The Industry Shift
A2Ls ARE ALREADY HERE
R404A and R448A/449A are being phased down globally. A2L refrigerants offer up to 96% GWP reduction versus R404A — and technicians are already encountering them on every new install.
~96%
GWP Reduction
Versus R404A, A2L refrigerants represent a massive reduction in global warming potential. The Kigali Amendment and F-Gas regulations are accelerating this phase-down worldwide.
Now
Technicians Installing Today
Engineers and technicians are showing up to A2L installs with only basic wholesaler walk-throughs. This course gives you the depth to design, install, and service safely and with confidence.

What Engineers Say About Our CO2 Course
From our Advanced CO2 Design Course — the same instructors, the same commitment to real-world depth.
Exclusive Course Bonus
World's First Full Piping Layout Software
Every course participant receives a free 6-month trial of MicroPipe — the world’s first fully comprehensive piping layout tool for refrigeration designers. Built by Nabil Cook, Technical Director of Omega Solutions, it saves designers thousands of hours per year versus single-line software or manual charts.
Double Riser Functionality
Nabil Cook has successfully added double riser functionality for dry suction lines — a first in the industry for software of this kind.
Min & Max Oil Return
In addition to minimum oil return at lowest loads, maximum oil return is also calculated for the larger branch at high to peak loads — complete system confidence.
Manual Fix Size Control
Lock in pipe sizes before or after calculations. Mix fixed and auto-sized pipes in the same network. Fix or unfix individual rows — or all at once — instantly.
Solver + Your Expertise
Let the solver validate while you set your own velocity constraints. Hold onto what you trust and keep iterating — no more rerunning from scratch.
Full Network Builder
Map complete pipe networks — evaporators, risers, ringmains — with automatic path calculations, pressure drops, and pipe-system volume outputs.
Complete Output Data
Size, gauge, oil return %, velocity, penalty kPa, pipe kPa, collated kPa, valve kPa, flowpath totals — every number a designer needs, instantly.
6-Month Trial — Included With Your Enrollment
All course participants receive a free 6-month trial of MicroPipe as part of their enrollment. No extra cost — it’s built into the $997 course fee.
