Product specifications are for reference only. Actual specifications may differ or change from time to time.

*In October 2017, the Department of Energy implemented a new testing procedure which takes different factors into account and generates a lower BTU rating of portable air conditioners to indicate capacity. However, the actual capacity has not changed – the difference is simply due to the different testing procedure. There have been no internal changes to these units, and the functionality remains the same. Please refer to room size guidelines to find the portable air conditioner that best meets your needs. Please also refer to the AHAM website.

**Cooling area coverage can be affected by environment conditions. E.G.: Poorly insulated windows and doors, more sunlight or more heated appliances in the room will be slower to cool down than a room shaded from sunlight or without heated appliances. Check the Cooling Guide for more tips on this.

FAQS
What’s the difference between a portable air conditioner unit and other types of air conditioners?
The basic difference between a portable air conditioner unit and other types of air conditioners is that portable ACs do not require permanent installation and can be moved from one room to the other. Portable ACs can be a less costly investment compared to window ACs as you can purchase one instead of needing multiple units for each room. Window ACs are also fixed and cannot be moved, so there is no flexibility in using them to cool different rooms.
Compared to central air conditioning, portable ACs help save energy as you can cool only the rooms you need, whereas central air conditioning is set up to cool an entire home or building. Central AC is also a much more costly investment to purchase and install compared to portable ACs.
How can I figure out the correct portable air conditioner for my room size?
The most important consideration is the unit’s BTU (British Therma Unit) rating. The larger the room, the higher the BTU requirement. Below are some general guidelines:
Square Footage -> BTU Rating (ASHRAE)
250-350 -> 8,000
350-450 -> 10,000
450-550 ->12,000
550-700 -> 14,000
Remember to consider factors that can affect the number of BTUs required to cool your space, including number of windows, level of insulation, presence of heat-producing appliances, ceiling height, and number of people occupying the space.
What is the best place in my house for a portable air conditioner?
The best part about buying a portable room air conditioner is that it can be used nearly anywhere in your home. All you need is a power outlet and a nearby window to expel warm air in cooling mode (or cool air in heating mode) outside the house. Just follow the instructions to install the window kit, and you will be set in no time. Honeywell Portable Air Conditioners come with a window kit that allows you to easily install the window parts, including the exhaust hose that funnels warm air outside in cooling mode and cool air outside in heating* mode.
*For models with heating mode function.

Powerfull unit, but lacking features
First off let me just say this unit is a beast, extremely powerful and efficient. It can cool most rooms down very quickly and heat them fast too.The downsides though are that the unit isn't very smart, coming from a Hisense ac unit prior, this unit is extremely basic. The deck lid is manual, the remote is mehhh because sometimes it takes multiple button presses to work and doesn't tell you the temp. Also and this is a major one, the unit is extremely bright. The light it puts out is insane. And it has no dimming feature. I'd recommend putting some tint over the lights.Other than that it seems built very well and has cooled rooms with temps over 100°f outside and heated rooms at -15 outside.Overall a good unit

Looove this!
I wasn't thrilled when my husband wanted to buy this unit because of the price but I'm so glad we did. It blows super cold air and cools the room perfectly! Highly recommended!

Solid performance so far
This unit has performed well as a bedroom unit through the summer. The remote is basic, but functional. The iconography on the modes is a bit challenging to differentiate between at a glance. All of that said, it cooled our room all summer.One of my concerns when I was looking at this unit was the water drain. We live in a costal area with moderately high humidity. We have only drained the unit twice. Once because it was full and the second time when cleaning the filters etc.

5.0 out of 5 stars Works as advertised
I just got this today. There's a heat wave here, so I was a bit impatient when setting it up, so installation took a bit longer than I expected. I'm very impressed by how well this cools my bedroom down. It's loud, but I've owned fans that were louder. In fact, the fan I was using was just as loud on high.
