What is the seer rating and tonnage of an ac unit?

The SEER (Seasonal Energy Efficiency Ratio) rating measures the cooling efficiency of an air conditioning unit over a typical cooling season, with higher values indicating better efficiency and lower energy costs. Tonnage refers to the cooling capacity of the AC unit, with one ton equating to the ability to cool 12,000 BTUs (British Thermal Units) per hour. For optimal performance and efficiency, it's essential to choose an AC unit with a suitable SEER rating and tonnage for the specific space being cooled.
