As the days get longer, the temperature starts rising, imperceptibly at first. Within a matter of weeks it is just plain warm and starting to get uncomfortably warm. This is really the best time to shop around for an air conditioner. Look around, do some research, but make sure you get one installed before the scorching heat makes you feel you may melt. Before you know it the dog days of summer are upon you.
But how exactly does an AC work? An air conditioner is made up of two separate parts. There is what is known as a condenser and a coil. Inside the condenser a cooling gas is compressed and cooled. Then this is passed through the coil. Finally a blower then is utilized to pass the cool air into the room.
There are different types of air conditioners; there are the individual units or the central air conditioners. Usually the latter is used in offices, malls and larger homes. The individual units are available in two varieties. The wall mounted type and the window mounted variety. Wall units are installed in holes cut into the side of exterior walls. As they do not take up window space they have become more popular. But these wall units need a lot more effort to install.
In case you opt for the window type do make sure you measure the dimensions of the opening very carefully before you order your new AC. Even a couple of inches off will result in major difficulties fitting it in. And of course the size of the room that needs to be cooled should be taken into account. Accordingly the size of the AC should be in keeping with the size of the room. AC size is measured in BTU (British Thermal Units) which is basically the amount of energy required to raise the temperature of a pound of water by a degree. For convenience this has now been converted to tons. One ton is equal to 12,000 BTU. Therefore the greater the BTU the greater it’s cooling ability.
When you visit the stores to check out the air conditioners available you will need to compare some features. Check out the noise level. These days’ air conditioners are a lot quieter than they used to be. Make sure you don’t get saddled with a rattling wheezing type which will ruin your sleep. The thermostat should be efficient enough to maintain a preset temperature level. There should be well designed louvers to direct the cool air up and down, right and left.
Some air conditioners can switch from fresh air to recirculated air. This enables you to switch to outside air when it is not too warm, and then switches to recirculated air when you need to cool down the room. Some air conditioners have filters in them to purify the air and remove allergens such as the Bosch anti-bacterial units. Look for an air conditioner that has built-in timers. This enables you to turn the unit on or off on a predetermined schedule. This way you can set the AC to turn on itself on before you return home from work and enjoy the comfort of a deliciously cool environment.
