🧊 Walk-In Cooler & Freezer Services

🔧 Compressor & Evaporator Replacement — Walk-In Coolers & Freezers

Allbrands Refrigeration specializes in commercial compressor and evaporator replacement for walk-in cooler and walk-in freezer systems. Every replacement is performed using OEM-matched components, verified system sizing, and documented startup and commissioning procedures to ensure reliability, compliance, and warranty protection.

Compressor and evaporator failures are rarely isolated events. They are typically caused by underlying electrical faults, refrigerant issues, airflow problems, oil contamination, or control failures. Our replacement process focuses on root-cause correction, not just component swap-outs, to prevent repeat failures and costly downtime.

🔍 Documented Root-Cause Analysis (Included)

Every compressor replacement begins with a documented failure analysis to identify the true cause of failure. This includes evaluation of electrical components, refrigerant conditions, airflow performance, oil quality, and control logic. Correcting the root cause protects manufacturer warranties and reduces the risk of repeat compressor failure.

⚙️ Walk-In Compressor Replacement

We replace scroll, reciprocating, and semi-hermetic compressors for both medium-temperature and low-temperature walk-in applications. Each compressor is properly matched to system capacity, refrigerant type, voltage, phase, and operating temperature range to ensure stable performance and long equipment life.

---

❄️ Refrigerant Applications & Compliance

We service and install compressors using approved commercial refrigerants including R404A, R448A, R449A, R134a, and compliant low-GWP alternatives. All refrigerant handling, charging, and documentation are performed in accordance with OEM specifications and EPA regulations.

🔌 Electrical & Start Component Corrections

Compressor replacement includes inspection and correction of all related electrical components. This may include contactors, overloads, start relays, run capacitors, wiring repairs, voltage verification, and amperage checks to ensure proper compressor protection and startup reliability.

---

🛢️ Oil Management & System Cleanup

Following compressor failure, we address oil contamination and system cleanliness. Services may include acid cleanup, oil correction, filter-drier replacement, and contamination mitigation to protect the sealed refrigeration system and prevent premature component damage.

---

🧪 Refrigerant Recovery & Commissioning

All replacements include full refrigerant recovery, deep evacuation, precision charging, and system commissioning under operating load conditions. This ensures correct pressures, proper refrigerant balance, and stable system operation before returning equipment to service.

---

❄️ Evaporator Coil Replacement & Upgrades

We replace and upgrade medium-temperature and low-temperature evaporator coils with proper BTU matching to the condensing unit. Airflow performance, defrost strategy, and control compatibility are verified to maintain even product temperatures and prevent icing issues.

---

🧊 Defrost & Airflow Components

Defrost systems and airflow components are evaluated and corrected as part of evaporator service. This may include defrost heaters, timers, termination sensors, fan motors, drain heaters, and condensate management to prevent frost buildup and water damage.

---

🎛️ TXV & EEV Control Upgrades

Expansion valves are inspected and replaced or upgraded as needed. TXV and EEV adjustments are performed to stabilize suction pressures, improve temperature consistency, and optimize system efficiency across the walk-in space.

---

🧪 Post-Repair System Verification

Before completion, all systems undergo full operational verification. This includes pressure checks, superheat and subcooling confirmation, defrost cycle testing, controller calibration, alarm verification, and confirmation of stable temperatures within compliance ranges.

All work is fully documented for inspections, warranty claims, and facility maintenance records.

🧰 Surplus & Alternate Compressor Options (Availability Varies)

In some cases, new, unused OEM-compatible compressors may be available as surplus depending on application and location. When compatible, these options can help reduce replacement delays while maintaining proper system sizing, efficiency, and compliance.

✅ All compressors—standard or surplus—are:

✅Application-matched to system capacity

✅Verified for refrigerant, voltage, phase, and temperature class

✅Installed with full system verification and documented commissioning

📞 Availability varies by location. Ask during scheduling for local options.
