The Whynter ARC-14S is still on the shelf, and it is still the dual-hose benchmark. Here is why two hoses matter, and what else is worth a look.

Good News: the Whynter Is Still Here
The old page reviewed the Whynter ARC-14S 14,000 BTU dual-hose portable AC. A check on Amazon on October 20, 2026 found it in stock at $439.99. The old page also offered a Sylvane price button. That store link is not checked here, so the buttons below point to Amazon only.
Why Two Hoses Matter
A single-hose portable uses room air to cool its hot side, then blows that air outside. The room has to replace it, so hot outside air leaks in. A dual-hose unit takes air from outside, uses it and sends it back out. The room is no longer fighting itself. In practice, that means a dual-hose unit often cools a bit faster at the same BTU.
Real BTU vs Box BTU
The Whynter is sold as a 14,000 BTU unit on the old test. The DOE test gives a lower number, so size the room for the lower number. Try the BTU calculator with the room size and sun exposure. The old page said the unit covers 500 square feet, which is on the generous side.
Here is the quiet shift in portable ACs: dual-hose designs are moving from niche to mainstream. Whynter led the way with the ARC-14S, and brands like Midea now call their dual-hose models Duo. The reason is simple. Pulling outside air for the hot side of the machine stops it from sucking warm air in through your cracks.
3 Dual-Hose Portable ACs
Rechecked on Amazon on October 20, 2026. Prices, ratings and buttons are below.
Price on Amazon: $439.99 | 4.3 stars from 12,564 ratings (checked October 20, 2026)
The Whynter ARC-14S is still on Amazon, which is rare for an older portable. It costs $439.99 and has a 4.3 rating from over 12,500 ratings. That is a very large pile of owners for a unit at this price.
Price on Amazon: $549.99 | 4.0 stars from 253 ratings (checked October 20, 2026)
The Midea Duo 14,000 BTU is the newer dual-hose option, and this version adds heat. It costs $549.99, with a 4.0 rating from 253 ratings. A smaller 12,000 BTU Midea Duo costs $621.37, with a 3.6 rating from over 1,300 ratings.
Price on Amazon: $699.00 | 3.5 stars from 128 ratings (checked October 20, 2026)
The LG 10,000 BTU SACC dual inverter is the premium choice. It costs $699.00 and has a 3.5 rating from 128 ratings, so read the reviews before you spend this much.
The downside is size and price. Dual-hose units are heavier, taller and cost more. The Whynter weighs 80 pounds per the old page, and the Midea Duo and LG inverter versions sell for $549.99 to $699.00. Extra hoses and brackets also add clutter. Expect more of the accessory upsell that the old page complained about.
The Accessory Problem
The old page raised a complaint worth repeating: many owners felt there were too many accessories sold separately. That includes hose extenders, window slide bars and extra filters. Before you buy, check what is in the box, and price any add-ons you need.
Weight and Moving
At 80 pounds, the Whynter is not a unit you lug up stairs every day. It has casters, so you can roll it from room to room. Plan one spot, with a window nearby, and leave it there for the season.
Running Cost
The old page lists 1,250 watts. At 15 cents a kilowatt hour, that is about 19 cents an hour, or about $45 for a month of eight-hour days. See our best portable air conditioners guide for the full list.
The Pick
Want the proven one? The Whynter. Want heat in winter? The Midea Duo 14,000. Want quiet and have money to spend? The LG inverter. A 12,000 BTU class room?

FAQ
Is the Whynter ARC-14S still sold?
Yes. Amazon lists it at $439.99 as of October 20, 2026.
Are dual-hose portable ACs better?
Usually yes, because they do not pull room air out and let warm air in.
How heavy is the Whynter ARC-14S?
About 80 pounds per the old page.
How much does it cost to run?
About 19 cents an hour at 1,250 watts and 15 cents a kilowatt hour.
Final Word
Two hoses beat one. The Whynter is the proven pick, the Midea Duo adds heat and the LG is the quiet splurge.
What comes next: inverters and heat pump versions, then stricter tests that make the numbers on the box line up better. Until then, read the DOE number first, and the brand number second.
