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.

#2 Temprium 10,000 BTU Portable Air Conditioner with WiFi: Best Budget Smart
Why We Picked It
Temprium’s 10,000 BTU ASHRAE portable air conditioner, rated at 6,000 BTU SACC, adds Wi-Fi control and a 50 dB sleep mode for home offices up to 450 sq ft.
This Temprium covers the needs of a typical home office at a lower price than the big brands. It pushes 350 cubic meters per hour of airflow and can deliver air as low as 60°F, so it cools a room quickly before your workday starts. Wi-Fi lets you control it from your phone, set a schedule that matches your hours and turn it off from another room. The sleep mode runs at 50 dB, and the soft ambient light can be switched off fully, which matters if your office doubles as a guest room. A programmable 24 hour timer handles the rest. Temprium suggests it for bedrooms, living rooms, apartments, home offices and garages, and it uses R-32 refrigerant.
Key Specifications

It cools, dehumidifies and runs as a fan. The SmartHome app lets you switch modes, set a schedule and adjust it from anywhere, so the room can be cool when you sit down in the morning and the unit can switch off at the end of your day. Alexa and Google Assistant handle voice commands. Digital controls and an included remote cover use on the unit, and Midea lists the noise at 52.8 dB, so set it to a lower fan speed during calls. The filter is reusable, which keeps running costs down.
Key Specifications

What to Expect from Portable Air Conditioners for Home Offices
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 Portable Air Conditioners for Home Offices
Cooling a Home Office
A home office usually holds a computer, a monitor and one person for many hours, which adds steady heat. A unit with a quiet setting, a timer that starts it before your workday and app control from your phone keeps the room comfortable without interrupting calls. Place it where the airflow reaches your chair, not behind your desk.
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.
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.
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 Portable Air Conditioners for Home Offices
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 noise and scheduling first, then capacity and drainage.
Frequently Asked Questions
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.
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.
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.
How much power does a portable air conditioner use?
Larger units use more power, and running time matters as much as size. Energy saver modes, timers and inverter compressors all reduce the daily total.
Final Verdict
The DREO 8,000 BTU Portable Air Conditioner is the best portable air conditioner for home offices, with a 45 dB listing, drainage-free cooling and full smart control. For Wi-Fi scheduling at a lower price, choose the Temprium 10,000 BTU Portable Air Conditioner with WiFi, and for realistic sizing, the Midea 10,000 BTU ASHRAE Portable Air Conditioner.
