Can you please explain what a "Splitter " is??

We also have a lantana and we are in the process of not only enclosing the lanai with Glass but making it part of our family room by raising the lanai floor and taking out the Sliding glass doors. We had an energy (heat/ac) study done by Munns (as required by County) and they are going to provide heat and air conditioning to the expanded family area (former lanai) by adding a new main line directly from the exchange in the garage and have 3 outlets in the lanai area. Some contractors wanted to simply entend as exisiting main line from your family area into the lanai area but Munns said that was NOT the way to go.

Sounds like you are getting a separate ac unit (is it a Mr Slim by mitsibusti (sp)?? Did you check into adding to your exisitng AC/Heat? The Mr Slim unit is best to be installed directly over your exisiting sliding glass doors and the compressor can really be placed anywhere it will fit. The longer the line you will lose some efficiency but it should not be that much. The biggest thing is to make certain your lanai area is well insulated ...whenyou enclsoed teh lanai this was most likely not an issue if you did not at that time add heat/ac.
