Can I use my current copper line set instead of buying a new one. Will the warranty still be good?

It's recommended to replace your line set when installing a new condenser, but you can reuse it without any negative effect on the warranty. If you do reuse it, please make sure that the lines get flushed before being attached to the new units. You will also want to ensure that your old lines are the correct size for the new units.

If you have any further questions, please call us and we will be happy to assist you.
