What You Need to Know Before Summer Hits
Summer is weeks away and if you operate a grocery store, supermarket, convenience store, or large cold storage facility in El Paso or the surrounding region, your low-temperature refrigeration system is about to face its toughest test of the year.
Triple-digit heat doesn't just make your customers uncomfortable. It places extreme mechanical stress on every component of your low-temp refrigeration infrastructure, from frozen food display cases and walk-in freezers to multi-deck rack systems and large cold storage compressor rooms. When outdoor temps hit 105°F, the laws of physics work against you, and a system that was running fine in March can start struggling in June.
At AM Refrigeration, low-temperature refrigeration for commercial grocery operations and large cold facilities is a core part of what we do. We've designed, installed, and serviced these systems across El Paso, Las Cruces, Anthony, Horizon City, Socorro, Sunland Park, Santa Teresa, Canutillo, Fabens, and throughout West Texas and Southern New Mexico. We know what summer does to your equipment and we know how to make sure it doesn't shut you down.
What Is Low-Temperature Refrigeration and Why Does It Demand Special Attention?
Low-temperature refrigeration refers to systems that maintain product temperatures at or below 0°F. These are the systems behind your frozen food aisles, ice cream cases, freezer walk-ins, blast freezers, and large cold storage rooms.
Unlike medium-temperature refrigeration (produce cases, dairy coolers, deli units), low-temp systems run harder, require more precise refrigerant management, and are significantly more vulnerable to heat-related performance degradation. In a desert climate like El Paso's, the condensing side of a low-temp system is working to reject heat into ambient air that's already 100°F+. That is an enormous mechanical burden.
The consequences of low-temp system failure are immediate and expensive:
• Frozen product thaws within hours
• Ice cream, meat, seafood, and frozen prepared foods become unsellable
• Product loss in a mid-size grocery store can exceed $20,000 per incident
• Emergency after-hours repair and refrigerant recovery add thousands more
• Health code violations and potential closure if temperatures are not restored quickly
The bottom line: low-temperature refrigeration is mission-critical infrastructure. It deserves to be treated that way.
How El Paso's Summer Heat Attacks Your Low-Temperature Systems
Understanding the mechanics helps you appreciate why proactive service matters so much in our region.
1. Condensing Temperature Rise Reduces System Capacity
Every low-temp refrigeration system has a design condensing temperature — the outdoor ambient condition the system was engineered to perform in. Most commercial low-temp equipment is designed for ambient temperatures up to 95°F. El Paso regularly exceeds that during June, July, August, and September.
When condensing temperatures rise beyond design limits, your system's capacity drops. A low-temp compressor that could maintain -10°F at 95°F ambient may only hold -2°F at 110°F ambient leaving your frozen food cases warmer than they should be, even while the compressor runs continuously.
2. Compressor Overload and Premature Failure
High condensing pressure forces compressors to run hotter and harder. Over time and sometimes within a single season this leads to:
• Motor winding overheating
• Oil breakdown and lubrication failure
• High-pressure lockouts
• Compressor burnout requiring full replacement
In grocery rack systems serving multiple frozen food cases simultaneously, a compressor failure doesn't just take out one case. It can take out an entire section of your frozen food department.
3. Evaporator Coil Defrost Issues Compound in Heat
Low-temperature evaporator coils require regular defrost cycles to clear frost buildup. In extreme heat conditions, improperly calibrated defrost timing can lead to:
• Excessive frost accumulation reducing airflow and cooling capacity
• Product temperatures climbing during and after defrost cycles
• Cases struggling to recover to setpoint before the next defrost cycle begins
This is a common issue we see in El Paso grocery stores during summer and it's easily corrected with proper calibration by an experienced commercial refrigeration technician.
4. Door Gaskets and Case Seals Fail Faster in Heat
Display case door gaskets degrade faster in high-temperature environments. A cracked or misaligned gasket on a frozen food case is costing you:
• Lost cold air and infiltration of warm, humid air
• Increased compressor run time
• Frost buildup on case interiors
• Higher energy bills every single day
For a 20-door frozen food section, worn gaskets can add hundreds of dollars monthly to your utility costs before you even account for the added compressor wear.
What Grocery Stores and Supermarkets in El Paso Need to Check Right Now
If you operate a full-service grocery store or supermarket anywhere in El Paso, Horizon City, Socorro, Fabens, Anthony, or the surrounding region, here is what should be on your pre-summer checklist:
✔ Rack System Inspection
Your refrigeration rack is the heart of your system. Before summer, have a certified technician inspect: compressor oil levels and condition, refrigerant charge (both low-temp and medium-temp circuits), condenser coil cleanliness and airflow, suction and discharge pressures under load, safety controls and high-pressure cutouts, and liquid line solenoids and expansion valves.
