You’ve heard it from three different contractors this year. Your R-410A rooftop unit is “about to be illegal.” Your R-22 system “can’t be serviced anymore.” Someone even mentioned a 2025 deadline that sounds like a countdown to disaster.
Picture a property manager in Aurora who got a bid for a full retrofit last month. The bid came from a rumor about federal refrigerant rules, nothing more. The Thrivaire technician who inspected the unit found a failed capacitor and a dirty condenser coil. No retrofit needed, no rule violation. Just a repair.
That kind of confusion is exactly what this guide, Blog: Refrigerant Regulation Myths – “Do I Need a Retrofit?” (July), is meant to clear up. We separate the real rules from contractor scare tactics, so you can make a repair-versus-replace call based on facts, not fear.
Quick answer: No. Servicing an existing R-410A or R-22 system is legal in Colorado. Federal HFC phasedown rules restrict new manufacturing and refrigerant production. They do not restrict repairs to units already installed. A retrofit only makes sense if the compressor fails, refrigerant becomes hard to find, or the unit is nearing 25 to 30 years old.

Is Your R-410A or R-22 System Actually Illegal to Service?
No. It is not illegal to service existing refrigeration and cooling equipment in Colorado, or anywhere else in the country. The rules target new manufacturing and refrigerant production. They don’t touch repairs to units already installed.
The AIM Act and EPA’s HFC phasedown, explained simply
The AIM Act is the American Innovation and Manufacturing Act of 2020. It directs the EPA to manage a phasedown of hydrofluorocarbons (HFCs), the refrigerants used in most R-410A systems. HFCs carry a high global warming potential (GWP), a measure of a refrigerant’s environmental impact compared with carbon dioxide.
The phasedown is a production and consumption schedule. It is not a service ban. Federal rules set the reduction starting at 90% of a baseline in 2022. That drops to 15% by 2036. The schedule governs how much new HFC refrigerant manufacturers can produce. It has nothing to do with whether your rooftop unit can be repaired today.
What the phasedown really targets: production, not your rooftop unit
Here’s the distinction most contractors skip. The EPA’s Technology Transitions program sets which refrigerant new units must use going forward. It does not require facility owners to retrofit or replace units that are already running.
Say you manage a strip mall with a 2018 R-410A rooftop unit. A contractor tells you it is “no longer legal” because of the 2025 refrigerant transition. That’s a myth. R-410A stays legal for use in existing cooling and heat pump systems, per Trane. What changed is the rule for newly built units, which must use a lower-GWP refrigerant starting January 1, 2025.
Pro tip: Check the nameplate manufacture date on your unit before you agree to anything. If it was built before January 1, 2025, the rule for new units doesn’t apply to it.
R-22 vs. R-410A: two different timelines, two different rules
R-22 and R-410A sit on separate regulatory tracks. Mixing them up fuels a lot of the confusion.
- ✓ R-22 (HCFC-22): production and import of new R-22 stopped in the U.S. on January 1, 2020, per the EPA.
- ✓ R-22 systems: still legal to run and service using reclaimed or recycled supply.
- ✓ R-410A: still legal in existing units. Only new units must switch to lower-GWP refrigerants after 2025.
- ✓ Neither rule forces anyone to remove a working system.
When Does a Retrofit Actually Make Sense (and When It Doesn’t)?
A retrofit is rarely a legal requirement. It’s a technical call based on age, compressor condition, and refrigerant availability, not a legal deadline. The same logic applies to commercial refrigeration equipment, not just rooftop cooling units.
What a technician checks on-site before recommending anything
A facility manager called last spring, convinced a full retrofit was needed after hearing about federal refrigerant rules on a podcast. A technician found a weak run capacitor causing short-cycling instead. A modest repair fixed it. No retrofit, no new hardware, no drama.
Before anyone recommends a retrofit, a qualified technician should check:
- ✓ Unit age and total run hours
- ✓ Compressor health and refrigerant circuit integrity
- ✓ Local availability of replacement refrigerant for that system type
Why A2L refrigerants can’t just be converted into old units
A2L refrigerants are mildly flammable, lower-GWP options showing up in new units across the industry. They offer a lower global warming potential than R-410A, but they’re built for units engineered to handle them, with specific parts and safety controls.
Older R-410A units cannot simply be retrofitted to run on A2L refrigerants. The seals, parts, and safety features were never designed for a mildly flammable refrigerant. If a contractor offers that kind of retrofit on aging units, ask for the manufacturer documentation that backs it up.
Pro tip: Lean toward replacement once a unit passes the 25 to 30 year mark, or after a second major compressor failure on the same system. Below that threshold, repair is usually the safer bet financially.
Repair vs. retrofit vs. replace: the real decision tree
Step 1: Confirm the unit is actually the source of the problem, not a control board, thermostat, or airflow issue.
Step 2: If it is a refrigerant circuit failure, weigh repair cost against remaining useful life.
Step 3: Only consider a retrofit or full replacement if repair cost nears the price of a new unit, or the refrigerant type is no longer reasonably available.
What Do Colorado Facility Managers Actually Need to Stay Legal?
Staying compliant mostly comes down to certified technicians, accurate records, and prompt leak repairs. It rarely means mandatory retrofits.
