What energy efficiency ratings mean and why they're important

January 10, 2017

The cost to heat and cool your home totals more than half of your utility bills. That’s why it’s crucial to search for a system that delivers quality comfort in your Opelika home while still being energy efficient. Higher energy efficiency means your system is operating well while using less energy. Whether you are considering a replacement air conditioner or furnace or considering to upgrade your current equipment to be more energy efficient, there are some ratings to be aware of that will help you during the process. So what exactly do those energy efficiency ratings represent?

SEER (used to measure cooling efficiency)
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating takes into consideration the effectiveness of your unit at different temperatures, meaning, seasonally in Opelika. A larger SEER rating denotes a higher energy efficiency, which will turn into lower utility bills. The Department of Energy expects a minimum 13 SEER-rating for colder states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an mature unit with a lower SEER-rating, you could see radical energy savings after an improvement.

AFUE or HSPF (used to measure heating efficiency: gas or electric)
AFUE stands for Annualized Fuel Utilization Efficiency ratio and it keeps track of the percentage of heat generated for every dollar of fuel expended. You can think of it as the MPG on your car. The larger the AFUE-rating, the lower your energy costs. If your furnace has a AFUE rating of 80, that signifies that 80% of the heat created is exhausted to heat the home, while 20% of the heat is misplaced through venting.

HSPF stands for the Heating Seasonal Performance Factor and works to measure the heating productivity of heat pumps. It is the SEER rating for winter as it only determines your unit’s heating productivity. Again, the higher the number, the greater energy efficient the heat pump.
