When you are planning on installing a new HVAC system in your home , you may come across acronyms such as SEER and AFUE. SEER ratings are used for air conditioning system, whereas AFUE ratings are used to describe the efficiency of heating systems. SEER stands for Seasonal Energy Efficiency Ratio and AFUE is shorthand for Annual Fuel Utilization Efficiency. The higher the SEER or AFUE rating, the better efficiency you will get from the unit.
