R-22 (Submarine No. 99) was laid down 19 April 1917 by the Lake Torpedo Boat Co., Bridgeport, Conn., launched 23 September 1918, sponsored by Mrs. Frie A. Eklund; and commissioned 1 August 1919, Lt. Comdr. Walter S. Haas in command.

Following commissioning, R-22 operated in the New London-Newport area for 2 months. On 1 November, she headed south for Coco Solo, C.Z., her homeDort. Designated SS-99 in July 1920, she was based in the Canal Zone with Submarine Division 1 through that year. The following year she was transferred back to New London for duty with Submarine Division 0, an experimental division. She was based at New London for the rest of her active service, returning to Panama only for the 1923 Fleet Problem. Ordered inactivated in 1924, she was towed to Philadelphia in November and decommissioned there 29 April 1925. Five years later, 9 May 1930, she was struck from the Navy list. She was sold for scrapping in July of the same year.

Know This Before You Purchase

Now before I get into the price per pound information you should first understand the R-22 market and your R-22 air conditioner a bit more. The first point of note is do you have an R-22 system? The only way you can be exactly sure is by looking at the outside section of your air conditioner. There should be a white sticker located somewhere on the machine. This sticker will indicate exactly what kind of refrigerant your split-system is taking. If you are in the United States then the chances are that it will be one of two refrigerants. If the unit was manufactured and installed before 2010 then the chances are high that it takes R-22. However, if the system was manufactured after 2010 then it most likely takes the HFC R-410A. Again, it is always best to check for the sticker to identify exactly what kind of refrigerant you are dealing with.

R-22 Phase-Out

You may have noticed from my section above that the year 2010 is significant when it comes to R-22. Well folks, that is because there was a mandatory phase-down implemented by the Environmental Protection Agency that started in 2010. You see, as of January 1st, 2010 no new R-22 machines could be manufactured or imported into the new United States. (This excludes ‘dry systems’ which could be manufactured as long as they didn’t contain R-22.) At the time of this phase-down nearly every home and office air conditioner in the country was using the HCFC R-22. Yes, there were some exceptions here and there… but for the most part the country ran on R-22.

The phase-down was put in place due to the damage that R-22 caused to the Ozone layer. R-22 contained the chemical known as chlorine and when R-22 was leaked or vented into the atmosphere that chlorine made it’s way up to the Stratosphere and eventually into the Ozone. The chlorine would then eat away at the Ozone layer causing damage and the eventual formation of a hole above the arctic. As most of you know, back in the 1980’s a treaty was signed by over one-hundred countries known as the Montreal Protocol. This treaty aimed at phasing out Ozone damaging substances around the globe. The first to go was the refrigerant known as R-12. There were other phase-outs over the years but the last one, which started in 2010, is R-22.

The phase-down from the EPA was a staggered approach. There was a production and import limit installed in 2010 and then there was another one in 2015. The last one, which is coming up here in just a few weeks is January 1st, 2020. When that date hits R-22 will no longer be able to be produced or imported within the United States. The only way to get your hands on R-22 refrigerant from then on is either through stockpiles of refrigerant that distributors bought up on before the phase-out, by using reclaimed R-22, or by using an R-22 alternative product.

R-22 Pricing Variables

Starting in 2010, when the phase-down began, the pricing of R-22 has been anything but consistent. In some cases it can change wildly from month to month. There are a number of reasons for this but there are a few main drivers that cause the price to go haywire. The first is the basic concept of supply and demand. The more supply out there then the less the price will be. The more demand the higher the price. The other reason is speculation. This is a common term when people discuss the price of oil. Speculators drive the price up or drive the price down. These speculators are folks trying to make a profit based on the rising and falling tide of oil prices.

For those not in the industry I like to compare refrigerant pricing to that of oil. You always hear of oil prices changing day to day. You always hear of speculators and supply/demand issues. Refrigerant is the same way. Since the phase-down started in 2010 we have seen R-22 prices go from a high of twenty-five dollars a pound all the way to nine dollars a pound. That twenty-five dollars per pound was the highest price point that I have seen and that occurred in the summer of 2017. The reason this got so high is that everyone was buying as much R-22 as they could in preparation for the upcoming 2020 phase-out. Because everyone had the same idea of buying up early the price continued to rise and rise.

