Frequently Asked Questions

What size line set do I need for my mini split?

Check your mini split's installation manual. Most 9,000-12,000 BTU units use 1/4" x 3/8". Larger 18,000-24,000 BTU units typically use 1/4" x 1/2" or 3/8" x 5/8".

Do I need to add refrigerant with a longer line set?

Most mini splits come pre-charged for up to 25 feet of line set. If your run exceeds the factory charge length, additional refrigerant must be added per the manufacturer's specification (usually 0.6 oz per extra foot).

Can I cut the line set shorter?

Yes, but you must re-flare the cut end using a proper flaring tool. Never use compression fittings on refrigerant lines.

Are the connections flared or do I need to braze?

Mini split line sets come pre-flared for flare nut connections — no brazing required. This makes DIY installation feasible for capable homeowners.
