LG’s 5,000 BTU SACC portable AC is a simple, quiet small room unit rated for 150 sq ft, about a 10 by 15 foot room, with a 24 hour timer and an LCD remote.
This LG model is about simplicity. It cools rooms up to 150 sq ft, which LG translates to a 10 by 15 foot room, a typical single dorm or small bedroom. Three modes cover cooling with dehumidifying, fan circulation and dry mode for damp days. The remote and a top-mounted LED display with a 24 hour timer let you set the temperature precisely, and LG lists auto clean, a dust filter and a filter light reminder in its specifications. LG describes it as quiet, with a listed 50 dB, and it runs on standard 115V power. The window installation kit is included. It does not have Wi-Fi, but for a dorm that only needs reliable cooling and an easy setup, the simplicity is a plus.

DREO’s 318S is a smart 8,000 BTU ASHRAE portable air conditioner with a listed 45 dB noise level, drainage-free cooling and app, voice and touch control, which suits a home office used for calls.
Noise is what makes or breaks a home office AC, and DREO builds this one around it, with a listed 45 dB that sits comfortably below the level that interferes with video calls. It is rated at 5,000 BTU SACC, a good match for a spare bedroom office or a small study, and DREO says its IceCool system throws air up to 14 ft. Cool, Fan and Dry modes each have three functions to fine-tune, and the temperature can be set from 61°F to 86°F. Cooling mode is drainage-free, so there is no tank to check during the workday. You can control it from the touchpad, the large LED display, the app, the remote or by voice through Alexa or Google Assistant, so you can start it before your first meeting.

Why We Picked It
Keystone’s 8,500 BTU ASHRAE portable air conditioner is rated at 5,000 BTU DOE for rooms up to 200 square feet and adds auto restart, which turns it back on after a power outage.
Auto restart is a small feature that matters if you run the unit while you are away: after a power cut, it comes back on at the last temperature it was set to, so a pet or a room full of electronics is not left without cooling. Keystone rates it at 5,000 BTU DOE for apartments, bedrooms and small rooms up to 200 square feet. It has three fan speeds and dehumidifies up to 2 pints per hour. The included window venting kit makes installation simple and lets you move the unit between rooms. A clean filter alert tells you when to rinse the washable filter, and a remote is included. It runs on standard 115V power and weighs 47.18 pounds.
Key Specifications
- Cooling: 8,500 BTU ASHRAE, 5,000 BTU DOE
- Coverage: Up to 200 square feet
- Fan speeds: 3
- Dehumidifying: Up to 2 pints per hour
- Extras: Auto restart, clean filter alert
- Filter: Washable
- Power: 115V

This portable air conditioner is best for small bedrooms and rooms that must stay cool through outages.

What to Expect from 5,000 BTU 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 5,000 BTU 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.
What Compact Means
Compact portables use smaller cabinets and lower capacity, which makes them easier to move and fit beside furniture. The trade-off is less cooling, so they suit bedrooms, offices and dorm rooms rather than open living areas. Check both the dimensions and the weight, because some compact units are short but still heavy.
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 5,000 BTU 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 DOE or SACC capacity 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.
Do compact portable ACs cool as well as larger ones?
They cool smaller spaces well, but they have less capacity. Match the listed room size to your room rather than buying the smallest unit available.
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.
Is it safe to run a portable AC all night?
Yes. Use sleep mode to quiet the fan and raise the set point gradually, and make sure the unit can drain or will stop safely if the tank fills.
Final Verdict
The LG 5,000 BTU SACC (8,500 ASHRAE) Portable AC is the best 5,000 BTU Portable Air Conditioner for most people, with an honest SACC rating and a quiet 50 dB listing. For a quiet smart unit, choose the DREO 8,000 BTU Portable Air Conditioner, and for rooms that must stay cool through outages, the Keystone 8,500 BTU ASHRAE Portable Air Conditioner.
