Proper installation of an air conditioner is crucial to ensure efficient cooling performance and energy savings in your home. In this article, Mytour Supermarket will summarize important insights into installing a newly purchased air conditioner. Let's explore and apply these insights to turn your home into a cool and comfortable oasis during the hot summer days.
Compilation of Tips for Properly Installing a Newly Purchased Air Conditioner
1. Choosing the Right Installation Location
Choosing the right installation location greatly impacts the operational efficiency and energy savings of the air conditioner. Here are some considerations when selecting the appropriate installation location for your air conditioner:
- Avoid direct sunlight: Sunlight can increase room temperature significantly. Placing the air conditioner near windows or areas exposed to direct sunlight will cause the air conditioner to work harder to cool the space. This will consume more energy and increase electricity bills. Avoid placing the air conditioner in such locations and use curtains or blinds to block sunlight.
- Ensure air circulation: For efficient operation, air circulation in the room needs to be unrestricted. Avoid placing the air conditioner in locations obstructed by furniture or objects. If air cannot circulate properly, the air conditioner will not effectively cool the space, and you may feel uncomfortable.
- Accessibility for maintenance: Ensure that you can easily access the air conditioner for cleaning and maintenance. Regular cleaning is necessary to maintain the cooling and refrigeration performance. If it is placed in a hard-to-reach location, maintenance becomes more complicated and may be overlooked.
- Convenient control: Ensure that the air conditioner controls are easily accessible and not obstructed. This helps you adjust the temperature and cooling modes effortlessly without much effort.

2. Identify the position of the drainage pipe
Determining the position of the drainage pipe is a crucial step in the air conditioner installation process. This is where condensation from the air conditioner will be drained, and identifying the correct location can prevent the following issues:
- Prevent water leakage: If the drainage pipe is not properly identified, water may flow out from the air conditioner and cause water leakage on the walls or floor. This can damage the structure of the house and create conditions for mold growth.
- Easy maintenance: Identifying the position of the drainage pipe accurately allows you to easily conduct maintenance and clean the air conditioner. This also helps prevent the accumulation of dust or debris due to water drainage.

3. Proper installation of the indoor unit
When installing the indoor unit of the air conditioner, the installation location is a crucial factor to ensure optimal performance. Here are the specific instructions:
Step 1: Choose a suitable location
Avoid installing the indoor unit in places where direct sunlight shines or where there is a significant temperature difference, such as near doors or windows. This prevents the cold air flow from directly encountering hot air, helping to avoid sweating and water leakage from the air conditioner.
Step 2: Ensure proper airflow direction
Install the air conditioner so that the cold air flow blows vertically along the room, avoiding cross or corner airflow. This ensures even temperature distribution in the space.
Limit installing the indoor unit in locations obstructed by objects, as this can affect efficiency and increase power consumption.
Follow the manufacturer's installation instructions or seek professional installation to ensure the unit operates efficiently and safely.
Step 3: Wrap insulation properly
When installing copper pipes and refrigerant lines, wrap insulation carefully to prevent heat loss and refrigerant leakage.
Step 4: Adjust to the appropriate height
Ensure the indoor unit is installed at a convenient height for easy maintenance and cleaning.
Proper installation will help the air conditioner operate more efficiently, save energy, and extend its lifespan. For accuracy, you can seek assistance from experienced professionals or technicians to perform this task.

4. Routing Copper Lines from Indoor to Outdoor Unit
Step 1: Bend the copper tubing to reach the outdoor unit location. This ensures the tubing is long enough to connect the two main components of the air conditioning system.
Step 2: Use specialized pliers to flare the end of the copper tubing, then connect it to the copper line on the outside.
Note: Flaring the end of the copper tubing is crucial. The tubing must be flared using specialized tools, adhere to correct techniques, and fit tightly with the connecting end to ensure no leakage of refrigerant and coolant during usage.
Step 3: Connect the tubing end with the copper line on the outside. The tubing end will have a fitting, and you need to connect it with the copper line. Ensure a tight connection to prevent refrigerant or coolant leakage. After connecting, use a wrench or suitable tool to tighten the two connection points together.
5. Proper Installation of the Outdoor Unit
Installing the outdoor unit of an air conditioner requires attention and adherence to the following principles:
Installation Location: The outdoor unit is typically placed outside the room. Avoid placing it directly against the wall as this may result in louder noise. Instead, consider positioning the outdoor unit in a corner or similar location to minimize noise.

Rubber Base Stand: When installing the outdoor unit, use a rubber base stand to elevate it. This helps reduce the unit's vibration, minimize noise, and protect the outdoor unit from vibrating on the surface.

Placement of Indoor and Outdoor Units: If possible, install the indoor unit higher than the outdoor unit. This helps the refrigerant oil return to the outdoor unit more easily, reducing the risk of oil shortage for the outdoor unit. It can also save maintenance effort and extend the lifespan of the system.
Installing the Outdoor Unit Higher than the Indoor Unit (3 meters or higher): When installing the outdoor unit at a height higher than the indoor unit (3 meters or higher), consider installing an oil trap system. This system aims to limit the occurrence of oil shortage for the outdoor unit, as it cannot draw refrigerant oil back from the indoor unit.
Below are step-by-step instructions for properly installing the outdoor unit of the air conditioner:
Step 1: Measure the two feet of the outdoor unit and determine the distance between them to secure the outdoor unit. This ensures that the outdoor unit is balanced and stable.
Step 2: Use a spirit level to align the installation position of the outdoor unit so that it is balanced. This ensures that the outdoor unit is not tilted or skewed.
Step 3: Attach the L-shaped bracket to the wall at the designated location. Then, use a drill to secure the L-shaped bracket with screws.
Step 4: Place the outdoor unit on the mounted L-shaped bracket on the wall and begin the connections. Connect the copper wires you prepared in the previous steps to the outdoor unit of the air conditioner. Use a wrench to tighten the connections.
Step 5: Wire the outdoor unit by connecting the electrical wires according to the manufacturer's instructions. Then, wrap insulation around the gas and refrigerant valves on the outdoor unit to ensure safety and prevent leaks.
It's crucial to note that installing the outdoor unit needs to be done carefully and following the manufacturer's instructions to ensure the air conditioner's optimal performance. If you lack confidence or necessary skills, it's advisable to seek out an experienced expert or technician to handle this task.
6. Consulting an Expert for Air Conditioner Installation
If the installation is not carried out correctly, it can lead to issues such as improper functioning, gas leakage, water leakage, or reduced lifespan of the unit. This can result in wasting time, money, and adversely affecting the users' health.
Here are some reasons why you should contact an expert for air conditioner installation:
