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 certainly incredibly important. Most air conditioning units older than 10 years have an AC refrigerant called R22 that’s commonly identified as Freon*, and is noted 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 leading 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 considered one of the worst offenders.
Timeline and R22 phase out progress in 2018
In 2003, the phase out of R22 production and imports commenced. By the start of 2010 the production and import of R22 was reduced. However, servicing current, existing equipment is still allowed as long as there is an available supply of R22. To ensure the public’s compliance with the new law, all sales of R22 must be purchased by a certified technician. R22 production and import will be continually reduced by law until 2020, when all production and import will be eliminated. Only recycled R22 refrigerant will be accessible 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 are starting to think this is a great topic for an economics professor regarding supply and demand, then you are right. As you can imagine, older air conditioners may have more 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 very limited supply. Prices have only increased due to scarcity.
Don’t forget that in order to obtain R22, you must be an EPA-certified technician. So, the normal homeowner is unable 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 cost is passed on to the homeowner as companies have to cover the increased overhead connected to 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 radically increasing because of the declining 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 professionals come out to review your unit we check to see what refrigerant your unit uses, and in many 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 unit may not have R22. You can see the type of refrigerant your system runs on by reading the appliance’s nameplate. This nameplate is normally 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 immediately if your unit uses R22.
Instead of Freon, use Puron
The industry has moved from R22 to R410a, which you may know 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 valuable benefits to switching from an R22 air conditioning unit to one that uses R410a. It has a higher safety rating and an ozone depletion rating of zero, and it performed slightly better on energy-efficiency tests than R22.
You may have read about “drop-in” replacements for R22. We strongly advocate against this option. Usually a homeowner who is anxious about the cost of replacing their unit seeks out an alternative, and this sounds like an easy solution. It often costs the homeowner more money, and nearly 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 air conditioner, which when done correctly can cost the homeowner as much, or more, money than purchasing a new unit that uses R410a. In part, this is because different refrigerants function 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 be compatible with the new refrigerant. If this vital step is missed, your system will quickly stop working, and you’ll end up installing a new unit anyway.
Your manufacturer will possibly not pay for the parts to make this transition because retrofitting your AC system will likely void the warranty. It’s normally 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 options with your HVAC provider if you’re concerned about cost. At Service Experts Heating & Air Conditioning, we offer financing that makes a replacement affordable, and we monitor for any manufacturer and utility rebates that would make it easier to handle an unexpected replacement. To avoid emergencies on a hot day, a lot of of our customers choose to do a pre-emptive replacement, and replace an old system before it breaks down. 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, units installed after 2010 could still use R22, so it’s wise to check with an HVAC Expert. You can always look for 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, particularly if it’s older than a decade, you have some options:
- Buy an upgraded, more environmentally-friendly system that uses R410a.
- 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 what we recommend.
- Keep 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. 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 to buy.
The best option is to purchase 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 even easier. New AC equipment is more efficient and give you superior comfort, helping to lower your energy costs.
We do have one more option available in select locations. To provide our customers with high-quality equipment and service at competitive rates, we started the Advantage Program, which is a worry-free program that provides HVAC equipment with a full coverage repair and maintenance plan for a low monthly price.
You could also select the status quo and continue using recycled R22 air conditioning refrigerant for the near future. 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 grow as demand continues to rise on a substance that is no longer produced or widely accessable.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, let us 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, what you can do.
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 protect 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 big part of this by replacing an old R22 unit with a newer, ozone friendly unit.
