Both of these are dual-hose portable air conditioners aimed at a room too big or too awkward for a window unit, so the honest choice comes down to your climate more than raw cooling power. The Whynter ARC-14S is the long-standing, widely owned dual-hose classic — a safe, proven pick for a large room's indoor climate. The Honeywell 14,500 BTU unit covers slightly more square footage and adds a genuinely high-capacity dehumidifier rated at 101 pints a day, which matters if your summers are humid rather than just hot. Get the BTU and dehumidifying capacity matched to your room and either will hold a comfortable indoor climate; mismatch them and neither will.

Cooling capacity, BTU, and square footage: which one cools a bigger room?
The Honeywell has the edge on paper, rated for rooms up to about 700 square footage against the Whynter's roughly 500. Both are dual-hose units in the 14,000+ BTU class, so cooling capacity in a real room is closer than the spec sheet suggests.
Coverage numbers on any portable air conditioner, including models from Midea, LG, and DeLonghi, are measured under ideal conditions. Treat both of these as strong large-room performers rather than fixating on the exact square-footage gap. What actually decides comfort is how well the window kit is sealed and whether the room has unusual heat load. Size to the room you actually have, not just the number on the box.
Does the dehumidifier rating actually matter?
It matters a great deal in a humid climate and much less in a dry one. The Honeywell's 101-pint rating is well above typical for this class. Owners in muggy regions report noticeably drier air alongside the cooling. In a dry climate, both units' dehumidifying is closer to a rounding error.
Every portable air conditioner removes some moisture as a side effect of cooling. That is what the condensate line is for. The Honeywell simply does more of it by design, a genuine advantage in a basement or anywhere summers run muggy. If you live somewhere dry, this spec should not weigh much in your decision.
Dual-hose vs single-hose: is dual-hose worth it over single-hose on either brand?
Yes, on both. A dual-hose unit draws air from outside through a dedicated exhaust hose instead of pulling it from the room you are cooling. It reaches temperature faster and runs more efficiently than a single-hose design. Both the Whynter and this Honeywell use the dual-hose format.
Single-hose portable ACs exhaust room air outside, then pull in unconditioned replacement air through gaps in the house — a known efficiency drag. Because both of these units already use dual hoses, that debate is settled before you even compare brands. The choice here is about room size and dehumidifying need, not hose count.
Exhaust hose setup and window kit sealing
Both ship with a window venting kit and a rigid exhaust hose that connects to it. A loosely sealed window kit is the single most common cause of "my portable AC isn't cooling" complaints for any brand. Take the extra few minutes to seal gaps around the kit with foam or tape on either unit.
CFM, compressor, and SEER: how portable AC ratings work
CFM measures how much air the internal fan moves; compressor size and refrigerant type determine cooling capacity; SEER-style efficiency ratings describe how much cooling you get per watt drawn. Portable units generally post lower SEER numbers than a mini-split or central system, since the design trades some efficiency for mobility.
Both the Whynter and Honeywell use a rotary compressor built for continuous cycling, the same core technology used across the category by Midea, LG, and DeLonghi. Higher CFM generally means faster room-air turnover, which is part of why the larger Honeywell unit covers more square footage.
Self-evaporating design and running cost: what affects energy efficient use?
Both units use a partly self-evaporating design, meaning some condensate is recirculated across the hot coil and evaporated out through the exhaust hose instead of collecting in a tank. That cuts how often you empty water, and it is standard on most ENERGY STAR-class portable units today.
Running cost on a portable air conditioner tracks BTU and hours of use, not brand. An energy efficient habit that helps both units: seal the window kit well and close doors to the room being cooled, so the compressor is not fighting a constant infiltration of warm outside air.
Noise level and remote control: everyday livability
Both units include a remote control for adjusting temperature and fan speed from across the room. Noise level is a genuine differentiator in this category — a compressor-driven portable AC is louder than a simple fan, and owners consistently rate quieter operation as a top request.
Neither brand publishes a decibel rating that owners treat as gospel, so real-world noise level reports from buyers are the more reliable signal. Both are livable in a bedroom on a lower fan setting, though the compressor cycling on is audible on either unit.
Spot cooling vs whole-room portable air conditioner: when is a smaller unit enough?
If you only need spot cooling for a desk or a single corner, a smaller single-hose unit is cheaper and simpler than either of these dual-hose models. Both the Whynter and Honeywell are built for whole-room cooling, not a quick localized fix.
A dedicated spot cooler also skips the window kit entirely on some designs, venting through a small hose tucked behind furniture. That convenience comes at the cost of real cooling capacity — neither a spot cooler nor a small single-hose unit will handle a 500-square-foot room the way the Whynter or Honeywell can. Reserve the smaller format for a room you already keep cool by other means and just need to take the edge off one corner.
Window kit and installation: what does setup actually involve?
Both the Whynter and Honeywell ship with an adjustable window kit sized for most standard double-hung and sliding windows. Setup is a DIY job: extend the kit panel to fit the window opening, secure the exhaust hose fitting, and plug in the unit.
Owners who take the extra step of taping foam seals around the window kit report noticeably better cooling and lower running cost than those who leave gaps. This single habit matters more for real-world performance than any spec difference between the Whynter and Honeywell models.
Which brand has the longer track record?
Whynter, by a clear margin in this specific product line. The ARC-14S dual-hose format has been a steady, widely owned pick for years, with a long history of owner reviews. Honeywell is a much larger, longer-established company overall, but this high-capacity dehumidifying model is newer to its portable AC lineup.
Longevity in a specific product line matters because more owners have lived with the unit through multiple summers. That surfaces long-term issues a newer model has not had time to reveal. This favors the Whynter for buyers who weigh a proven track record heavily.
Best for a large room where you want proven dual-hose cooling
- 14,000 BTU cooling for rooms up to about 500 sq ft
- Dual-hose design for faster, more efficient cooling
- Built-in dehumidifier and fan-only mode
- Washable pre-filter and included window venting kit
Why buy it: Whynter built its name on the dual-hose format, and owners consistently point to it as the reason this unit cools faster and keeps the room from turning slightly negative-pressure the way single-hose units can. It has been a steady go-to pick for large rooms in years.
Best for a big room in a genuinely humid climate
- 14,500 BTU (10,000 BTU SACC) for rooms up to about 700 sq ft
- Dual-hose cooling
- Rated to pull up to 101 pints of moisture a day
- Remote control and included window kit
Why buy it: The consensus favors the Honeywell when the room is not just hot but muggy — that 101-pint dehumidifier rating is well above what most portable ACs offer, and owners in humid climates report it noticeably dries the air on top of cooling it.
The verdict
For most large rooms, the Whynter ARC-14S is the dependable default — a proven dual-hose design with a long track record. Step up to the Honeywell 14,500 BTU if your room runs on the bigger side or your climate is genuinely humid; the extra coverage and the 101-pint dehumidifier rating earn their keep there. Neither is the wrong buy — match the unit to your square footage and your climate, not just the brand name.
