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 critical. Most air conditioning units older than 10 years have an AC refrigerant called R22 that’s commonly known as Freon*, and is referred to by the EPA as HCFC-22. In this guide, 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
Fast forward a few decades and the world realized that R22 refrigerant was aiding in the depletion of the Earth’s ozone layer. That’s not great. So, the U.S. EPA, in cooperation with other agencies and groups around the world, initiated 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 early 2010 the production and import of R22 was reduced. However, servicing current, existing equipment is still acceptable as long as 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. The production and import of R22 will be continually reduced by law until 2020, when all production and import will be forbidden. Only recycled R22 refrigerant will be obtainable 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 on the right track. As you can imagine, older air conditioners more often have 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 very limited supply. Prices have only gone up due to scarcity.
Don’t forget that in order to buy R22, you’ll need to be an EPA-certified technician. So, the average homeowner isn’t able to purchase a cylinder themselves. Also, there are some strict regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This fee is passed on to the homeowner as companies must cover the increased overhead related to R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing systems.
So, how does this impact you?
The cost of R22 is dramatically 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, “Wow, this is starting to sound expensive,” you’re right, it is. This is why when our technicians come out to inspect your unit we look to see what refrigerant your unit uses, and in the majority of the cases, we’ll advise an upgrade due to the increasing cost of taking care of 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 probably 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 looking at the appliance’s nameplate. This nameplate is typically found on the outdoor condenser of your central air conditioning system. If you can’t locate 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 right away if your unit uses R22.
Instead of Freon, use Puron
The industry has made the switch 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 recognized 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 provides a higher safety rating and an ozone depletion rating of zero, and it performed slightly better on energy-efficiency 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 of “drop-in” replacements for R22. We strongly against against this option. Usually a homeowner who is uneasy about the cost of replacing their unit seeks out an alternative, and this feels like an easy solution. It typically costs the homeowner more money, and almost always voids the manufacturer warranty. The fact about “drop-ins” is that there is no “drop-in” solution where you just swap out the refrigerant. The phrase “drop-in” is indicating retrofitting a unit, which when done correctly can cost the homeowner as much, or more, money than buying a new unit that uses R410a. In part, this is because different refrigerants operate at different pressure levels and need different parts to run, which results in the technician needing to replace the most expensive components of your system to be compatible with the new refrigerant. If this vital step is missed, your system will quickly stop running, and you’ll end up installing a new unit anyway.
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 normally 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 offers with your HVAC provider if you’re worried about cost. At Service Experts Heating & Air Conditioning, we offer financing that makes a replacement doable, and we monitor for any manufacturer and utility rebates that would make it easier to manage an unforeseen replacement. To avoid an emergency on a hot day, lots of our customers decide to do a pre-emptive replacement, and replace an old unit before it doesn’t work. If you’re considering that route as well, 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 likely that your system uses the new, approved replacement refrigerant, R410a. However, air conditioners installed after 2010 could still 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 recap, if your HVAC equipment was produced prior to January 2010, particularly if it’s older than a decade, you have these options:
- Purchase an upgraded, more environmentally-friendly system that uses R410a.
- Reach out to 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 what we recommend.
- 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 unit. You aren’t required by law to replace your air conditioner. Eventually, your AC will stop working and it will need to be replaced, and only R410a units will be available to purchase.
The best option is to buy a new, upgraded air conditioner, particularly if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has many financing options that help make the purchase affordable, and again, we look out for rebates from HVAC manufacturers and local utilities to help you out. New AC equipment is more efficient and present 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 time being. While this sounds like a nice alternative, the expense of servicing old R22 A/C systems is starting to go over several hundred dollars (easily a down payment on a new system). You may also see the prices climb as demand continues to rise on a substance that is no longer produced or widely obtainable.
If you aren’t aware of what type of AC refrigerant your air conditioning system uses, we can help. Call 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 move 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 implausible 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.
