Efficiency Ratings

The Seasonal Energy Efficiency Ratio (SEER) is an energy efficiency rating for air conditioners. The higher the SEER, the better the energy performance, the more you save.

Annualized Fuel Utilization Efficiency (AFUE) is a measure of your furnace’s heating efficiency. The higher the AFUE percentage, the more efficient the furnace.

Customize Your Home

Select the base SEER in which to compare your desired energy efficiency rating. SEER is an energy efficiency rating for air conditioners. The higher the SEER, the better the energy performance.

Select the base AFUE in which to compare your desired energy efficiency rating. AFUE is a measurement of the efficiency with which a furnace turns fuel into usable heat. The higher the AFUE, the more efficient the furnace.

Ccf, which stands for “100 cubic feet”, is the unit used to measure natural gas volume. Your utility company charges a set rate for every cubic foot of natural gas your home uses. The rate you’re paying per Ccf can be found on your electric bill.

A Kilowatt Hour (kWh) is a measure of energy consumption. It is the standard unit that your utility company uses for billing purposes. The rate you’re paying per kWh can be found on your electric bill.

Data

Air conditioner calculations are based on every $100 spent to cool a home using a 3-ton, 10-SEER unit. The criteria base for furnaces is a 60% AFUE unit, with a 50,000-Btuh heating load. Fuel rates and heating hours are factored into the calculation upon selection of a state or region. If a state is not selected, the calculator defaults to the US national average for fuel and electricity consumption. Actual costs and savings will vary depending on weather conditions, usage, location and local utility rates. This information is intended as an example for comparison purposes only.
