What Are Energy-Efficient Air Conditioners?

Energy-efficient air conditioners cool your home using less energy than regular models, making them more affordable and better for the environment. An air conditioner’s SEER (seasonal energy efficiency ratio) rating shows how much energy it uses to cool an area, and a rating of 13 or higher is standard on today’s energy-efficient models. Replacing your old air conditioner with a newer, energy-efficient model could reduce your cooling costs by 20 to 40 percent. Some models even have fan-only options for nighttime use, or lights that notify you when it’s time to change the filter.

How Do Portable Air Conditioners Work?

Portable air conditioners are easily movable devices that either evaporate or refrigerate air to cool a room or small space. Their power levels range from 5,000 to 60,000 BTU (British thermal units), with 7,500 to 14,000 being the most common levels needed to cool a normal-sized room. Portable air conditioners typically sit on the floor, but some models can be mounted to a window to redirect heat outside. Depending on the model, you may need to empty the unit, as they remove moisture from the air to cool it.

What Are the Benefits of Central Air Conditioning?

Central air conditioning is beneficial because a single unit cools the entire home at once. Units typically range from 5,000 BTU (British thermal units) to 34,000; the larger your home, the more BTU you’ll need to cool the house. Unlike window or portable air conditioners, a central air conditioning unit cools the whole house and allows you to set a specific temperature. Because central air units are located outside the home, they’re typically quieter and more visually appealing than window air conditioners.

What Is a Mini-Split?

A mini-split, also sometimes called a ductless air conditioner, gives you the comfort of a local air conditioning unit without the extra bulk and hassle. It is so called because it splits the parts of the air conditioner between the inside and the outside of your home: The blower is on the inside wall of your room, while the compressor and condenser stay outside and out of hearing range.

What is the Right Air Conditioner Size for My Room?

The size of the air conditioner you need is based on the size of the rooms you want to cool, the type of rooms you want to cool and how many people live in the house. The actual air conditioner size isn’t what’s important; the air conditioner BTU (British thermal units) rating is what determines the actual output of the air conditioner. Measure your room before buying a unit to figure out what size you’ll need. For example, 14,000 BTU cools 550 to 700 square feet.
