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 imperative to find a system that delivers excellent comfort in your Wausau home while still ensuring energy efficient. Higher energy efficiency means your system is operating well while using less energy. Whether you are looking into 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 search. 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 competence of your unit at different temperatures, or rather, seasonally in Wausau. A larger SEER rating denotes a higher energy efficiency, which will turn into less expensive utility bills. The Department of Energy requires 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 aged unit with a lower SEER-rating, you could see radical 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 keeps track of the percentage of heat generated for every dollar of fuel consumed. You can think of it as the MPG on your car. The larger the AFUE-rating, the less your energy costs. If your furnace has a AFUE rating of 80, that denotes that 80% of the heat generated 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 effectiveness of heat pumps. It is the SEER rating for winter as it only measures your unit’s heating effectiveness. Again, the greater the number, the greater energy efficient the heat pump.
