Walk-In Freezer Repair in Plano, TX | 24/7 Commercial Service

Common Walk-In Freezer Problems We Fix (TXV, EEV, Defrost, Compressors)

Temperature Control & Digital Controllers (Danfoss, Carel)

Temperature fluctuations often start with thermostat or controller problems. Your Danfoss or Carel controller might need recalibration or replacement. Modern controllers like Heatcraft Smart Defrost systems need expert diagnosis when alarms sound.

TXV/EEV, Superheat & Subcooling Adjustments

Thermostatic expansion valve (TXV) and electronic expansion valve (EEV) malfunctions create incorrect superheat and subcooling, leading to icing problems. We verify superheat and subcooling levels, adjust expansion valves, and check airflow for optimal performance.

Defrost Failures: Electric & Hot Gas

Excessive frosting signals defrost system failures. Whether you have electric defrost or hot gas defrost, we diagnose and repair the root cause. Our team checks timers, heaters, sensors, and hot gas valves to ensure proper defrost cycles.

Compressors, Condensing Units & Rooftop/Remote Condensers

We repair and replace compressors (including Copeland and Bitzer compressor systems), condensing units, evaporator coils, and remote and rooftop condensers/condensing units. Head pressure control valve issues and low-ambient kit problems affect year-round operation, especially during Texas weather changes.

Door Systems: Heaters, Gaskets, Closers, Strip Curtains

Door heater malfunctions, broken door closers, damaged door gaskets and door sweeps, and torn strip curtains cause warm air infiltration and energy waste. Water leaks and drain line clogs often need drain pan heater or heat tape repairs.

Refrigerant Leaks, Filter-Driers & Sight Glass

Refrigerant leaks require EPA-certified leak detection and recovery. We use nitrogen pressure testing, electronic leak detectors, and UV dye for accurate leak detection. Low charge issues and filter-drier or sight glass problems impact energy efficiency. We handle refrigerant recovery and reclaim according to federal protocols, working with R404A, R448A, R449A, and other refrigerants.

Insulation, Vapor Barriers & Floor Heater/Frost Heave

Vapor barrier and insulated panel failures cause ceiling frost. Floor heater problems lead to frost heave in your freezer floor. We also inspect EPR valve operation and handle structural issues that affect temperature control.

Early warning signs to watch for:

• Rising box temps or longer run times

• Frequent manual defrosts or excessive frost/ice

• Ice around doors/panels; water on floors

• Unusual noises or vibration

• Higher energy bills

Our Repair Process (EPA 608, Leak Detection, Documentation)

Diagnostics & Electrical/Mechanical Testing

We start with thorough on-site troubleshooting to identify all issues, not just the obvious ones. We test electrical and mechanical components including compressors, fans, controls, pressure switches, and EPR valve operation.

Refrigerant Recovery, Reclaim & Charging

Our EPA Section 608-certified technicians handle refrigerant recovery and reclaim according to federal protocols. When needed, we perform complete system evacuation, pressure testing, and recharge to manufacturer specifications.

Performance Verification & HACCP Records

Performance verification includes temperature pull-down testing, data logging, and complete documentation for HACCP documentation requirements and insurance purposes. Throughout the service, we maintain clear timelines and constant communication to minimize your downtime.

Plano Service Areas & Nearby Cities

We know Plano's commercial districts inside and out. From Legacy West to Downtown Plano, West Plano to East Plano, and the busy Preston Road/SH 121 corridors, we're minutes away from your location.

Our service extends throughout North Dallas including Frisco, Allen, McKinney, Richardson, Carrollton, The Colony, and Addison. Emergency repair and same-day service appointments are scheduled based on call volume, with true emergencies always taking priority.

Don't Let Product Loss Hurt Your Business

Every hour of freezer downtime risks thousands in inventory. Our emergency team is standing by 24/7.

Brands & Equipment (Kolpak, Heatcraft/Bohn/Russell, Copeland, Bitzer)

Our technicians are trained on most major walk-in freezer and cooler brands. We service Kolpak, Norlake, Bally, Master-Bilt, and Heatcraft/Bohn/Russell systems. We're experts with Copeland, Bitzer, and Tecumseh compressors.

We also repair True, Hoshizaki, Turbo Air, Hussmann, Hillphoenix, and Arctic Air equipment. Whether you have reach-ins, walk-ins, low-temp applications, mixed systems, or remote and rooftop condensers, we have the expertise and parts to fix it.

Preventive Maintenance Plans for Walk-In Freezers

Smart operators know that preventive (preventative) maintenance costs far less than emergency repairs. Our maintenance plans reduce unexpected failures, improve temperature stability, and extend equipment life by years.

Maintenance Checklist:

• Clean condenser/evaporator coils and verify airflow

• Inspect/replace door gaskets, sweeps, and strip curtains

• Clear drains; test drain pan heater/heat tape

• Calibrate defrost schedules and controllers

• Verify superheat/subcooling; adjust TXV/EEV

We also offer condenser cleaning, door alignment, head pressure control checks, and expansion valve optimization. We schedule service around your business hours with quarterly or biannual options that fit your usage patterns and budget.

Compliance & Temperature Monitoring (Texas Food Rules, ASHRAE)

Meeting Texas Food Establishment Rules and health codes requires proper documentation. We support your HACCP logs with temperature verification and sensor calibration services.

Our team can set up remote monitoring and data logging systems for audits and inspections. We ensure compliance with all Texas health and safety code requirements and ASHRAE standards.

Calibration Services

We provide thermometer, probe, and controller calibration certificates for inspectors.

System Optimization

Our technicians configure alarm setpoints, door heater controls, and defrost schedules according to ASHRAE standards and best practices.

Energy Efficiency Upgrades & Refrigerant Retrofits (R404A to R448A/R449A)

Lower your energy bills with smart upgrades. ECM evaporator fan motors, LED lighting, and strip curtains can cut energy use significantly. Door heater optimization, auto-closers, and gasket upgrades prevent waste.

We offer retrofit options from R404A to newer refrigerants like R448A or R449A where applicable, meeting environmental regulations while maintaining performance.

Advanced Controls

Head pressure control valve tuning and low-ambient kit installation ensure year-round efficiency. EPR valve and expansion valve optimization maintains stable temperatures while using less energy.

Temporary Cold Storage & Product-Saving Options

When breakdowns happen, we help protect your inventory. Our rapid stabilization steps can save products during repairs. We maintain partnerships for portable freezer rentals and can arrange short-term solutions quickly.

When appropriate, we'll guide you through dry ice use and safe product transfer to minimize losses.

Repair vs. Replace & New Installation Support

Sometimes repair makes sense. Sometimes it doesn't. We'll be honest about when repair is cost-effective versus when replacement is smarter—considering age, repeated leaks, and obsolete parts availability.

If you need new equipment, we provide specification support for walk-in boxes, condensing units, and controls. Proper commissioning includes vacuum, charge, pull-down time verification, and complete documentation.

Pricing, Cost Factors & Payment Options

We believe in transparent pricing with upfront estimates—no surprises. We accept credit cards and POs; Net-30 available for approved accounts.

Pricing & Cost Factors:

• Diagnostic time and complexity

• Parts and refrigerant type/quantity (R404A vs R448A/R449A)

• After-hours/holiday rates vs. standard hours

• Accessibility (rooftop/remote condensers) and site conditions

• Repair vs. replace considerations (age, leaks, obsolete parts)

When equipment is beyond economical repair, we'll provide options and help you make the best decision for your business.
