Mercedes-Benz AC Service in KPHB, Hyderabad

GarageNation provides specialist Mercedes-Benz AC service and repair with free pickup from KPHB. Mercedes-Benz air conditioning systems use R-134a (pre-2017 C-Class, E-Class) / R-1234yf (2017 onwards — GLC, GLE, A-Class, new C-Class) and a Sanden / Denso variable displacement compressor (TRSE-series). We service the full Mercedes-Benz AC circuit — compressor, condenser, evaporator, expansion valve and HVAC controls — using Mercedes-Benz XENTRY/DAS (Star C6) for accurate system-level diagnosis. Price range: ₹1,500 (regassing) to ₹35,000 (compressor replacement).

Mercedes-Benz AC System Specifications

• Refrigerant: R-134a (pre-2017 C-Class, E-Class) / R-1234yf (2017 onwards — GLC, GLE, A-Class, new C-Class)
• Compressor: Sanden / Denso variable displacement compressor (TRSE-series)
• Evaporator target: 1–4°C; Mercedes XENTRY/DAS reads AC pressure sensors across both circuits
• Compressor oil spec: PAG 46 (R-134a) / Bitzer IsoTherma POE 68 (R-1234yf)
• Diagnostic tool: Mercedes-Benz XENTRY/DAS (Star C6)

Common Mercedes-Benz AC Problems We Fix

• Compressor clutch failure — Mercedes C-Class W205 and E-Class W213 — often misdiagnosed as refrigerant loss
• Cabin filter clogging causing no-airflow complaints — two-stage HEPA filter on S-Class, E-Class
• THERMOTRONIC dual-zone control module fault — one zone stuck cold or hot
• Condenser micro-leak from road debris — common on GLE and GLC front bumper placement

Mercedes-Benz AC Service for KPHB Owners

KPHB Colony Phase 1-9, Kukatpally is ~2 km from our KPHB workshop. We collect your Mercedes-Benz from KPHB — no need to drive to us in hot weather with no AC. Colony roads have frequent speed breakers and tight turns causing alignment and suspension wear on smaller cars. KPHB summers regularly hit 42–45°C. A refrigerant leak left unrepaired damages the compressor within 1–2 seasons — early service is always cheaper than compressor replacement.

Mercedes-Benz AC Service Process

• Mercedes-Benz XENTRY/DAS (Star C6) scan — read HVAC fault codes, compressor activation data, blend-door positions
• Refrigerant pressure check (high-side and low-side) with refrigerant station
• UV dye leak detection — trace refrigerant leaks at condenser, evaporator, hoses, and compressor shaft seal
• Regassing with correct refrigerant (R-134a) and PAG 46 (R-134a) / Bitzer IsoTherma POE 68 (R-1234yf)
• Cabin pollen filter replacement — blocked filter reduces airflow and causes musty smell
• Evaporator drain check and antibacterial treatment — prevents musty smell from mould growth
