Understanding the EPA's Refrigerant Phaseout Schedule for 2024

As the EPA phases out certain refrigerants, understand the schedule, the implications for your business, and how to stay compliant.

The phaseout of hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act continues to reshape the HVAC and refrigeration industry.

For those maintaining or working with HFC-based equipment, this phaseout can feel like navigating uncharted waters.

While HFCs have been reliable refrigerants, they contribute to climate change. The AIM Act addresses this challenge by aiming to reduce HFC use.

However, significant global changes naturally raise questions about cost and benefits.

The Environmental Protection Agency (EPA) estimates positive net benefits of $16.4 billion annually by the final stage of the EPA refrigerant phaseout schedule. While initial apprehension is understandable, this article will help you navigate the impact of the EPA's regulations and how they aim to increase energy efficiency, reduce leakage rates, and optimize costs.

What is the EPA refrigerant phaseout?

The EPA's HFC refrigerant phaseout tackles a critical environmental issue: the damaging impact of HFCs on the 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 EPA's ambitious goal is to achieve an 85% reduction in HFC consumption by 2036, paving 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.

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.

Future 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, 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

The EPA’s HFC phaseout program is being carried out in three ways:

  1. Phasing down production and consumption
  2. Maximizing reclamation and minimizing releases from equipment
  3. Sector-based restrictions to facilitate the transition to next-generation technologies

The HFC phaseout 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 most by the phaseout include:

  • Refrigeration and air conditioning (HVAC/R): This industry will experience a full-blown shift. Manufacturers must  develop and procure equipment compatible with low GWPl alternatives, while service technicians will require training to safely handle new refrigerants.
  • 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 storages require consistent cooling for perishable goods. Finding large-scale, low-GWP refrigeration systems will be a top priority for these facilities.
  • 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.      

Opportunities for innovation and efficiency presented by HFC phaseout

The HFC phaseout acts as a catalyst for innovation in the HVAC/R industry by incentivizing the development and adoption of new low-GWP refrigerants. This shift also opens doors for the creation of new training programs and educational initiatives to equip technicians with the necessary skills to handle these alternatives.

While upfront costs associated with the transition may be a concern, the long-term benefits are significant. These include improved energy efficiency, reduced energy consumption leading to cost savings, and of course, a positive impact on the environment.
