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 so important to search for a system that delivers quality comfort in your Columbia 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 considering to upgrade your existing 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 considers the competence of your unit at different temperatures, in other words, seasonally in Columbia. A greater SEER rating signifies a greater energy efficiency, which will turn into smaller utility bills. The Department of Energy requires a minimum 13 SEER-rating for chillier 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 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 measures the percentage of heat created for every dollar of fuel consumed. You can look at it as the MPG on your car. The greater the AFUE-rating, the less your energy costs. If your furnace has a AFUE rating of 80, that denotes that 80% of the heat created is used to heat the home, while 20% of the heat is misplaced through venting.

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