A lot of folks thought that the price would stabilize at that twenty-five dollar mark. Others thought it would go even higher. Many companies bought up thousands or millions of dollars worth of R-22 in anticipation of an even higher price. Well folks, the inverse happened. After the summer season in 2017 the price on R-22 started to drop. And drop it did. Over the past few years R-22 has been the lowest it’s been in years. Throughout the summer of 2019 R-22 was pricing around ten dollars a pound. In some cases, like right now, it’s around nine dollars a pound.

No one knows for sure what will happen to the pricing when January 1st, 2020 arrives but a lot of the articles I have read predict more of the same. That same price of around nine or ten dollars a pound. This is due to the overwhelming amount of stock-piles out there still.

Age of your R-22 Unit

Before you consider repairing your R-22 system you should ask yourself a few questions. The first is exactly how old is your air conditioner? Is it over fifteen years? If so, then it may be time to look at purchasing an entirely new system that uses the newer refrigerant known as HFC R-410A. I say this for a couple of reasons. The first is that most air conditioners last between fifteen to twenty years. Once you hit that fifteen year mark you are also going to start running into repairs. It could be that your compressor goes out, a capacitor is blown, or a whole host of other reasons.

Whatever happened, your air conditioner isn’t cooling and you need a repair. If the price on R-22 is on a higher upswing then you could risk paying a substantial amount just to repair your unit. Remember, that you have to pay for the repair AND the refrigerant as well. So, say your compressor needs replaced. That could be a two to three-hundred dollar repair. Factor in the refrigerant recharge of about twelve pounds of refrigerant at twenty dollars a pound then you’re looking at a repair bill of around five-hundred and forty dollars.

The question that you will have to answer is are you ok with paying that repair bill? Remember, that your unit is older and with each passing season you are going to have more and more repairs come up. The alternative is spending three-thousand or so and get a brand new 410A air conditioner. While this is a big expense upfront it does prevent you from having a future headache of yearly repair bills.

R-22 Alternatives & Reclaim

Continuing on with the above section if you find that the cost to purchase and install a whole new system at your home or office is too expensive then there are some other options available. If the price of R-22 is high during next year’s summer and you’re looking at possible twenty or twenty-five dollars a pound then there are some alternative choices. The first is what’s known as reclaimed refrigerant. Reclaimed refrigerant is R-22 refrigerant that was used in another machine at one point in time. The used refrigerant is extracted from that machine, put in a recovery cylinder, and then sent to an EPA certified reclaimer. The reclaimer removes any impurities or containment from the used refrigerant. When they are complete the refrigerant is clean and able to be used again.

Many technicians frown on the use of reclaimed refrigerants. I’m not exactly sure why this is as these reclaimers have to go through a rigorous inspection process by the EPA. These guys know what they are doing. The only reason I can see for the skepticism is similar to when you take your car to the dealership. The dealership will ask you if you want new or remanufactured parts. Most folks buy new as they’re not comfortable with a remanufactured. I’ve never had a problem with buying reman/reclaim but that decision will have to be up to you. There is savings involved so that could perhaps be your deciding factor.

Along with reclaimed refrigerants there are a number of alternative refrigerants to R-22. At this time I believe there are over one-hundred different alternatives out there from all different companies and manufacturers. Each alternative is different as well. Some of these products may require very little retro-fit to get the alternative refrigerant to work in your R-22 based system. Others will require a complete overhaul on your machine to get it to work with an R-22 alternative.

Alternative refrigerants are cheaper… as long as R-22 is at or above eleven dollars per pound. If it is lower then that, like it is today, then alternatives won’t do you much good. After all, why pay for an alternative product if you can get the real thing at the same price… or even at a cheaper price? However, if you see R-22 prices going up and up again then alternatives are a great choice for those of you who don’t want to purchase a whole new system.

