What is required for AC installation – Complete Guide?

Mar 28, 2023

AC installation service is an essential part of modern living. Iinstallation of an air conditioning system requires careful planning and execution to ensure that it functions properly and efficiently. If you are considering an AC installation. This complete guide will provide you with all the information you need to ensure a successful installation.

A good AC installation service is essential not only for the longevity of your air conditioner, but also for it to perform well. A properly install air conditioner will provide adequate cooling while also increasing durability. It also aids in obtaining service and maintenance under warranty.

While a professional installs an air conditioner, it is important for you as a consumer to understand some key aspects of installing a split air conditioner.

Installation Site

Locate the indoor and outdoor units precisely. You don’t want to install the air conditioner in a location where the cooling is ineffective or so cold that you feel like you’re in the Arctic.

Wall Strength

Check that the wall that will house the air conditioner’s indoor unit is sturdy enough. It must be able to withstand the unit’s vibration.

Dividing line

It is recommended that the indoor unit of the split AC have at least 10 – 15 cm of open space around its top and sides. This is required for proper air flow. Inhibiting air flow could make it more difficult to expel heat. This will fuel your operating costs of air conditioners. It also has the potential to harm the compressor.

Indoor unit height

In a 10 ft high room, a height of 7-8 ft above the ground is recommend for optimal cooling. This ensures that cool air circulates evenly throughout the space. It also ensures that the air conditioner is not overworked cooling the hot roof, resulting in a higher electric bill for you.

Outdoor unit location

Open space is ideal for the outdoor unit of a split air conditioner, perhaps on a terrace, in the balconies, behind a side wall, or on Pari Pari slabs, in a location that is safe and secure for installation and servicing there is nothing to obstruct the flow or air in open space. This will give your compressor and condenser plenty of room to work. Make certain that the outdoor unit is not directly exposed to sunlight.

If a terrace is not available, an external space with a strong wall capable of supporting the weight of the outdoor unit without restricting air flow is also suitable.

Furthermore, it is essential to set the outdoor unit down on a flat surface. The outdoor unit houses all of your air conditioner’s critical components, including the compressor and condenser. Outdoor units are vibrating. If the surface is not flat, continuous vibration may occur, particularly during the summer months when the air conditioner is used almost constantly this can cause compressor and condenser damage. A faulty compressor and condenser is useless. This will raise your service costs and, in the worst-case scenario, necessitate the replacement of the unit itself.

Separation of indoor and outdoor units

Your air conditioner must operate as effectively and efficiently as possible, so the distance between the two units is vital. The performance improves with decreasing distance.


  • Maintains proper cooling
  • Ensures the unit’s efficient performance
  • Ensures that the unit uses less energy, lowering your monthly bill.
  • Reduces service and maintenance expenses
  • Extends the life of your air conditioner

Choosing the Right AC installation service

The first step in the installation process is to choose the right air conditioning system for your home or office. You should consider the size of the space you want to cool, your budget, and the energy efficiency of the system. There are several types of air conditioning systems available, including split systems, window units, central air conditioning systems, and portable air conditioners. Consult with an AC installation professional to determine which system is best suited for your needs.

Proper Sizing

Once you have chosen the right system for your space, the next step is to properly size the system. The size of the system is determined by the cooling load of the space it will be installed in. Factors such as the size of the room, the number of occupants, the amount of sunlight that enters the space, and the insulation of the room all affect the cooling load. An AC installation service professional can perform a cooling load calculation to determine the proper size of the system.


The location of the AC unit is crucial for its proper functioning. The outdoor unit should be placed on a flat surface, away from direct sunlight and sources of heat, such as exhaust vents or hot water tanks. The indoor unit should be placed in a location that is free from obstructions and provides proper airflow. If the unit is not installed in the right location, it can lead to reduced efficiency and increased energy consumption.


If you are installing a central air conditioning system, ductwork will be required to distribute the cool air throughout your home or office. The ductwork should be properly sized to ensure that there is adequate airflow to all rooms. The ducts should also be sealed properly to prevent air leaks, which can reduce efficiency and increase energy consumption.

Electrical Wiring

An AC installation service requires electrical power to function. The wiring should be done by a licensed electrician to ensure that it is done properly and meets all safety codes. The wiring should also be properly sized to ensure that it can handle the electrical load of the system.

Condensate Drain

An air conditioning system produces condensate, which needs to be drained properly to prevent water damage to your home or office. The condensate drain should be properly installed and sized to ensure that it can handle the amount of condensate produced by the system.

Start-Up and Testing

Once the installation is complete, the AC unit should be started up and tested to ensure that it is functioning properly. The AC installation professional will check for proper airflow, refrigerant flow, and electrical connections. They will also check for any leaks or other issues that could affect the performance of the system.

Wrap Up:

 An AC installation service is a significant investment, and it is important to ensure that it is installed correctly to provide you with years of efficient cooling. By following these steps, you can ensure that your AC installation is successful and that your system is functioning properly. Consult with an AC installation professional for any questions or concerns you may have.
