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 imperative to look for a system that offers superior comfort in your Anchorage home while still ensuring 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 existing equipment to be more energy efficient, there are some ratings to be aware of that will help you during the procedure. So what exactly do those energy efficiency ratings mean?

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 Anchorage. A larger SEER rating denotes a greater energy efficiency, which will convert into lower utility bills. The Department of Energy expects 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 upgrade.

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 produced for every dollar of fuel consumed. You can look at 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 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 measure the heating effectiveness of heat pumps. It is the SEER rating for the colder months as it only determines your unit’s heating efficiency. Again, the larger the number, the more energy efficient the heat pump.
