If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably learn. R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it’s certainly incredibly vital. 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 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
Moving ahead a few decades 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, began 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 commenced. By early 2010 the production and import of R22 became prohibited. However, servicing current, existing equipment is still allowed as long as 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 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 this sounds like a case study on supply and demand, then you are on the right track. As you likely understand, older air conditioners could more frequently experience leaks and need repairs. Any units 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 risen due to scarcity.
Remember that in order to obtain R22, you must be an EPA-certified technician. So, the average homeowner can’t purchase a cylinder themselves. Also, there are some strict regulations now on how refrigerant must be reclaimed and recycled, which raises the price. This cost 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 systems.
So, how does this impact you?
The cost of R22 is radically increasing because of the dwindling supply, and new refrigerant will no longer be available for use at all after 2020, excluding recycled quantities.
If you’re thinking, “Holy cow, this is starting to sound expensive,” you’re right, it is. This is why when our experts come out to assess your unit we make sure to see what refrigerant your unit uses, and in the majority of the cases, we’ll advocate for 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 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 air conditioner may not have R22. You can find the type of refrigerant your system runs on by checking the appliance’s nameplate. This nameplate is typically found on the outdoor condenser of your central air conditioning system. If you can't find it, you can check your user’s manual. Alternatively, 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 quickly 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. For the rest of this article, we’ll use the name R410a (although Puron is a familiar 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.
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 route. Usually a homeowner who is concerned about the cost of replacing their system seeks out an alternative, and this appears to be an easy solution. It often costs the homeowner more money, and almost always voids the manufacturer warranty. The truth about “drop-ins” is that there is no “drop-in” solution where you merely swap out the refrigerant. The phrase “drop-in” is suggesting retrofitting a unit, which when done properly can cost the homeowner as much, or more, money than purchasing 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 be compatible with the new refrigerant. If this vital step is skipped, your system will quickly stop running, and you’ll need to get a new unit anyway. If you are insistent on exploring drop-ins, then consult with an HVAC company to determine your best replacement refrigerant.
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 purchasing 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 concerned 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 swallow an unexpected replacement. To reduce the chances of an emergency on a hot day, a lot of of our customers decide to do a pre-emptive replacement, and replace an old system before it quits working. 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 probably 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 find this and the refrigerant type by reading the nameplate on your condenser (the condenser is the outside unit).
What do I do if my air conditioner uses R22?
To summarize, if your HVAC equipment was produced prior to January 2010, particularly if it’s older than a decade, you have these 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 advised.
- 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 AC. You aren’t required by law to replace your air conditioner. Ultimately, your AC will not work and it will need to be replaced, and only R410a units will be available to buy.
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 several 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 give you superior comfort, helping to lower your energy costs.
You could also choose the status quo and continue using recycled R22 air conditioning refrigerant for the foreseeable future. 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 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, let us help. Call Service Experts Heating & Air Conditioning today and we can provide an inspection to confirm 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 exaggerated to say that you, as a homeowner, are a large part of this by replacing an old R22 unit with a newer, ozone friendly unit.
