What energy efficiency ratings mean and why they're important

January 10, 2017

The cost to heat and cool your home adds up to more than half of your utility bills. That’s why it’s so important to search for a system that offers superior comfort in your Ellsworth home while still ensuring energy efficient. Higher energy efficiency means your system is doing more while using less energy. Whether you are thinking about a replacement air conditioner or furnace or looking to upgrade your existing equipment to be more energy efficient, there are some ratings to know 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 competence of your unit at different temperatures, in other words, seasonally in Ellsworth. A higher SEER rating denotes a larger energy efficiency, which will turn into smaller utility bills. The Department of Energy requires a minimum 13 SEER-rating for chillier states in the north and a 14 SEER-rating minimum for warmer, southern states. If your home has an mature unit with a lower SEER-rating, you could see drastic 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 measures the percentage of heat created for every dollar of fuel used. You can think of it as the MPG on your car. The higher the AFUE-rating, the lower your energy costs. If your furnace has a AFUE rating of 80, that signifies that 80% of the heat produced is consumed 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 effectiveness of heat pumps. It is the SEER rating for the colder months as it only keeps track of your unit’s heating productivity. Similarly, the greater the number, the greater energy efficient the heat pump.
