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 so important to search for a system that offers superior comfort in your Elmhurst home while still remaining energy efficient. Greater energy efficiency means your system is working well while using less energy. Whether you are considering a replacement air conditioner or furnace or thinking to upgrade your current equipment to be more energy efficient, there are some ratings to know that will help you during the procedure. So what exactly do those energy efficiency ratings indicate? SEER (used to measure cooling efficiency) SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating reflects the efficiency of your unit at different temperatures, in other words, seasonally in Elmhurst. A greater SEER rating denotes a higher energy efficiency, which will turn into lower utility bills. The Department of Energy requires a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for hotter, southern states. If your home has an older unit with a lower SEER-rating, you could see drastic 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 keeps track of the percentage of heat produced for every dollar of fuel expended. You can think of 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 operates to measure the heating efficiency of heat pumps. It is the SEER rating for winter as it only measures your unit’s heating productivity. Like the others, the higher the number, the more energy efficient the heat pump.
