Air Conditioning in a Compact, Eco-Friendly Design

The environmentally friendly ARC-12SD is CFC free and designed for minimal energy consumption. This efficient air conditioner uses ozone-safe R-410A refrigerant and lead-free, RoHS-compliant components.

Cools Rooms with Clean, Fresh Air

With 12,000 Btus, this robust unit cools spaces up to 400 square feet with average ambient room conditions. Use it in computer or server rooms, bedrooms, classrooms, living rooms, workshops, and more.

Easy Transport from Room to Room

Outfitted with four multidirectional casters, the unit can be easily wheeled between rooms without being lifted or carried. The unit measures 34 by 20 by 16.5 inches (H x W x D).

Auto Drain Function Removes Condensation

Auto drain technology draws moisture from the air and recycles it to product cool, clean air. The system prevents excess condensation from accumulating, making the unit suitable for continuous, everyday use.

Dual Hose Exhaust for Optimal Airflow and Efficiency

To cool your space efficiently, the ARC-12SD draws warm air from both the inside and outside environment and converts it into cool, clean air. Warm, humid air is then expelled from the room through exhaust hose. Similar to traditional window air conditioners, this system creates improved airflow and efficient cooling.

Three Operational Modes Include Fan and Dehumidifier

The unit offers three modes: cooling, dehumidifying, and fan. Cooling mode cools and dehumidifies the room. To dehumidify without cooling, choose the dehumidifying option. Fan mode circulates air in the room and offers four fan speeds to choose from.

The unit has a dehumidifying capacity of 96 pints per day and an adjustable digital thermostat range of 61 degrees F to 89 degrees F.

Non-Permanent, Easy-to-Install Venting Kit

The easy-install kit includes a window slide bar that fits in standard windows up to 36 inches wide. The slide bar adjusts vertically or horizontally. The kit also includes two extendable exhaust hoses (up to 49 inches) with components for securing the hoses to the unit and the window slide bar.

The ARC-12SD is designed for non-permanent venting through a window, though it can be custom modified to fit into wall openings or dropped ceilings.

Simple Control Panel and Convenient Remote

The control panel features simple selections, including a mode selection button, up/down temperature adjustments, and fan speed selection. Program the unit to activate or shut off at preset times with the 24-hour timer. An included remote control puts the full set of functions at your fingertips.

Washable Pre-Filter and Activated Carbon Filter

The included pre-filter and odor-neutralizing carbon filter help keep cooled air fresh and clean. To clean the pre-filter, simply remove it from the unit and rinse, tap off, or vacuum the accumulated dust. The carbon filter should be replaced every two to three months.

Outfitted with Auto-Restart and Safety Features

During power outages, the auto-restart function will automatically restart the unit at its previous setting. This unit is also supplied with a Leakage Current Detection and Interruption (LCDI) plug, which reduces the risk of fire due to arcing faults in the power supply cord.

What's in the Box

Whynter ARC-12SDH 12,000 Btu Portable Air Conditioner (Frost White), two exhaust hoses, window venting kit, remote control, washable pre-filter, activated carbon filter, and user manual.

By J. Chen on January 22, 2011
Whynter Eco-Friendly 12,000 BTU Dual Hose Portable Air Conditioner, Frost White (ARC-12SD)

Had a need to cool a 380 sq ft study/workroom at our summer home with day time temperatures between 72F-88F. Central air conditioning available but extremely wasteful in a 2500sq ft house. Refused to consider window given prior bad experience (let's just say it took a long fall). This would be my 2nd Whynter portable in less than 10 years. My first one was an odd looking unit that worked wonderfully for years before we gave it away when we had to relocate to overseas.

The shape and design of this unit was agreeable and generally understated. The only hint of technology was the display LCD band that runs along the top half of the a/c. Standard size for a portable and a hint bulkier given the dual hose design. Although termed portable, it is not something you can carry around the house with one hand.

Installation was uncomplicated and the user manual was adequately helpful in completing the window exhaust setup. Understanding the display indications was initially confusing but a quick flip of the user manual was enough to get me comfortable. Remote control is simple and good to at least 15 feet away.

