Lab-Grade Precision Diagnostics in Rawalpindi and Islamabad

At Pak Electrical AC and Fridge Services, advanced refrigeration diagnostics go far beyond basic gauge readings. For modern inverter systems and complex cooling units, we utilize precise calculations including Superheat, Subcooling, and Approach Temperature to ensure factory-standard refrigerant charge and peak compressor protection.

Our Advanced Technical Diagnostic Process:

✓ Superheat Calculation: Measuring suction line temperature and evaporating pressure to protect your compressor from liquid slugging and ensure optimal cooling efficiency for R32, R410A, and R22 systems.

✓ Subcooling Analysis: Verifying liquid line temperature against condensing pressure to guarantee that 100% liquid refrigerant enters the expansion device without premature flash gas.

✓ Approach Temperature Testing: Evaluating heat exchanger efficiency by comparing condensing/evaporating temperatures directly with ambient or water/air temperatures across the coils.

✓ Psychrometric & Humidity Evaluation: Utilizing dry and wet bulb temperature analysis to determine exact indoor heat load and system performance without guesswork.

Why Precision Diagnostics Matter:

Even a slight deviation in superheat or subcooling can reduce system efficiency by up to 35% and shorten compressor life. Our lab-grade diagnostic procedures eliminate trial and error, protecting your costly inverter equipment.
