The ARC-14SH has the capacity to cool rooms up to five hundred square feet.
The 36 by 19 by 16 inch size and eighty pound weight make this Whynter model fairly large, but the casters make it portable enough to be moved from one room to another without too much effort. The unit comes with a window kit, but extenders would be needed if the installation window is more than 36 inches wide.
The auto-drain feature means that most of the accumulated moisture will evaporate naturally, and this will keep this maintenance aspect to a minimum. You may need to drain the unit more frequently when the weather is particularly humid or if you use the ac as a dehumidifier. The warning light feature will alert you when the water reservoir level becomes too full.
The dual-hose system of the ARC-14SH provides greater efficiency. One hose cools the compressor as it draws in air from the outside, and the second hose keeps the room cool as it vents heat out and away from the system.
The 11.2 energy efficiency rating is worth noting, and the programmable timer lets you adjust the temperature in anticipation of temperature changes during the day. Three fan speeds and a handy remote control are part of the package as well.
The pre-filter is easy to access and wash, and this reduces dust and various air-born particles. Smoke and other odors are removed by the activated carbon filter, and replacing the filter every three months will help your portable ac unit run smoothly.
