How To Choose The Right Air Conditioning System

May 6th 2015 at 12:17 AM

Having a high-quality air conditioning unit in place can help you stay cool and comfortable throughout the summer, even during an extended heat wave. However, selecting the best unit for your needs can be tricky, especially if money is a concern.

If you buy a unit that is too small for your needs, you will have a hard time cooling down your home, and the unit itself will be under a great deal of strain. However, if you buy a unit that is more powerful than you need, you will waste a lot of energy. You need to take the time to properly size the unit by determining your cooling needs.


In most cases, the capacity you will need is determined by how many square feet need to be cooled. This can also be affected by how much direct sunlight parts of your home get. The more sun exposure you have, the more powerful of an air conditioner you will need.

You will also need to decide whether you want to rely on window air conditioners that cool each room individually, or if a central air conditioning system would be a better choice. In a small home that is well-shaded from the sun, or in a climate that does not tend to experience long heat waves, window units may be a more practical choice.

However, if you have a larger home with a lot of sun exposure, or if you live in an area that tends to endure long hot spells, a central unit is often the best choice. This way, you can make sure that your whole home stays cool no matter what the temperature outside may be.

In addition, there are also portable air conditioners that can be moved from room to room. These are larger and more unwieldy than window air conditioners, however, but they also have a greater cooling capacity. They do need to be attached to an outside vent or window to remove the hot air from your home.

Most air conditioners are rated by BTUs, or British Thermal Units. This measurement basically determines how quickly a unit can cool down a room once it starts running. The more BTUs, the more quickly it will cool things down. Most air conditioners range between 5,000 BTUs and 20,000 or more.


The amount of shade that you get and the number of people who live in your home will also affect your needs. A well-shaded home can decrease your cooling requirements by around 10 percent, and a particularly sunny home will increase them by the same amount. For every person who lives in your house, add 600 BTUs. In addition, your kitchen will require an extra 4,000 BTUs.


By taking all of these factors into consideration, you can make sure that you choose an air conditioning system that is properly sized to meet your needs. This way, you can make sure that you cool your home as quickly and efficiently as possible.
