#1 COSTWAY 10,000 BTU Portable Air Conditioner: Best Overall
Why We Picked It
COSTWAY’s 10,000 BTU portable air conditioner is a simple 4-in-1 unit with ventilating, drying, cooling and sleep modes at a low price for a 10,000 BTU unit.
This is a basic, budget-minded unit. Four modes cover ventilation, drying, cooling and sleep, and two fan speeds let you balance airflow and noise. The operation panel and the remote both give full control, so you can adjust it from across the room. The filter is washable, so there is nothing to replace, and the specifications list R-410A refrigerant. COSTWAY lists the noise at 60 dB, which is loud, so it is better for a living area, a garage or an office than for a bedroom where you sleep. It is a reasonable choice if you want 10,000 BTU of cooling without paying for smart features or an inverter.
Key Specifications

What to Expect from COSTWAY Portable Air Conditioners
A portable air conditioner is a complete refrigeration unit on wheels. It pulls warm room air across a cold coil, sends the cooled air back into the room and pushes the heat it removed outside through an exhaust hose that runs to a window. Because the hot side and the cold side share one cabinet indoors, a portable unit works harder than a window unit of the same rating, but it needs no permanent installation and can move from room to room.

How to Choose COSTWAY Portable Air Conditioners
ASHRAE vs SACC Ratings
Portable AC boxes often show two numbers. The larger ASHRAE figure is measured under ideal lab conditions and does not account for the heat that leaks back from the exhaust hose. The smaller SACC figure, which the Department of Energy uses, reflects real-world portable use. Compare units by their SACC or DOE rating when a listing gives one, and treat the ASHRAE number as a ceiling.
Match the Unit to the Room
Start with the room size the manufacturer lists, then adjust. Sunny rooms, high ceilings, kitchens and rooms with several people need more capacity, while shaded rooms need less. An undersized unit will run constantly without catching up, and an oversized unit cools quickly but removes less humidity, so the room can feel clammy.
Check the Noise
Every portable AC has its compressor in the room with you, so noise matters. Look for a decibel figure on the listing, a sleep mode that slows the fan and dims the display, and an inverter compressor, which ramps up and down instead of cycling hard on and off. Quiet settings usually mean less airflow, so a slightly larger unit run on low can be quieter than a small unit on high.
Controls and Smart Features
Nearly every portable AC now includes a remote, a timer and several modes such as cool, dry and fan. Smart models add Wi-Fi control from a phone app, schedules and voice control through Alexa or Google Assistant, so you can start cooling before you get home. A remote with its own temperature sensor helps the unit cool the spot where you sit rather than the air right around the cabinet.
Drainage and Self-Evaporation
Every air conditioner pulls water out of the air. Many portable units evaporate most of it and blow it out with the exhaust, so in normal conditions you rarely need to drain them. In very humid weather or in dehumidifier mode, water can collect in an internal tank, and the unit will stop when it is full. A drain port that accepts a hose lets you run it continuously into a floor drain or bucket.
How We Evaluate COSTWAY Portable Air Conditioners
We rank these units on manufacturer specifications and listing details: cooling capacity, the room size the maker lists, noise, controls, setup, power use and price. We kept only new, in-stock units and left out accessories, renewed listings, color duplicates and listings with too little data. For this list we weighed capacity and price first, then noise and features.
Frequently Asked Questions
Should I trust the ASHRAE or the SACC rating?
Use the SACC or DOE rating to compare portable units. It accounts for real-world heat losses and is always lower than the ASHRAE number printed on the box.
Does a portable air conditioner need a window?
Yes, in almost every case. The exhaust hose has to send the heat outside, usually through a window, a sliding door or a wall vent. A unit with nowhere to vent only moves heat around the room.
Do portable air conditioners need to be drained?
Many evaporate most of the water they collect and rarely need draining, but in humid weather or dehumidifier mode the internal tank can fill. A drain hose lets the unit run continuously.
Is a single hose portable AC good enough?
For bedrooms, offices and moderate climates, yes. Dual hose units cool faster in very hot weather and large rooms, but single hose models are lighter, cheaper and simpler.
Final Verdict
The COSTWAY 10,000 BTU Portable Air Conditioner is the best COSTWAY Portable Air Conditioner for most people, with 10,000 BTU of cooling at a low price. For a slim footprint and a sleep mode, choose the COSTWAY 10,000 BTU Portable Air Conditioner with Sleep Mode, and for DOE certification and an included drain hose, the COSTWAY 8,200 BTU Portable Air Conditioner.