Technician certification and refrigerant reclaim records
Under Section 608 of the Clean Air Act, any refrigerant purchase in a container larger than 2 pounds requires the buyer to hold current technician certification, per Facility Compliance Hub. That rule applies whether you’re servicing R-22, R-410A, or a newer refrigerant blend.
Picture a facility manager who keeps every refrigerant invoice and certification card in one binder. When an inspector calls, the paperwork is ready in minutes. Reputable Colorado HVAC contractors keep that certification current and ready to show on request.
Facilities also need to track reclaimed refrigerant supply. That’s the record of refrigerant recovered, recycled, and reused instead of vented. The federal program combines production reduction and reclamation to support legal resupply. Reclaimed supply is legal, and it’s often the most practical way to keep an older R-22 system running.
Leak detection and repair timelines
Larger commercial refrigeration and cooling installations above certain size thresholds may also need automatic leak detection under updated federal rules. Units holding 50 pounds or more of ozone-depleting refrigerant, or 15 pounds or more of HFC refrigerant, need specific documentation starting in 2026, per Facility Compliance Hub.
Automatic leak detection matters because undetected leaks waste refrigerant and energy. They also create the kind of gap that draws attention during an inspection.
What enforcement risk actually looks like
Real enforcement risk isn’t a mysterious retrofit mandate. It’s incomplete paperwork. Current guidelines allow penalties up to $44,539 per day, per violation, per Facility Compliance Hub. That figure applies to documented gaps in servicing and recordkeeping, not to owning an older unit.
Pro tip: Keep every refrigerant purchase invoice, leak test record, and technician certification on file in one place. That paperwork, not a retrofit, is what protects you in an audit.
What Does Guessing Wrong on Retrofit vs. Repair Actually Cost?
Misreading the retrofit question can cost thousands of dollars. The numbers usually favor repair longer than most owners expect.
Repair vs. replace: a real-world cost scenario
Here’s how the math often plays out on a mid-life rooftop unit.
| Scenario | 15-year-old system |
| Compressor repair | Ranges from $6,000-$10,000 |
| Full replacement | Ranges from $25,000+ above |
| Remaining useful life after repair | Several more years, condition dependent |
These figures are illustrative planning estimates, not a quote for any specific unit.
Refrigerant availability and reclaimed-supply pricing trends
Reclaimed refrigerant is recovered from decommissioned units and cleaned to original specifications. It remains a legal, often cost-effective way to service older units, in HVAC and refrigeration alike. Used HCFC-22 cleaned to new-refrigerant specifications stays available even though new production ended. Supply has tightened over time. That’s one legitimate reason R-22 service costs have crept up.
The pattern behind “panic retrofit” calls
A common pattern shows up across service calls in the industry. A facility manager hears about federal refrigerant rules, assumes the system is suddenly noncompliant, and requests a retrofit. Once a technician inspects the unit, most of these calls resolve as a standard repair.
Pro tip: Before signing off on any retrofit, ask for a written side-by-side comparison of repair cost versus full replacement cost. If a contractor can’t produce one, get a second opinion.
Navigating refrigerant rules comes down to one thing: telling a sales tactic apart from a real technical requirement. Focus on your system’s actual condition. Keep solid records. That combination avoids unnecessary retrofits and keeps spending down. If you’re facing pressure to replace a system that still runs fine, call Thrivaire for a second opinion based on diagnostics, not regulatory myths.
A Quick Note on Rules
Refrigerant regulations are federal, driven by the national HFC phasedown. Permitting and enforcement can also involve state and local mechanical codes. This guide summarizes the general federal framework as of publication. It is not legal advice. Always confirm current requirements for your specific unit and jurisdiction with a licensed technician or the appropriate regulator.

Decision FAQs
Do I need to retrofit my R-410A rooftop unit before 2025? No. The January 1, 2025 date applies to newly manufactured units, not ones already installed and running.
Is it still legal to repair an R-22 system in Colorado? Yes. Servicing existing R-22 equipment remains legal using reclaimed refrigerant, even though new production ended January 1, 2020.
How old does a unit need to be before replacement makes more sense than repair? Replacement generally makes more sense once a unit hits 25 to 30 years old, or after a second major compressor failure.
Can a contractor legally force me into a retrofit? No. Nothing in the AIM Act or EPA phasedown rules requires replacing a legal, repairable existing system.
Technical/Process FAQs
R-410A vs. R-32 vs. A2L: what’s the difference? R-410A is a legacy HFC still legal in existing air conditioning and refrigeration systems. A2L refrigerants, including some R-32 blends, are mildly flammable, lower-GWP options required in most new units made after January 1, 2025.
What certification does a technician need to purchase refrigerant? Anyone buying refrigerant in a container larger than 2 pounds needs Section 608 technician certification.
How fast must a detected refrigerant leak be repaired? Units above certain refrigerant thresholds face specific documentation and repair requirements, with new rules for those holding 50 pounds or more of ODS refrigerant taking effect in 2026.
What is reclaimed refrigerant, and is it legal to use in my system? Reclaimed refrigerant is recovered refrigerant cleaned to original specifications. It is legal supply for servicing existing R-22 and R-410A units.
