SEER guide & savings calculator
What is SEER?
SEER stands for Seasonal Energy Efficiency Ratio: cooling output during a typical cooling season divided by electrical energy input. A higher rating indicates greater rated efficiency.
Your home matters
The size of your home, insulation and ductwork affect the system you need. Regular maintenance, clean filters and a programmable thermostat can help support efficient operation. Ask about AC replacement or call (704) 879-3644.
Compare estimated cooling costs
Use the same seasonal cooling hours for both systems. These are estimates for comparison, not a promised bill or savings guarantee.
For the same cooling demand, estimated electricity use changes in proportion to current SEER ÷ new SEER. Enter annual cooling electricity use, not your entire household bill.
Compare ratings measured using the same standard. Actual use varies with weather, equipment sizing, ductwork and your home. This comparison is not a prediction of your bill.
