If you want one floor-standing appliance that can cool a room and reduce muggy air, look for a portable air conditioner with a dehumidifier or dry mode. These compressor-based units sit on the floor, roll across one level, and exhaust heat outdoors through a window kit. They are different from standalone dehumidifiers, which remove moisture but do not provide refrigerated cooling.
For most buyers, the Whynter ARC-14S is the strongest all-around choice because its dual-hose design, 9,500 BTU SACC rating, and manufacturer-listed 500-square-foot coverage make it a practical medium-room option. The HUMHOLD 14,000 BTU model has the highest SACC rating in this group, while the DREO 319S and 318S stand out for smart controls and low-setting noise. Feelfunn and Shinco are simpler choices for smaller rooms. Every true portable AC in this guide requires an exhaust hose and a suitable window opening.
- Use the SACC/DOE rating before the larger ASHRAE number when comparing portable AC cooling power.
- Dry mode can reduce room humidity, but it is not a substitute for a properly sized standalone dehumidifier in a persistently damp basement or water-damaged area.
- Measure the window opening and plan the exhaust-hose and drainage route before ordering.

How We Compared These Portable AC Dehumidifier Combos
We prioritized products that are true compressor-based portable air conditioners with a cooling mode, fan mode, and dry or dehumidifier mode. The main comparison points were SACC/DOE cooling capacity, room-use fit, hose design, drainage behavior, low-setting noise, controls, portability, window-kit requirements, and the clarity of current product documentation. Manufacturer coverage claims were treated as guidance rather than guaranteed performance.
Whynter 14,000 BTU Portable Air Conditioner (ARC-14S)
The Whynter ARC-14S is the best-balanced option in this lineup for buyers who want meaningful cooling and dehumidifying in a medium-size room. It is rated at 14,000 BTU ASHRAE and 9,500 BTU SACC, and the manufacturer lists coverage up to 500 square feet. Its dual-hose layout draws and exhausts air through separate hoses, which can reduce the negative-pressure problem common with many single-hose portable units.
It offers cool, fan, and dehumidify functions, three fan speeds, a 61°F to 89°F thermostat range, and a listed moisture-removal capacity of up to 71 pints per day under the manufacturer’s test conditions. The included window kit, hoses, filters, and storage bag make it a complete package. At about 73 pounds, however, it is better rolled across one level than carried between floors.
Best For: Medium-size bedrooms, living rooms, or offices where dual-hose cooling and strong moisture removal matter more than compact size.
Why You’ll Like It: It combines a comparatively strong SACC rating with a dual-hose design and useful dehumidifying capacity.
Who Should Avoid It: Buyers who need a lightweight unit, a very quiet compressor cycle, or an appliance that can cool several separated rooms.
Pros:
- 14,000 BTU ASHRAE and 9,500 BTU SACC cooling ratings.
- Dual-hose setup can improve room-air balance compared with basic single-hose designs.
- Includes the main installation accessories and a washable pre-filter.
Cons:
- Heavy and bulky at about 73 pounds.
- Compressor and airflow noise may still be noticeable in a quiet bedroom.
- Requires space for two hoses and a compatible window opening.
HUMHOLD 14,000 BTU Portable Air Conditioner
The HUMHOLD model is the highest-capacity single-hose option kept in this guide. It is listed at 14,000 BTU ASHRAE and 10,000 BTU SACC, with manufacturer-stated coverage up to 700 square feet. That makes it worth considering for a larger open room, although heat load, insulation, sun exposure, and doorway traffic will affect the area it can cool comfortably.
Its cool, fan, and dry modes are joined by smart mode, sleep mode, three fan speeds, auto-swing, a 24-hour timer, and a remote. The manufacturer lists up to 95 pints per day of dehumidification under test conditions. Automatic evaporation can reduce routine draining, but a drain hose may still be necessary in very humid weather or while using dry mode.
Best For: Buyers who need the highest listed SACC rating in this group for one larger enclosed bedroom, living room, apartment area, basement room, or office.
Why You’ll Like It: The 10,000 BTU SACC rating, broad airflow, remote controls, and dry mode make it a flexible large-room option.
Who Should Avoid It: Anyone who must lift the unit frequently or who has a crank-out window that cannot accept the supplied slider kit without an adapter.
Pros:
- 14,000 BTU ASHRAE and 10,000 BTU SACC ratings.
- Cooling, fan, and dehumidifier modes with sleep and smart functions.
