HazCom & SDS Software for HVAC Contractors (2026)

Updated September 2026

HVAC and refrigeration crews handle a truckload of chemicals an OSHA inspector cares about — refrigerants, brazing flux, coil cleaners, solvents and oils — and the November 20, 2026 OSHA HazCom deadline means the labels, the written program and the training all have to be current and in GHS format. On top of that, the move to A2L refrigerants adds a flammability hazard that didn't used to be there. Here's what SDS and HazCom software does for a contractor, what to look for, and how it works across branches.

The A2L change, and why it lands on HazCom

As new equipment moves to A2L refrigerants like R-32 and R-454B, technicians are now working with refrigerants classified as mildly flammable — a real change from the non-flammable refrigerants most crews trained on. That doesn't just change how you handle and store them; it changes the paperwork. The safety data sheet, the label, and the training record for those refrigerants have to reflect the flammability hazard. It's the kind of update that quietly falls behind when the SDS lives in a binder in a truck.

What the software actually gives you

Pricing for one shop, or a multi-branch contractor

SDSentry is a flat $24 per location per month with no document cap, so a busy shop stocking dozens of chemicals costs the same as a small one. There's a 7-day free trial (card required, no charge until it ends), and a free SDS search with no signup to check coverage first.

If you run more than one branch, a per-location tool works in your favor: one account covers the written program, SDS library, labels and training for every branch, and larger contractors pay less per added location. A multi-branch contractor getting ready for the 2026 deadline handles all of its shops from one place rather than a separate binder at each.