✔ Condenser Cleaning
Dirty condensers are one of the most common and most preventable causes of summer refrigeration failures. El Paso's dust and desert environment accelerates condenser fouling. Condensers on grocery rack systems should be cleaned before peak summer and monitored throughout the season.
✔ Defrost Controls and Termination Sensors
Have your defrost timers, termination thermostats, and drain heaters inspected and calibrated. Improperly terminating defrosts during peak summer heat cause significant case temperature problems.
✔ Display Case Gaskets and Door Alignment
Walk your entire frozen food section and dairy section. Check every gasket for cracking, gaps, and deformation. Check door alignment and hinges. Small investments here prevent large compressor loads all summer long.
✔ Monitoring System Review
If you have a refrigeration monitoring or building management system (BMS), verify that alert thresholds are properly set and that your team knows how to respond to alarms. In summer, an unresolved alert at midnight can become a $15,000 product loss by 6 AM.
What Convenience Stores and C-Stores Need to Know
For C-store operators throughout El Paso, Las Cruces, Sunland Park, Santa Teresa, and surrounding communities, low-temperature refrigeration includes frozen beverage machines and dispensers, ice cream reach-in cases, frozen food doors and small walk-in freezers, and ice merchandisers. These systems are typically smaller than grocery rack systems but are just as vulnerable to El Paso's summer heat — and often receive far less proactive maintenance.
The biggest C-store refrigeration risk in summer is compressor failure in reach-in freezers. These units typically have self-contained refrigeration systems with small compressors that run continuously during hot weather. Dirty condensers, low refrigerant, or failing start components cause these units to fail during peak summer months.
A C-store that loses its frozen merchandise section during a West Texas summer weekend loses significant revenue and if a unit fails on a Friday afternoon, finding emergency service can be difficult without an established service relationship.
AM Refrigeration provides service agreements for C-store operators across the El Paso region that include scheduled maintenance, priority emergency response, and equipment monitoring. If your C-store doesn't have a service agreement in place before summer, now is the time.
Large Cold Storage Facilities: The Stakes Are Even Higher
For distribution centers, food processing operations, cold storage warehouses, and large commercial cold facilities serving the El Paso region including operations in Dona Ana County, Otero County, and Hudspeth County, the engineering demands of low-temperature refrigeration are more complex, and the cost of failure is exponentially higher.
Large cold storage systems typically involve:
• Industrial-grade screw or reciprocating compressors
• Ammonia or large HFC refrigerant systems
• Evaporative condensers or large air-cooled condenser arrays
• Multiple refrigeration circuits serving different temperature zones
• Sophisticated controls and safety systems
In a facility storing millions of dollars in frozen product, a single compressor failure or refrigerant leak event can result in catastrophic losses. For these operations, preventative maintenance is not optional, it is a core business continuity strategy.
AM Refrigeration has experience working with large commercial cold storage operations throughout West Texas and Southern New Mexico. Our team understands the engineering requirements, safety protocols, and regulatory compliance considerations that large cold facilities demand. If you manage a large cold storage operation in the El Paso region and don't have a documented service and maintenance plan in place, contact us for a facility assessment before summer.
Commercial HVAC: What Large Facilities and Restaurants Need to Know About Equipment Decisions This Spring
Low-temperature refrigeration and commercial HVAC don't operate independently, in fact, in most commercial facilities they interact. In grocery stores, restaurants, and large commercial spaces, the HVAC system directly affects how hard your refrigeration has to work. When a restaurant's HVAC system is undersized or poorly maintained, ambient temperatures rise which increase the load on every refrigeration unit in the space.
Buying Commercial HVAC Equipment This Spring: What to Know
Size for your actual load, not just your square footage.
Proper HVAC sizing in West Texas requires load calculations that account for El Paso's extreme solar gain, high ambient temperatures, and your facility's occupancy and equipment heat load. An undersized commercial HVAC system in El Paso will fail prematurely and struggle to maintain comfort during summer peaks.
Plan your purchase before June, not during it.
Lead times for commercial rooftop units and large HVAC equipment have extended across the industry. If you wait until your system fails in the middle of summer to start the replacement process, you may be looking at weeks of downtime. Spring is the right time to evaluate aging equipment and place orders.
Specify equipment rated for high-ambient conditions.
Standard commercial HVAC equipment is rated to operate efficiently at 95°F ambient. West Texas regularly exceeds that for months at a time. When specifying new equipment for El Paso facilities, select units with high-ambient ratings appropriate for your climate conditions.
Include refrigeration compatibility in your HVAC design.
In grocery stores and food facilities, HVAC system design must account for refrigeration case heat loads and the interaction between the refrigeration condensers and the HVAC system. Systems designed in isolation frequently underperform and create comfort and efficiency problems.
