If you’re considering a new HVAC system for your Highland Park, Illinois, home, you should look carefully at the energy efficiency ratings for your new installation. Choosing a system with better ratings will help you recoup some of the cost of the installation in the form of energy savings.

Seasonal Energy Efficiency Ratio (SEER)

Your SEER rating tells you how efficient a cooling system is over the course of an entire year. The is the ratio of the electrical input to the cooling output. This rating is based on an average temperature of 82 degrees, so you shouldn’t expect the same efficiency at higher temperatures. Systems with higher SEER ratings outperform those with lower numbers here, so look for an upgrade that will enhance your energy savings.

Energy Efficiency Ratio (EER)

The EER is very similar to the SEER, but it’s calculated differently. This number is based on testing at higher temperatures around 95 degrees or more. The EER rating also takes humidity into account. Look at both the SEER and EER.

Heating Seasonal Performance Factor (HSPF)

Used on the heating function for heat pumps, this rating lets you know the system’s heating efficiency as it’s averaged over the course of an entire season. The number is the ratio of heat generated to electricity consumed. Single package unit heat pumps must have an HSPF of at least 8, while split systems need a minimum of 8.2.

Annual Fuel Utilization Efficiency (AFUE)

This rating applies to furnaces and determines the percentage of heat that’s produced per dollar of fuel that’s used. The higher this number is, the less you’ll spend on heating fuel.
