What energy efficiency ratings mean and why they’re important01/10/2017The cost to heat and cool your home makes up more than half of your utility bills. That’s why it’s imperative to search for a system that offers excellent comfort in your South Central PA home while still being 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 current 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 represent? SEER (used to measure cooling efficiency) SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating reflects the competence of your unit at different temperatures, or rather, seasonally in South Central PA. A higher SEER rating signifies a larger energy efficiency, which will turn into lower 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 mature unit with a lower SEER-rating, you could see drastic 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 keeps track of the percentage of heat generated for every dollar of fuel used. 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 means that 80% of the heat produced is exhausted to heat the home, while 20% of the heat is misplaced through venting. HSPF stands for the Heating Seasonal Performance Factor and works to determine the heating productivity of heat pumps. It is the SEER rating for the winter season as it only determines your unit’s heating productivity. Again, the larger the number, the more energy efficient the heat pump.
