The AIM Act phasedown is not a future problem. R-410A production caps are already in effect — new equipment ships with A2L refrigerants now. Every tech without this knowledge is walking into equipment they can't safely service.

Built for the Tech Who Can't Wait to Learn on the Job
The Residential Tech
You've serviced R-410A systems for years. R-454B is showing up on new installs and you want to know exactly what changes before you touch it.
The Service Manager
Your team is already getting called out on A2L equipment. You need everyone current fast, without sending them to a 2-day course.
The HVAC Student
You're training for a career that's already mid-transition. Understanding both refrigerants before you hit the field puts you ahead of everyone who learned on R-410A only.
From Techs Already Working with A2L
“I had a new mini-split with R-32 and honestly didn't feel confident on the charging side. This guide walked me through the A2L differences in about 20 minutes. Saved me a callback.”
Marcus D.
Service Tech, Phoenix AZ
“I recommend this to every student before they touch new equipment. The side-by-side comparison table alone is worth the price.”
Tony R.
HVAC Instructor, Dallas TX
“The retrofit vs. replace flowchart is the part I keep coming back to. Customers ask me this question every week now.”
