At this point, if your R-22 unit still needs work, the technician you hire will need to source their recycled freon. R410A is much more energy-efficient than R22 too. It is an offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (the Act) to manufacture or import equipment that is charged with a chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC) refrigerant, or designed to operate solely using a CFC or HCFC refrigerant. What is the impact of illegal refrigerants. However, replacing the unit is not legally required on your part. The majority opinion is that HFO refrigerants are the future, and for automobile applications 1234YF will be the new go to.

Wholesalers that sell refrigerant for resale are legally responsible for ensuring that their customers fit into one of the categories of allowed purchasers under the sales restriction. 0000047519 00000 n
Sales, distribution, or import for use in California of refrigerants with GWP > 1500 is prohibited starting in 2022. . If you have purchased a newer home AC unit, you probably dont need to be concerned. The use of CO2 in MVAC systems must adhere to the standard conditions identified in SAE Standard J639 (EPA 2012b). R410A refrigerant is not currently being phased out. Click here for a list of acceptable substitutes to replace banned HCFCs. The sales restriction covers refrigerants contained in cylinders, cans, or drums, except for the sale of small cans of substitute refrigerants (e.g., R-134a for use in motor vehicle air conditioners). Remember, you mustnt put the wrong refrigerant in the system. Allen, J. Boschung, A. Nauels, Y. Xia, V. Bex and P.M. Midgley (eds.)]. It is the wholesaler's responsibility to determine whether persons who claim to represent a refrigerant purchaser are indeed authorized representatives. Some suppliers have been known to ask for a certification purely for purchase. The heat from the food in the refrigerator is then absorbed by the cool, liquid refrigerant. This is because it is far better at being able to pull the heat out of the air. January 1, 2030. First of all, lets break down why R-22 is being eliminated in the first place. 0000000016 00000 n

New stand-alone medium-temperature units with a compressor capacity equal to or greater than 2,200 Btu/hr and stand-alone medium-temperature units containing a flooded evaporator: FOR12A, FOR12B, HFC134a, HFC227ea, KDD6, R125/290/134a/600a (55.0/1.0/42.5/1.5), R404A, R407A, R407B, R407C, R407F, R410A, R-410B, R417A, R421A, R 421B, R422A, R422B, R422C, R 422D, R424A, R426A, R428A, R434A, R437A, R438A, R507A, RS24 (2002 formulation), RS44 (2003 formulation), SP34E, and THR03 as of January 1, 2020. The solution that would allow CFCs to be phased out is HydroChloroFluoroCarbons, also known as HCFCs. Like the ozone-depleting substances they replace, most HFCs are potent greenhouse gases with very high global warming potentials (GWPs). HVAC.com can help grow your business by introducing you to new customers in your local area for free! This formula does not work with zeotropic or azeotropic blends.

The regulations on refrigerant phaseouts in Canada and the USA are similar. The commonly-used high GWP refrigerants R404A and R507A are also included in a list of 24 refrigerants which will be deemed unacceptable for use in new retail food refrigeration (refrigerated food processing and dispensing equipment) from January 1, 2021. The cost of R410A is just a fraction of the cost of R22. 2. The acceptable alternatives list is evaluated by the EPA and revised as necessary as alternatives become available for specific applications.

R-22 refrigerant was made in the late 1990's to temporarily replace R-12 due to its lower ODP. This means it is getting close to the end of its lifespan. What you need to know when HCFCs contain some chlorine, but a much lower amount than CFCs, making them more environmentally friendly. They ban production and imports of R-22 and R-142b for new equipment starting in 2010, but allow their continued The most common alternative refrigerant to R-22 is R-410A, which is sold under various names, such as GENTRON AZ-20 , SUVA 410A, and PURON . At the very least, its going to be increasingly expensive. The United States Environmental Protection Agency and other groups and agencies throughout the world established a commitment to phasing the material out. Do not expect air conditioners, at least those on the more affordable side of things, to be using R32 any time soon, though. The question is what will be replacing R-134a refrigerant? There are several reasons why we are starting to see systems convert to R410A. As you may well know, in the past, certain refrigerants were being phased out.

This means that it is no longer being produced. The illegal refrigerant trade makes use of non-recyclable canisters, making them instantly recognisable by buyers. At the moment, you can expect to pay between $4 and $10 per pound for it. Canisters must be recyclable. If you have an R22 air conditioner, it will probably be in your best interests to swap it out as soon as you can. We are inviting the best HVAC contractors in the industry to joinour network so you can connect with customers who need help with their HVAC system. If you own an air conditioner manufactured before 2010, you may notice that it uses a refrigerant known as R22. Therefore, nothing would happen. The HFO refrigerant R1234yf, designed as a replacement for R134a in car air conditioning systems, is extended for use in newly manufactured medium-duty passenger vehicles, heavy-duty pickup trucks, and complete HD vans. Inhaling can result in dizziness or headaches. However, it needs to be operated at a far higher pressure than R22. 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 indicatingthat he or she is purchasing the refrigerant only for eventual resale to certified technicians. You need to get it right. The purpose of a refrigerant is to help absorb the heat from the air that flows through the air conditioner. Others include R407C and R410A, as well as a number of interim "drop-in" blends. In fact, in some areas of refrigeration, this has already begun. 0000047669 00000 n
During the comment period associated with this ruling, several questions were posed which prompted the EPA to issue clarifications. xref
