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 look for a system that offers superior comfort in your Columbia home while still being energy efficient. Better energy efficiency means your system is working 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 look out for that will help you during the procedure. 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 effectiveness of your unit at different temperatures, or rather, seasonally in Columbia. A larger SEER rating indicates a greater energy efficiency, which will translate into lower 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 humid, 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 finds 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 lower your energy costs. If your furnace has a AFUE rating of 80, that signifies 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 determines your unit’s heating productivity. Like the others, the higher the number, the more energy efficient the heat pump.
