Hi Guys. I want to buy an AC for commercial purpose around 220 sq.ft . I have seen compressor online catalog for kirloskar and Tecumseh which got EER of 3.2 which is pretty good for reciprocating compressor. Inclined on Reciprocating compressor than rotary for much better cooling under high ambient temperature. Robust unit with simple electronics and good part support is the main criteria. I have narrowed down following brands Napoleon, Totaline, Cruise . Please share your experience with the above brands. I couldnt able to spot split AC with reciprocating compressor yet in website
