Buy R421a Refrigerant



The refrigerant blend came into existence at a time when governments had signed a treaty to eliminate ozone-depleting refrigerants. Although R22 had a low impact on the ozone layer, the little amounts that sneaked into the atmosphere caused damage to it.

Experts agree that although R22 harmed the ozone layer, it was efficient. In fact, none of the replacements in the market have been able to come to its level in terms of efficiency and system performance. Therefore, even though R421A might be a good retrofit, the chances are that your system might end up overworking to cool your space once you charge the system with the refrigerant. Sometimes, the system might fail to work at the same level as when using R22.


Please note that Environmental Protection Agency law requires certain individuals to be licensed before purchasing some refrigerants. You will be required to provide your certificate number or declare the item will be resold to an EPA certified technician on certain types of Refrigerant. (R-410A, R-404A, & R-134A are excluded from this.) This helps us keep compliant and prevents any and all future headaches for you or your company down the road.

The sales restriction is established by EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act. Only EPA-certified technicians are allowed to purchase ozone-depleting substances (ODS) or non-ozone depleting substitutes used as refrigerants, with limited exceptions. Refrigerant can only be sold to technicians certified under the Section 608 or Section 609 technician certification programs, where individuals may only purchase refrigerant consistent with the appliances covered by their certification.


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). This sales restriction does not cover refrigeration and air-conditioning equipment or components containing refrigerants.


Only Section 608 certified technicians can purchase refrigerants intended for use with stationary refrigeration and air-conditioning equipment. Section 609 certified technicians cannot purchase refrigerants that are intended for use with stationary equipment, regardless of container size.


Small cans of non-exempt MVAC refrigerant (i.e., containers designed to hold two pounds or less of refrigerant) that have unique fittings, and self-sealing valves can continue to be sold to persons without certification for DIY use on their vehicles.


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. 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.


If a wholesaler knows that refrigerant delivered to a purchaser when no one is present will ultimately be received by the purchaser or his authorized representative, then the wholesaler may deliver the refrigerant without obtaining the signature of an authorized representative.


A little background R-22 ( Freon) was the popular refrigerant up to around 2010. Pre-2010 you will find R22 on some systems but many were starting to move over to the replacement refrigerant R-410A. In 1987 there was an agreement called the Montreal Protocol. This agreement established requirements that started the worldwide phase-out of ozone-depleting CFCs (chlorofluorocarbons) which the refrigerant R-22 (HCFC-22) is part of. In 2020 (just 3 years away) there will be no production or importing of HCFC-142b and HCFC-22, so all that will be available is what is reclaimed or recycled.


Another option for repairs on older R-22 systems is R-421A. This is a replacement refrigerant for R22 without unit modifications of the system and does not contain hydrocarbons, such as Butane, Isopentane or Isobutane. ( -08.pdf )


It became illegal to produce or import virgin R22 in the U.S. on Jan. 1, 2020; the refrigerant, however, is still readily available, legal to use, and its price has remained fairly stable. HVAC Contractors servicing existing R22 systems should have no trouble finding the refrigerant, as industry experts say that existing stocks of virgin and reclaimed refrigerant should be available for a long time.


For customers who still have R22 systems, it is important that they understand what the phaseout means. This does not mean scaring them into thinking they need to replace their HVAC systems right away; let them know instead that in case they have a leak, the cost may go up to replace the refrigerant in their system.


If an R22 system is inefficient, causing discomfort, leaking, and/or requires a major repair, it may be best to talk with customers about replacing it with a new system that uses R-410A. Remember that this can be a costly proposition for homeowners, many of whom may not have purchased a new system in years (or at all) and will likely be surprised at the cost. They should, however, understand that a new system not only uses a more environmentally friendly refrigerant, it will also be more energy efficient, likely offer better comfort, and come with a multi-year warranty to ensure peace of mind.


Jason Ellington, a contractor in Rockledge, Florida, has not offered virgin or reclaimed R22 for several years due to his concerns about the environment, as well as price fluctuations of the refrigerant. Most of his customers use R410A, but when a customer still has an R22 unit, he suggests retrofitting it to what he considers to be a more environmentally friendly refrigerant.


Even though it is no longer legal to produce or import virgin R22 in the U.S., there is no reason for you or your customers to worry. Take the time to educate them about the phaseout; help them decide whether it makes sense to repair or replace their R22 unit; encourage them to purchase a maintenance contract to keep their system running smoothly; and consider alternative refrigerants if a more environmentally friendly solution is desired. If you have any questions about alternative refrigerants or the availability of R22, check with your local Ferguson HVAC.

You never realize how much you appreciate your AC until you do not have it. One of the most common problems with an AC unit is the need to recharge the refrigerant. Luckily, AC recharge is only required if there is a leak. If the AC needs a recharge, the unit only blows warm air, but it will be a gradual change. By the time you notice there is a problem, your house is already hot. If the only problem is adding the refrigerant, the cost will be much lower. While the cost of new air conditioners is going up in 2023, costs for recharging should remain stable, except for recharges containing Freon and some other scarce coolants like R410A, which will no longer be used in new systems in 2023. As Freon and R410A become scarce, costs will rise. However, newer alternatives for these coolants are increasingly available at lower costs.


Three basic AC units are available: window, central AC system, and split AC system. The average cost of recharging a home AC unit after a leak ranges between $100 and $600, depending on the unit type. While AC unit refrigerant leaks are very common, the prices for a recharge vary depending on the unit. Because R22 refrigerant, also known as Freon 1, is banned for production and importation in the United States, it has become significantly more expensive to recharge R22 air conditioning units since 2020. Even AC units that do not take R22 can be pricey because the cost of an HVAC recharge or heat pump 2 refrigerant charge can be inflated to cover various expenses. Understand the current pricing for coolant so that you do not pay more than the market price.


Refills are only needed if there are leaks or damage. Because of this, the refill service is usually performed with other AC repairs like coil or line replacements. In most cases, it takes 5 to 10 minutes to fill 1 pound of refrigerant. A 2.5-ton HVAC unit that requires 5 to 10 pounds would take about 25 minutes to 1 and 40 minutes. By law, all AC recharging must be done by a professional. This law is part of the EPA section 608 of the Clean Air Act. The unit age is not a determining factor in the time needed.


Some AC units have minor leaks and require refrigerant replacement. Others may only need a small-top off or recharge, while some need a full replacement. The coolant amount that needs replacing and coolant type impact your final costs. The full cost to replace refrigerant in an AC unit is $100 to $1,800 based on the coolant and unit type and length of the refrigerant lines. The home AC refrigerant recharge that still runs on R22 is even more expensive, given the lower available supply of R22 coolant. Replacing R22 coolant costs $50 to $80 per pound. You can change from R22 coolant to a less expensive coolant, provided your technician is willing to do so, and remember to recycle the R22 responsibly.


Today, most homeowners are familiar with Freon (also known as R22), a colorless, non-combustible gas that acts as a refrigerant. Depending on the refrigerant type, the price of coolant for an air conditioner ranges from $4 to $80 per pound. Although Freon may have once been the most popular refrigerant on the market, many other coolants have taken its place in recent years. In 1992, the EPA determined that hydrochlorofluorocarbons were harmful to the environment and began a campaign to eliminate their use. 041b061a72
