Whynter ARC-143MX Portable Air Conditioner Review

The portable Whynter ARC-143MX air conditioner with a built-in dehumidifier is a champ at quickly cooling a room even on the hottest of days.

This AC unit is well-suited for data centers, server rooms and wiring closets that are 500 square feet or less. However, it also works efficiently in residential settings.

Whynter focused on making the dual-hose ARC-143MX energy efficient and environmentally friendly. It boasts a high BTU rating along with lead-free components and CFC-free refrigerant.

The LCD display and push-button controls allow you to choose from three different operations modes and fan speeds as well as timer and thermostat settings. To rid the air of particles, this air conditioner comes equipped with an antimicrobial air filter, carbon filter, and pre-filter.

Plus, its advanced auto-drain feature exhausts most of the condensate, meaning you do not have to remove and empty a messy, cumbersome reservoir tank. It also includes exhaust and intake hoses that extend up to 60 inches and a window kit that adjusts from 20 inches to 46 inches.

Eco-Friendly Cooling

This impressively powerful air conditioner has a 14,000 BTU and 11.2 EER rating as well as a dual-hose operation. When combined, these three features provide more than adequate cooling without the shock of a high electricity bill.

Additionally, it only uses ozone-safe R-410A refrigerant. Plus, the electronic components of the unit meet ROHS compliance standards, which forbid the use of hazardous substances like lead and mercury.

More Than Just an Air Conditioner

An air conditioner, fan, and dehumidifier – This freestanding unit has it all. The ability to choose between three operational modes from the control panel and remote control allows you to run the air conditioner, fan or the dehumidifier at your leisure.

The AC unit comes equipped with a standard reusable pre-filter that traps dirt, pet hair and other allergens. However, Whynter went above and beyond by adding an activated carbon filter to remove odors from the air. It even has an Antimicrobial High Air Flow air filter from 3M that stops mold and mildew growth and keeps the air free of particles that could damage expensive equipment.

The fan mode has a low, medium and high-speed option. For fast cooling without operating the AC mode, the fan’s highest speed works well. Another reason this portable air conditioner is such a gem is its dehumidifier mode. With a 91-pint capacity and advanced auto-drain feature, you will rarely have to manually drain the reservoir.

In regular ambient conditions, the self-evaporate system utilizes recycled moisture to blow cold air into the room and exhaust the condensate.

In the event the reservoir becomes full, you only need to turn off the unit, place a container underneath it and remove the drain plug. In about 5 minutes, the air conditioner will be ready to use again.

Must-Have Features

This unit’s control panel is a mini-hub of convenience. Its LCD display lets you easily adjust the digital thermostat from 61 degrees Fahrenheit to 89 degrees Fahrenheit. If you prefer to view the Celsius measurement, simply press and hold the up and down buttons; setting the 24-hour timer is just as easy.

For your safety, the AC unit has a warning light and auto-shut off feature, both of which will activate when the reservoir must be drained. If the electricity goes out, the air conditioner will automatically restart once the power returns.

Conclusion: Should I Buy the Whynter ARC-143MX Portable Air Conditioner?

The main concern for users is usually how fast an air conditioner can cool a room. With its dual-hose setup, high BTUs and efficient EER rating, the cooling performance of the Whynter ARC-143MX portable air conditioner is top notch.

Its caster wheels and window kit make it a snap to install, especially in comparison to window units that must be toted and hoisted, and unlike many reservoirs, this air conditioner’s tank does not need to be taken out in order to dump the water.

The only feature missing is a light dimmer for the LCD display. However, this is easy to work around by simply taping a piece of paper over it, so the absence of a dimmer is not a deal breaker. All aspects considered, this freestanding AC unit is worth every dollar.
