I would recommend a ductless heater/air conditioner. These are highly efficient units that don't require standard ducting, just a condensation line to the outside. Daiken and LG both make units that are very good and have an energy efficiency rating of 17 SEER. They are heat pumps, but small and easier installation than traditional models. They have good air filters in them which are easy to change or clean.
