How to Choose a Windowless Air Conditioner
Before you invest in a windowless AC there is a certain criteria you need to consider. Here are some of the things that will help you determine which kind of model suits your needs accordingly.
This is the main point to consider when you want to buy a windowless AC because it's the framework that regulates the efficiency of air conditioning. The cooling power of all windowless AC is measured in BTU’s (British Thermal Unit).
The power required will vary depending not only on the size of the room to be refrigerated, but also on other features built-in your home including insulation, sunshine, numbers of openings, and type of ceiling.
Your first task is to measure the size of your room in order to establish the amount of BTUs essential for your space.
- Below 200 sq. feet requires 5,000 to 8,000 BTU units
- Between 200-350 sq. feet requires 10,000 to 12,000 BTU units
- Between 350-500 sq. feet requires 12,000 to 14,000 BTU units
- Above 500 sq. feet requires 15,000 BTU units
In simple terms, the higher the BTUs, the higher the space that can be air-conditioned.
This is another critical point because the windowless AC is an electrical device that operates by consuming a lot of energy. We recommend you find a model that has the least energy consumption rate.
Therefore, look for models with an "Energy Star" rating logo or higher energy efficiency ratio. Generally, a unit with a lower EER rating of five is most definitely consuming more energy than a higher rating of 10 which is more energy efficient.
Remember, to choose a model that is adapted to the size of the space to be cooled since it will consume efficient energy by producing just the required amount of cooling experience.
The noise level of your air conditioner is a factor to consider because nobody desires a unit producing a lot of noise around them.
Recommended noise level ranges are between 55-70 dB for any AC. Above that, the noise may be irritating and disturbing to your eardrums. However, some windowless air conditioners come with a silent or night feature which allows you to enjoy a quiet and cool atmosphere.
In some models in our list, the windowless air conditioner acts as a dehumidifier which eliminates dampness from the surrounding air, providing freshness to the atmosphere.
The dehumidifier capacity is measured in liters per hour.
Not all models have this feature built-in, so it depends whether you need an air purification function in your windowless air conditioner.
Having a model with a thermostat function allows you to run your AC for a selected period. In most cases, a windowless AC with integrated thermostat function automatically switches off when the desired temperature is reached.
This feature is advantageous since you are able to control energy consumption and prevent premature wear over those models without.

Yes, they are perfect AC units depending on your situation. Most of them are portable and you can easily move them around from a room to another as you wish.
How Does a Windowless Air Conditioner Work?
Windowless air conditioners work with the help of three main parts: a compressor, a condenser, and an evaporator. The cooling effect starts when hot air enters the compressor in a gas form. Eventually, gas pressure increases, which forces itself to the condenser.
Once there, the gas cools significantly and leaves the condenser as a liquid. In the evaporator, the liquid turns to gas and takes in heat from the air releasing cooled air to the surrounding. This process continues with the control of the thermostat.
How to Drain Water from a Windowless Air Conditioner?
Follow these steps:
- Find a drain bucket or move the unit close to a sink.
- Find the drain plug either on the side or back of the unit.
- Drain the water by removing the drain plug and stopper.
However, once the drain plug is removed, remember to set up the drainage for continuous drainage.
4. Measure the drain port mouth and get a hose of exact width to ensure a water-tight fit.
5. Place your drain hose in the proper position (downhill) for it to be effective.
6. Note that in order to support continuous drainage gravity must apply.
