A2L & Low-GWP Refrigerants for Mortuary Coolers: The 2026 AIM Act Guide

Under the federal AIM Act, the HVAC-R industry — including mortuary refrigeration — is in the middle of a phase-down of high global-warming-potential (GWP) refrigerants. For funeral homes, hospital morgues, and pathology labs buying equipment in 2026, refrigerant type is no longer a background spec; it affects long-term compliance, service availability, and often energy efficiency.

What A2L means

A2L refrigerants are a class of lower-GWP, mildly flammable refrigerants that are replacing older high-GWP blends across commercial refrigeration. They're becoming the industry-standard direction for new equipment, not a niche upgrade. Buying A2L-ready now avoids a costly retrofit or early replacement as older refrigerants phase down further.

Compliance is only half the story

A2L refrigerants often carry favorable thermodynamic properties, meaning equipment designed around them can run efficiently — compliance and energy savings frequently move together rather than trading off against each other. That's a meaningful factor for a system that runs continuously, 24/7, for 15–20 years.

Where this applies across the line

Our A2L green-compliant mortuary coolers are built around this transition, with walk-in models from $3,600. Because refrigerant and efficiency specifications are model-specific, confirm the exact refrigerant and rating for the configuration you're considering before ordering — particularly for vault-style and multi-unit institutional installs where refrigeration is consolidated across many bays.

Planning your purchase around it

If you're comparing coolers for a 2026 purchase, refrigerant type belongs on the same checklist as capacity and footprint. Our energy-efficient mortuary equipment guide covers how refrigerant fits into the bigger efficiency picture alongside insulation, compressor type, and model selection.

Frequently Asked Questions

What is an A2L refrigerant?

A class of lower global-warming-potential, mildly flammable refrigerants replacing older high-GWP blends across HVAC-R equipment under the federal AIM Act phase-down.

Do I need A2L refrigerant to be compliant in 2026?

The industry is actively transitioning under the AIM Act. Buying A2L-ready equipment now helps avoid a retrofit or early replacement as older refrigerants continue to phase down.

Does A2L refrigerant improve energy efficiency?

Often, yes — many A2L blends have favorable thermodynamic properties. Confirm the specific efficiency rating for your model, since it varies by configuration.
