Buyer's Guide

Air Conditioner Buyer's Guide

Air conditioners are invaluable during hot weather by providing relief from heat and humidity. By their definition, air conditioners cool, dehumidify, and filter the air passing through them. Most modern air conditioners are efficient and quiet when compared to older models as long as you’ve selected the proper size and type for your living or work space.

Although these appliances have remained relatively simple throughout decades of use, there are still several things to think about when you’re looking to purchase a new unit.

Consider where and how the AC will be installed whether mounted in a window, a portable unit for around the house, or if you’re looking for something more permanent like a central unit. Figure out the size of the space where the air conditioner will be installed as this will determine the BTUs needed to effectively cool the space. Think about if you’re going to be installing the unit or if your budget will cover both the AC unit and any potential professional installation costs. Finally, reflect on any features you’d find useful to have.

AC Size

Cooling power is measured in British thermal units (BTUs) per hour. Choosing the right amount of BTUs is important to ensure the best performance and cooling efficiency. If the air conditioner is too small, it won’t cool the room sufficiently and use up more energy. On the other hand, if it’s too large, the compressor may switch on and off; this doesn’t lower humidity effectively, resulting in a cold yet humid room.

To ensure you pick the right size, it’s important to first measure the square footage of your room. Do this by multiplying the length by the width. As a general guideline, 5,000 BTU will work for a room of up to about 150 square feet, whereas 10,000 BTU will work for a room of up to about 500 square feet.

Remember, this scale isn’t linear so refer to a complete list of recommended sizes for your space. This may also change if the room has an exceptionally large amount of sunlight, or if you’re planning on installing the AC in the kitchen; both environments may require additional BTUs for adequate performance. Also consider the age of your home as well as your local climate.

Although there are several types of air conditioners, we’ve focused on the two most common types.

Window AC
Thanks to their availability, relative efficiency, and generally affordable pricing, window air conditioners are by far the most common type of AC unit. They can usually be installed easily and come with a wide range of features. A drawback with these units is they obstruct part of the window and tend to be a bit noisy. They also need to be removed or winterized during colder months.

If you’re planning on installing a window AC, begin by verifying the type of window you have; there are models that will work both with standard windows and slider/casement windows. Measure the width, height, and depth of your window. Be sure to do this more than once just to be absolutely certain of your measurements.

Portable AC
These are freestanding air conditioners which don’t require permanent installation and typically have caster wheels so they’re easy to move around. These characteristics make them an excellent choice for those who don’t need to use the AC as much or who have multiple rooms which need cooling but don’t want the hassle of installing a unit. Many portable units have a window venting kit for a hot air exhaust hose.

The convenience of room-to-room portability does come with some drawbacks. While some units use evaporation or hookups for a drainage hose, most use a water reservoir which needs to be emptied on a regular basis. Because of this, be sure the reservoir is easy to access as well as large enough to avoid frequent emptying. Portable air conditioners also tend to be less efficient than window models, but nonetheless remain more efficient than older style air conditioners.

Efficiency Rating Terminology

Energy Efficiency Rating (EER)
This refers to how many BTUs are used per hour for each watt of power. The higher the EER rating, the more efficiently your new air conditioner will operate. Air conditioners with a high EER tend to be more expensive, but will be cheaper to run over time.

Seasonal Energy Efficiency Rating (SEER)
This relates primarily to central and ductless air conditioners. AC Units sold in the US must have a rating of at least ten.

Energy Star
Products with an Energy Star rating meet stringent government standards for efficiency.


Most AC units feature practical applications for increasing efficiency and convenience.

Adjustable Airflow Direction
Most air conditioners have the ability to direct airflow, but if your air conditioner will be installed in a location where this is especially important, be sure to verify that this feature is included.

Some air conditioners also include a dehumidifying-only mode, a fan-only mode, and even the ability to produce heat. These can be very useful to have, and expand the utility of your air conditioner.

Some air conditioners have timers or energy savings modes to allow for efficient and relatively hands-free operation.

Regardless of the size or features, ensure that the air conditioner you choose has easy-to-use controls. Some units now have intuitive digital displays and temperature readouts.

Although most major brand names offer good warranties, it’s well worth your time to check what type of manufacturer’s warranty, if any, is offered.
