What Should I Know About A/C Efficiency Ratings?

Shopping for the right air conditioning and mechanical equipment can be a confusing process.  How do you know which system is best suited for your building?  How can I tell if my A/C is energy efficient?  Here is what you need to know about A/C efficiency ratings and why Jet Industries Inc. represents only the top quality and efficient equipment:
  • Jet Industries Inc. Carrier Air Conditioners are rated for efficiency using the “seasonal energy efficiency ratios” or SEER. The higher the SEER number the more efficient the unit is and the better job it does of cooling your home for with less energy. Less energy used means fewer dollars spent on energy bills which is of course a good thing.
  • Like most energy appliances air conditioners have made great strides over the last several years. In the late 1980s, the average SEER rating for an air conditioner was around 6.0. In 1992 the U.S. Department of Energy (DOE) who regulates the minimum SEER rating of new air conditioners in the United States mandated that all units sold must have a 10 SEER rating or higher. Today the minimum level allowed to be sold is 13 SEER and manufacturers offer high-efficiency units ranging from 16 SEER all the way to 20 SEER!
  • It is important to note that there is a difference between the size (or capacity) and its efficiency rating. A 3-ton air conditioner (36,000 BTU/hr) which is 8 SEER will cool at roughly the same rate as a 3-ton air conditioner with a 12 SEER rate. When we talk about efficiency we are really talking about the amount of energy used to create the 36,000 BTU/hr. To put it another way, SEER is similar to the MPG rating your car has while the size of the AC unit is similar to the amount of horsepower that your car has.
