The modern air conditioners are capable of beating the heat but come at a high price. While many people can afford high-end air conditioning systems to keep their homes comfortable, not everyone has the means. Window conditioners are an affordable, efficient option for those with limited budgets. If you only need to install a window AC unit, and you want to achieve the maximum cooling effect, then you should get the largest unit. For large rooms, window AC units can cool places up to 1,500 sq ft. But what model should you buy? Before we go on to our list with the top window AC units that can be used in large rooms, please read this buying guide.
BTU, or tons, is used to measure the size of an air conditioner. Window conditioners are available in sizes from 5,000 BTU to 24,000+BTU. A window AC unit that produces more than 15,000 BTU is considered for large room. You can still use 110V units up to 15,000 BTU, beyond that you will need 230V voltage. It is simple to determine which type of window air conditioner you need. Simply look all the big 20,000+BTU windows AC units available in the market, then rank them according to their cooling capacities. We did exactly that. Below is a list of large-sized window AC units for large rooms.
How to Choose the Best Window Air Conditioner ?
Before you make a purchase, it is important to evaluate the various specifications and features of the large room window air conditioner. You’ll be able to determine if the unit is right for you or not.
Cooling Capacity In BTUs
You should first check the cooling power of window air conditioner. BTUs are the unit that measures how much cooling window conditioners provide. Keep remember the cooler the air conditioner is, the higher its BTUs are. If the BTUs are lower than necessary for large rooms, the AC will work harder to cool down. If the AC window has a very high BTU rating relative to your room’s size, it will not remove humidity effectively. To find the best model, you need to consider the area of your room.
Coverage Area Size
Another important thing is to consider the area that the AC unit will cover. A small AC unit will not cool your room at the optimal level, but it will also consume more electricity. You’ll end up paying more for energy and less cooling. The coverage area of an air conditioner system is something that most brands will mention in product box. A 15,000 BTUs air conditioner is recommended for rooms that are medium-to large in size.
Energy Star Certifications
Energy efficiency is another important aspect to consider when selecting the best window AC unit with highest BTU. You don’t want your monthly cooling bill to be high. Energy Star certification is a way to ensure that your air conditioning system is efficient. This label will ensure that units use approximately 10% less energy than their counterparts.
