Installing a Central Air Conditioning Unit

As a central air conditioning unit can deliver cooled air to several rooms at the same time, it is also termed as a split system. The split system also has a split component: a component housing the condenser and compressor outdoors, and a component accommodating the evaporator and air handler indoors.

People want to purchase the model because a central air conditioning unit provides many benefits. Aside from the safe, cool air, it cleanses the air as its filter removes airborne particles like lint, dust, and other microscopic pollutants. It also works quietly, especially since the noisy condenser, fan, and compressor are located outside the house.

If you opt to install a central air conditioning unit in your home or office, here are some guidelines for you:

Step 1: Plan. Consult a licensed air conditioning contractor before purchasing a unit. He will perform a load calculation which will determine what unit best suits your building. The contractor will assess factors such as the amount of attic and wall insulation, the orientation of your home to the sun, and types and placement of windows and doors. This will reveal what size of unit you need. Size matters because an undersized unit cannot cool rooms down completely on the hottest days, while an oversized unit consumes more electricity and does not lower humidity effectively, leaving a room clammy and damp.

Step 2: Install. Now that you have purchased the right unit, you are ready to install. Carefully follow all instructions and safety guidelines, like turning off the main power prior to the installation. Another thing: make sure to hire an expert technician for the installation. Installing a central air conditioning unit is not a do-it-yourself process. First, install the air handler unit (usually in the basement or attic). Second, place the compressor on an empty, stable and level surface outside. Then, cut holes through walls for the tubes. Connect compressor and air handler to the main power unit of the house. Lastly, switch on and check if the unit is working. By the way, it takes hours or even days to complete the installation, so it is really better to seek professional help instead of taking a risk.

Further, since you are still to buy a central unit, the last thing to be discussed here is the budget. The costs vary but experts give their estimates as follows: if the unit is to be added to an existing heating system in a 2,000 sq. m. building that needs little or no change to the existing ducts, you may incur an average cost of $3,500-$4,000; if for an older, smaller building of 800-1,000 sq. m. with no existing ductwork- you may incur $2,000-$10,000; and if ducts are to be added, expect to spend $7,000-$8,000.

Actually, central air units are not usually directly sold to customers because installation needs the complex efforts of a licensed contractor. So if you are to buy a central unit, look for the one in a package deal which includes the air conditioner, ductwork, permits, and labour. Again, we strongly reinforce that to ensure energy efficiency, cost cutting and environmentally friendly central air conditioning, proper consultation with proper people should be done before installation.
