Why Is My AC Not Cooling? Causes & Solutions
Updated January 2026 · 2 min read
Quick Answer
An AC not cooling is usually caused by dirty filters, low refrigerant (gas), a faulty compressor, or blocked outdoor-unit airflow. In Mumbai humidity, clogged drains and frozen coils are also common. Book a verified AC technician on ProFixer for diagnosis — most fixes are same-day when slots allow.
Key Takeaways
- Clean or replace filters every 2–4 weeks in summer.
- Low gas needs a leak check before refill — topping up alone is temporary.
- Outdoor-unit clearance (30 cm+) improves cooling efficiency.
- Frozen evaporator coils often mean airflow or gas issues.
- Professional diagnosis costs less than repeated DIY attempts.
When your split or window AC blows warm air in Mumbai's heat, the problem is rarely a single fault. Most households see cooling drop because of restricted airflow (dirty filters, blocked vents), refrigerant issues (slow leaks after monsoon vibration), or electrical wear on capacitors and compressors.
Start with filter cleaning — it is free and fixes mild cooling loss. If ice forms on the indoor coil, turn the AC off for 30 minutes; persistent icing needs a technician. Gas refill without leak repair wastes money; a good visit includes vacuum, leak test, and a measured charge.
ProFixer connects you with verified AC technicians across Mira Road, Bhayandar, Borivali, and greater Mumbai. Transparent pricing, same-day slots when available, and a 30-day workmanship warranty on eligible repairs.
