Copper Pipe for AC Installation

Copper pipes are commonly used in air conditioning systems for several reasons. They are durable, easy to install, and have excellent heat transfer properties. Best copper pipe for AC is also resistant to corrosion, which makes them ideal for long-term use in an AC system.


There are two types of copper pipe used in ac systems: soft copper and hard copper. Soft copper wire is flexible and is used for refrigerant lines in split-system air conditioners, where it needs to bend around corners and obstacles. Hard copper, on the other hand, is rigid and is used for the condensate drain in an AC system.


The size of the copper pipe for AC installation depends on the size and type of the AC system. For example, a typical residential split-system air conditioner might use a 3/8-inch pipe for the liquid line and a 3/4-inch pipe for the suction line.


Copper pipe for AC installation should be installed by a professional to ensure they are properly fitted and sealed to prevent leaks. The copper pipe for aircon should also be insulated to prevent heat transfer and condensation.
