Advice on choosing the right air con unit.
There are a couple of things to consider when buying a new air conditioning unit for your home. Chief amongst them is budget. This will determine what type of air con unit you can afford, which after all, is going to narrow down the selection.
Second, what sort of space are you working with? Do you only need air con in one room? A whole house? There are different air conditioning units available for different purposes, from portable window units to central systems. Make sure you know what you need before buying.
Third, do you want a permanent fixture or a portable one? Again, there are a variety of options available at different price points, some which can be moved around easily, some which are stuck in place. Make sure you’re happy with an internal/external unit before buying one that requires this type of installation.
To help you decide, here are some of the most common units available –
WINDOWSILL UNIT – As the name suggests, these are smaller, and sit on a window, wedged underneath the pane. They are usually only used seasonally, and packed away in winter when no longer in use. Due to the size of these units, they are only really useful for smaller rooms, and are certainly incapable of serving as an air con unit for a whole house. On the flipside, they are far more inexpensive than a central system.
SPLIT SYSTEM UNIT – These live both internally and externally. One part of the system is outside and compresses the air, while the other part is inside and cools it. These are, like the windowsill units, usually only used to cool one room, but obviously with more power. They are available in a range of sizes.
CENTRAL/PACKAGED UNIT – So called because they can cool an entire area or house effectively. They can be bought in a variety of configurations, with one compressor servicing several cooling units spread throughout the home, or one compressor and one cooler which vents through the space. These are far more difficult to install, so it’s likely you’ll need professional help.
