Air Conditioner Buying Guide

A comprehensive air conditioner guide that will give you all the information you need on how to buy a new air conditioner.


Getting Started

Take the edge off of smoldering summer heat with an air conditioner perfectly fit to your space. This buying guide is your complete reference for anything and everything air conditioner. BTUs, voltage, styles, and modern features are covered in detail so you can make sure pick out the right air conditioner for you and your home.

Size

Picking the right air conditioner with the right BTUs is both cost effective and energy efficient. Problems can occur if the air conditioner is oversized for the space or too small for your area. The more cold air that comes out – the more area it needs to circulate to avoid giving the thermostat a false reading. If your AC is too big, the cold air bounces off the walls, back onto itself giving the thermostat a false reading. This will cause the compressor to shut off and not removing enough moisture from the air leaving the room cold and clammy.

First, determine the square footage of the room (multiply length x width).  Below is a handy chart that will help you find the right size room air conditioner to meet your needs.

Types

Casement Air Conditioners
For windows that swing out to the left or right (usually with a hand crank).


Portable Air Conditioners
Can be used in a windowless office or room, although a room with a window is recommended for venting. These can be used in any room, but they must be ventilated so that the exhaust can go somewhere outside of the room.
Wall Air Conditioners
These are installed through the wall of a building and require a sleeve. Sleeves are sold separately and can be found in the air conditioner accessories category.
Window Air Conditioners
For windows that slide up and down.  This AC is installed to take in outside air, filter it, and release cold air into your home.  Accessories can be purchased to assist in ensuring a perfect fit for any window.

Features

They also have convenient features like digital displays, built-in timers, and remote controls. Some units have touchpad controls, and a few even change the direction of the airflow automatically to better disperse cool air throughout the room. Some of the following are features to consider.
Ability to Direct Air Flow
Air conditioners generally have levers you can adjust to direct airflow vertically or horizontally. But most are better at directing air toward one side or the other. Consider your room layout, and look for a model that can direct the airflow where you need it.
Controls

Poorly designed controls are a constant annoyance. Touchpads with large LED displays, large and distinguished buttons, clear labeling, and digital temperature readouts are easier to use. Instead of the traditional bathtub-like "warm" and "cold" controls, the digital age of appliances gives us accurate digital read outs and percise control - down to the tenth of a a degree. Some high-end models can also be connected to a home wireless network, and controlled on a mobile iPhone or Android application. You can control the thermostat while on vacation, in the office, or in the air to make the most efficient use of your home's energy.

What's my plug type or how many volts I need?
Your plug type will let you know how many volts you need. You can compare your outlet to see how many volts you need and also what type of plug your air conditioner requires.  Below is a chart signifying what the plug will look like and its electrical information.
