If I buy a 16 ft. additional line set to add to my 25 ft., will I need to add Freon?
Thank you for your question. DIY line sets do not require any additional refrigerant because they are pre- charged. However, it is important to note that this line set is compatible with MRCOOL DIY systems. To use this line set as an extension, a line set extension kit will be required to effectively connect the two line sets. For assistance in determining what you will require for installation, please give us a call.
