AC Blowing Warm Air
in Samastipur — All Causes Fixed

AC is on, fan is blowing, but air is warm or room temperature. This means the outdoor unit has stopped — here's every reason why.

Important difference: "AC not cooling enough" vs "AC blowing warm/room-temperature air." The second means outdoor unit has stopped completely. Indoor fan is just recirculating your room's warm air.

First Check — Mode Setting (Free Fix)

Remote check karo. COOL mode ❄️ dikhna chahiye — FAN mode 🌀 ya DRY mode 💧 nahi. FAN mode mein outdoor unit kabhi nahi chalta. Children often accidentally change the mode. Rule this out first — zero cost.

If Mode is Correct — Outdoor Unit Has Stopped

Bahar jaake outdoor unit check karo. Fan spin ho raha hai? Compressor ki deep hum aa rahi hai? Agar completely silent hai — outdoor unit ne kaam karna band kar diya hai.

Cause 01 — Capacitor Failed

Most Common — ₹400–₹900

Outdoor capacitor fails = compressor and outdoor fan both won't start = indoor fan blows warm room air. Most common at start of summer when marginal capacitors from last season give up. Same day fix.

Cause 02 — Contactor Not Closing

₹300–₹700

Burned contactor means outdoor unit never receives power. Sign: faint clicking from outdoor unit every few minutes (thermostat sending start signal) but outdoor unit stays silent.

Cause 03 — Tripped Outdoor MCB

Free Fix

Power surge tripped the outdoor MCB. Indoor unit works on its own circuit, outdoor has no power. Check DB board for tripped MCB in middle position. Reset and test.

Cause 04 — Outdoor Unit Overheating

Service Needed ₹500–₹800

In Samastipur's 44°C summer, dirty condenser coil causes overheating. Thermal protection shuts compressor off — indoor fan keeps blowing warm air — unit restarts after 1 hour cool-down. Classic pattern: cools in morning, warm air in afternoon, cools in evening. Fix: condenser coil wash + ensure 50cm clearance around outdoor unit.

💡 Outdoor Unit Check: Stand 1 metre from outdoor unit in COOL mode. Within 2 minutes you should feel warm air blowing OUT of the unit (that's the heat it's removing from your room). If nothing comes out — outdoor unit not running. Call us.
