This is IMO the only way to go. Just make sure they size the unit (BTUs) properly. To big is as bad as too small.

A Mitsubishi split system air-source heat pump, Indoor Unit #MSZ-GE15NA was installed in our 12 x 30 indoor lanai. Our lanai has large sliding windows with screens. Ventilation is great when we want it and dehumidifier, heat and AC are available also. The indoor unit is installed near the ceiling of one of the walls and is approximately 12 x 30... very small and very quiet. Because we installed it on an outside wall, we did not require a pump to move the condensation to the outside.
