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.
Key Specifications
- Cooling: 8,000 BTU ASHRAE, 5,000 BTU SACC
- Noise: 45 dB
- Air throw: Up to 14 ft
- Drainage: Drainage-free in cool mode

#2 LG 6,000 BTU Smart Portable Air Conditioner: Best Quiet LG
Why We Picked It
LG’s smart portable AC lists 6,000 BTU on the DOE scale and 8,000 BTU ASHRAE, cools rooms up to 250 sq ft and adds Wi-Fi app and voice control to LG’s simple, quiet design.
LG makes the setup simple: wheel it into place on the built-in casters, fit the included window kit and start cooling. Two fan speeds help circulate air, and LG describes the operation as quiet enough to run day and night without disturbing work or sleep, with a listed noise level of 50 dB. The Wi-Fi connection lets you control it from LG’s app or by voice, so you can start cooling a bedroom before bed or a home office before you sit down. LG suggests it for bedrooms, garages and home offices. The specification sheet adds auto clean, fast cooling and a timer, and it uses R-32 refrigerant. Listing both DOE and ASHRAE numbers makes it easy to compare with other units honestly.
Key Specifications
- Cooling: 6,000 BTU DOE, 8,000 BTU ASHRAE
- Coverage: Up to 250 sq ft
- Controls: Wi-Fi app, voice, remote
- Fan speeds: 2
- Noise: 50 dB
- Extras: Auto clean, timer
- Refrigerant: R-32
| Pros | Cons |
|---|---|
|
|
Things to Consider
With two fan speeds and no inverter, it is simple rather than feature packed. If you do not need app control, LG’s non-smart version costs less.
Best For
This portable air conditioner is best for bedrooms and home offices where you want app control.

#3 Temprium 8,000 BTU Smart Portable Air Conditioner: Best Quiet Budget
Why We Picked It
Temprium’s 8,000 BTU smart portable air conditioner cools rooms up to 350 sq ft, runs at 50 dB in sleep mode and adds Wi-Fi control at a low price.
Temprium designed this unit for light sleepers. Sleep mode runs at 50 dB, and the soft ambient light can be closed off completely, so it does not light up a dark bedroom or nursery. An upgraded high-efficiency compressor and 320 cubic meters per hour of airflow can bring the air down to 60°F, and Temprium rates it for rooms up to 350 sq ft, covering bedrooms, living rooms, apartments, garages and home offices. Four modes cover cooling, fan, dry and sleep, and a programmable 24 hour timer lets you set it to switch off after you fall asleep. Wi-Fi control lets you adjust it from your phone. The cabinet measures 11.5 by 12 by 27 inches and weighs 41.56 pounds, light for an 8,000 BTU unit.
Key Specifications
- Cooling: 8,000 BTU ASHRAE
- Coverage: Up to 350 sq ft
- Airflow: 320 m³/h
- Noise: 50 dB in sleep mode
- Modes: Cool, Fan, Dry, Sleep
- Controls: Wi-Fi, 24 hour timer
- Weight: 41.56 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
Temprium does not list a SACC figure, so expect real output below the headline. In a sunny room, a larger unit will keep up better.
Best For
This portable air conditioner is best for bedrooms and nurseries where quiet and darkness matter.
Check the current price and availability of the Temprium 8,000 BTU Smart Portable Air Conditioner on Amazon.

Garvee 8,000 BTU Portable Air Conditioner. This Garvee 8,000 BTU unit cools 350 sq ft with an LED display, a timer and sleep mode, at a listed 48 dB.
GE 8,000 BTU Portable Air Conditioner. GE’s 8,000 BTU unit is rated at 5,100 BTU SACC for 150 sq ft, with auto evaporation and a no-cut window kit.
What to Expect from Quiet 8,000 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 Quiet 8,000 BTU Portable Air Conditioners
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.
Why Inverter Compressors Matter
An inverter compressor changes speed to match the cooling the room needs instead of switching on and off at full power. That keeps the temperature steadier, cuts noise and lowers power use once the room has cooled down. Inverter portables cost more up front but are the better choice for bedrooms and rooms you cool for many hours a day.
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.
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.
How We Evaluate Quiet 8,000 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 the listed noise level first, then capacity and controls.
Frequently Asked Questions
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.
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.
Is a portable AC loud enough to bother calls?
Many models are quiet enough on low or sleep mode for video calls. Check the listed decibel figure and place the unit away from your microphone.
Final Verdict
The DREO 8,000 BTU Portable Air Conditioner is the best Quiet 8,000 BTU Portable Air Conditioner for most people, with a 45 dB listing and drainage-free cooling. For LG’s quiet design with Wi-Fi, choose the LG 6,000 BTU Smart Portable Air Conditioner, and for a 50 dB sleep mode at a low price, the Temprium 8,000 BTU Smart Portable Air Conditioner.
