The A2L Transition Is Here — What It Means for Your Mortuary Cooler
The refrigeration industry is in the middle of its most significant regulatory shift in a generation. Congress passed the American Innovation and Manufacturing (AIM) Act in 2020, authorizing the EPA to phase down the production and consumption of high Global Warming Potential (GWP) hydrofluorocarbon (HFC) refrigerants — the same R-404A and R-448A refrigerants that have powered commercial walk-in coolers, including mortuary coolers, for decades.
The replacement refrigerants are classified as A2L — a category defined by the ISO 817 standard as low-toxicity, mildly flammable, and dramatically lower GWP. For walk-in mortuary coolers, the primary A2L replacement refrigerant is R-454A, which delivers comparable cooling performance to R-404A while reducing GWP by approximately 76%. American Mortuary Coolers walk-in units are designed and built to be compatible with A2L refrigeration systems — putting your facility ahead of the compliance curve, not scrambling to catch up.
Legacy HFCs Being Phased Out vs. A2L Replacements
DOE AWEF — Why Energy Efficiency Ratings Now Matter for Mortuary Coolers
The Annual Walk-In Energy Factor (AWEF) is the Department of Energy's mandatory efficiency metric for commercial walk-in cooler refrigeration systems. It measures how effectively a refrigeration system converts electrical energy into cooling capacity over a full year of operation — specifically the ratio of total heat removed (BTUs) to total electrical energy consumed (watt-hours).
A2L Compliance Timeline — Every Mortuary Facility Needs to Know
A2L Compatible Walk-In Mortuary Coolers — Starting at $3,600
Every American Mortuary Coolers walk-in box is A2L refrigerant compatible — built to accept DOE AWEF-rated A2L condensing units and evaporator coils when specified by your licensed HVAC-R contractor. The box: all-metal cam-lock panel construction, 4" polyurethane R-28.4 insulation, NSF-certified stainless interior, OSHA interior safety release. The refrigeration system: specified and installed by your contractor using A2L-compliant components per SNAP Rule 26 requirements.

Official A2L & DOE Compliance Resources
American Mortuary Coolers supports your compliance planning. The resources below are official and authoritative — the EPA, DOE, and Heatcraft (a leading refrigeration component manufacturer) all publish detailed A2L compliance guidance you can reference when working with your HVAC-R contractor.
Why A2L Refrigerants Are a Game-Changer for Mortuary Facilities
Environmental Stewardship — Quantified
Legacy refrigerant R-404A carries a GWP of 3,922 — meaning each pound released into the atmosphere traps 3,922 times more heat than CO₂ over a 100-year period. R-454A, the primary A2L replacement for walk-in coolers, carries a GWP of 239. That's an approximately 94% reduction in climate impact per pound of refrigerant. For a mortuary facility that replaces a 10-15 lb refrigerant charge, the environmental difference is real and measurable — not a marketing claim.
Operational Cost Reduction — The AWEF Connection
Higher AWEF ratings mean the same 34°F–39°F mortuary preservation temperature is maintained with less electricity. With energy costs rising and commercial refrigeration running 24/7/365, a meaningful AWEF improvement compounds into significant operating cost savings over the 15-year panel life of a mortuary walk-in cooler. A2L-compatible refrigeration systems from manufacturers like Heatcraft are engineered to deliver AWEF ratings at or above their legacy HFC counterparts.
Future-Proof Compliance — No Retrofit Scramble
Mortuary facilities that install A2L-compatible walk-in systems in 2025–2026 are positioned ahead of the compliance curve through 2036 and beyond. Facilities still running high-GWP HFC equipment will face an increasingly expensive service environment as legacy refrigerant production is phased down, supply shrinks, and prices rise. The cost of proactive compliance now is lower than reactive compliance under supply pressure later.
Funding & Incentives
Federal and state energy efficiency programs may offer rebates or incentives for commercial refrigeration upgrades to A2L or other low-GWP systems. Confirm available incentives with your state energy office and HVAC-R contractor before purchasing. A2L upgrades may also qualify for accelerated depreciation under Section 179 for institutional buyers. See our financing options for additional support.
