How does a Higher Seer2 Rating Impact my Energy Bills?

Aug 3, 2026

A higher SEER2 (Seasonal Energy Efficiency Ratio 2) rating directly impacts your energy bills by reducing the amount of electricity required to cool your home. Because SEER2 measures how much cooling output a system provides per watt-hour of electricity consumed, a higher number indicates greater efficiency.

Key ways a higher rating affects your costs include:

  • Lower Monthly Consumption: Systems with higher ratings use less power to maintain comfortable temperatures. For example, a unit rated at 18 SEER2 is approximately 12.5% more efficient than a 16 SEER2 unit.
  • Reduced Seasonal Waste: Higher ratings mean less energy is wasted over the course of the cooling season, which translates to lower demand on your utility meter.
  • Long-Term Savings: While high-efficiency units have a higher upfront cost, the annual energy savings can offset this investment over time. In Colorado Springs, upgrading from a baseline 14 SEER2 unit to an 18 SEER2 unit can result in estimated annual savings of $200 to $350.
  • Peak Performance Efficiency: Units with high ratings often feature advanced technology, such as dual-stage compressors, which help the system maintain efficiency even during the hottest afternoons when electricity demand is at its peak.
