What Will Happen to R22 and How it Affects You

May 17, 2016

If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably read up. R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it’s certainly incredibly critical. Most air conditioning units older than 10 years use an AC refrigerant called R22 that’s commonly identified as Freon*, and is stated by the EPA as HCFC-22. In this blog, we’ll use the name R22. This refrigerant was introduced in the 1950s and became the predominant AC refrigerant in the residential heating and cooling industry.

The Montreal Protocol

Moving ahead a few decades the world realized that R22 refrigerant was aiding in the depletion of the Earth’s ozone layer. Not cool. So, the U.S. EPA, in cooperation with other agencies and groups around the world, started a phase out of many ozone-depleting agents as part of an international agreement known as the Montreal Protocol. The regulation lists many HCFCs and CFCs (different types of refrigerants that deplete the ozone layer), but R22 is considered one of the worst offenders.

Timeline and R22 phase out progress in 2018

In 2003, the phase out of R22 production and imports began. By the start of 2010 the production and import of R22 was reduced. However, servicing current, existing equipment is still permitted while there is an available supply of R22. To guarantee the public’s compliance with the new law, all sales of R22 must be purchased by a certified technician R22 refrigerant will be obtainable to service existing air conditioners after 2020.


R22 consumption allowance during phase out period

The graph above shows the EPA’s consumption allowance of R22 by percentage. The limits on R22 consumption were implemented in 2010 and follow a declining trend until 2020.

So how does this affect prices?

If you’re thinking that this sounds like a great case study for an economics professor teaching supply and demand, then you are on the right track. As you can imagine, older air conditioners more often have leaks and need repairs. Any systems that are older than 2010 are more likely to use R22, which means there’s a lot more demand for it, and a reduced supply. Prices have only gone up due to scarcity.

Recall that in order to buy R22, you must be an EPA-certified technician. So, the typical homeowner can’t purchase a cylinder themselves. Also, there are some firm regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This expense is passed on to the homeowner as companies have to cover the increased overhead related to R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing units.

So, what does this mean for you?

The cost of R22 is considerably increasing because of the declining supply, and new refrigerant will no longer be available for use at all after 2020, with the exception of recycled quantities.

If you’re thinking, “Holy cow, this is starting to sound expensive,” you’re correct, it is. This is why when our technicians come out to assess your unit we make sure to see what refrigerant your unit uses, and in many cases, we’ll advise an upgrade due to the increasing cost of maintaining an R22 air conditioner.

How do I know if my unit uses R22?

If you have an air conditioning system that was built before 2010, your AC will likely have R22. However, if you installed your air conditioner after January 1, 2010, then your unit may not have R22. You can see the type of refrigerant your system runs on by checking the appliance’s nameplate. This nameplate is usually found on the outdoor condenser of your central air conditioning system. If you can't find it, you can grab your user’s manual. Otherwise, you can call your local Service Experts center. If you have a maintenance agreement with us, we also have your information on hand and a tech can let you know immediately if your unit uses R22.

Instead of Freon, use Puron

The industry has changed from R22 to R410a, which you may recognize by the brand name Puron. In the remainder this article, we’ll use the name R410a (although Puron is a well-known brand, there are other companies that make R410a). There are some key benefits to switching from an R22 air conditioning unit to one that uses R410a. It offers a higher safety rating tests than R22.


R22 drop-in replacement quote

The truth about “drop-ins” is that there is no “drop-in” solution where you simply swap out the refrigerant.

You may have read about “drop-in” replacements for R22. We strongly advocate against this choice. Normally a homeowner who is uneasy about the cost of replacing their air conditioner seeks out an alternative, and this sounds like an easy solution. It often costs the homeowner more money, and almost always voids the manufacturer warranty. The reality about “drop-ins” is that there is no “drop-in” solution where you just swap out the refrigerant. The phrase “drop-in” is referring to retrofitting a air conditioner, which when done right can cost the homeowner as much, or more, money than installing a new unit that uses R410a. In part, this is because different refrigerants work at different pressure levels and demand different parts to run, which results in the technician needing to replace the most expensive components of your system to fit with the new refrigerant. If this crucial step is avoided, your system will quickly stop running, and you’ll need to get a new unit anyway. If you insist on exploring retrofitting, then consult with an HVAC professional to determine your best option.  

Your manufacturer will typically not pay for the parts to make this swap because retrofitting your AC system will likely void the warranty. It’s usually just a temporary fix, but shopping for a new upgraded AC system will probably benefit most homeowners in dependability, satisfaction, and long-term comfort.

It’s better to discuss pricing offers with your HVAC provider if you’re concerned about cost. At Service Experts Heating & Air Conditioning, we have financing available that makes a replacement affordable, and we monitor for any manufacturer and utility rebates that would make it easier to swallow an unforeseen replacement. To avoid an emergency on a hot day, many of our customers choose to do a pre-emptive replacement, and replace an old AC before it doesn’t work. If you’re thinking the same thing, then you’re in good company!

If your unit was built after 2010, you’re probably safe

If your heating and air conditioning system was built after January 2010, the R22 phase out problem may not apply to you, because it’s likely that your system uses the new, approved replacement refrigerant, R410a. However, air conditioners installed after 2010 might use R22, so it’s best to check with an HVAC Expert. You can always check for this and the refrigerant type by checking the nameplate on your condenser (the condenser is the outside unit).

What do I do if my air conditioner uses R22?

To review, if your HVAC equipment was produced prior to January 2010, particularly if it’s older than a decade, you have a few options:

  1. Purchase an upgraded, more environmentally-friendly system that uses R410a.
  2. Contact an expert to replace the parts in your current AC system to help make it compatible with an approved air conditioner refrigerant. This is not advised.
  3. Remain using recycled R22 and burn through costs like it’s the ozone layer.

To be clear, the EPA regulates the production and use of this refrigerant, but not your unit. The law doesn’t require you to replace your air conditioner. Eventually, your AC will not work and it will need to be replaced, and only R410a units will be available for sale.

The best option is to get a new, upgraded air conditioner, particularly if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has lots of financing options that help with your budget, and again, we look out for rebates from HVAC manufacturers and local utilities to make it easier on you. New AC equipment will also be more efficient and present you superior comfort, helping to lower your energy costs.



You could also select the status quo and continue using recycled R22 air conditioning refrigerant for the time being. While this sounds like a nice alternative, the expense of servicing old R22 A/C systems is starting to surpass several hundred dollars (easily a down payment on a new system). You may also see the prices grow as demand continues to rise on a substance that is no longer produced or widely available.

If you aren’t aware of what type of AC refrigerant your air conditioning system uses, we can help. Contact Service Experts Heating & Air Conditioning today and we can provide an inspection to find out if you are currently using R22 and, if so, what’s the best next step.

The good news

While making the transition to an approved AC refrigerant may intimidating, it’s helping to save the ozone layer. These regulations will help guard the ozone layer in the Earth’s atmosphere, which helps block radiation from the sun and prevents serious illnesses, such as skin cancer. It’s not far-fetched to say that you, as a homeowner, are a grand part of this by replacing an old R22 unit with a newer, ozone friendly unit.
