Does my system use R-22?
The refrigerant type is usually printed on the nameplate. For central AC, EPA says that's usually on the outdoor unit. If there's no nameplate, check the owner's manual, or look up the manufacturer and model number (EPA). R-22 may also be listed as HCFC-22.
If you can't read the label, a technician can tell you during a service visit.
What the phase-out actually means
R-22 depletes the ozone layer, so the U.S. has been phasing it out under the Clean Air Act and the Montreal Protocol. According to EPA (homeowner FAQ):
- No new R-22 since 2020. Production and import ended January 1, 2020.
- You can keep using your system. EPA doesn't require you to stop using or replace R-22 equipment.
- Service continues. Recovered and reclaimed R-22, plus R-22 made before 2020, is expected to meet the needs of existing systems "well beyond the phaseout date."
- You can't buy a new central AC that uses R-22.
Can I still get it recharged?
Yes, but a recharge alone is the wrong fix. AC refrigerant doesn't get "used up." If the level is low, there's a leak. EPA says homeowners should ask technicians to "locate and repair leaks instead of 'topping off' leaking systems." That protects the environment and helps minimize future service calls and repair costs.
It's also illegal to knowingly vent refrigerant while servicing or disposing of AC equipment. Service should be done by an EPA Section 608-certified technician (EPA). OBC Air & Heat technicians are EPA Section 608 certified.
Why R-22 repairs get harder to justify
With no new supply, R-22 service depends on a limited pool of reclaimed and older refrigerant. Systems old enough to use R-22 are also older in every other way: coils, compressors, motors and controls. An R-22 system is also rated under the old SEER test, and today's minimum for new split-system ACs in Florida is 14.3 SEER2 under 45,000 Btu/h (AHRI).
So a major R-22 repair, especially a big leak, coil or compressor, is often the moment to compare repair with replacement. EPA's own advice: if your equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional. See Repair or Replace?.
What about switching refrigerants (retrofits)?
EPA says some R-22 systems can be converted to another refrigerant. These "retrofits" are allowed only if the substitute is listed as acceptable under EPA's SNAP program for that use. Before the switch, a Section 608-certified technician must recover the R-22.
But EPA is clear: "There are no 'drop in' replacements for HCFC-22." Alternatives won't work well without changes to system components. EPA also notes that equipment generally runs most efficiently on the refrigerant it was designed for (EPA).
Be cautious of any offer to "just fill it with something else."
What refrigerant will a new system use?
Most systems installed in recent years use R-410A. Since January 1, 2025, EPA rules have limited the manufacture and import of new residential and light commercial AC systems that use refrigerants with a global warming potential above 700. R-410A is above that limit (EPA). A May 2026 EPA rule allows systems made or imported before January 1, 2025 to keep being installed until supply runs out (EPA fact sheet).
Newer systems use lower-GWP refrigerants. EPA lists R-454B (GWP 470) and HFC-32 / R-32 (GWP 675) as acceptable, with use conditions, for new residential and light commercial AC and heat pumps. Both are classed A2L, meaning mildly flammable, and installation follows the safety conditions in EPA's rules (EPA SNAP).
What this means for you: if you replace an R-22 system, you replace the matched indoor and outdoor equipment, not just one part, and the existing refrigerant lines get checked too. We service R-410A systems, and the new systems we install use R-454B or R-32, depending on the equipment.
Light commercial owners
The same rules apply to the small rooftop and split systems on storefronts, offices, churches and restaurants. If an older R-22 unit serves your business, plan the replacement before a peak-season failure. See light commercial.
Before you call: safe checks
If an older system isn't cooling, check the filter, the thermostat and the breaker (reset once only). Look for ice on the refrigerant lines; if you see it, turn the system off and call. Don't add refrigerant yourself. Ask Mikey for more safe checks.
The next step
We check the nameplate, look for leaks and give you the repair and replacement options in writing. If you replace, ask how the new system's size was chosen. See Sizing an AC for Florida Humidity and Heat Pumps in Brevard. After that, regular maintenance helps it last.

Frequently asked questions
Can I still get my R-22 air conditioner recharged?
Yes. Recovered, reclaimed and pre-2020 R-22 is still used for service. But low refrigerant means a leak. EPA recommends finding and repairing leaks instead of topping off.
Do I have to replace my R-22 system?
No. EPA doesn't require you to replace working R-22 equipment. If it's more than 10 years old or not keeping you comfortable, EPA recommends a professional evaluation.
Is there a drop-in replacement for R-22?
No. EPA says there are no drop-in replacements. Retrofits to SNAP-acceptable alternatives require component changes and recovery of the R-22 by a certified technician.
How do I know if my AC uses R-22?
Check the nameplate, usually on the outdoor unit. It may say R-22 or HCFC-22. Otherwise check the manual or the manufacturer's website.
What refrigerant do new AC systems use?
Many recent systems use R-410A, and newer systems use lower-GWP refrigerants such as R-454B or R-32.
