Can a Split System Air Conditioner be Installed on an Internal Wall?

Installing a split system air conditioner on an internal wall can present some unique challenges. While it is technically possible, the success of the installation largely depends on the specific layout of your home and the availability of routes for the necessary components. Here, we will explore the feasibility and provide some guidance on how to proceed.

Challenges and Considerations

One of the primary challenges in installing a split system air conditioner on an internal wall is the routing of the copper lines and condensate. These components are essential for the proper operation of the air conditioner and require careful planning to ensure they function correctly.

Routing the Lines

To effectively route the lines, several routes can be considered:

Attic or Basement: In some cases, it may be possible to route the lines through the attic or basement and then run them horizontally or vertically to connect to the internal wall unit. This approach can minimize the length of the copper lines needed, but it depends on the availability and accessibility of these spaces. Exterior Walls: If an exterior wall is accessible, you may be able to run the lines more directly to the external condenser unit. This can be more straightforward but might require modifications to the exterior of the building. Plumbing Solutions: In cases where direct routing is not possible, you may need to consider the use of a pump to handle the condensate. This involves installing a pump that can transfer the condensate horizontally or vertically to a suitable drainage point.

Construction and Accessibility

The construction methods used in your home can significantly impact the feasibility of the installation. Some building designs and materials may make it nearly impossible to connect the indoor and outdoor units of a split system air conditioner effectively. For example, thick walls, lack of suitable channels, or internal obstacles can create significant challenges.

Key Considerations:

Distance from Outside Wall: The further the split system air conditioner is from a suitable outside wall, the more copper pipe is needed. This can greatly increase the complexity and cost of the installation. Building Obstructions: Certain construction methods and building designs may create obstacles that prevent direct and efficient routing of the necessary components. Hidden Conduits: Small hidden conduits within walls or ceilings might pass unnoticed, but they can be crucial if they provide the necessary pathways for the lines.

Technical Requirements and Installation Steps

Before you proceed with any installation, it is crucial to have a basic understanding of the technical requirements and the steps involved:

Professional Assistance: Given the complexity of these installations, it is highly recommended to seek assistance from a professional HVAC technician. They have the experience and tools necessary to ensure a safe and effective installation. Site Assessment: A thorough site assessment should be conducted to evaluate the specific challenges and potential solutions for your home. Planning and Design: Detailed planning and design are essential to create a route that minimizes the length of the copper lines and accommodates the condensate. Installation: The actual installation process will involve running the copper lines and installing the condensate pump, if necessary. This step requires precise measurements and careful attention to detail. Testing and Maintenance: Once the installation is complete, thorough testing is essential to ensure that the air conditioner operates correctly. Regular maintenance can also help prolong the lifespan of your system.

Conclusion and Final Thoughts

While installing a split system air conditioner on an internal wall is possible, it is crucial to carefully consider the challenges and potential solutions. Factors such as the availability of routes, construction methods, and the distance from suitable outside walls can significantly impact the feasibility of the installation. A professional approach with detailed planning and execution will ensure a successful installation that meets your cooling needs.
