What energy efficiency ratings mean and why they’re important

The cost to heat and cool your home totals more than half of your utility bills. That’s why it’s crucial to find a system that offers excellent comfort in your Greencastle home while still remaining energy efficient. Higher energy efficiency means your system is operating well while using less energy. Whether you are considering a replacement air conditioner or furnace or looking to upgrade your existing equipment to be more energy efficient, there are some ratings to be aware of that will help you during the process. 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 Greencastle. A higher SEER rating denotes a larger energy efficiency, which will turn into smaller 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 mature unit with a lower SEER-rating, you could see radical 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 think of it as the MPG on your car. The higher 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 lost through venting.

HSPF stands for the Heating Seasonal Performance Factor and works to determine the heating efficiency of heat pumps. It is the SEER rating for winter as it only determines your unit’s heating effectiveness. Like the others, the greater the number, the extra energy efficient the heat pump.
