Frequently Asked Questions

Helpful information before you order.

Which refrigerant does my air conditioner or heat pump use?

Check the outdoor unit data plate and the manufacturer’s service documentation. The refrigerant designation should be listed there. Do not choose refrigerant from the unit’s age, brand or cooling capacity alone, because different models can use different refrigerants.

Can I replace R22 with R410A in the same system?

No. R410A is not a direct replacement for R22 in an existing system. Have an HVAC professional review the equipment manufacturer’s guidance before considering a refrigerant conversion or system replacement.

Can R32 or R454B be added to an R410A system?

No. R32 and R454B are not drop-in refrigerants for existing R410A equipment. Use them only in equipment designed and approved for the specific refrigerant, with the appropriate service tools and manufacturer procedures.

How do I choose between a small package and a larger cylinder?

First confirm the required refrigerant, then compare the net weight offered for that type. Base the purchase on the service quantity your technician has identified and the number of compatible systems being serviced. A container’s size does not determine a system’s charge.

Will buying refrigerant solve poor cooling?

Poor cooling alone does not confirm a low refrigerant charge. Airflow, controls and other equipment faults can cause similar symptoms. Have the system diagnosed before ordering refrigerant so the purchase matches the actual repair.

Does every refrigerant in the HVAC category fit every HVAC system?

No. HVAC is a broad equipment category. A refrigerant listed here may suit certain systems and be unsuitable for others. Use the exact designation on the equipment label and the manufacturer’s service information to narrow the selection.

What should I check if the refrigerant label is missing?

Find the model and serial number and consult the manufacturer’s documentation or an HVAC professional. Also review available service records for a prior conversion. Avoid guessing the refrigerant from the unit’s age, appearance or an old invoice alone.

What details should I prepare when ordering for several HVAC units?

List the specified refrigerant and planned service quantity for each unit. Group purchases only where the refrigerant designation matches. Review the net weight of each package so the order covers the planned work without confusing package quantity with equipment charge.
