When it comes to cooling a home of 2,000 square feet, the typical recommendation from an expert's perspective is to install a central air conditioning unit of 3 tons or 36,000 BTUs. This size is usually sufficient for a house of this size, however, the larger the system, the more expensive it will be. On the other hand, window air conditioners usually have a cooling capacity ranging from 5,000 to 12,500 BTUs. To determine the size you need for your window unit, you'll need to calculate the square footage of the room where it will be installed. It's important to remember that you should also include the square footage of any rooms that are connected without a door, as the window air conditioner will cool those areas as well.
Additionally, when selecting an air conditioner for your home, it is important to consider other factors such as energy efficiency and noise level. It is also important to consider the climate in your area and how often you plan on using your air conditioner. When selecting an air conditioner for your home, it is important to consult with an expert who can help you determine the best size and type of air conditioner for your needs. An expert can also help you determine the best location for your air conditioner and provide advice on how to maintain it properly. With proper maintenance and installation, your air conditioner can provide years of reliable cooling.
