How To Install A Split Ac?

If you have decided to install a new split A/c in the house, then you should know that proper care should be taken to install the machine. The performance of the machine depends a lot on its right installation. It has often been found that users complain of insufficient cooling by their A/cs. After examining, the fault was found in improper installation which also gives rise to maintenance problems. Always get in touch with a knowledgeable technician/contractor to get your spilt AC installed. It requires lots of practice to become an expert split AC installation and erection technician.

A contractor takes into account an array of factors before installing a split AC. Here are some of them:

Deciding the location

The foremost consideration towards installing a split A/c is to decide upon the locations where the indoor and outdoor unit of the system would be placed. In this there are umpteen factors to take into consideration for selecting the best possible location. They are:

• The indoor unit should be located in place where the air will be distributed un-obstructed throughout the room. Ideally, the unit should be installed above the bed, if it is a bedroom. This way you can get maximum flow of air when lying on your couch. If you find the air much too cool, almost chilled then you can alter the direction of the louvres to let it flow in another direction. The indoor unit can also be installed on other walls. But the wall should be strong enough to hold it.

• The height at which you will mount the air conditioner should be about 8 to 10 feet from the floor. It should also have at least 15 cm of open space surrounding its top and sides for proper air flow. Remember, the unit should cool the roof and not the hot roof.

• The indoor unit should be installed within a reachable distance of a user. He should be able to clean or change the filters on regular intervals.

• If the unit mounted over a window it should be at symmetry with it. The air conditioner should add to the aesthetics of your room and not destroy it.

Now here are some considerations for the outdoor unit:

• The outdoor unit should be placed on the terrace where there is free flow of air. It should not be kept in congested, dusty, or hot areas. If terrace is not available then you can keep it on the awnings. Or you can simply mount it on the external all.

• It requires 12" of space surrounding its perimeter to ensure proper functioning.

• It should be positioned so that it can be accessed by the user or technician for repairs and maintenance whenever required.

• Also take care that the unit is not surrounded by too much shrubs and bushes. These will smother the unit so that the air from the outdoor fan will not be able to get into the surrounding. Blockages will affect the performance of the AC and can also lead to the burning of hermetically sealed compressor coil.

• The surface, on which the outdoor unit will stand, should be stable enough to avoid vibration during operation. Vibration will cause disturbing noises. And it will also can damage copper tubing inside and cause leakage of the refrigerant.

• It is always wise to keep the outdoor unit at a greater height than the indoor unit. This will allow the compressor to send the refrigerant to the evaporator without any effort. Otherwise it may have to pump the refrigerant against the gravity. This will cause a stress upon the compressor.

• The refrigerant flows between the indoor and outdoor unit through tubing. Some of the effect of the Freon is lost on the way. Therefore the distance between the indoor and outdoor unit should be minimum.

Now comes installation!


• As for the indoor unit is concerned, hold the mounting plate in such way that both sides are horizontally at the same level. Mark two spots just below the plate and drill holes there. Secure the mounting plate with brackets by using screws.

• Now make sure there is an electric socket close by where you can plug on the interior unit.

• A hole has to be drilled on the wall closely from where the piping from the indoor unit would run towards the outdoor unit. When running the pipe, ensure that there is minimum bending.

• Bind the copper pipes, the power cables and the drain pipe together with electrical tape. Ensure each of these is connected to appropriate places in the indoor unit. Make sure that the connections are tight. The water drainage pipe would generally go at the unit’s base.

• Run the bound pipes and cables through pipe passing through the hole in the wall. Make sure that the drainage pipe allows takes the condensate in the right place.

• Now place the outdoor unit at the place that is selected. Connect the bound pipes to the corresponding pipes on the outdoor unit. The cable of the outdoor unit should also be connected to a power panel.
