Comparable Models by Armstrong
Model Comparison by Price - Armstrong 4SCU20LX versus Armstrong 4SCU16LE
The 4SCU16LE is a single-stage unit with a lower SEER of 16. It has a compressor blanket to reduce noise but it does not have the swept-wing fan design. Both units use MHT™ technology and have filter driers to keep out contaminants. Painted panels ensure that the unit is durable and weather resistant, and rounded corners make it more aesthetically pleasing. Both units have a high pressure switch to avoid unsafe pressures in the refrigerant.
Model Comparison by Features - Armstrong 4SCU20LX versus Armstrong 4SCU16LS
The 4SCU16LS is a good model that has some of the same features. It has a lower SEER rating of 16 and is a two-stage rather than a variable speed compressor. However, both units have Comfort Sync technology that lets you adjust your temperature with an app and get alerts about maintenance. The 4SCU20LX however has a swept-fan blade design to be more efficient and reduce noise. Both units are covered by the same warranty.
