What is the EPA refrigerant phaseout?
The EPA's HFC refrigerant phase-down tackles a critical environmental issue: the damaging impact of HFCs on the global climate.
HFCs, common refrigerants in HVAC and refrigeration systems, were hailed as a safer alternative to ozone-depleting CFCs. However, HFCs are potent greenhouse gases, trapping more heat than CO2 in the atmosphere and contributing to global warming.

To address this growing concern, the EPA, empowered by the 2020 AIM Act, launched a comprehensive HFC phaseout program for U.S. production and consumption. This multi-layered plan reduces HFC allowances and substantially cuts HFC use over the next decade.
The HFC phasedown schedule, as envisaged by the EPA, is as follows:
- 2022–2023: 10% reduction from baseline levels.
- 2024–2028: 40% reduction.
- 2029–2033: 70% reduction.
- 2034–2035: 80% reduction.
- 2036 and beyond: 85% reduction.
The EPA's ambitious goal is to achieve an 85% reduction in HFC consumption by 2036 is expected to pave the way for a smooth transition to more environmentally friendly alternatives. This initiative aims to encourage the development, adoption, and widespread use of refrigerants with a significantly lower global warming potential.
Key refrigerants affected
The EPA’s HFC phaseout program impacts several refrigerants, including:
- R-404A: Commonly used in commercial refrigeration for low-temperature applications
- R-134a: Used primarily on commercial chillers and older vehicle ACs
- R-410A: Used widely in commercial and residential ACs and chillers
- R-407C: Employed as a replacement for R-22 in existing ACs and refrigeration systems
- R-123 and R-22: These HCFC refrigerants are used in commercial cooling applications like HVAC and refrigerators

Detailed timeline of the EPA refrigerant phase-out schedule
The EPA’s HFC phaseout program is already underway and establishes production and consumption baselines following the formulas outlined in the AIM Act. These baselines serve as a reference point for allowable production and consumption levels, which will gradually decrease each year according to a predefined schedule within the AIM Act.
A table summarizing the consumption and production limits for the HFC phaseout is provided below. Additionally, the EPA issues allowances for HFC production and import on an annual basis, typically by October 1 of the preceding year.
Key EPA regulations that you should be aware of
- In new chiller production, HFC refrigerants like R-404A and R-410A are prohibited from 1st January 2024.

- The production of new equipment using R-22 ceased entirely in 2022, and the HCFC phaseout will be completed in 2030.
What are the alternatives to phased-out refrigerants?
With high-GWP HFCs like R-410A and R-404A facing steep restrictions, facilities and retail leaders must plan the shift to next-generation refrigerants. Choosing the right alternative is about more than compliance—it’s a critical operational and financial decision.
Here’s what you need to know about the most common EPA-approved alternatives:
- R-32:
- Widely used in new air conditioners and heat pumps
- Lower global warming potential (GWP) than R-410A
- High efficiency, but mildly flammable (A2L)—may require technician upskilling and updated safety protocols
- R-454B:
- Emerging as the preferred replacement for R-410A in commercial applications
- Even lower GWP than R-32
- Requires compatible equipment and A2L safety measures
- CO₂ (R-744):
- Natural refrigerant with ultra-low GWP
- Ideal for supermarkets, cold storage, and industrial uses
- Requires higher operating pressures and specialized components
- Ammonia (R-717):
- Common in large industrial refrigeration
- Zero GWP and excellent efficiency, but toxic and requires specialized handling
- Propane (R-290):
- Ultra-low GWP, increasingly used in commercial refrigeration and small equipment
- Flammable (A3), so often limited to smaller charge sizes
What to consider:
- Retrofit or replace? Not all systems can be retrofitted—consult OEM guidelines.
- Training: New refrigerants may require updated certifications and procedures.
Tech advantage: Using Connected refrigeration software can help track refrigerant inventory, leak rates, and compliance across multiple sites.
Future EPA deadlines to keep an eye on
Here are some future deadlines to watch out for in the HFC phaseout programs, especially for allowance reduction:
- 2024-2028: A significant allowance reduction of 60% from the baseline. Expect tighter restrictions on HFC availability and inflated prices.
- From 2029 onwards, the allowance reduction will reach 85% by 2034-35 and 90% by 2036. This will necessitate a substantial change in the business approach and the refrigerant used.
- Mandatory automatic leak detection systems (ALDS) for new and existing systems with a full charge of 1500+ lbs. of an HFC refrigerant or a substitute with a GWP > 53

- Starting 1st January 2028, the mandatory use of reclaimed refrigerant for servicing HFC systems
- Starting 1st January 2025, disposable cylinders must be sent to the reclaimer to remove the refrigerant heel.
Impact of the EPA refrigerant phaseout schedule on different industries
As mandated by the AIM Act, the EPA’s HFC phaseout program is being carried out in three ways:
- Phasing down production and consumption: Gradually reducing the production and consumption of HFCs to 15% of baseline levels by 2036.
- Maximizing reclamation and minimizing releases: Encouraging the reclamation of existing HFCs and minimizing their release from equipment to reduce environmental impact.
- Facilitating the transition to next-generation technologies: Implementing sector-based restrictions to promote the adoption of environmentally friendly alternatives with lower global warming potentials (GWPs).

However, the HFC phasedown presents a major challenge: identifying suitable alternatives that match the performance and compatibility of existing systems.
Additionally, the cost of new refrigerants and system upgrades, and training technicians to handle low-global warming potential (GWP) systems pose hurdles to a smooth phaseout of HFCs.
Industries most impacted by the phasedown include
- Refrigeration and air conditioning (HVAC/R): This industry will experience a full-blown shift. Manufacturers must develop and procure equipment compatible with low-GWP alternatives, while service technicians will require training to handle new refrigerants safely.
- Retailers: Supermarkets and retail stores must maintain proper temperature in freezers and display cases. They will now have to find cost-effective and energy-efficient replacements for their existing HFC refrigerators.
- Cold storage warehouses: Cold storage warehouses require consistent cooling for perishable goods.
- Industrial process facilities: Food processing, pharmaceuticals, and chemical manufacturing rely heavily on HFC-based refrigeration for temperature control. They will now have to find efficient replacements to ensure smooth operation.
- Data centers: These facilities rely on efficient cooling systems to maintain optimal temperatures for servers and other critical equipment. The phasedown necessitates the adoption of alternative refrigerants and potential upgrades to existing cooling infrastructures to ensure compliance and maintain operational efficiency.
- Transportation: The transportation sector, including refrigerated transport and vehicle air conditioning, accounts for approximately 8% of HFC use in the United States. The phasedown will require the development and integration of low-global warming potential (GWP) refrigerants in vehicles and transport refrigeration units.
