Can I use a lineset of a different size than what is recommended?

It is highly recommended to use a lineset of the size recommended by the manufacturer. The recommended size is determined based on several factors like the air conditioning unit's capacity, refrigerant type, and overall performance. Using a lineset of a different size can have adverse effects on the air conditioning system's efficiency, performance, and longevity. A lineset that is too small may cause decreased cooling or heating capacity, increased energy consumption, and potential damage to the compressor. On the other hand, if the lineset is too large, it can lead to refrigerant flooding, inefficient operation, and potential system failure. To ensure optimal performance and avoid any potential issues, it is crucial to adhere to the recommended lineset size for your specific air conditioning system.
