To determine the right size, consult an Orlando AC repair and installation contractor like Westbrook Service Corporation. We have access to a calculation method that can help you choose a size. Another important consideration in central air conditioning units is a rating called the SEER rating. These letters stand for Seasonal Energy Efficiency Ratio. New air conditioners are required to have a rating of 13. A unit that was installed over twenty years ago probably has a rating of only 7 or 8. This is because technology has improved the energy efficiency.
