With the holiday season coming to an end, you might think that it's time to say goodbye to the cooler temperatures outside, but finding the right air conditioner unit for your home can help keep the cool air all year round. 

However, with the many options and choices for air conditioners available these days from window air conditioners to portable air conditioners, you might have a hard time choosing which one to get, especially when you're trying to find one for larger rooms.

Additional Considerations

Before buying an air conditioning unit, it's important that you also consider the following factors before making a decision:


When venturing off to buy large room air conditioners, it's best to accept that these units will be more expensive and will require a bigger initial investment. This is because these air conditioners will need to be more powerful, especially if they come with additional features like smart technology features that support Amazon Alexa and Google Assistant.

Cooling Power

An air conditioner meant to cool larger rooms will naturally need more cooling power. A unit's cooling capacity is measured in British Thermal Units or BTUs, with a higher BTU rating corresponding to a higher cooling power in air conditioners. As a rule of thumb, air conditioners need a 20 BTU rating per square foot of space to keep one room adequately cool.

It's very important to take the coverage area when choosing an air conditioner, but higher isn't always better. Try to avoid air conditioners with too high of a cooling capacity as this might cool an entire room too quickly. Not only will the air conditioner not be able to dehumidify the room as efficiently, but it will also switch on and off too frequently.

Energy Efficiency

Another thing you should keep in mind is that more powerful air conditioning units will require more electricity to run. Air conditioners meant to cool larger rooms will naturally be more costly as these units will be using more power to cover the entire room, as compared to air conditioners built for smaller rooms and require less energy consumption.


Lastly, it helps to be aware that air conditioning units need regular maintenance, such as draining any water accumulation or replacing air filters, to avoid growth of mold and maintain the air quality being circulated in the room.
