Effective January 1, 2018, the United States Environmental Protection Agency (EPA) is requiring that the purchaser of this refrigerant is in possession of an AC certification card (608 certification for HVAC) or a signed resale agreement if the purchaser is purchasing the refrigerant for eventual resale. 

If you are an end user, then you must show evidence that at least one technician within your company is properly certified. 

If you are a wholesaler that sells refrigerant for resale you are legally responsible for ensuring that your customers fit into one of the categories of allowed purchasers under the sales restriction. Although the regulation does not specify precautions that wholesalers must take to verify the intent of individuals purchasing refrigerant, EPA recommends that wholesalers obtain a signed statement from the purchaser indicating that he or she is purchasing the refrigerant only for eventual resale to certified technicians.

Type and Description

Acme-Cool AC-77 Refrigerant is designed for use in R22 systems. Because there is no need to use expensive and hygroscopic synthetic lubricants (POE), the risk of moisture ingress into a refrigeration system is completely avoided. Acme-Cool AC-77 Refrigerant has significantly lower discharge temperatures and pressures than R22 which removes the problem of oil decomposition and improves the coefficient of performance and saves wear on the compressor.


Acme-Cool AC-77 Refrigerant is suitable for use in R-22 residential, commercial and industrial air conditioning and refrigeration systems, and appliances.

Service Work

Because it is a blend, it is recommended that Acme-Cool AC-77 Refrigerant be charged into systems as a liquid as opposed to the gaseous phase. Since there is no need to change the existing lubricant, Acme-Cool AC-77 Refrigerant is straightforward to use, as the following procedure outlines.


Acme-Cool AC-77 Refrigerant is compatible with both mineral and alkybenzene oils found in R22 systems, and also with the polyolester lubricants. Therefore, there is no need to change the lubricant although compressor manufacturers' recommendations regarding lubricity should be followed.

Materials Compatibility

Acme-Cool AC-77 Refrigerant is compatible with all materials commonly used in refrigeration systems. In general, materials which are compatible with R22 can be used with Acme-Cool AC-77 Refrigerant. lt is recommended to check equipment manufacturer's retrofit literature and obtain recommendations from equipment manufacturers with regard to materials' compatibility.

Environmental Data

None of the components of Acme-Cool AC-77 Refrigerant contains chlorine so that it has no ability to deplete the ozone layer.

As with all hydrofluorocarbons (HFCs), Acme-Cool AC-77 does have a direct global warming potential (GWP), but this is counterbalanced by its lower Total Equivalent Warming Impact (TEWI). Tests have shown that Acme-Cool AC-77 has a higher Coefficient of Performance (COP) than R22 in a range of applications including commercial refrigeration systems and heat pumps, both in the heating and cooling mode.



Frequently Asked Questions:

Q: Can I top off my system?  Can I mix refrigerants?  Do I have to evacuate my unit

A: Mixing refrigerants is ILLEGAL in North America. EPA regulations require that an Air-conditioning system be properly evacuated of refrigerant by a certified professional before replacing your refrigerant.

  1. great alternative to R-22 5 Star Review

    Posted by on 9th Aug 2015

    Converted my heat pump system from R-22 due to a slow leak. Cost effective alternative to the expensive R-22. System now seems to run quieter and less frequently. Hot Texas 100+ degree summer has put it to the test and passesd.

  2. Worked as advertised 5 Star Review

    Posted by on 6th Aug 2015

    Had professionals install freon. I obtained MSDS and comparison data between R-22 and R242a (RS44) to assist installers, as they had no data on this new gas. All went well. I think the pros purged the R-22 before installing the new stuff, even tho product literature said the 2 gases were compatible.