I powered it up during a warm afternoon. I was duly impressed. Sometimes, powerful is probably not the right word. The unit had sufficient fan speed but the actual coolness of the air from the unit was what made the difference. It was exceptionally cold. I was comfortable in a matter of minutes and had actually feeling cold in less than an hour. It's relatively quiet and I've not been bothered but it whatsoever. Several weeks in and it has been performing to expectations.

Whynter Eco-Friendly 12,000 BTU Dual Hose Portable Air Conditioner with Heater, Frost White (ARC-12SDH)

We bought this back in September and took it out again recently for the heater function.

Nicely designed unit that has a clean modern look. The display is a concealed LCD band that is simple and understandable without an overload information and meaningless statistics. Although easy to roll around, be sure to get help when lifting up above a foot. The window kit was good quality and overall setup was considerably easy. Just hookup the hoses to the kit and fit the kit snugly into the window opening.

Cools wonderfully. I use it specifically in the baby's room and occasionally in the study. The dual hose design helps with the energy efficiency and overall cooling or heating out. Both rooms are about 18x18 and this unit has no problem cooling down a 95F room to a comfortable temp in less than 30 mins. I'm surprised that the cooling throughput of this unit is actually 20%-30% faster than another 14000 BTU that I have. Nothing scientific but even my wife notices the significant difference.

The heating option is not for heavy duty heating but it works perfectly as a spot heater when you don't want to crank central heat up too much.

To sum it up, this is a surprisingly efficient unit albeit slightly bulky but gives great bang for the buck.

Cooling: 5 out of 5
This AC unit is used in my office on the 12th floor of an older office building in downtown Cleveland, Ohio. In the case of this older building the HVAC is less than consistent, but the windows do open. Last summer temperatures in my office reached the high 90s on some days. As we are a business formal firm the sauna-like environment in the office was not conducive to wearing a suit and achieving any reasonable productivity. This year, with this AC unit in use for the past three weeks, the office has remained a comfortable 70F with low humidity - even on the hottest day we have had yet this year (93F).

Noise: 4 out of 5
The fan and compressor on this AC unit are a bit noisy, but I think that the noise level is to be expected as the unit has excellent air flow and cools & dehumidifies my office (about 200 sq ft) quickly while helping cool the rest of the suite (about 875 sq ft) too. With the AC unit running on high I have been able to speak on the telephone two exceptions - only twice have I had to switch the AC unit to a lower fan setting in order to hear the other caller(s) on the telephone. This with the unit about five feet from my desk. I have not had any issues with conducting face to face conversations in my office with the AC unit running on high.

Setup: 2 out of 5
Setup did not go was well as I had hoped. The dual hose system is nice and connects to the AC unit very well. However, the screws provided to connect the hose assemblies to the "window kit" were worthless. The hose assemblies popped out immediately. Also the window kit covers a maximum of 36 inches - my office window opening is 42.5 inches.

I am reasonably happy with the unit. It was easy to setup and cools one room quite nicely. So the negative comments I have are more like the 5% I do not like. Keeping that in perspective, the items I would like changed are as follows:

- The unit is a bit noisy. 54dB vs the Sharp 43dB. The Whynter is always running with the sound increasing when the cooling unit is on. I understand the Sharp turns on and off.

- The 6" plastic pipes that connect the unit to the window adapter are very robust. They are a bit tricky to hook up and quite long. I replaced them with ordinary 6" stove pipe - 2 adjustable elbows and 8" of straight pipe. This allowed me to get the unit as close to the wall as possible and minimize the resistance of the pipe itself. I haven't seen any evidence of condensation.

- The unit front panel is not labelled and the remote is poorly labelled. I had to keep the handbook around to see what the LEDs and remote buttons meant. After a while simple things like changing the fan speed are easy to remember. But anything else requires having the manual handy. This was very poorly done.

- This has nothing to do with the unit itself, but it does not cool multiple rooms well at all. I have a bedroom and office across the hall from on another on the second floor. Getting the cool air over to other room requires a number of fans and that does not seem work very well. The temperature differential can be 5 or 8 degrees. Still trying to figure out how to fix that. So buying a portable for multiple rooms requires some additional technology.

This is the first portable air conditioner I have owned so I have nothing really to compare with. So not sure my expectations were realistic. All in all I am as happy with the Whynter as I could expect to be. The only problem I believe I have a right to be annoyed with is the remote and unit display. Cryptic.
