MRCOOL Easy Pro vs DIY: Line Set, SEER2, and Price
MRCOOL sells two true-DIY single-zone lines and the difference is concrete: the DIY line includes a 25 ft pre-charged line set and runs higher SEER2; the Easy Pro includes a 16 ft set, slightly lower efficiency, and costs roughly $700-$1,200 less per system at the same size (compare the rows below - both are in our verified dataset). Neither is 'the budget version with worse parts'; it is a line-length and efficiency trade.

Buying notes
- Measure your run first: a 16 ft set that reaches is the Easy Pro's whole case; a run past 16 ft decides for the DIY line by itself.
- At 12,000 BTU the DIY line is also the 115V model in our data - check your panel before choosing.
