24/7 Commercial Rooftop Refrigeration Repair in Dallas-Fort Worth (RTU Experts)

Commercial Units We Service: RTUs, Walk-Ins, Racks, and Cases

Rooftop packaged condensing units (RTUs) and split systems

We service all major brands of rooftop units. Our techs handle both packaged systems and split configurations with remote evaporator coils inside your building.

Walk-in coolers and freezers with rooftop condensing units

Your walk-in depends on reliable rooftop equipment. We diagnose and repair condenser coil issues, head pressure control problems, and refrigerant charge issues quickly.

Display cases, reach-ins, prep coolers, and chef lines

Every refrigerated unit in your operation needs proper cooling. We service the complete cold chain from rooftop to display case.

Ice machines and bin systems

Ice machines require precise temperature control. We fix cycling issues, low production, and temperature problems.

Refrigeration racks and controls

Complex rack systems need experienced technicians. We handle parallel compressor racks and advanced control systems.

Evaporator coils, condenser coils, TXV/EEV valves, EC motors

From thermostatic expansion valves to electronic expansion valves (TXV/EEV), we service all critical components. We also upgrade to energy-efficient EC motors and VFDs.

Fast Emergency Repair & Response

24/7 dispatch, live phone support, same-day/next-day availability

Real people answer our phones day and night. We dispatch immediately for emergencies and offer same-day service for urgent repairs.

Two-hour arrival windows across Dallas-Fort Worth

We give you accurate arrival times, not all-day windows. Our GPS-tracked trucks mean you know exactly when help arrives.

Remote temperature/alarm triage and guided shutdowns

Sometimes we can help over the phone. Our techs guide you through safe shutdowns and temporary fixes to minimize product loss.

Before We Arrive (5-minute checklist):

• Move highest-risk product to colder storage if available.

• Verify doors/gaskets are sealed; limit openings.

• Clear debris from rooftop condenser intake (if safe).

• Note active alarms/error codes and recent changes.

• Avoid repeated resets to prevent compressor damage.

Minimizing downtime, product loss, and cold chain risk

We understand operational disruption costs money. Our goal is getting you running fast while maintaining food safety standards.

Common Issues & Warning Signs

Temperature fluctuations and warm cases

Rising temperatures mean trouble. Don't wait for complete failure—call at the first sign of warming.

Ice buildup or frost on coils; clogged drains

Ice indicates airflow problems or defrost control failures. We fix defrost heaters and clean clogged drains.

Compressor, fan, or motor failures and belt issues

Strange noises often mean mechanical problems. We stock common belts and motors for quick repairs.

Refrigerant leaks and low charge (microchannel leaks)

Using electronic leak detection and nitrogen pressure tests, we find and fix leaks fast. We handle tricky microchannel repairs too.

Electrical faults, alarms, and short cycling

Electrical issues cause premature wear. We diagnose control problems and fix short cycling.

Head Pressure Control, TXV/EEV Calibration, and Coil Performance

Improper superheat and subcooling damage compressors. We calibrate systems for peak efficiency. Fan cycling/head pressure control valve failures (especially in cold weather) can cause flooded condensers or low receiver levels - we install/adjust head pressure controls to stabilize operation.

Defrost control or heater failures

Failed defrost controls create ice blocks. We repair or replace controls and heaters quickly.

Rapid Diagnostics & Repair Process (Leak Detection, 500-Micron Evacuation)

Initial assessment, lockout/tagout, and rooftop safety check

Safety comes first. We follow OSHA protocols including proper lockout/tagout and fall protection on rooftops.

Electronic Leak Detection & Nitrogen Pressure Testing

Our diagnostics pinpoint problems accurately. We use advanced tools to find even tiny leaks.

What's Included in Diagnostics:

• Visual inspection and safety/LOTO.

• Electronic leak check and nitrogen pressure test.

• Electrical checks, compressor/fan testing.

• Superheat/subcooling measurements and control verification.

• Written estimate with photos and readings.

EPA-Compliant Recovery and Deep Vacuum (to 500 Microns)

We follow EPA regulations for refrigerant recovery and evacuation. Deep vacuums to 500 microns ensure moisture-free systems.

Brazing with nitrogen purge, filter-drier replacement, and verification

Proper brazing prevents future leaks. We always purge with nitrogen and replace filter-driers.

Airflow checks, superheat/subcooling calibration, and controls testing

After repairs, we verify proper operation. Every system gets tested thoroughly.

Documentation: Photos, Readings, and Compliance Logs

You receive complete documentation and compliance logs for your records, including photos and system readings.

Pricing & Cost Factors (Transparent Estimates)

Unit type, size, and rooftop accessibility

Larger units and difficult access affect pricing. We provide clear estimates upfront.

Parts availability, refrigerant type/charge, and labor time

Common parts stay on our trucks. Special orders and refrigerant type impact costs. OEM parts typically carry manufacturer warranty while labor warranty varies by installer - we offer custom warranty terms for multi-site SLAs.

Roof access, crane time, curb adapters, and permits

Major replacements may need cranes and permits. We handle coordination.

Emergency/after-hours rates

Emergency service costs more, but we're transparent about rates.

Diagnostics fee, estimates, and multi-site/contract pricing

Diagnostic fees apply toward repairs. Multi-site operators get volume discounts.

Ways to Control Costs:

• Enroll in PM plans to catch issues early.

• Approve like-for-like parts to speed turnaround.
