7. KwiKool 18,000 BTU Portable Air Conditioner

AC Type Portable Air Conditioner
EER Not Energy Star Certified
Voltage 115V
Weight 205 pounds
Warranty 1 year limited

Made in the US, this 18000 BTU portable AC is ideal for cooling server rooms and industrial spaces, especially in places where extra heat is generated by electrical equipment.

With it being able to cool rooms of around 600 sq. feet, the KwiKool KIB1811 is one of the best portable air conditioners of 18000 BTU out there.

It is among the heavy-duty models with an internal pump for constant operations, simple controls, and a big condensate tank.

However, unlike the easy-installation feature accompanying other models, this unit requires a ceiling vent kit for proper installation.

The KwiKool has a heavy-duty construction with a hammer-coat protective finish; its galvanized and insulated cabinet allows maximum efficiency, durability, and quieter operations.

Furthermore, its big, locking casters makes installation easier. And it comes equipped with internal overload circuitry that prevents this unit from overheating during operation.

The pressure switches cut off operation when the temperature gets too low or high. Because of this, your 18000 BTU portable AC does not mean overwork and prevents any operation problems.

This air conditioning unit is also equipped with an internal pump for constant operations. You just have to use the internal condensate pump to remove moisture away from the unit into the tank.

Additionally, it has control board notices and alarms that tell you when the tank is filled, automatically stopping the operation.

The KwiKool Portable air conditioner plugs into a 115V outlet, and the adjustable vents can be adjusted where needed.

Another defining feature of this model is that it does not have any negative air pressure. Many portable air conditioners produce negative air pressure when they cool since they use the same internal air to cool the unit while cooling the room.

But with KwiKool, you can avoid the problem by getting a two-way ceiling duct kit to cool the unit.

What We Like
  • Can cool a room of around 600 sq. feet
  • Suitable for cooling heavy equipment rooms like server rooms
  • Has a two-way ceiling duct kit to cool the ceiling
  • Internal overload circuitry stops the unit from overheating

When Are 18000 BTU AC Units the Right Choice?

Your typical air conditioning unit comes with a BTU (British Thermal Unit) rating. The bigger your room size is, the greater BTU your air conditioning unit should have.

Small rooms like ones lower than 150 sq. feet need a unit with almost 6000 BTU – ideal for single bedrooms.

At the same time, larger rooms of around 350 sq. feet (most living rooms) require a unit with 9000 or even 10, 000 BTU.

Huge rooms – such as ones bigger than 700 sq. feet – require an air conditioning unit with the BTU range of around 18000 BTU, and they will cool the room much faster than your typical lower BTU units.

Factors To Consider When Buying an 18000 BTU Air Conditioner

Before you choose the best 18000 BTU air conditioner, consider the various factors to help you better choose the suitable air conditioning unit according to your needs:

Coverage Area

When selecting an 18000 BTU air conditioning unit, it is crucial to understand your coverage area requirements.

Therefore, you should know the size of your house, office, server room, or any room you will be using the air conditioning unit in.

Noise Levels

A typical conversation happens at 60 dB. Therefore, you will need an air conditioning unit with lower noise than that.

With that said, units with 55 dB or lower are preferable; the ideal noise level should be closer to 15 decibels.

Energy Efficiency Rating (EER)

It is generally known as Energy Efficiency Rating, and it provides you an understanding of the amount of cooling capacity provided by the unit via energy used.

Typically, the higher the EER, the lower the energy costs. Hence, it would help if you were mindful of this before investing.

Performance Features

There are various performance features you must look for when selecting the best 18000 BTU air conditioner.

This includes:

  • Auto setting
  • Timer setting
  • Heat mode
  • Multiple fan speeds
  • Sleep mode
  • Dehumidifier

Most newer models have all these features, but fan speeds vary, and specific models do not have dehumidifiers.

Installation Requirements

Many window air conditioning units have been designed so that they fit inside your typical double-hung windows.

Nevertheless, most unit models can be installed inside any custom-created wall space via special mounting hardware.

These are ideal if you have too large or too small window dimensions or do not have vertical sash windows.

Voltage Requirements

Another feature to look for when selecting the best 18000 BTU air conditioner is the voltage requirements.

If your home only has 220V and you get a unit that requires 240V, it won’t do you any good. So ensure that the unit’s voltage requirements meet your house as well.

Price & Warranty

Another factor to consider when buying an air conditioner of 18000 BTU is the price and warranty.

Typically 18000 BTU units have a one-year limited warranty, and prices vary from 900 USD to 3000 USD based on the model features.

18000 BTU Window AC Vs. Portable AC

An advantage of portable air conditioner has over its window counterpart is that it has higher flexibility options.

It can be moved easily from window to window if you are looking to cool various rooms. Not only that, you can easily install it through the door via an extended installation kit.

Even though window air conditioners cannot easily be shifted from one room to another, they are much more energy-efficient.

This means that you get much more cooling power per BTU, so if you are using an AC window unit of 18000 BTU, you will have much more cooling than an 18000 BTU portable AC.

People Also Ask (FAQ)

How much electricity does an 18000 BTU air conditioner use?

Electricity usage depends on the EER of an 18000 BTU unit as well, but it typically ranges from 4500-5200 watts per hour.

How many watts does an 18000 BTU air conditioner use?

It uses around 1800 Watts.

How fast does the 18000 BTU air conditioner cool the room?

An 18000 BTU AC can cool a maximum area of 1000 sq. feet, and it takes around 3 hours to cool that area. But depending on the room’s size, it can take less as well.

Conclusion

Various models offer 18000 BTUs. And that includes portable and window air conditioning units.

Moreover, window air conditioning units are much more energy efficient in regards to their BTU, so if you do not have to shift your AC from time to time, they might be the ideal option.
