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 crucial to find a system that provides excellent comfort in your Lexington home while still being energy efficient. Greater energy efficiency means your system is operating well while using less energy. Whether you are considering a replacement air conditioner or furnace or considering to upgrade your present equipment to be more energy efficient, there are some ratings to look out for that will help you during the process. 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 takes into consideration the competence of your unit at different temperatures, or rather, seasonally in Lexington. A higher SEER rating denotes a larger energy efficiency, which will translate into smaller utility bills. The Department of Energy expects a minimum 13 SEER-rating for cooler states in the north and a 14 SEER-rating minimum for warmer, southern states. If your home has an older unit with a lower SEER-rating, you could see extreme 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 produced for every dollar of fuel used. You can look at 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 created is exhausted to heat the home, while 20% of the heat is wasted through venting. HSPF stands for the Heating Seasonal Performance Factor and works to determine the heating effectiveness of heat pumps. It is the SEER rating for the colder months as it only keeps track of your unit’s heating productivity. Similarly, the greater the number, the more energy efficient the heat pump.
