. Think of it like miles per gallon for your air conditioner.
SEER vs. SEER2
As of 2023, the industry moved to SEER2, which uses updated testing conditions that better reflect real-world installations. SEER2 numbers run slightly lower than the old SEER figures for the same equipment, so when comparing systems, make sure you are comparing the same standard.
How It Affects Your Bills
Upgrading from an older 10 SEER system to a modern 16 SEER unit can cut cooling energy use by roughly a third. Over a hot New Jersey summer, that difference adds up on your monthly electric bill. The higher the SEER, the greater the savings, though the price of the equipment also rises.
Finding the Right Balance
The most efficient system is not always the best value. For most homes, a unit in the 16 to 18 SEER2 range offers a strong balance of efficiency and affordability. Very high SEER systems make the most sense for homeowners who run their AC heavily or plan to stay in their home for many years.
A professional load calculation ensures the system is sized correctly, because even a high-SEER unit wastes energy if it is too large or too small for your home.
