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 look for a system that offers superior comfort in your Branchville home while still remaining energy efficient. Better energy efficiency means your system is operating well while using less energy. Whether you are considering a replacement air conditioner or furnace or thinking to upgrade your present equipment to be more energy efficient, there are some ratings to look out for that will help you during the process. So what exactly do those energy efficiency ratings indicate?

SEER (used to measure cooling efficiency)
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating considers the effectiveness of your unit at different temperatures, meaning, seasonally in Branchville. A greater SEER rating indicates a greater energy efficiency, which will convert into smaller utility bills. The Department of Energy expects 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 older unit with a lower SEER-rating, you could see extreme energy savings after an modern system.

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 expended. You can think of it as the MPG on your car. The greater the AFUE-rating, the smaller your energy costs. If your furnace has a AFUE rating of 80, that denotes that 80% of the heat produced is consumed to heat the home, while 20% of the heat is lost through venting.

HSPF stands for the Heating Seasonal Performance Factor and operates to determine the heating productivity of heat pumps. It is the SEER rating for the winter season as it only keeps track of your unit’s heating effectiveness. Similarly, the higher the number, the greater energy efficient the heat pump.