You Are Paying For Expertise

Ok folks, so the information that I am going to give you in our ‘Price Per Pound’ section is very nearly, if not exactly, the cost that your contractor is paying for their R-22 refrigerant. What that means is that you can expect a markup. After all, the technician and the HVAC contractor need to make money as well. This is a specialized trade and requires trained expertise in order to succeed in. Thinking that you can do this yourself is never a good idea as there are a lot of intricacies that need to be accounted for. As an example, let’s go through and ask a few simple questions that a technician would either have to do or consider:

    • Do you know how to flush your system?
    • Do you know what refrigerants can be vented?
    • Do you know what the Superheat and Subcool are for R-22?
    • Are you 608 certified with the EPA to handle HCFC refrigerants?
    • Do you know how to find, let alone fix, a refrigerant leak?

    All of these questions and more are what you are paying your contractor for. Remember that they need to make money too, but there is also a fine line between having profit and gouging. Reading this article, and reviewing the price per pound, will allow you to be educated and give you the power to negotiate the price of refrigerant.

    Your AC Unit is a Closed System

    Even before you have a contractor come to your home and look at your air conditioner you should be aware that air conditioners are what’s known as closed systems. What that means is that the refrigerant in your air conditioner moves back and forth between different cycles and it, in theory, never runs out or needs refrigerant refilled.

    If you find that your unit is low on refrigerant or is completely out do NOT just refill your machine with a new refrigerant. I repeat do NOT do this. Your system does not need a top off. It does not need just a little bit more refrigerant to get by. No. If you are running out of refrigerant that means that somewhere in the refrigerant cycle there is a leak. Your unit is leaking refrigerant and will continue to leak refrigerant until a repair is made. If you dump more refrigerant into it without fixing the leak you are literally throwing money down the drain. Potentially a lot of money too if yours is an R-22 unit.

    I like to think of it as a above ground pool. If you get a puncture in the pool lining water will leak out. Sure you can always add more water but it’s not fixing the problem. Adding more refrigerant doesn’t fix the problem either. It’s just prolong the inevitable and wasting money.

    What's a Fair Price for R-22 Refrigerant?

    We’ve recently had a lot of questions from homeowners regarding the price of refrigerant—R-22 refrigerant, to be exact.

    The bottom line? It’s pricey. In fact, the average price to “recharge” your AC unit with R-22 refrigerant is around $615–$750+.

    And that’s the average market price for R-22 in Denver—with very similar prices across the US (2018 prices, at least). That’s not us price-gouging or taking advantage of customers—unfortunately, the price range is out of our control.

    But either way, we know that’s not an easy bill to stomach. And we know that you have lots of questions, like:

    Why is R-22 refrigerant so expensive?

    Do I really need more refrigerant in my AC?

    Is R-22 my only refrigerant option?

    So stay tuned. We’ll answer all those questions—and more—below.

    Need an estimate for your AC refrigerant recharge? We’ll give you a quote for free.

    Why is R-22 refrigerant so expensive?

    R-22 refrigerant is so expensive because there’s such a limited supply of it left.

    You see, R-22 is an “ozone-depleting substance” and is extremely harmful to the environment. Because it’s so dangerous, countries around the world have been slowly phasing out this refrigerant since 2010. According to the EPA, all sale/production/import of R-22 will end completely in 2020.

    In the meantime, R-22 prices have gotten higher and higher every year—and will only continue to get higher.

    It’s simply a matter of “supply and demand”: a lot of air conditioners still use R-22 but there’s very little R-22 available for them. That said, let’s look at why and when a central air conditioner might need R-22 in the first place.

    Do I really need more refrigerant in my AC?

    This is a smart question because, unfortunately, there are some techs out there who may tell you that you need refrigerant when you really don’t.

    Here’s what you need to know: The only reason you would ever need a refrigerant recharge is if you have a refrigerant leak.

    So if you ever hear a tech say that you need a “routine” refrigerant recharge, they’re just out for your money. Related: How Often Does A Central Air Conditioner Need Refrigerant?

