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 crucial to search for a system that offers quality comfort in your Brookfield home while still remaining energy efficient. Greater energy efficiency means your system is operating well while using less energy. Whether you are thinking about a replacement air conditioner or furnace or thinking to upgrade your existing equipment to be more energy efficient, there are some ratings to know that will help you during the search. 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 Brookfield. A greater SEER rating indicates a greater energy efficiency, which will convert into smaller utility bills. The Department of Energy demands a minimum 13 SEER-rating for colder states in the north and a 14 SEER-rating minimum for hotter, southern states. If your home has an aged unit with a lower SEER-rating, you could see extreme 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 expended. You can look at 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 created is exhausted to heat the home, while 20% of the heat is wasted through venting.

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