25' R-454B No-Vac Lineset — Model Details

What this specific model is sized for, how it installs, how it performs, and what it costs to run.

Install Difficulty — Professional Install

This is a professionally-installed condenser that requires a licensed HVAC technician with EPA 608 certification. The tech will pull a vacuum on the line set to 500 microns, pressure-test with nitrogen, release the factory charge, and commission per MrCool's startup procedure. Budget 1 full day for install on a single-zone system. Ships with R-454B refrigerant. R-454B is the EPA 2025-compliant low-GWP replacement for R-410A, required for new-manufacture equipment — lower global-warming footprint without an efficiency penalty.

What's in the Box & Compatibility

Ships as a Accessories Line Set. Designed to pair with VersaPro 2nd Gen - Central Ducted Hyper Heat 2nd Gen. If you're buying a condenser-only SKU you'll need to match it with a compatible air handler or head unit of equal or smaller total BTU.
