Professional service matters

Start with the equipment—not just the refrigerant name.

Refrigerant systems are designed around specific pressure ranges, lubricants, components and safety classifications. Always confirm the exact refrigerant specified by the equipment manufacturer before charging or servicing a system.

Confirm the refrigerant designation on the equipment data plate.
Use recovery, evacuation and charging equipment suitable for the refrigerant.
Do not mix refrigerants or treat a different refrigerant as a drop-in substitute unless specifically approved.
Follow the product label, SDS, manufacturer guidance and applicable regulations.
Before ordering

A simple three-step compatibility check.

These checks help customers choose the correct product while keeping the page focused on safe, professional refrigerant purchasing.

01 / IDENTIFY

Read the equipment label.

Locate the refrigerant designation, model information and charge data on the unit or in the manufacturer service documentation.

02 / MATCH

Select the exact refrigerant specified.

Match the refrigerant designation rather than choosing based only on cylinder appearance, pressure assumptions or a similar product name.

03 / VERIFY

Confirm service requirements.

Review the SDS, required tools, handling procedures, technician qualifications and any federal, state or local requirements before use.

Product information on this page is intended as a general shopping reference. It does not replace equipment manufacturer instructions, the refrigerant safety data sheet, technician training, certification requirements or applicable laws and regulations.
