The new Mitsubishi ductless systems now achieve up to 30.5 SEER!!
These new systems can sense when people are in the space being conditioned. This allows them to be set up to change the temperature when no one is in the room. A great application for this would be a FROG that is only occupied part time. The air conditioner would set back the temperature when no one is in the room….saving additional money. The unit can also be setup to direct air flow towards or around people in the room for additional comfort.
This is a great new product with efficiency that is almost impossible to beat. They qualify for a $300 SCE&G rebate whether installed in a current house or as new construction!
