24/7 Commercial Refrigeration & Electrical Repair in Dallas, TX | TECL‑Licensed Techs

Common Issues We Fix (Compressors, Breakers, GFCI/AFCI, Ice Machines)

Refrigeration: Compressors, Leaks, Coils, Thermostats, TXV/EEV, Defrost

Our team fixes all types of commercial refrigeration and HVAC systems. Common problems include:

• Compressor failure

• Refrigerant leaks

• Iced evaporator coils

• High head/low suction pressure

• TXV/EEV faults

• Defrost failures

• Door gasket/air infiltration

• Control board/thermistor faults

Electrical: Tripping Breakers, Loose Neutrals, Voltage Drop, Surge/Lightning

Electrical problems create safety risks and equipment damage. We repair:

• Tripping breakers

• Loose neutrals

• Voltage drop

• Surge/lightning damage

• Burnt contacts/failed contactors

• Bad capacitors/relays

• Three‑phase imbalance/phase loss

• Harmonics/power quality issues

Advanced: High Head/Low Suction, Door Gasket/Air Infiltration, Phase Loss, Harmonics

Complex problems require expert analysis. We troubleshoot defrost heater and timer failures, TXV (thermostatic expansion valve) and EEV (electronic expansion valve) issues. Air infiltration from worn gaskets, door sweeps, and hinges causes temp drift and frost. We diagnose high head or low suction pressure from dirty condensers, restrictions, or undercharge. Loose neutrals in panels/subpanels cause flicker and nuisance trips. We handle diagnosis and remediation of surge or lightning damage impacting boards, contactors, and controls. Harmonics and poor power factor contribute to overheating and trips. We monitor for three‑phase imbalance and phase loss with protective controls to prevent compressor damage.

Our Diagnostic Tools & Process

IR Thermal Imaging, Megger Testing, Power Quality Analysis

Infrared thermography (thermal imaging) reveals hidden problems like overheating connections or insulation failures. Our insulation resistance tester (megohmmeter) finds deteriorating wire insulation before it causes failures. Using a power quality analyzer, we identify voltage problems affecting your equipment.

Leak Isolation (Electronic, UV Dye, Soap Bubble), Nitrogen Pressure Test

We use electronic detection, UV dye, and nitrogen pressure tests to find refrigerant leaks accurately. Soap bubble testing at suspected joints/valves confirms pinpoint leaks.

Deep Vacuum to 500 Microns, Superheat/Subcooling Verification

We pull a deep vacuum using a vacuum pump and micron gauge, then weigh in the exact charge. We verify superheat and subcooling for optimal performance.

Line Set & Service Valves Inspection; OEM Parts on Hand

We inspect line sets and service valves for kinks, restrictions, rubbing leaks, and proper valve operation. We stock common parts like filter-driers, contactors, and capacitors for same-day repairs. For special parts, we have fast OEM sourcing.

Tools used:

• Multimeter

• Clamp meter

• Thermal camera

• Power quality analyzer

• Megohmmeter

• Manifold gauges

• Electronic/UV/soap bubble leak detection
