A portable air conditioner allows you to enjoy a touch of central air conditioning with the convenience of an old-fashioned window unit. Let’s talk cooler nights without the need to sacrifice a full window.
Unlike old-time air conditioners, the modern mainstream floor units sold today use large hoses to vent air while providing very concentrated, effective cooling to spaces spanning between 150 square feet of space and 600 square feet of space.
The benefit of upgrading to a portable air conditioner from a window unit is that you don’t have to deal with the hassle of shoving a clunky box-style air conditioner inside your window frame. What’s more, these units can actually roll from room to room quite easily.
In addition to being more attractive, portable air conditioners are also more efficient. You also don’t necessarily need standard-sized windows to use them the way you do with box units.
Of course, the biggest benefit of all is that you’ll be making a one-time investment to enjoy more cooling power per BTU.
In top place as the quietest portable air conditioner with the best performance is the Black + Decker BPACT12WT Portable Air Conditioner. This AC unit breezes by the competition for its ability to cool a large space so quietly. However, there are many other contenders that fit the bill for cooling down your home without raising your energy bill.
Here’s the list of the quietest portable air conditioner units out there if you’re shopping for a bedroom air conditioner, sunroom air conditioner, office air conditioner or all-around cooling sensation that you can move from room to room.
The Top Eight Quietest Portable Air Conditioners
1. Black + Decker BPACT12WT Portable Air Conditioner
Known for offering the cutting edge in large appliances, BLACK+DECKER outdoes itself with this 12000-BTU portable air conditioner. It’s a fast and efficient pick for small rooms up to 200 square feet.
This unit definitely makes the list if you’re looking for an air conditioner that can be trotted into a dorm, cabin or camper on hot days. This is an easy contender for the title of quietest 12000 BTU portable air conditioner.
Reviewers who have used this unit in their homes and offices praise it for its quiet operation, easy installation and stability. A special 51-decibel sleep mode makes this a very subtle and still cooling companion on hot nights.

2. Honeywell 10000 BTU Smart WiFi Portable Air Conditioner
Using Wi-Fi and voice command, you can instruct this portable air conditioner on exactly what temperature to cool things down to in a room!
With a capacity to cool down 450 square feet of space, it does a good job of mimicking an integrated “smart AC” system. Honeywell really packs in lots of performance features that add peace of mind. The list includes thermal overload protection, dual dust filtration, ETL-certified performance and ISTA-6 certification.
The reason why this Honeywell doesn’t rank first on the list is that not everyone is willing to pay the higher price tag on this unit for the extra tech features. However, the 52-decibel performance of this unit does make it as close to a silent air conditioner as you’ll get in this price range.
Reviewers are quick to comment that this unit is much quieter and cooler than a floor fan. Many remarked that they had no trouble hearing the television when this unit was on.
Lots of reviewers also felt pampered by the voice-command option that allows them to adjust the temperature from the other side of the room.

One reviewer calls this unit “the best portable A/C money can buy.” Reviewers cheer across the board for this unit’s ability to deliver consistent temps for long stretches. Its low noise levels at high speeds also earn it points.
While the unit’s clips and hose earn praise for being sturdy and convenience, some reviewers dislike the fact that the window vent included in the set stays in place on your window even when the unit is put away for the season.

An LED display and remote control make it easy to control this unit from bed.
Reviewers applaud the way this unit puts out so little water while offering consistent cooling. While 55 decibels makes this unit louder than the comparable 8000-BTU Black + Decker model, most reviewers had no problem at all falling asleep with this bedroom air conditioner.
