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 so important to search for a system that delivers quality comfort in your Mount Pleasant home while still remaining energy efficient. Greater energy efficiency means your system is working well while using less energy. Whether you are looking into a replacement air conditioner or furnace or considering 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 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 Mount Pleasant. A higher SEER rating denotes 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 mature unit with a lower SEER-rating, you could see drastic energy savings after an modern system. 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 created for every dollar of fuel expended. You can look at 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 works to keep track of the heating efficiency of heat pumps. It is the SEER rating for the colder months as it only determines your unit’s heating effectiveness. Like the others, the higher the number, the greater energy efficient the heat pump.
