Copper tubing is a popular material of choice when installing a mini split system. Copper is a good conductor of heat, and its ductile nature makes it easy to work with and install. In this post, we’ll provide an overview of the types of copper tubing used in mini split AC systems, their advantages and disadvantages, and installation tips.
The two main types of copper tubing used in mini split systems are hard drawn copper and soft drawn copper. Hard drawn copper is a type of copper tubing that is drawn through a die to produce hard, rigid tubing. It’s more expensive but has greater strength and is more resistant to corrosion. Soft drawn copper is a type of copper tubing that is drawn through a die to produce a softer and more flexible tubing. It’s less expensive than hard drawn copper but is less resistant to corrosion.
Both types of copper tubing have their advantages and disadvantages. Hard drawn copper is more rigid and is better at resisting corrosion, so it’s the better choice for long-term installations. However, it is more expensive and may be difficult to work with. Soft drawn copper is more flexible and cheaper, but it is more prone to corrosion and may need to be replaced more often.
When installing copper tubing for a mini split system, it’s important to use the right type of tubing for the job. Hard drawn copper should be used for long-term installations, while soft drawn copper is better suited for short-term and/or temporary installations. It’s also important to choose the right size of tubing for the job. Too large a tubing size can result in reduced airflow, while too small a tubing size can result in restricted airflow.
When installing copper tubing for a mini split system, it’s important to use the proper tools and techniques. If you’re using hard drawn copper tubing, it’s important to use a tubing bender to form the tubing to the desired shape. If you’re using soft drawn copper tubing, it’s important to use a tubing cutter to cut the tubing to the desired length. It’s also important to use the proper fittings and connectors to ensure a secure connection between the copper tubing and the mini split system.
