What energy efficiency ratings mean and why they’re important01/10/2017The cost to heat and cool your home adds up to more than half of your utility bills. That’s why it’s crucial to look for a system that offers quality comfort in your Great Falls home while still remaining energy efficient. Greater energy efficiency means your system is working well while using less energy. Whether you are thinking about a replacement air conditioner or furnace or looking to upgrade your existing equipment to be more energy efficient, there are some ratings to know that will help you during the search. 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 considers the effectiveness of your unit at different temperatures, in other words, seasonally in Great Falls. A greater SEER rating indicates a greater energy efficiency, which will convert into lower utility bills. The Department of Energy demands 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 aged 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 finds the percentage of heat generated for every dollar of fuel consumed. You can consider 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 means that 80% of the heat created is exhausted 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 productivity. Like the others, the greater the number, the more energy efficient the heat pump.
