Emergency Aircon Repair in Makati & Taguig — Fixed Right, First Time
Manila’s brutal heat and 85% humidity trap dust, mold, and sludge inside your evaporator coils. This restricts cold airflow, spikes your Meralco electricity bill, and burns out your compressor.
We don’t just rinse your filters — we deep-clean, sanitize, and recalibrate your entire cooling system.
Aircon Failure Triage Matrix
Identify your system’s symptom below. Our service vans carry factory-matched replacement parts for immediate on-site repair.
Warm or Weak Airflow
Possible Cause: Refrigerant leak, failed dual-run capacitor, or seized compressor motor windings.
Indoor Water Infiltration
Possible Cause: Clogged condensate drain line, cracked drain pan, or improperly pitched indoor unit.
Loud Rattling or Grinding
Possible Cause: Worn fan motor bearings, unbalanced blower wheel, or loose compressor mounts.
Shuts Off After 2 Minutes
Possible Cause: Malfunctioning PCB control board, overheating thermistor sensor, or high-pressure trip.
Trips Main Circuit Breaker
Possible Cause: Grounded compressor coil, shorted wiring harness, or burnt electrical contactor switch.
Burning Chemical Smell
Possible Cause: Overheating fan motor windings, melting wire insulation, or electrical arc on terminal block.
Factory-Matched Component Replacement
Complete Aircon Repair Capabilities
We don’t guess. We test electrical resistance, pressure drops, and mechanical load to pinpoint the exact broken part.
STEP 01 • COMPRESSOR
Compressor Diagnostics & Replacement
When the compressor fails, your unit runs without producing cold air. We test internal windings, source brand-matched replacement compressors, vacuum the lines, and run stress tests.
STEP 02 • ELECTRONICS
PCB Control Board Repair & Swap
Error codes, unresponsive remotes, or sudden shutoffs point to a failed PCB
board. We run circuit diagnostics to repair minor board faults or install
factory-compatible replacement modules.
STEP 03 • AIRFLOW MOTOR
Fan Motor Replacement
Weak airflow or screeching noises stem from failing indoor blower or outdoor condenser motors. We replace worn fan motors with exact voltage and RPM spec matches.
STEP 04 • ELECTRICAL
Dual-Run Capacitor Replacement
A weak capacitor prevents your compressor and fan motor from starting up. We test microfarad ratings and replace worn capacitors on the spot to protect your compressor from burning out.
STEP 05 • REFRIGERANT
Leak Detection & Refrigerant Recharge
Refilling Freon without fixing the copper pipe leak wastes your money. We use digital pressure gauges to locate the exact leak, braze the joint securely, and recharge to factory spec.
STEP 06 • WIRING & SAFETY
Electrical Wiring & Contactor Repair
Burnt contactor switches, loose terminal blocks, or melted wiring are dangerous fire hazards. We rewire shorted connections and replace pitted contactors with heavy-duty components.
STEP 07 • DRAINAGE
Drainage System & Leak Restoration
Water damage in condos is caused by cracked drain pans or sludge blockages. We clear drain line blockages, seal damaged pans, and adjust drain pitch to eliminate overflow leaks for good.
STEP 08 • SENSORS
Thermostat & Sensor Calibration
Faulty temperature thermistors cause your AC to run continuously or turn off before cooling the room. We test resistance levels and replace faulty sensors to restore accurate cooling.
STEP 09 • DIAGNOSTICS
Multi-System Root Cause Overhaul
When an aircon exhibits multiple secondary faults, quick fixes fail. We perform a complete electrical, mechanical, and pressure audit to catch every root cause in a single visit.
