Have a question about the central unit MRCT 200CWN1 D(C) According to the manual, the return duct and the supply duct should be a specific size. What would be the consequences of installing ducts smaller than the recommended dimensions? I would appreciate any information you can offer on this topic. Thank you.

Installing ducts smaller than the recommended dimensions can reduce airflow, which may lead to the following consequences:

1. Decreased cooling or heating efficiency.
2. Increased system pressure, potentially overloading components.
3. Higher energy consumption and operating costs.
4. Reduced equipment lifespan due to strain on the system.
5. Poor temperature distribution and comfort issues.

Proper duct sizing is essential for optimal performance and efficiency.
