How Much Space Does a 14000 Btu Air Conditioner Cool?

A 14,000 BTU air conditioner will adequately cool a room that is about 500 square feet in size. This is assuming that the room you are cooling has a standard ceiling height of 8 feet. If the ceiling’s height is higher, you will have a larger amount of air that needs to be cooled. As a result, you may need an air conditioner that has a higher BTU rating than 14,000.

Similarly, it is assumed that the environmental conditions are not extreme. If the temperatures are abnormally high, you will need additional BTUs to cool the room adequately.

Therefore, the estimation that you need a portable air conditioner with a rating of 14,000 BTUs to sufficiently cool the air in a room that measures 500 square feet is based on several assumptions.

You need to choose an air conditioner whose BTU rating matches your room’s size. If you use a device that has a low rating, you will not get the right service. Your air conditioner will have to run non-stop but still fail to cool the air adequately.

If you use an air conditioner with a very high BTU rating, you will have to pay more for power than you genuinely need. The excess capacity of the air conditioner will go to waste.

How much electricity does a 14000 BTU air conditioner use?

A 14,000 BTU portable air conditioner uses about 4.1kWh of electricity. This figure is based on a formula for converting BTUs, the rating of air conditioners, to kWh, which is the unit of measuring electric energy. A standard portable air conditioner with a BTU rating of 7,500 will consume about 2.2kWh of electricity.

To determine the actual cost of running a 14,000 BTU portable air conditioner, you need to consider two things: the unit cost of electricity and the number of hours the air conditioner runs.

Assume that the cost of a kWh is 10 cents and that you run your air conditioner for 10 hours a day, the cost of operating the device would be $10. You can multiply this by the number of days you run your air conditioner per month to determine the monthly cost.

Other Things to Look for When Buying a Portable Air Conditioner?

Portable air conditioners are the best option for cooling the air in rooms with access to a central air conditioning system. They instantly cool the air in rooms and apartments, thus creating and maintaining perfect air conditions in indoor spaces.

It would be best to make the right choice when buying an air conditioner to enjoy all these benefits. Here are a few essential things that you should consider when purchasing a portable air conditioner.

1. Noise Level

Air conditioners produce a noise level as they cool the air in the room and channel the hot air outside the building. However, the noise level that the devices produce varies with the models, design, and sizes.

The loudest air conditioners have dB levels of over 80. It would help if you avoided such devices because they will cause a lot of distractions when running. The best air conditioners are those which have a noise level of less than 30dB. They are ultra-silent and ideal for homes and offices where ultimate silence is critical.

2. Control Features

Go for portable air conditioners with the most advanced control features, including remote, digital displays, and timers. It is more convenient to use such portable air conditioners than those that lack such advanced control features.

Additionally, some air conditioners have other inbuilt features, including washable air filters, multiple fan speeds, and directional air control. These features enhance the device’s overall performance and let you tune the air conditioner to work according to your needs.

3. Method of Draining Condensate

Air conditioners have pans for collecting humidity, which condenses into water. The device removes humidity from the air as part of the process of cooling.

The method of removing the condensed water from the air conditioner determines how much time you will spend on the device to keep it in perfect condition.

The best air conditioners have full self-evaporative technology. Such an air conditioner effectively dissipates the air’s collected moisture instead of letting it accumulate inside a pan. Other air conditioners have pans that collect the condensate over time.

You can empty the pan by using a pump, which is a separate accessory. Alternatively, you can connect a drain hose to effectively remote the condensate from your air conditioner.

Portable Air Conditioner Tips and Tricks

Although air conditioners can effectively cool the air in small indoor spaces, they are not as efficient as conventional central air conditioning systems.

Nevertheless, you can get the best from your portable air conditioner if you use the best practices.

Here are a few tips and tricks to help you get the best from your portable air conditioner.

  • Switch it on early. Your air conditioner can sufficiently cool the air in your room if you switch it on early before the temperature peaks. If you target to avoid the high temperatures that start at noon during the day, switch on your portable air conditioner a few hours before noon. Doing this lets your device sufficiently cool the air and maintain the temperature even before the outdoor and indoor temperature rises to the maximum levels.
  • Keep the doors and windows closed. If possible, keep the doors and windows closed to get the best service from your air conditioner. When the room is adequately insulated, the air conditioner works best. This is because it does not have to repeatedly deal with huge amounts of hot air that keep on flowing inside a room that is not adequately insulated or one that has all the doors and windows wide open.
  • Take good care of the filters. It is a good idea to buy additional packs of filters for your air conditioner. The extra filters will help you keep your air conditioner in perfect shape always. Remember to replace the filters of your air conditioner every three months.
  • Think creatively about venting. Contrary to popular belief, you can vent your air conditioner in various ways and not solely through a window. The chimney, the roof, and even the floor are some of the viable options for venting your air conditioner. The widow kit that is included in most brands of air conditioners is easy to install and manage. You can even use it to vent the hot air from your air conditioner to a separate room in your house.
