In today's day and age, everyone wants to walk into an air conditioned room, regardless of how big or small the space is. However, it might be hard to find the right model for these small spaces, especially when you aren't familiar with the things you need to look for to find the right small room air conditioner.

Here are some things to look out for when shopping for an air conditioning unit, as well as some great recommendations to get you started.

Things to Consider When Buying a Small Air Conditioner

Cooling Power

The cooling capacity of an air conditioner unit is one of the most important factors when wanting to cool down small spaces. The cooling power of air conditioners is most commonly measured in British Thermal Units (BTU), but may also be measured in Horsepower (HP) or KiloWatts (kW). Small rooms typically use AC units with 12,000 BTU or less.

As easy as it is to believe that a higher cooling power is always better, this isn't always true. You should avoid buying an air conditioner with too high of a cooling capacity for a small space as this will not only cause the unit to cool the entire room too quickly, but it could also cause unnecessary stress on the air conditioner by forcing it to switch on and off too frequently.


Air conditioner units cost money to buy and maintain, even when these are small units. This must be something that you probably already thought about and considered, but it bears repeating nonetheless. The price of the unit will depend on the model, but you can expect an average cost of around $2,000 to $10,000.

Energy Consumption

Another aspect that will require you to spend money is the energy consumption needed to run a small air conditioner. While these may consume less electricity compared to larger air conditioners, they will still need power to produce cool air. A way to minimize the financial impact of this is to opt for energy efficient models that aim to reduce energy consumption.

3. Fridgaire Window-Mounted Room Air Conditioner (6,000 BTU)

This very affordable window air conditioner is small but powerful as its 6,000 BTU rating lets it cool down an entire room of up to 250 square feet. Apart from that, this small window air conditioner also comes with a handy remote control for convenience, as well as a built in timer.

4. Black+Decker BD05MWT6 Small Room Window Air Conditioner (5,000 BTU)

A great small window AC unit for small rooms, it can cool a room of up to 200 square feet. It's also a great option for those who care about their environmental impact as this air conditioner uses R32 refrigerant that has no impact on the ozone layer, but still improves the unit's energy efficiency.
