In the late 1980s, the US Department of Energy devised the Energy Star Program as a way to set energy standards on home and industrial appliances and reduce energy consumption across the nation. They adopted the SEER rating system as a standard for measuring the energy efficiency of major appliances like air conditioning units and refrigerators. SEER stands for seasonal energy efficiency ratio. As of 2015, the SEER rating in the Southeast is 14, but there are units on the market today with ratings that go up to 25. Obviously, the higher the rating, the more you save on energy costs, but a high rating also means a higher price tag. In the 19-22 range, you’ll find a wide selection of energy-efficient models that are more affordable.
When it comes to choosing a size, the same concept applies: bigger isn’t necessarily better. A bigger unit will use more energy and cycle on and off more frequently throughout the day as the temperature inside your home changes. A unit that's too small will run continuously trying to meet your demands. Eventually, it will overheat or malfunction, leaving you without comfort controls. HVAC units are measured in tons. To calculate the tonnage you need, first, measure the square footage of your living space. Multiply that number by 30, then divide your answer by 12,000. If you live in the Southwest, this final number is the approximate size you need. If you live outside of the Southwest, subtract 1 from your final answer. Round your answer to the nearest half ton to get the size you need. For more help selecting the unit for your home contact your local HVAC company in Suwanee, GA.
