It seems that everyone today is buying an air conditioner for their homes, but it might seem hard to find one that can effectively cool down large spaces. It doesn’t have to be that way because there are many air conditioners available that can take on the challenge.

There are different air conditioners available that come with the needed power to cool down bigger rooms, while also coming with additional features that could make your comfort more achievable. 

Factors to Consider

Cooling Capacity

The air conditioner’s cooling capacity is the most important factor when buying for a new unit as this is what will affect your overall comfort the most. The cooling capacity of a unit refers to how quickly and efficiently it can cool down a room. Higher cooling capacities can cool down bigger rooms, while lower cooling capacities are more suited for smaller rooms.

Most commonly measured in British Thermal Units (BTU), you can easily calculate your cooling capacity needs as a square foot of space requires around 20 BTU. With that being said, an air conditioner with a 15,000 BTU cooling capacity can cool down around 875 sq. ft.

Type of Air Conditioner

There are many types of AC units to choose from. All of them have their benefits and advantages, so it's best to assess the layout of your room to decide which type is the most appropriate for you. The most common types are the window air conditioner, the portable air conditioner and the split system air conditioner.

Price and Cost

Needless to say, getting an air conditioner is going to have an impact on your overall spending. Not only will buying a new unit cost money, but you’ll also have to pay additional electrical costs to keep it running, as well as regular maintenance. Depending on the type of air conditioner you get, you might also have to pay for professional installations.