    To explain, refrigerant doesn’t get used up in an AC like gas in a car. Instead, it travels through the system in a closed loop. So, unless there’s a hole somewhere along the refrigerant components, you should have the same amount of refrigerant from the AC’s installation to its death.

    Refrigerant cycles throughout your unit in a closed loop and never gets used up.

    You’ll know you have a refrigerant leak if you notice:

    Hissing noises along a certain point of the refrigerant lines

    Ice along the refrigerant lines (or a completely frozen indoor/outdoor unit)

    Warm air/no air blowing from AC vents

    The AC can’t cool your home to your desired temperature anymore

    If you think you have a refrigerant leak based on those signs, contact a professional to inspect your AC. If they find refrigerant leaks (which they should point out to you), you'll want to make sure your tech repairs the leak BEFORE recharging the system.

    Is R-22 my only refrigerant option?

    If your current AC unit runs on R-22, then yes, that’s the only refrigerant that will work for that unit. Trying to add a different type of refrigerant into an R-22 unit will cause the unit to die soon after it starts running.

    So if you were told that you have a refrigerant leak, you really have two options:

    Pay for the recharge and stick with your R-22 unit

    Switch out your AC unit for a unit that runs off of R-410A (EPA-approved refrigerant)

    Yeah, we know that 2nd option sounds crazy expensive but if your AC unit runs on R-22 it’s likely nearing the end of its lifespan so it makes sense to replace the unit now. You see, most R-22 units that are still functioning are nearing 10+ years old, which means they’re likely to start needing frequent repairs or will die altogether soon.

    We suggest choosing a replacement AC unit that runs on R-410A refrigerant. This refrigerant is approved for use in residential air conditioners and is much cheaper than R-22. Most Denver homeowners with older R-22 units will go ahead and make the switch to an R-410A if they ever get a refrigerant leak—it’s just the more cost-efficient option.

    History of R-22

    Most of you may not read this section of the article but I have always been fascinated by history rather it’s world history or if it’s just the history on a refrigerant like R-22. Everything has a story and it is always fun to learn something new.

    The Beginning

    R-22 can trace it’s roots back all the way to the 1920’s and 1930’s. It, along with R-12 and R-11, were one of the very first ‘modern’ refrigerants. These refrigerants known under the classifications CFC and HCFC were a first of their kind. They were non-flammable, non-toxic, and were efficient. They answered all of the requirements for the ‘perfect’ refrigerant. These new classes of refrigerants were registered under the now famous DuPont brand name known as Freon.

    These refrigerants were originally invented by a joint partnership of General Motors and the DuPont corporation in the late 1920’s. The mass production of R-22 began in the mid 1930’s and exploded from there. When the 1950’s and 1960’s R-22 was found in nearly every home, office, super-market, and industrial area. technicians started and end their whole careers just dealing with R-22 refrigerant. That’s nothing like it is in today’s world. Nowadays you have a new refrigerant coming out every few months.

    The Ozone

    All was not perfect with this explosive growth of CFC and HCFC usage across the world. As the decades wore on and the growth continued scientists began to notice a startling effect of these refrigerants. It was in the 1980’s that a team of scientists out of California realized that all of the Chlorine that was in CFC and HCFC refrigerants were causing damage to the Ozone layer. When vented or leaked the refrigerant would drift up and into the atmosphere. It is there where the Chlorine would do it’s damage. Eventually it got so bad that a thinning of the Ozone layer began to form over the Arctic. The scientists noticing this sounded the alarm and the world’s governments took action by creating the Montreal Protocol.

    The Montreal Protocol is a treaty that was signed in the late 1980’s by more then one-hundred countries. It’s goal was to rid the world of using Ozone depleting substances like CFC and HCFC refrigerants. This treaty was enacted in countries all over the world. The first target was CFC refrigerants such as R-12. In 1992 R-12 was phased out of the automotive market in the United States and was replaced with the newer HFC refrigerant known as R-134a. R-134a had the benefit of not containing Chlorine so with its usage there would be no danger to the Ozone layer. The next refrigerant to go was the CFC refrigerant known as R-502 in the mid 1990’s. As time went by there were other CFC and HCFC refrigerants phased out but the big change didn’t happen until 2010.

