Line Sets and Install Tools
Pre-flared insulated copper line sets by length and pipe size, plus flare fittings and the tools for a professional-style install.
The line set must match the system's two connection sizes, usually 1/4 inch liquid with 3/8 or 1/2 inch suction for 9,000 to 18,000 BTU systems, and bigger on larger ones. Check your system's manual for the sizes and for its minimum and maximum line length.
Most systems ship pre-charged for a set length (often 16 or 25 ft); longer runs need extra refrigerant added by a technician. Copper line sets need a vacuum to be pulled before the system is opened; that's why DIY quick-connect kits use sealed, pre-charged lines instead.
Start with your situation
A typical 9,000-12,000 BTU install
Up to 25 ft line sets, mostly 1/4 x 3/8 in, cover most small systems.
A long run from the condenser
33-50 ft sets for longer runs; extra refrigerant is needed beyond the pre-charge length.
You're doing the flare connections
Flare seals, tool kits and vacuum pumps for open-flare installs.
Before you buy
- Match the pipe sizes. Both the liquid and suction sizes must match the condenser's service valves.
