California’s refrigerant phase-out rules combine three enforcement tracks run by the California Air Resources Board (CARB): bans on high-Global Warming Potential (GWP) refrigerants in newly installed equipment, a phased ban on bulk sales of newly produced HFCs, and ongoing leak-management duties for any facility with a system holding more than 50 pounds of high-GWP refrigerant. The framework is driven by Senate Bill 1383’s target of cutting hydrofluorocarbon emissions 40 percent below 2013 levels by 2030.1California Air Resources Board. California Significant New Alternatives Policy (SNAP) Several deadlines land in 2026, including a new GWP cap on variable refrigerant flow systems and a company-wide emissions benchmark for large retail food chains.
How GWP Thresholds Drive the Rules
GWP measures how much heat a gas traps compared to carbon dioxide. A refrigerant with a GWP of 1,500 is 1,500 times more potent than CO₂ pound for pound. CARB uses two classifications that recur throughout the regulations: “low GWP” means below 150, and “ultra-low GWP” means below 10.2California Air Resources Board. FRIP Funding Guidelines C&I Refrigeration Ultra-low options include CO₂ (GWP of 1) and certain hydrofluoroolefins. Older refrigerants like R-404A sit above 3,900, which is why they are the first to be phased out.
GWP Limits for New Equipment
Equipment prohibitions vary by sector, system size, and installation date.
Commercial Refrigeration
New refrigeration equipment with a charge above 50 pounds at a commercial facility must use a refrigerant with a GWP below 150. That cap took effect January 1, 2022.1California Air Resources Board. California Significant New Alternatives Policy (SNAP) It covers supermarkets, convenience stores, and similar retail operations. Most new installations use CO₂ transcritical systems or low-GWP HFO blends.
Cold storage warehouses follow a two-track rule. New equipment installed in a pre-2022 cold storage facility has been limited to a GWP of 1,430 or below since January 1, 2023. Cold storage facilities built after 2022 must meet the stricter 150 GWP cap. Ice rinks, both new and existing, have been subject to GWP limits since January 1, 2024.
Air Conditioning, Heat Pumps, and VRF Systems
New residential and commercial air conditioning equipment, including chillers and heat pumps, must use refrigerants with a GWP below 750. That limit took effect January 1, 2025, for most equipment categories. Variable Refrigerant Flow (VRF) systems were given an extra year: the 750 GWP cap applies to new VRF installations starting January 1, 2026.3California Air Resources Board. Updated Informative Digest
The federal EPA Technology Transitions Rule allowed a one-year sell-through for certain residential and light commercial AC equipment manufactured before January 1, 2025, permitting installation through January 1, 2026 even above the 750 GWP threshold.4California Public Utilities Commission. CPUC Rulemaking 19-01-011 – Prohibition on High GWP Refrigerants in Appliances Incentivized by Building Decarbonization Programs That window has closed. Any new installation must now comply with the GWP cap regardless of manufacturing date.
Bulk HFC Sales Ban Under SB 1206
Senate Bill 1206 targets the supply side, banning the sale of newly produced bulk HFCs on a phased schedule tied to GWP:5California Legislative Information. Bill Text – SB-1206 Hydrofluorocarbon Gases: Sale or Distribution
- January 1, 2025: no newly produced bulk HFCs above 2,200 GWP (covers R-404A and R-507A).
- January 1, 2030: ban extends to HFCs above 1,500 GWP (covers R-410A, the dominant residential AC refrigerant).
- January 1, 2033: ban extends to HFCs above 750 GWP (covers R-134a and mid-range blends like R-448A and R-449A).
Reclaimed HFCs are exempt, so you can still buy reclaimed refrigerant to service existing systems running on a banned product.5California Legislative Information. Bill Text – SB-1206 Hydrofluorocarbon Gases: Sale or Distribution As the 2030 and 2033 deadlines approach, reclaimed supply will tighten and prices will rise. If your equipment runs on R-410A, plan around the 2030 date.
Leak Inspection and Repair Under the Refrigerant Management Program
The Refrigerant Management Program (RMP) governs ongoing maintenance for any facility with a refrigeration system holding more than 50 pounds of high-GWP refrigerant.6California Air Resources Board. Refrigerant Management Program Its core duties are routine leak inspections, prompt repairs, and detailed service records.
How Often You Must Inspect
Inspection frequency scales with refrigerant charge:7California Air Resources Board. Leak Inspection – Save Money Through Early Detection
- 50 to 199 pounds: annual inspections.
- 200 pounds or more: quarterly inspections, unless an approved automatic leak detection system is in place.
- 2,000 pounds or more with components inside a building: continuous automatic leak detection monitoring, calibrated annually.
A 10 percent annual leak rate is the threshold separating a well-maintained system from one that triggers escalating compliance duties.8California Air Resources Board. Final Regulation Order
Repair Deadlines
Once a leak is detected, you have 14 days to complete the repair using an EPA-certified technician, with initial and follow-up verification tests confirming the fix worked.9California Air Resources Board. Refrigerant Management: Are You Leaking Money? Three situations extend that window:
- 45 days when a certified technician is unavailable, necessary parts are on backorder (with vendor documentation), or the repair requires an industrial process shutdown.
- 120 days for facilities subject to mandatory greenhouse gas reporting, where the system is industrial process refrigeration and repair requires a process shutdown.
