What we inspect
Split AC
- A wall-mounted indoor unit connects to a separate outdoor unit.
- Check for indoor drips, weak airflow and whether the outdoor unit runs.
- Inspect the condensate path, coil, blower, interconnect and outdoor fan.
Inverter AC
- Variable-speed controls adjust compressor output as the room load changes.
- Record displayed codes, fan behaviour and when cooling drops.
- Check sensors, wiring, board inputs and compressor behaviour before quoting parts.
Cassette AC
- A ceiling-mounted indoor unit distributes air in multiple directions.
- Identify which outlet is weak and whether water stains appear around the ceiling panel.
- Check the filter, drain pump, float switch and access above the false ceiling.
Common AC faults
Jet cleaning
- Controlled water cleaning can remove packed dust from suitable coils and blower surfaces. The technician protects electronics and collects runoff.
Chemical cleaning
- Used selectively for stubborn deposits after inspection. The technician checks coil compatibility and rinsing access before choosing a cleaner.
Poor cooling
- Airflow, settings and outdoor heat rejection are checked before refrigerant work. Suspected leakage calls for leak diagnosis before any recharge.
Drips and noise
- A blocked drain or poorly seated pipe can cause a drip. A loose mount, worn bearing or damaged blower can cause vibration.
Installation and relocation
- Discuss mounting, piping route, outdoor access, drainage and electrical requirements before scheduling.
Refrigerant leak diagnosis and gas filling
- Check for signs of a leak and discuss repair feasibility first. Recharge uses the refrigerant type and quantity specified for the unit.
Compressor diagnosis, repair or replacement
- Check supply, starting or inverter controls and cooling circuit conditions before deciding whether compressor replacement is viable.
Indoor blower and outdoor fan
- Inspect airflow, speed and bearing noise. Discuss motor, wheel or blade replacement when damage is confirmed.
Control board and temperature sensors
- Trace intermittent shutdowns, incorrect temperature readings and start failures before quoting a board or sensor.
Drain line and insulation
- Inspect drain fall, blockages, indoor condensation and pipe insulation when water appears near the unit.
Arranging a visit in DN Nagar, Mumbai
- Read the model number from a visible label or purchase receipt.
