How to choose the correct Air Conditioner

A: Portable air conditioners are great for use in smaller, enclosed areas like bedrooms or offices where local cooling is required. By choosing spot cooling, consumers can save on energy and operation costs. These units are very efficient and reliable, and they have the benefit of mobility. Many units are set on casters allow the units to be easily rolled from room to room as needed. Portable units remove hot air from the room and must be vented out of a window so the hot air is released. The window exhaust kit included with Haier models makes this process quick and simple. Check out this video to learn how to install a portable AC unit such as a Commercial Cool unit.
Window air conditioners. The biggest difference between portable and window units is that window air conditioners are installed and secured in window frames and are meant to be kept there for the entire season. They are stationary units but can be removed from windows at any time to be stored after the season. Window air conditioners draw in air from outside and cool it before releasing it into a hot room. This process cools down areas quickly and quietly. Some air conditioning units also clean and purify the air in your home by reducing allergens and dust.
With models that run from 5,000 BTUs through 24,000 BTUs, and most are ENERGY STAR® qualified, so it's easy to find a Haier air conditioning unit that’s perfect for each room in the home. The ESA406K and ESA412K were both rated as best buys by a leading consumer magazine.
ENERGY STAR qualified room air conditioners use about 10% less energy than conventional models, which could mean a savings of more than $60 over the lifetime of the unit.
Q: What size air conditioner is right for my room?
It’s important to choose an air conditioner with adequate BTUs for the size of the space. Two few BTUs can result in insufficient cooling, and even having too many BTUs can negatively affect cooling performance. The size of the space being cooled is the most important aspect to consider, but other factors such as the number of people normally occupying a room, and sources of additional heat like windows should also be taken into account.

Tips- If more than two people normally occupy a room, add 600 BTU’s for each additional person.
        If a room is very sunny, increase BTU’s by 10%, if it is shady, decrease BTU’s by 10%.
        If the unit is for a kitchen, increase by 4,000 BTU’s.