- Indefinitely if the refrigerant is evacuated and the system is mothballed.
If repair is not possible within the applicable deadline, the owner must prepare a retrofit or retirement plan that schedules all work for completion within six months of the date the leak was first detected.10Legal Information Institute. California Code of Regulations Title 17, 95387 – Requirements to Prepare Retrofit or Retirement Plan Six months disappears quickly once equipment lead times and contractor availability enter the picture.
Company-Wide Targets for Retail Food Operators
Large grocery chains and supermarket operators face aggregate emissions targets across all their California locations, separate from the equipment-by-equipment rules.
Companies owning or operating 20 or more retail food facilities in California, plus national supermarket chains operating in the state, must hit one of two benchmarks by December 31, 2026: a company-wide weighted-average GWP below 2,500, or a 25 percent reduction in greenhouse gas emission potential below 2019 levels.11California Air Resources Board. Retail Food Facility
By January 1, 2030, every retail food company in California — regardless of size — must reach a company-wide weighted-average GWP below 1,400 or a 55 percent reduction in greenhouse gas emission potential below 2019 levels.11California Air Resources Board. Retail Food Facility Operators with fewer than 20 facilities see 2030 as their first mandatory benchmark. Meeting these targets usually means converting existing cases and walk-ins to CO₂ or low-GWP HFO systems.
Technician Certification
Anyone who maintains, services, repairs, or disposes of refrigerant-containing equipment must hold EPA Section 608 certification.12US EPA. Section 608 Technician Certification Requirements California’s RMP reinforces this by requiring certified technicians for all leak repairs. Technicians working on the stationary commercial and industrial systems covered by California’s rules need either Type II (high-pressure and very-high-pressure appliances) or Universal certification. The credential does not expire. Verify certification status for every contractor and in-house technician who touches a system, because using an uncertified technician is a violation under both federal and state rules.
Annual Reporting and Recordkeeping
Every facility with a refrigeration system holding 200 pounds or more of high-GWP refrigerant in its largest system must file an annual report to CARB through the Refrigerant Registration and Reporting (R3) tool by March 1, covering the prior calendar year.13California Air Resources Board. Refrigerant Management Program (RMP) Frequently Asked Questions Facilities between 50 and 199 pounds still must inspect and maintain records, though they do not file annual reports.
The report is detailed. It includes service and leak repair records with dates, cause of each leak, descriptions of repairs, verification test results, and the name and EPA certification number of the technician who did the work. You also report total weight of each refrigerant type purchased, charged into systems, recovered, held in inventory, and shipped for reclamation or destruction during the year. Equipment-specific data covers each system’s full charge, refrigerant type, manufacturer and model, temperature classification, and physical location on a floor plan.14California Air Resources Board. RMP: Registering and Reporting
All records and supporting documentation must be retained for at least five years from the date the report is submitted.15Legal Information Institute. California Code of Regulations Title 17, 93405 – Document Retention and Record That includes refrigerant purchase invoices, vendor backorder documentation supporting any extended repair timeline, and automatic leak detection calibration records. Facilities often trip enforcement actions on documentation rather than substance: if you cannot produce the records to prove compliance, CARB treats it as a violation.
Penalties for Noncompliance
CARB enforces the RMP and SNAP regulations under California Health and Safety Code section 38580. Each day a violation continues is a separate offense.16Legal Information Institute. California Code of Regulations Title 17, 95368 – Enforcement A missed repair deadline or a late annual report can generate rapidly stacking liability. CARB can also seek injunctive relief under Health and Safety Code section 41513, which allows a court to order you to stop operating noncompliant equipment.
Federally, Clean Air Act violations, including AIM Act provisions, carry civil penalties of up to $472,901 per day as of the most recent inflation adjustment.17eCFR. Statutory Civil Monetary Penalties, as Adjusted for Inflation, and Tables That ceiling is typically reserved for major violations, but even a single enforcement action can be ruinous for a mid-size operation.
How the Federal AIM Act Overlaps
The federal American Innovation and Manufacturing (AIM) Act, enforced by the EPA, runs a separate nationwide HFC phasedown. From 2024 through 2028, the federal HFC consumption cap sits at 60 percent of baseline, stepping down to 15 percent by 2036. The AIM Act does not preempt California’s stricter rules; both apply simultaneously.18US EPA. Frequent Questions on the Phasedown of Hydrofluorocarbons The federal Technology Transitions Rule also sets its own GWP limits that took effect January 1, 2025 and January 1, 2026 across various equipment sectors.19US EPA. Technology Transitions HFC Restrictions by Sector For multistate operators, the stricter of the federal or California limit controls each equipment type.
Federal Tax Deduction for Low-GWP Upgrades
The federal Section 179D deduction offsets some of the cost of installing energy-efficient HVAC systems, which can include low-GWP cooling equipment. For property placed in service in 2025, the base deduction runs from $0.58 to $1.16 per square foot for buildings achieving at least 25 percent energy savings. Projects meeting prevailing wage and apprenticeship requirements qualify for an enhanced deduction of $2.90 to $5.81 per square foot.20Internal Revenue Service. Energy Efficient Commercial Buildings Deduction The amounts are adjusted annually for inflation. The deduction applies to the building’s qualifying improvements as a whole, so pairing a low-GWP system conversion with a broader energy retrofit maximizes the benefit.
