With a cooling capacity of 24,500 BTU (2 tons), it can handle medium to larger rooms comfortably. Its SEER rating of 17 is quite good, meaning it uses electricity efficiently to keep your energy bills reasonable.

Installation requires professional help and the package comes with necessary parts and a 16-foot line set pre-charged with refrigerant. The design is sleek and unobtrusive, fitting well in homes or small businesses.

Warranty coverage is strong, with five years on parts and compressor. If you need to cool or heat multiple zones independently or want a higher efficiency rating, this might not be the best fit.
