Air conditioning technology is always advancing, but some changes aren’t about making our equipment more efficient or more powerful. For decades now, there has been work done to reduce the environmental impact our air conditioners have. This is an effort going on all around the world, not just in Kansas or the United States. A major part of this push has been striving to eliminate chemicals that hurt the ozone layer.
A new regulatory step in that effort came into play in the United States on the first day of 2020. For some American homeowners, this meant a major change.
The Suspect Chemical: R22
R22 is a refrigerant that has been used for decades in residential and commercial air conditioners. First introduced in the 1950s, R22 is the trade name for chlorodifluoromethane. The chemical is also commonly known as Freon, which was the trademark chosen for it by its first manufacturer, the DuPont Corporation.
Even in the 1950s, the damage that refrigerants could do to the ozone layer was understood. In large enough quantities, the common refrigerants of the day depleted the ozone layer and reduced the level of protection it offered from the sun’s harmful UV radiation. R22 was originally considered to be a major step forward when it was introduced because it did far less damage than earlier refrigerants like CFC-11 and CFC-12.
“Less damage” is not the same as “no damage,” though, and in the 21st century, governments have taken steps to eliminate R22 entirely. When released into the atmosphere, R22 causes 1800 times more damage than carbon dioxide.
Regulatory steps against R22 have varied from nation to nation. In the United Kingdom and the European Union, the refrigerant has already been phased out completely. The United States has been on a similar path, but at a slower pace.
In the United States, the sale of new equipment designed for the use of R22 was banned in 2010. Manufacturers and maintenance companies were allowed to produce R22 and use it to recharge already-installed air conditioning systems. As long as the equipment remains in good working order and does not leak, the continued use of R22 had been allowed.
The United States took a large step toward phasing out R22 entirely on January 1, 2020. Since then, the manufacture and sale of new R22 has been discontinued. There is a possibility that some R22 systems can continue to operate using recycled refrigerant, but no one knows how long supplies will last.
Will This Phase-Out Affect My AC System?
If your air conditioning system is over a decade old (installed prior to 2010), it could be using R22 refrigerant. The odds of R22 use increase steadily as you consider older equipment, and if your air conditioner was installed before 2003, it almost certainly is using R22. 2003 was the first year restrictions on R22 equipment came into effect.
A lot of homeowners may be negatively impacted by the phaseout in 2020. Aging air conditioning units are likely to require significant maintenance work. That work can only get more difficult (and expensive!) if the system’s preferred refrigerant is suddenly almost impossible to find.
Checking Your AC for R22
Determining whether or not your home air conditioner uses R22 should be fairly easy. Check your outdoor AC unit, the condenser, for a nameplate. This nameplate should list the system’s refrigerant. R22 may also be listed as HCFC-22. You can also check your air conditioner’s user manual. It should list the type of refrigerant used. If you need help determining what type of refrigerant your AC system uses or need advice on how to proceed with an R22 air conditioner, please feel free to contact us at Standard Plumbing, Heating & Air Conditioning online or by calling (785) 776-5012 and we can help determine what your air conditioner requires.
Haven’t We Been Through This Before?
If you were already an adult in the late 1980s, you may remember going through a similar refrigerant phase-out that applied to the air conditioners in our cars. At that time, regulations targeted the R-12 refrigerant older car air conditioners used. The choice for vehicle owners was to either invest in upgrading their vehicle’s air conditioner or pay more and more for R-12 refrigerant.
What Will Be Used in Place of R22?
The replacement of choice for R22 is R410A. The most popular and widely known brand name for this refrigerant is Puron®, but identical refrigerants are available from multiple manufacturers under a range of different names. R410A was first brought to market in 1991 by a company in the Honeywell organization. Today R-410A is produced by a variety of different companies all over the world. This refrigerant is a great improvement over Freon, as it does not contribute in any way to the depletion of the ozone layer.
What Can I Do with an R22 AC Unit?
To be frank, your options are limited if your home’s air conditioner uses R22. Just like the car phase-out from the late 80s, you are facing additional costs no matter what you choose to do.
R22 Cannot Be Purchased By Homeowners
No amount of canny comparison shopping will net you a good deal on R22 refrigerant. R22 is not sold in local stores or through internet storefronts; the only people who can obtain it are licensed, EPA-certified air conditioning technicians. The cost of buying R22 from licensed technicians is going to rise as recycling the refrigerant in compliance with new regulations grows more expensive.
Other Refrigerants Cannot Be Substituted For R22
Air conditioning refrigerants are not interchangeable. It’s not possible to swap out some other chemical in place of the R22 your system is designed to use. Although it is feasible to have your system modified to work with a newer refrigerant, this sort of “drop-in” solution is very likely to cost more, in the end, than replacing your system with all-new equipment. Another significant problem is that these sorts of modifications will inevitably void the manufacturer’s warranty on your air conditioning equipment.
So, What Are Your Options?
As long as your air conditioning system is running smoothly, you don’t need to take any action. But once maintenance or AC repair work requires you to add refrigerant to your system, you have three basic options:
- You can attempt to keep your air conditioning system working with recycled R22 refrigerant. This is a very uncertain option and it is impossible to predict how quickly the cost of R22 will rise once new refrigerant is no longer being manufactured. As the available supply shrinks, costs will inevitably rise, and these costs will get higher and higher over time.
- You can talk to an HVAC technician about retrofitting your existing system to work with R410A. As noted above, this will almost certainly void your warranty. The cost of the parts required and the labor to do the job right may add up to be nearly as expensive as buying an all-new air conditioner.
- You can bite the bullet and have a new air conditioner installed. This will almost certainly be the most expensive option in the short term. But the silver lining with a new air conditioner is that it is the only option that permanently solves your R22 problem.
Take Action Sooner Rather Than Later
The best time to work with an HVAC contractor on major air conditioning work is at the end of winter or the beginning of spring. Demand for air conditioner work in the Manhattan area always spikes during the onset of warm Kansas summer weather; this is when the largest number of homeowners discover problems with their cooling systems. Our experienced ac technicians are inevitably in high demand when the Kansas heat first comes out in force, and we have to address our customers’ concerns on a first-come, first-served basis.
Don’t leave your air conditioning situation up in the air until the start of a hot Kansas summer! The new refrigerant regulations could set you up for a nasty surprise. Contact Standard Plumbing, Heating & Air Conditioning before the start of hot weather and let us help you map out a plan for keeping your home cool — not just this summer, but for many hot Manhattan summers to come.
