If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably find out more. R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it’s unquestionably incredibly vital. Most air conditioning units older than 10 years use an AC refrigerant called R22 that’s commonly known as Freon*, and is stated by the EPA as HCFC-22. In this article, we’ll use the name R22. This refrigerant was introduced in the 1950s and became the main AC refrigerant in the residential heating and cooling industry.
The Montreal Protocol
Fast forward a few decades and the world realized that R22 refrigerant was aiding in the depletion of the Earth’s ozone layer. Not a great thing. So, the U.S. EPA, in cooperation with other agencies and groups around the world, started a phase out of several 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 believed to be 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 beginning of 2010 the production and import of R22 decreased. However, servicing current, existing equipment is still acceptable while there is an available supply of R22. To confirm the public’s compliance with the new law, all sales of R22 must be acquired by a certified technician R22 refrigerant will be available to service existing air conditioners after 2020.
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 right. As you might assume, older air conditioners may have more leaks and need repairs. Any air conditioners 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 increased due to scarcity.
Don’t forget that in order to buy R22, you have to be an EPA-certified technician. So, the normal homeowner isn’t able to purchase a cylinder themselves. Plus, there are some stern regulations now on how refrigerant is reclaimed and recycled, which adds to the cost. This expense is passed on to the homeowner as companies have to cover the increased overhead associated with R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing air conditioners.
So, what does this mean for you?
The cost of R22 is considerably increasing because of the diminishing supply, and new refrigerant will no longer be available for use at all after 2020, except from recycled quantities.
If you’re thinking, “Man, this is starting to sound expensive,” you’re correct, it is. This is why when our experts come out to assess your unit we check to see what refrigerant your unit uses, and lots of cases, we’ll advocate for an upgrade because of the increasing cost of taking care of an R22 air conditioner.
How do I know if my unit uses R22?
If you own an air conditioning system that was built before 2010, your AC will typically have R22. However, if you installed your air conditioner after January 1, 2010, then your system may not have R22. You can find the type of refrigerant your system runs on by reading the appliance’s nameplate. This nameplate is typically found on the outdoor condenser of your central air conditioning system. If you don’t find it, you can read your user’s manual. Otherwise, you can contact 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 quickly if your unit uses R22.
Instead of Freon, use Puron
The industry has moved from R22 to R410a, which you may identify by the brand name Puron. In the remainder this article, we’ll use the name R410a (although Puron is a familiar brand, there are other companies that make R410a). There are some serious benefits to switching from an R22 air conditioning unit to one that uses R410a. It has a higher safety rating tests than R22.
The truth about “drop-ins” is that there is no “drop-in” solution where you simply swap out the refrigerant.
You may have heard information about “drop-in” replacements for R22. We strongly advocate against this option. Normally a homeowner who is anxious about the cost of replacing their air conditioner seeks out an alternative, and this sounds like an easy solution. It usually costs the homeowner more money, and virtually always voids the manufacturer warranty. The fact about “drop-ins” is that there is no “drop-in” solution where you simply swap out the refrigerant. The phrase “drop-in” is indicating retrofitting a air conditioner, which when done correctly 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 require different parts to run, which means the technician is forced to replace the most expensive components of your system to work with the new refrigerant. If this crucial step is skipped, your system will quickly stop running, and you’ll be forced to install a new unit anyway. If you are dead set on exploring retrofitting, then consult with an HVAC professional to determine your best replacement refrigerant.
Your manufacturer will possibly not pay for the parts to make this swap because retrofitting your AC system will likely void the warranty. It’s typically just a temporary fix, but buying a new upgraded AC system will probably benefit most homeowners in dependability, satisfaction, and long-term comfort.
It’s smart to discuss pricing choices with your HVAC provider if you’re worried about cost. At Service Experts Heating & Air Conditioning, we have financing available that makes a replacement affordable, and we keep track of any manufacturer and utility rebates that would make it easier to handle a surprising replacement. To avoid emergencies on a hot day, lots of our customers choose to do a pre-emptive replacement, and replace an old system before it doesn’t work. If you’re of a similar mind, 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 dilemma may not apply to you, because it’s possible 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 reviewing 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, especially if it’s older than a decade, you have some options:
- Shop for an upgraded, more environmentally-friendly system that uses R410a.
- Contact an expert to replace the parts in your current unit to help make it compatible with an approved air conditioner refrigerant. This is not recommended.
- Stick with using recycled R22 and burn cash like it’s the ozone layer.
To be clear, the EPA regulates the production and use of this refrigerant, but not your system. You are not required by the law to replace your air conditioner. At some point, your AC will quit running and it will need to be replaced, and only R410a units will be available for sale.
The most straightforward option is to buy a new, upgraded air conditioner, specifically 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 even easier. New AC equipment can be more efficient and offer you superior comfort, helping to decrease your energy costs.
You could also select the status quo and continue using recycled R22 air conditioning refrigerant for the foreseeable future. While this sounds like a great alternative, the price 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 increase as demand continues to rise on a substance that is no longer produced or widely obtainable.
If you aren’t confident what type of AC refrigerant your air conditioning system uses, we can help. Reach out to Service Experts Heating & Air Conditioning today and we can provide an inspection to determine if you are currently using R22 and, if so, which option works best for you.
The good news
While making the switch to an approved AC refrigerant may be frustrating, it’s helping to save the ozone layer. These regulations will help defend 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 big part of this by replacing an old R22 unit with a newer, ozone friendly unit.
