Pros
Pro Ideal for both warm and cold weather
The unit has a heat mode where the thermostat can be adjusted to temperatures between 61 and 77 °F. It operates as a heat pump that basically does reverse air conditioning.
Pro Can handle even large spaces, and quickly
The AC's cooling capacity is a whopping 14 000 BTU, meaning that it can efficiently cool large spaces up to 500 sq. ft. And it can do it rather quickly, if the initial conditions aren’t too drastic.
Pro Can work autonomously
This air conditioner can be pre-programmed to operate without supervision. You can simply set the desired working intervals, during which it will adjust the ambient temperature to match the pre-set one.
Pro Comes with a remote control
This air conditioner comes with a remote control that allows you to configure the unit from a distance.
Pro Very power-efficient
Despite the impressive performance level, this unit doesn’t use much electricity. There is a thermostat that turns the compressor on and off to maintain the desired temperature, and you can schedule a timer for more efficient operation. On top of that, this unit has a dual-hose system, making it more economical and efficient compared to units with only one exhaust hose.
Pro Cleans the air
This AC unit comes equipped with a standard reusable pre-filter that traps dirt, pet hair, and other large particles. Additionally, it has two other filters: an activated carbon filter that removes odors from the air and an antimicrobial air filter that stops mold and mildew growth and keeps the air free of small particles that could be potentially damaging.
Pro Efficient moisture use
The built-in auto-drain feature pulls moisture out of the air and turns it around to cool down the air while exhausting the condensate outside the room. Using moisture this way not only helps more economically (in terms of electricity consumption), but also saves the hassle of draining the unit from condensate and reduces air humidity.
Pro Restarts automatically after a power outage
In the event of a power outage, the unit will resume working using its last programmed settings, once the power is back.
Cons
Con Not very portable
Weighing 100 pounds, this unit isn’t easy to transport around when needed.
Con Can't handle low temperatures
When the outside temperature drops below 41 °F, the heat pump will stop working.
Con Bad customer support
Customer reports state that Whynter's customer support is usually very slow and unhelpful.