    In 2010 is when the phase out of the ever popular HCFC R-22 refrigerant was to begin. At that date no new machines could be manufactured that took R-22 as a refrigerant. This was the line in the sand saying that there would be no more Chlorine containing refrigerants used. While 2010 was the beginning there was a schedule of set dates every five years that would slowly phase out R-22 entirely from the United States. A picture of this phase out schedule can be found below.

    Enter HFCs

    It seemed that the end of R-22 was near. But, what would replace this so widely diverse refrigerant? In 1991 the new HFC refrigerant R-410A was invented by the Honeywell Corporation. (Back then they were known by Allied Signal.) After invention Honeywell licensed production and manufacturing rights of 410A to other companies but even today Honeywell still continues to lead production and sales of 410A.

    410A saw it’s first use in a residential air conditioning system all the way back in the year 1996. (Hard to believe that was over twenty years ago!) The Carrier Corporation was the first company to introduce 410A into the residential marketplace and during that time they trademarked 410A as their brand name known as Puron.

    While 410A could be found at homes in the early 2000’s it was sporadic. It wasn’t until we got closer and closer to the announced phase out date of R-22 that things began to pick up. Even though we were only a few years away from the phase out date there were still companies who had their heads buried in the sand and hadn’t bothered to train themselves or their technicians on the new technology. You can’t blame them really it’s human nature. The change was down the road and they would worry about it then.

    In 2010 when the change did come into play and no new R-22 machines could be manufactured things began to get real for people. R-410A was the new refrigerant and it wasn’t going away, at least for a while. A lot of the old-timers out there got fed up with it all and decided to retire right around 2010. The younger guys or mid-career guys stuck around and got through the turbulent years. Today, in October of 2017, R-410A is one of the most widely used refrigerants in the world.

    Is R22 Already Phased Out?

    Is R22 already phased out?

    Yes, R22 is already phased out. There are a few ways to get around this, however. If you want to find out how you can still get R22, or R22 replacement refrigerants, then you are going to want to check this out or just keep reading! R22 was scheduled to be completely phased out by the EPA by January 1, 2020.

    What Is An HCFC Refrigerant?

    What is an HCFC refrigerant?

    HCFC stands for Hydrochlorofluorocarbon… R-22, also known as HCFC-22 or Chlorodifluoromethane is the most widely used HCFC refrigerant . Chances are, if you have an AC system over ten years old, you are most likely using this refrigerant!
    As of 1/1/2020, these refrigerants were phased out by the EPA.

    Why Is R22 Being Phased Out?

    Why is R22 being phased out?

    The EPA has deemed that HCFCs are depleting Earth’s ozone layer and has been systematically phasing out these refrigerants with these new refrigerant laws for quite some time now!
    Luckily, there are quite a few R-22 replacement refrigerants on the market that can help you get by until you are ready to replace your air conditioning system. You might want to check into this… It could be a good option for you!

    Why haven’t I heard of the New Refrigerant Laws?

    Well, that’s actually an easy answer! Most people simply haven’t noticed the rising prices until now! You see, the EPA started a 10 year phase out plan in 2010! Every year, manufacturers of HCFC refrigerants like DuPont , for instance, have been forced to scale back production more and more! It may not have been quite so noticeable until recent years, when the price hike really started to sky rocket due to high demand and low supply!
    But don’t worry, if your not in a position to purchase a brand new HVAC system… There is another option!

    Can you still buy R22?

    Yes. While R-22 refrigerant is no longer in production, an extremely limited supply of recycled R22 is still on the market. However, prices are extremely high! If you plan on hanging on to your leaking R22 system, a better option would be retrofitting your system to a R22 replacement refrigerant. Though it may cost a little bit more up front to do, you will save a ton of money on Refrigerant in the future!

    Where can you buy R22?

