What causes Car AC Not Cooling?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Low AC refrigerant (gas) from slow leak — most common AC fault in Hyderabad's heat
- AC compressor clutch slipping or compressor internally failed
- Clogged cabin air filter blocking airflow across evaporator
- Dirty or damaged AC condenser reducing heat exchange efficiency
- AC expansion valve blocked causing restricted refrigerant flow

Frequently asked questions
Why is my car AC not cooling in Hyderabad summer (April–June)?
Hyderabad summers are brutal — outside temperatures of 42–45°C with full sun. Car ACs under this load reveal any weakness in the system. Most common causes in Hyderabad summer: 1) Low AC gas (gradual leak over years), 2) AC compressor struggling under peak thermal load, 3) Clogged cabin filter halving airflow, 4) Dirty condenser reducing heat exchange capacity. Metre Per Second performs a full AC system check starting with free gas pressure reading.
How much does AC gas refilling cost in Hyderabad?
AC gas (R134a) refilling at Metre Per Second costs ₹1,500–₹3,000 including gas and fitting. However, if the system had a leak that caused the gas to escape, the leak must be found and fixed first (₹2,000–₹8,000 depending on leak location) — otherwise you'll lose the new gas within months. We always perform a leak test before adding gas.
