Common Faults We Diagnose & Rectify

Sudden drops in thermal comfort usually stem from discrete component degradations. Our technicians identify root causes within 20 minutes on site.

mode_fan_off

No Cooling / Warm Air Flow

The blower fan operates smoothly, but output air remains at room temperature. Usually triggered by compressor lockup, blown run capacitor, or zero suction line pressure.

Root Risk: Compressor burnout warning
volume_up

Grinding, Rattling & Shaking

High-decibel screeching or rhythmic rattling indicates loose blower wheel bushings, degraded condenser fan motor bearings, or unseated compressor isolator feet.

Root Risk: Bearing seizure hearing_disabled
electric_bolt

Continuous MCB / Fuse Tripping

The distribution breaker trips within seconds of AC startup. Points to dead short circuits in the hermetic compressor motor, shorted IPM modules, or pinched control harnesses.

Root Risk: Household power surge power_off
water_drop

Severe Indoor Water Dripping

Water overflowing onto internal walls indicates clogged condensate siphon drains, cracked polystyrene drain pans, or evaporator ice-thaw cycles caused by low gas charge.

Root Risk: Wall paint & drywall rot plumbing
error

Cryptic Display Error Codes

Flashing digital codes (E1, E6, F3, CH05, etc.) signal communication bus timeouts, ambient thermistor drift, or inverted inverter motor phase sequencing.

Root Risk: Complete system freeze memory

Frequently Asked Questions

Everything you need to know about our diagnostic inspections and repair policies.

What if I choose not to repair after the diagnostic inspection? expand_more
You only pay the nominal ₹299 inspection visit charge. You will still receive our complete 32-point digital diagnostic report outlining exactly what is wrong, which parts require replacement, and their recommended specifications.
How long does a typical AC repair take? expand_more
Most electrical, capacitor, fan motor, and sensor repairs are resolved within 45 to 90 minutes right at your premises, as our vans carry frequent OEM spares. Advanced PCB micro-soldering or complex compressor refitting usually takes 24 to 48 hours in our technical lab.
Are replaced spare parts covered under warranty? expand_more
Yes. Every genuine spare part replaced by Uni Finish comes with a full 90-day comprehensive warranty. If the identical component fails within 90 days, we replace it completely free of charge with zero service fee.
Do you service inverter ACs and multi-split systems? expand_more
Absolutely. Our HVAC engineers are certified to work with dual-inverter, variable refrigerant flow (VRF/VRV), and ductable split systems across all leading brands like Daikin, Mitsubishi, LG, Voltas, Carrier, and Hitachi.