- Washable filter, casters, auto-swing, remote, and timer.
Cons:

- May require continuous drainage in high humidity.
DREO Portable Air Conditioner 319S Smart 3-in-1 AC
The DREO 319S is the better DREO choice when you want app and voice control with more cooling headroom than the 318S. It is rated at 10,000 BTU ASHRAE and 6,000 BTU SACC, with listed coverage up to 200 square feet. The 3-in-1 design provides cool, fan, and dry modes, while the adjustable thermostat runs from 61°F to 86°F.
DREO lists operation as low as 45 dB on its lowest setting, plus control through the app, remote, touch panel, Alexa, Google Assistant, and Siri. Its moisture-management design is intended to reduce routine draining during cooling, but drainage requirements still depend on humidity and operating mode.
Best For: Smart-home users cooling a small bedroom, home office, studio, or similar enclosed room.
Why You’ll Like It: It offers the strongest cooling rating of the two DREO models here without giving up app scheduling, voice control, or low-setting quietness.
Who Should Avoid It: Buyers expecting a 10,000 BTU portable unit to cool a large open-plan area; its SACC rating and listed coverage point to a smaller-room use case.
Pros:
- 10,000 BTU ASHRAE and 6,000 BTU SACC ratings.
- App, voice, remote, and touch controls.
- Low-setting noise listed at 45 dB.
Cons:
- Listed coverage is only about 200 square feet.
- At 57.2 pounds, it is rollable but not especially light.
- Dry mode or very humid conditions may still require drainage.
DREO Portable Air Conditioner 318S (8,000 BTU Smart AC)
The DREO 318S is the compact smart option for a small bedroom or office. Its 8,000 BTU ASHRAE and 5,000 BTU SACC cooling system is listed for spaces up to 150 square feet, and it offers cool, fan, and dry modes. The smaller coverage figure is more realistic than trying to stretch an entry-level portable unit across a large living area.
You can adjust it through the DREO app, remote, touch panel, Alexa, Google Assistant, or Siri. The manufacturer lists noise as low as 45 dB, making it one of the quieter low-setting options in the group. A self-evaporation system reduces routine water handling during normal cooling, while a drain connection is available when conditions demand it.
Best For: Small bedrooms, offices, dorm-style rooms, and enclosed spaces where smart controls and lower noise matter.
Why You’ll Like It: It combines compact-room cooling with app schedules, voice control, and a low listed sound level.
Who Should Avoid It: Buyers trying to cool a large, sunny, poorly insulated, or open-plan room.
Pros:

Factors to Consider When Choosing a Floor Air Conditioner With Dehumidifier Mode
The right unit depends on more than the largest BTU number. Compare SACC cooling capacity, room heat load, hose design, drainage needs, noise, controls, window compatibility, electrical requirements, and energy information. A correctly sized and properly sealed portable AC will usually perform better than an oversized model with a leaking window panel or a long, kinked exhaust hose.
ASHRAE vs. SACC Cooling Capacity
Portable AC listings often show two cooling numbers. ASHRAE BTU is the larger laboratory capacity, while SACC or DOE BTU accounts more realistically for heat added by the exhaust system and air infiltration. Use SACC first when comparing two portable units. A 14,000 BTU ASHRAE model may have a SACC rating closer to 9,500 or 10,000 BTU, so comparing only the large headline number can be misleading.
Room Size and Heat Load
Measure the room and then adjust for real conditions. Direct afternoon sun, poor insulation, high ceilings, several occupants, cooking appliances, and open doorways all increase the cooling load. Manufacturer coverage figures are useful for rough comparison, but they are not guarantees. For difficult rooms, choose based on SACC and avoid sizing at the absolute upper limit.
Hose Design and Window Fit
Every compressor-based portable AC in this guide must vent hot air outdoors. Confirm that the included slider panel fits your window type and opening width. Standard kits usually suit vertical or horizontal sliding windows, while casement or crank-out windows may need a separate seal. Keep the exhaust hose short, straight, and fully extended only as needed. Dual-hose designs can reduce negative pressure, while single-hose models are usually simpler and less bulky.
Dehumidifier Mode and Drainage
Dry mode can make a warm room feel more comfortable by removing moisture, but it does not turn a portable AC into a whole-home dehumidifier. Pints-per-day ratings are measured under specified temperature and humidity conditions and may not match your room. Self-evaporation can reduce bucket emptying during normal cooling, yet high humidity or dedicated dry mode may require a drain hose. For persistent dampness, water intrusion, or a large basement, use a properly sized standalone dehumidifier instead.
