We are an authorized Weatherking by Rheem distributor. The WeatherKing line is personally my favorite product line in the market. Their shroud on the outdoor unit is designed to protect the coil and compressor in the outdoor unit. How so? 1) the durability of the casing; and, 2) the downward facing louvers. Both of these ensure the outdoor elements and human error do not penetrate the internal components of the unit.
As far as internal components goes, WeatherKing by Rheem comes with a Copeland Scroll compressor; which is the industry leader in HVAC compressors. Additionally, WeatherKing by Rheem comes with a 10 year manufactures warranty when registered online.
