9.7
The Energy efficiency rating for the LG 3850 BTU Air Conditioner/Heater unit is 9.7.
It's difficult to compare energy efficiency of stoves, but look at their Energy Star rating.
It is the energy efficiency rating. The higher the no. of stars the less electricity or power is used making the fridge more efficient.
The SEER metric is used to measure a heating and cooling systems performance, which is determined largely by the HVAC equipment operating efficiency. SEER stands for Seasonal Energy Efficiency Rating.
Seasonal Energy Efficiency Rating, For the definition of how it is calculated. Go to Energy Star.com or do a Google search on SEER.

The SEDBUK rating is an energy efficiency rating developed by the UK government and used in the boiler industry. It is used to provide a comparison between different models of boilers and different manufacturers.
Efficiency rating: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G
ENERGY STAR is a U.S. Environmental Protection Agency voluntary program that helps businesses and individuals save money and protect our climate through superior energy efficiency. Appliances, buildings, and climate control systems can earn an Energy Star rating by showing a high degree of energy efficiency.
The factor?
Central air conditioners are rated by manufacturers according to the Seasonal Energy Efficiency Ratio or SEER. The higher the rating the more energy efficient the unit has been determined to be and the greater your energy savings will be. This rating system is governed and regulated by the US Department of Energy.
The efficiency rating is called annual fuel utilization efficiency or afue. For residential systems in the USA, the minimum is 80%. There is no standard for what is considered "high efficiency". The range of efficiencies goes up to about 96% for gas furnaces.