Noise Levels
Portable ACs place the compressor inside the room, so they are usually more noticeable than central air or many window units. Low-setting figures around 45 to 55 dB are useful for comparison, but compressor startup, cycling, vibration, and high fan speed can sound louder. For a bedroom, place the unit on a level floor, keep it away from rattling furniture, and choose sleep mode if available.
Energy Efficiency
Do not compare portable ACs by SEER alone or by unclear claims such as “annual watts.” Look for the current CEER, EER, SACC/DOE capacity, input wattage, and EnergyGuide information. Timers, sleep schedules, clean filters, a sealed window kit, and a sensible thermostat setting can reduce wasted runtime. An oversized unit is not automatically more efficient and may cycle before removing enough humidity.
Electrical Safety and Outlet Requirements
Portable air conditioners draw substantial current when the compressor starts. Use the grounded wall outlet and circuit specified in the product manual, keep the plug accessible, and avoid extension cords, power strips, or undersized smart plugs. Do not defeat the grounding pin or share an overloaded circuit with other high-draw appliances.
Portability and Maintenance
Casters make a 50- to 73-pound appliance easy to roll on one level, but they do not make it easy to carry upstairs. Check handle placement, dimensions, hose storage, and whether the filter can be removed without tools. Clean the filter according to the manual, inspect the drain plugs, and keep the air inlet and outlet clear.
- Measure the room and window opening.
- Compare SACC/DOE, not only ASHRAE BTU.
- Check whether your window needs a special seal.
- Plan a drainage route for very humid conditions.
- Confirm the grounded circuit and outlet meet the manual’s requirements.
- Allow clearance around the air intake and exhaust.
Frequently Asked Questions
How Often Should I Clean the Filter and Drain System?
Follow the product manual first. A practical starting point is to inspect the filter every two weeks during frequent use and clean it whenever dust is visible. Check drain plugs, hoses, and any internal tank regularly, especially in humid weather. Always switch off and unplug the unit before cleaning.
Can These Units Run Overnight?
They can usually run overnight when installed and operated according to the manual. Keep the exhaust hose secure, maintain the required clearances, use a grounded wall outlet, keep the filter clean, and arrange drainage if the tank may fill. Sleep mode can reduce fan speed, but it does not make the compressor silent.
Do I Need a Window Kit for Every Portable AC?
Yes for the compressor-based portable air conditioners in this guide. They must exhaust heat outdoors through a hose. Small “ventless air conditioners” are normally evaporative coolers, not refrigerated ACs, and they can add moisture to the room. That makes them a poor substitute in already humid conditions.
How Noisy Are Portable AC Dehumidifier Combos at Night?
Most are audible because the fan and compressor are in the room. Low settings commonly fall in the mid-40s to mid-50s dB range, but cycling and vibration may sound louder than the published number suggests. Light sleepers should prioritize low-setting noise, sleep mode, stable placement, and enough distance from the bed.
Is Dry Mode the Same as a Standalone Dehumidifier?
No. Dry mode is useful for cooling one room while reducing humidity, but its controls, drainage behavior, and operating range differ from a dedicated dehumidifier. A standalone unit is usually the better tool for a damp basement, crawl space, water-damage problem, or whole-area moisture control.
Can I Use a Smart Plug With a Portable Air Conditioner?
Only when the appliance manual explicitly allows it and the smart plug is specifically rated for the unit’s running current and compressor startup load. Some portable ACs do not restart automatically after power is restored, and an undersized plug can overheat. A direct grounded wall outlet and the unit’s built-in timer or app are the safer default.
Conclusion
The best floor air conditioner dehumidifier is really a properly sized portable AC with a useful dry mode. For the strongest all-around combination, the Whynter ARC-14S is the first model to compare because it pairs a 9,500 BTU SACC rating with a dual-hose design. HUMHOLD has the highest listed SACC capacity in this group, DREO 319S is the best smart option, and DREO 318S makes more sense for a small room where low-setting noise and app control matter.
Feelfunn and Shinco are simpler small-room alternatives, but their coverage should be sized conservatively. Before ordering any model, measure the room and window, confirm the SACC rating, and decide where the exhaust hose and drain water will go. Those checks matter more than chasing the largest advertised BTU or square-foot number.
