Now that you know the best 14 portable air conditioners, here are a few factors to consider before buying the right one.

How To Choose Portable Air Conditioners – Buying Guide

  • Size

Portable air conditioners are small and offer better mobility. The BTU level determines the size of the AC unit, and for choosing the right size, compare the BTU level with the size of your room.

  • Weight

A compact and small-sized AC unit will be lightweight. Portable air conditioners weigh up to 60 lbs. However, weight is not a huge concern in AC units with 360-degree rolling wheels as you can move it around easily.

  • Dehumidifier And Heating

Most of the portable air conditioners come with built-in dehumidifiers. Dehumidifiers collect the humidity in the room and evaporate it outdoors, keeping the room dry and cool. You can choose an AC unit that has a dehumidifying capacity of up to 80-90 pints a day.

  • Energy Efficiency (Power Consumption)

If you are concerned about the power consumption of the device, consider the Energy Efficiency Ratio (EER) of the product. Devices with higher EER are more energy-efficient and consume less power.

  • Noise Level

Most portable air conditioners will cause a little noise as they are entirely inside your home, unlike the window units. However, if you are looking for a device with a low noise level, pick one that generates less than 48 dB noise.

  • Water Drainage System

For some air conditioners, you have to drain the water bucket and dispose of the water manually. Some devices come with a drain hose that lets the water drain from the unit easily. You can also attach a condensate pump to collect the moisture. However, some models evaporate the humidity outside quickly, so no drainage is required.

  • Choosing The Right BTU Level

The British Thermal Unit (BTU) reflects the amount of heat an air conditioner can remove from your room. A higher number means it offers more cooling power. Thus, for selecting the best air conditioner, compare the BTU with your room size. Here is a chart you can follow:

  • 8,000 BTU for up to 200 sq. ft.
  • 10,000 BTU for up to 300 sq. ft.
  • 12,000 BTU for up to 400 sq. ft.
  • 13,000 BTU for up to 450-500 sq. ft.
  • Dust Filtration

Some portable air conditioners come with washable side filters to trap dust and hair and prevent dirt from entering the unit. You need to clean the filters regularly for using the unit.

  • Venting System

Ventilation is a crucial factor to consider as portable air conditioners vent out the hot air and circulate cold air. For proper ventilation, place the unit near a window. Most of the devices come with a window kit and an instruction manual to set the unit properly for ventilation. You can also buy an extension hose for better ventilation.

  • Timer Function

The timer function is provided in all the portable air conditioners. You can start and stop cooling for a certain amount of time using this feature.

  • Adjustable Airflow

You can adjust and control the airflow by choosing the appropriate controls on the device. Switch between fan, cooling, and dehumidifying modes for increasing or decreasing the airflow.

  • Installing

The portable air conditioners are easy to install. Consider setting up the window kit for better ventilation. Refer to the instruction manual and install the vent in the window. You can also purchase an extra vent kit if you are likely to use the unit in different rooms.

  • Remote Control

You can operate and change modes of the unit from a distance using the remote control. It is more convenient to change the settings with remote control.

  • Single-hose Or Double-hose

A single-hose air conditioner works by taking hot air from your room, cooling it, and circulating it around the room. The excess hot air is vented out the window through the venting hose. On the other hand, the dual hose systems pull fresh air from outside through windows, cool it, and circulate it in the room. If you want a portable unit, make sure it has a proper window venting unit.

Your air conditioner needs proper cleaning. Follow these steps to clean the unit at home.

How To Clean A Portable Air Conditioner

  • Drain the water and run the fan mode to dry the unit before opening it.
  • Remove the screws and store them carefully.
  • Remove the dust from the condenser using a cloth or aluminium fins. Also, clean the dirt from filters or wash the filters if they are washable.
  • Vacuum the air intake vents if they are dusty. Clean the cooling coils and external housing units with a cloth and non-acidic cleaning solutions.
  • Reassemble the housing and fasten the screws.
  • The unit will throw fresh and cooler air immediately.

A portable air conditioner is versatile and can be transported between rooms. They are more cost-effective than central air conditioners for single rooms. Choosing the right unit can be tough from plenty of options available online. Our list of the 14 best portable air conditioners will guide you to reach the best one. Pick one and chill in your room!
