Are the linesets pre-flared when I buy a mini split?Updated an hour ago

Yes. The linesets are factory pre-flared and ready for connection. All Pioneer equipment purchases that were selected to include an installation kit will be accompanied by the pre-flared linesets. The linesets will also be included with systems that are boxed with a set of lines.

The linesets will only need to be re-flared if they are being shortened or there is damage discovered during installation.

Pioneer only uses copper lines conforming to ASTM B280 standard with 45° flares.
