Portable Air Conditioner for a Small Room – Buyer’s Guide
Knowing what to look for with your portable air conditioner can remove some of the stress that comes with picking one. Since this can be a decent investment, we want you to be sure you’re making a great choice that you can use for years to come.
For home units, the prices generally range from $150 to over $800. You don’t want to break your budget, so do your research. You can get a high-quality portable air conditioner for a few hundred dollars. You have to think of it as an investment because it’ll last you for years with proper care. This durability makes it well worth paying a little more for it upfront.
When you use your portable air conditioner, you may see a jump in how much energy you use per month. While it’s not completely unavoidable, you can take steps to lower it. For example, look for a portable air conditioner with an energy star rating. These models are more energy-efficient.
This rating means they use less energy to run, and you can run them for longer without raising your energy bill. Additionally, you can run your air conditioner in the morning and evening hours to help beat the heat. Finally, close your blinds during the hottest part of the day to keep the cool air in.
How big is the room you want to cool? Manufacturers measure room sizes in square feet and BTUs. The lower the BTU rating on your air conditioner is, the smaller area it’ll be able to effectively cool. The goal is to find the BTU rating that matches the room or rooms you want it to work in, and the following chart can help:
|Room Size||BTU Rating|
|150 Square Feet||5000 BTUs|
|250 Square Feet||6000 BTUs|
|300 Square Feet||7000 BTUs|
|350 Square Feet||8000 BTUs|
|400 Square Feet||9000 BTUs|
|450 Square Feet||10000 BTUs|
|550 Square Feet||12000 BTUs|
|700 Square Feet||14000 BTUs|
|1000 Square Feet||18000 BTUs|
|1200 Square Feet||21000 BTUs|
|1400 Square Feet||23000 BTUs|
|1600 Square Feet||25000 BTUs|
|1900 Square Feet||28000 BTUs|
|2700 Square Feet||36000 BTUs|
Unlike a regular window air conditioner, most are taller than they are wide or long. They look very similar to a dehumidifier and are usually no taller than 3 feet, are less than 2 feet wide, and around one foot long. They are usually tower-shaped, but some are designed with curves to look more appealing.
Usually, most air conditioners have controls on their face, but many portable models can also come with remote controls that you can use from several feet away. There are even some models that can be controlled through an app on your phone, but these are a little more difficult to find, especially affordable ones.
If there are no special features that come with the air conditioner that you are looking at, you can probably expect to only wipe it down to remove any dust or dirt when it comes to regular maintenance. You will also need to check, clean, and/or change the filter on a monthly, bi-monthly, or around every 4 months depending on the model, size, and how often you are running the unit.
Dual-hose vs single-hose
Portable air conditioners have hoses that are put through a window, and this hose is what helps to ventilate the unit. Some models have single hoses, which are usually more affordable, and others have 2 hoses, which are usually more efficient but expensive. Single-hose units are also usually easier to find when compared to the dual-hose units.
- The Most Energy Efficient Split System Air Conditioner
- The Most Energy Efficient Inverter Air Conditioner
Usually, the larger the unit, the more noise it will make. Some of the higher-end units come with a silent or quiet mode, which can be more convenient at night whether you have sensitive neighbors or you have trouble falling asleep to the regular hum when the unit is on its normal settings.
If it does not come with this special setting, you can expect it to be about as loud as a normal air conditioner if not maybe slightly quieter.
Some of these units can come with extra features like a heater, an air filter, or even a built-in dehumidifier. These can be a bit harder to find and are usually more expensive, but they can be more cost-efficient. It can also save you space as opposed to getting an air conditioner and another device, which is almost necessary if you live in a smaller-sized apartment.
Units that have a special feature may need more attention than a regular one. Those with built-in dehumidifiers will need the tank emptied whenever it gets full, which may be every few days to every few hours depending on how humid it is where you live. Those with air filters or a heating function will require the filter being cleaned and/or changed frequently to avoid damage to the unit and even a possible fire.
The Best Portable Air Conditioners for a Small Room – Reviews
1) MIDEA MPF08CR81-E Portable Air Conditioner
Special Features: Sleep Mode, Eco timer, Reusable and Washable Filter
This unit is one of the more shapely models that has its controls on the top, air vents in the front, and hose in the back. It is a single-hose model, and it is about 30 inches tall, 18 inches wide, and 15 inches deep.
This is also a unit that has a built-in dehumidifier, too, but it does not say exactly how much water it can store. It also has a neat feature where if you do not want to use the hose, the unit can store the water it would normally filter out through the hose into the tank, but it does need to be emptied often. The setting can also be a bit difficult and temperamental every now and then, too.
This unit does come in 4 different sizes: 8,000, 10,000, 12,000, and 14,000 BTUs. Nearly every size is also available with or without a Wifi connection that allows you to control the unit with your phone or other smart devices, which is pretty convenient if you forget to turn it off and you are busy in another room.
It seems to be one of the more convenient models, especially with all of the settings it has. It has a built-in timer, swivel function, several fan speeds, special modes, and even a filter light that lets you know when the filter needs to be changed. The one downside to this model is that the hose that it comes with seems fairly frail and easily breakable, especially when it gets cold, meaning you probably will not be able to use it all year long and should put it in a place where the hose will not be bumped or run into.
2) LG LP0817WSR Portable Air Conditioner
Special Features: Auto evaporation system, Auto-swing air vent technology, Programmable 24-hour on/off timer
This unit looks similar to the previous one, but instead of being shapely and defined, this one has a more square and simplified look; it looks very similar to a standard dehumidifier. It is about the same size as the last model but is a bit shorter since it is around 24 inches tall and wider since it is around 19 inches wide, and it is one inch deeper, also.
This model also has a built-in dehumidifier, and its tank can draw in nearly a quarter of a gallon per hour; the exact size of the tank is unknown. Like the last model, it also has a swivel function.
Unlike the last model, this unit’s controls are a bit more basic, only having 4 different fan speeds and 3 different modes: cool, dry, and fan. It does come with a remote that has all of the on-face controls along with the swivel function, too. The remote seems to have a distance limit of around 15 feet or so, and it can be a little tricky unless you are pointing it straight at the unit.
This unit does seem a little louder than the previous one, possibly because there is no quiet mode like the other model, but it does seem to blow out cool air nearly just as fast. The biggest downside is that the tank can fill up fairly quickly, just as quickly as the last model if not a little sooner.
