A full teardown when cleaning is no longer enough.
Complete indoor fancoil dismantling from the wall bracket. High-pH bio-neutralizer on evaporator fins, blower-wheel immersion, drain pan declogging, motor lubrication, multi-point refrigerant gauge check. For units neglected over 12–18 months, choked blowers, heavy mold, or repeat leaks after a standard chemical clean.
What is included in full chemical overhaul.
Every unit undergoes an uncompromising mechanical disassembly down to the copper junction, restoring aerodynamic efficiency and thermodynamic heat exchange.
Complete Wall Dismounting
Full uncoupling of the evaporator chassis from its backplate mount. Disconnects wiring looms, thermistors, and primary flare connections without wall damage.
Blower Immersion Bath
Submersion of cross-flow cylindrical blower wheel in alkaline degreaser. Dissolves caked biofilm, dead mold colonies, and micro-particulates trapped inside vanes.
Bi-Directional Fin Treatment
Application of non-acidic aluminum coil restorer to both front and hard-to-reach rear coil banks. Removes micro-oxidation and opens compressed thermal airflow pathways.
Tray Sanitization & Coating
High-pressure mechanical clearance of internal condensation trough. Finished with an antimicrobial surface inhibitor to suppress future jelly algae buildup.
Bearing & Motor Calibration
Synthetic PTFE high-temperature grease applied to rubber damper bearings. Dynamic rotational balancing reduces interior blower hum and motor drag.
Digital Pressure & Electrical Audit
Manifold gauge analysis across suction and discharge lines. PCB contact check, running amp evaluation, and infrared Delta-T air outlet confirmation.
Photographic Diagnostic Log Included
Technicians record micro-photos of internal blower conditions, evaporator channels, and running pressures straight to your service portal.
Client Preparation for Teardown Operations
Work Area Readiness: Please clear a 0.75m line-of-sight radius around the indoor fancoil unit prior to technician arrival. Our HVAC engineering team deploys heavy-duty floor waterproof catchment mats and architectural rubber ladder pads to ensure total property protection.
*Condominium and High-Rise JMB/MC weekend working permits must be secured and registered by the unit owner or tenant in advance.
- 2m × 3m Heavy vinyl drop cloths
- Anti-scratch aluminum ladder buffers
- Low-splatter chemical immersion bags
- Dedicated washroom rinse shields
When is an overhaul required?
Compare your symptom patterns to avoid paying for an unnecessary overhaul, or wasting funds on a cleaning that won't solve systemic clogging.
Basic Cleaning
Condition: Serviced within 3–4 months. Light airborne dust on external filters.
Action: Water rinse of washable mesh filters, casing wipe, and airflow verify.
Chemical Cleaning
Condition: Mildly muted airflow, slight damp odor. Unit remains securely mounted.
Action: Frontal coil chemical pressure wash with catch-bag. Drainage tube flush.
Chemical Overhaul
Condition: Neglected >12 months, black mold blobs blowing out, jelly drip, recurring leaks.
Action: 100% fancoil bracket dismount, complete component soak bath, bearing lubrication.
Troubleshooting
Condition: Blinking indicator light, circuit trip, compressor lockout, warm air blast.
Action: Circuitry board probing, thermistor checks, capacitance testing, wiring diagnostics.