    Some supply shops still offer an extremely limited supply of recycled R-22 refrigerant to contractors. Though, it is important to note that only contractors or technicians with a valid 608 certification can purchase R-22 refrigerant.
    In most cases, customers are much better off retrofitting their system to an R-22 replacement refrigerant.

    What does this mean for me?

    With these new refrigerant laws, manufacturers will no longer be able make R-22 or any other HCFC refrigerants after 2020 due to the R22 Phase out. So… If it’s already costing you an arm and a leg to top off your Air Conditioner, you can only expect it to get worse. However, their is another solution you might be interested in hearing about!

    What’s A Drop In Refrigerant?

    What is a drop in refrigerant?

    Drop in refrigerants are refrigerants that replace another refrigerant. But don’t stop there, because it’s not a simple as you think.

    This can be a very confusing subject for some to understand, as this term can mean different things to different people. We’ll try to break it down for you, so that you understand the terminology as best as possible.

    Some, think of a “drop in” refrigerant as a refrigerant that can be “mixed” with the refrigerant that is already inside your equipment, such as R-22.

    Others, think of “drop in” refrigerants as refrigerants that are compatible with the original refrigerant designed for your equipment (such as R22), but do however require that the existing refrigerant be recovered and possibly a few extra measures be taken such as an oil change or changing of the liquid line drier before charging the system with the new “drop in” refrigerant. We call this a retrofit!

    Is there a drop in refrigerant for R22?

    Yes, there are many drop in replacements for R22, but you’re going to want to read this before moving forward. Because may not what you think!

    However, there are not any drop in refrigerants available that can be mixed with R-22 at this time.

    Is There A Replacement For R22?

    Is there a replacement for R22?

    Yes, there are R-22 replacement refrigerants available! However, you’ll need to read this first, because it will require some retrofitting of your existing system. Simply put, none of these refrigerants are what some would consider exact “drop in refrigerants” and do require some retrofitting to your existing R22 equipment.

    How much does it cost to retrofit an R22 system to an R22 replacement refrigerant?

    $900.00 to $1,500.00 is the average price we have found among most reputable companies to retrofit an existing R-22 system with an R22 Replacement refrigerant! It certainly can be expensive to do, but it could help you get around the R22 Phase Out by the EPA for a little longer.

    If you live within our Service Area , we would be happy to assist you in retrofitting your HVAC system! Feel free to contact us at (817) 354-5822 to schedule service!

    How To Retrofit An R22 System?

    How to retrofit an R22 system with an R22 replacement refrigerant?

    What your Section 608 Certified Technician will need to do is recover all existing R-22, pull a vacuum on your system and then charge it back up with a new drop in refrigerant like R422D, MO99, R407C or whichever R22 Replacement would be applicable to your system. In some cases, an oil change on your system and the changing of your drier may also be necessary to prevent contamination.
    Of course, there is a cost to retrofitting your system to a drop in refrigerant, but it will save you tons of money in the long run (if you plan on keeping your system that long.)

    Can you use r410A in a r22 system?

    No, you cannot use R-410A refrigerant on your existing R22 equipment. While in some cases it may be possible to use parts of your existing HVAC system, in most cases it is not recommended. However, even if you were to use your existing evaporator coil, air handler or furnace, you would still need to change out your condenser. This is because R410A refrigerant runs at higher pressures and all around has much different characteristics then R22. Your compressor was not designed to use this refrigerant and unfortunately, it just wont work.
    In our opinion, in makes much more sense to replace your system as a whole, but you might be interested in retrofitting your system to a drop in refrigerant. These refrigerants are designed to combat the EPA’s R22 phase out and can take the place of R22 without the need to replace your equipment.

    What Are The New Refrigerant Laws?

    What are the new refrigerant laws?

    IRC M1411.8 and IMC 1101.10 have been put into play in many areas around the U.S., which require that all accessible HVAC refrigerant ports to be secured with tamper-resistant caps! These laws are not associated with the R22 Phase out by the EPA, but could potentially help if your R22 or other refrigerants are being stolen! This will help protect your heating and air conditioning system from theft and would be refrigerant huffers!

