That’s why it’s crucial to find a system that delivers superior comfort in your Mount Pleasant home while still remaining energy efficient. Better energy efficiency means your system is doing more while using less energy. Whether you are looking into a replacement air conditioner or furnace or thinking 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 competence of your unit at different temperatures, meaning, seasonally in Mount Pleasant. A higher SEER rating signifies a higher energy efficiency, which will convert into less expensive utility bills. The Department of Energy requires 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 mature 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 measures the percentage of heat produced for every dollar of fuel consumed. You can consider 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 generated is consumed to heat the home, while 20% of the heat is lost through venting.
HSPF stands for the Heating Seasonal Performance Factor and works to determine the heating productivity of heat pumps. It is the SEER rating for the colder months as it only determines your unit’s heating productivity. Like the others, the larger the number, the more energy efficient the heat pump.
