2025–2026 Refrigeration Laws & Standards for Mortuary & Morgue Equipment

Recent changes to U.S. refrigeration regulations affect how new mortuary coolers, walk-in mortuary rooms, and commercial refrigeration equipment are designed, installed, and serviced. While every facility should confirm specifics with its mechanical contractor and local code officials, here is a high-level overview of what’s changing in 2025–2026.

1. EPA HFC Phasedown & Low-GWP Refrigerants (AIM Act)

Under the American Innovation and Manufacturing (AIM) Act, the EPA is phasing down high-GWP hydrofluorocarbons (HFCs) used in many commercial refrigeration systems, including cold-storage and walk-in applications. The phasedown uses an allowance system that steadily reduces the national supply of HFCs through 2036. :contentReference[oaicite:0]{index=0}

• EPA has finalized rules that push new equipment toward lower-GWP refrigerants, often targeting a GWP of 700 or lower for many new systems beginning in 2025, with additional sector-specific limits and dates following. :contentReference[oaicite:1]{index=1}
• Cold-storage and warehouse applications are seeing proposed limits around GWP 700 for new systems starting in 2026, which can impact large walk-in and remote-condensing designs. :contentReference[oaicite:2]{index=2}
• EPA issues annual HFC production and consumption allowances, including specific allocations for 2025 and 2026, which can affect availability and price of some refrigerants. :contentReference[oaicite:3]{index=3}

Note: Federal rules are evolving and may be reconsidered or modified. Some states also adopt their own refrigerant restrictions that can be more stringent than federal requirements.

2. DOE Energy Efficiency Standards for Commercial Refrigeration

The U.S. Department of Energy (DOE) has finalized updated energy conservation standards for commercial refrigerators, freezers, and refrigerator-freezers, which include equipment categories similar to many mortuary and morgue systems. :contentReference[oaicite:4]{index=4}

• Final rules were issued in late 2024 and early 2025, with compliance dates starting later in the decade, depending on equipment class.
• These standards push manufacturers toward higher efficiency coils, fans, controls, and compressor technologies, which can influence the design and cost of new mortuary coolers.

3. ASHRAE Safety Standards for Refrigeration Systems

ANSI/ASHRAE Standard 15-2024 and related addenda govern safety requirements for many refrigeration systems, including those using newer mildly flammable A2L refrigerants. Recent addenda in 2025 update pressure-relief and refrigerant change-out requirements. :contentReference[oaicite:5]{index=5}

• When switching from older HFCs to low-GWP refrigerants, contractors must follow updated safety, ventilation, relief, and classification requirements.
• Mortuary cold rooms are typically treated similarly to other cold storage/medium-temperature chambers, so coordination between your cooler manufacturer and mechanical contractor is critical.

Understanding Ambient Room Temperature

The surrounding ambient room temperature has a direct impact on mortuary cooler performance, energy use, and component life. Even the best equipment can struggle in a poor environment.

Mortuary coolers perform best in controlled spaces between about 65°F and 75°F. When the room is consistently hotter:

• The compressor works harder and runs longer to maintain body storage temperatures.
• Energy consumption rises and operating costs increase.
• Component wear accelerates, shortening the service life of the cooler.

Forensic facilities, high-volume care centers, and funeral homes with small mechanical rooms should pay close attention to room ventilation, exhaust, and make-up air around their self-contained or remote-condensing mortuary coolers.

Different Types of Mortuary Refrigeration Systems

Mortuary refrigeration systems generally fall into two main categories:

• Self-Contained Systems — Compact, plug-and-play mortuary coolers where the condensing unit is integrated into the cabinet. These are ideal for smaller funeral homes, low-volume medical facilities, and installations where simplicity is key.
• Remote Condenser Systems — The evaporator is inside the cooler while the condensing unit is located outdoors or in a separate mechanical area. This design is common in high-volume morgues, walk-in mortuary coolers, and cold-storage facilities where noise and heat must be kept away from sensitive areas.

Selecting the right system depends on your facility layout, regional climate, capacity requirements, and maintenance capabilities. Our team can help you compare self-contained and remote options for new projects or replacement systems.

Why Climate Matters in Refrigeration Sizing

Climate drives heat load and refrigeration demand. Facilities in hotter or more humid regions typically need larger or higher-capacity compressors, properly sized condensers, and adequate airflow to maintain stable interior temperatures.

• Warm, humid climates require additional capacity to overcome higher outdoor temperatures and moisture loads.
• Cooler, drier climates may support slightly smaller systems, but still need careful design.
• Undersized equipment can result in temperature instability, longer pull-down times, increased wear, and compliance concerns.

When we design a new mortuary cooler or walk-in system, we always consider climate data, room conditions, expected capacity, and your workflow to ensure reliable operation year-round.

Why Seasonal Changes Affect Cooler Performance

During seasonal transitions, changes in ambient temperature and humidity can stress refrigeration systems. In many regions, spring and summer bring:

• Higher condensing temperatures and longer run times
• More strain on fans, compressors, and electronic controls
• Greater potential for icing issues, drain line clogs, or nuisance alarms

Scheduling seasonal checks – particularly before the hottest months – helps ensure thermostats, condensers, evaporator fans, and controls operate at peak efficiency and prevents surprise downtime during your busiest seasons.

Annual Service: Essential for Long-Term Performance

Like any critical system, mortuary coolers require annual maintenance. A structured preventive maintenance program protects both your equipment and your license by supporting temperature consistency and compliance.

Annual service typically includes:

• Verifying proper refrigerant charge and checking for leaks
• Cleaning condenser and evaporator coils
• Inspecting door gaskets, hinges, and latches for air leaks
• Checking drain lines, pans, and defrost operation
• Confirming thermostat and temperature probe accuracy
• Reviewing alarms, monitoring systems, and record-keeping procedures

Regular maintenance helps maintain OSHA and health-department compliance, reduces energy waste, and extends compressor life. In many cases, it also supports warranty coverage.
