The XL19i air conditioning system has a SEER rating of up to 19.5. The Comfort-R™ removes up to 24 gallons of moisture a day, says the company. Designed in order to cut down on service time, the WeatherGuard II top can be removed rapidly, and only two screws need to be unfastened to remove the service panel, the company states. The Spine Fin woven coil helps to reduce cleaning and provides heat transfer effectiveness. The dual Climatuff® compressors offer two-stage cooling and, when matched with the company's variable-speed indoor unit, greater humidity control, states the manufacturer. The system has a 10-year limited warranty on the compressor, outdoor coil, and internal functional parts.
