What energy efficiency ratings mean and why they're important

January 10, 2017

The cost to heat and cool your home makes up more than half of your utility bills. That’s why it’s crucial to look for a system that offers excellent comfort in your Shelby home while still being 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 considering to upgrade your current 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 efficiency of your unit at different temperatures, meaning, seasonally in Shelby. A larger SEER rating denotes a greater energy efficiency, which will translate into smaller utility bills. The Department of Energy demands a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for humid, southern states. If your home has an older 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 generated for every dollar of fuel expended. You can look at it as the MPG on your car. The greater 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 consumed to heat the home, while 20% of the heat is wasted through venting.

HSPF stands for the Heating Seasonal Performance Factor and is used to keep track of the heating efficiency of heat pumps. It is the SEER rating for the colder months as it only determines your unit’s heating efficiency. Again, the greater the number, the more energy efficient the heat pump.
