🚀 How Our Line Set Options Work:
-
Standard System:
Every system from MRCOOL comes factory-bundled with a 25′ pre-charged line set and 25′ of control wire. -
Choosing an Alternate Length:
If you select a different line set length (such as 16′, 35′, 41′, 50′, or 75′):-
Your order will be custom-bundled individually at our warehouse.
-
This process typically adds 1–2 extra business days for preparation and shipping.
-
You will receive the exact pre-charged line set footage you requested — either as a single line set or a combination of two line sets (if needed) to achieve the proper length.
-
📦 Important Details to Know:
-
Single vs Combined Lengths:
-
16′: Factory 25′ is swapped for a 16′ pre-charged line set.
-
35′: A single 35′ pre-charged line set is provided.
-
41′: Combines your standard 25′ line set with an additional 16′ line set + supplied coupler + extended control wire.
-
50′: A continuous 50′ pre-charged line set is provided with longer control wire.
-
75′: Combines a 25′ + 50′ pre-charged line set with couplers and 75′ of extended control wire.
-
-
Control Wire Upgrade:
Any time your line set length exceeds 25′, you will receive a new longer control wire matched to the total length.We never recommend splicing control wires. These systems are essentially computers — shielded, continuous control cable ensures no interference, no corrosion, and no installation headaches down the road.