    Why were the new refrigerant laws made?

    Originally, these mandates were brought into effect in the effort of reducing the increase of teen air-conditioning refrigerant-related huffing deaths. By now you should already be aware that the refrigerant R22 is currently at the end of it’s life. After 2020, consumers will be forced to upgrade to R410A refrigerant and equipment or use drop in refrigerants! This is because the EPA has decided on 2018 as the last year of the phase out plan . With that said, the current price of R22 is enough to give consumers a serious headache! Since the price hike, there have been countless reports of stolen R22 across the United States! With only an extremely limited supply of recycled R22 available after 2020, we can only expect those numbers to go up!

    Maybe it’s time for you to have tamper-resistant caps installed on your system!

    How do tamper resistant caps work?

    Tamper-resistant caps work the same way your old caps do, except these caps can be opened with a key that only your technician has!

    How much do tamper resistant caps cost?

    We charge $50 for the caps, but the price can vary depending on your HVAC service provider. If you would like to have them installed you can contact us here or call us at (817) 354-5822 to schedule service!

    (It’s important to note that the information in this news report is not 100% accurate. R22 is not the only refrigerant being huffed or stolen! As a matter of fact, even the newer refrigerants, such as R410a are experiencing similar issues! These newer refrigerants are still subject to the same laws!)

    Ask us in the comments below and we will answer it!

    If the condenser and inside coils have to be replaced to accommodate the new freon laws, does that mean the heating unit under the coils has to be replaced also?

    What we suggest is that customers replace the entire HVAC system in most cases. However, if you are on a tight budget, their are other ways to make it work. As long as your evaporator coil (Indoor coil) is rated to handle R-410A refrigerant, you could simply replace your condensing unit (outdoor unit) and your TXV or piston (a Thermal Expansion Valve or piston is the metering device that both regulates the amount of refrigerant entering the coil and flashes it from a liquid into a gas). Since R-410A (the new refrigerant) runs at much higher pressures then R-22 (the old refrigerant), it has to be replaced with the proper metering device, whether it be a piston or TXV.

    The second option would be what is called a “drop in refrigerant”. These refrigerants are designed to mirror R-22 as closely as possible and do not require the replacement of any equipment at all. Your technician would simply have to recover the old R-22 refrigerant, change your schrader valves, pull a vacuum on the system and then recharge the system with your drop in refrigerant of choice.

    Thank you for the comment and hope this helps!

    Hello, I just came across a new refrigerator for sale,the item is using pentane or isopentane as refrigerant.Given the size of the appliance (20 cubic feet) I wonder how much of the gas/liquid charge it contains and what the fire scenario would be in an apartment fire.As I recall there was a horrific fire which destroyed an entire hi-rise building in London England,the ignition source was an overheated refrigerator which lost its charge. I know that isopentane is legal to use as refrigerant in the “green” England.That building is condemned and slated for demolition,last I heard.

    Well in regards to refrigerant being a fire risk, unfortunately many oils commonly used in refrigerant circuits today are certainly still flammable and have caused all sorts of fires in the past. Many things come into play when researching what could be the root of the fire such as amperage to the compressor and other motors. How safe is it? I could not really give you any idea as we don’t typically work on refrigerators. But most of them that I have seen/worked on have been running R-134A refrigerant.

    Cooperation with governments and international organizations has expanded technical assistance for emerging countries to each region and aims for widespread use of the refrigerant R-32 throughout the world.

    Aiming for widespread use throughout the world, Daikin not only manufactures and sells R-32, but it also provides technical assistance in emerging countries in cooperation with governments and international organizations.
    In India, verification tests were conducted for inverter type R-32 air conditioners. In executing training for the proper handling of R-32, the technical level also improved. Consequently, Daikin has received requests from various governments, including the Thai and Malaysian governments, and the company is beginning to target local manufacturers for technical assistance for conversion to R-32.
    Such efforts as those mentioned above have earned Daikin high acclaim and a variety of awards.
