Selecting the correct size Line set (refrigerant piping) for your HVAC system is a critical step in ensuring that your system operates efficiently. There are several key factors to consider when choosing the correct size:

• System capacity and type: First, the capacity of the air conditioning or heat pump system needs to be known (usually expressed in tons or BTU/h). This will have a direct impact on the diameter size of the line set required. Higher-capacity systems will require larger-diameter line sets to ensure adequate refrigerant flow.

• Line set length: The length of the line set affects refrigerant flow and pressure loss. Generally, the longer the line, the larger the required pipe diameter may need to be to minimize pressure loss.

• Professional Evaluation: Consider asking our customer service at manufacturer@dellahome.com for a recommendation on the right line set for your needs; this ensures that all factors are taken into account to select the most appropriate pipe size.
