Genuine Component Replacement • Makati & Taguig
Expert Aircon Unit Parts Replacement in Makati & Taguig
When a single internal component fails, your entire aircon unit stops working — but that doesn’t mean you need to buy an expensive new aircon.
Sterling Air pinpoint-diagnoses broken parts, sources factory-matched OEM components for all major brands, and executes precise on-site replacements across Makati, BGC, and Taguig.
Component Failure Diagnostics
Don’t replace the entire unit for a single failed part. Match your symptom below.
Unit Runs But Gives Zero Cooling
The compressor’s internal electrical windings or valves may have failed. We perform winding resistance tests before recommending a matched compressor replacement.
Clicking Sounds & Motor Stalling
A weakened starting capacitor prevents the compressor or fan motor from kicking in. We test microfarad ratings and swap blown capacitors on the spot.
Error Codes & Remote Unresponsiveness
Voltage spikes or moisture cause PCB control board failures. We test circuit traces to repair or swap damaged microprocessor PCB modules.
Weak Airflow or Screeching Sounds
Dry bearings or burnt motor windings impair fan blades. We replace indoor blower motors or outdoor condenser motors with exact RPM spec matches.
Water Pooling Under Indoor Unit
In high-rise condos, automatic condensate drain pumps fail over time. We replace faulty pumps to ensure continuous drainage lift out of your property.
Cycles On & Off Erratically
Damaged temperature sensors misread room heat, shutting off early or overworking the motor. We replace NTC thermistor sensors for accurate thermostat tracking.
Factory Specification Matching
9 Core AC Component Replacement Capabilities
We carry common high-failure parts directly in our service vans for fast, single-visit component replacements across Makati and Taguig.
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 • MOTORS
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 03 • 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 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 • DRAINAGE
Automatic Drain Pump Replacement
Water pooling inside the unit or leaking to your ceiling? A failed drain pump cannot move water out. We replace faulty pumps, clear lines, and confirm proper drainage flow.
STEP 06 • SENSORS
Thermostat & NTC Sensor Calibration
Wrong temperature readings or erratic cycling indicate a faulty sensor. We test thermistor resistance levels and replace faulty sensors during the same visit.
STEP 07 • VALVES
Thermal Expansion Valve (TXV) Fix
Coil icing and pressure problems stem from a jammed expansion valve. We install the correct replacement valve, recharge to specification, and restore Freon flow.
STEP 08 • EVAPORATOR
Indoor Evaporator Coil Replacement
Corroded or leaking evaporator coils cannot absorb heat. We replace indoor coils with brand-matched aluminum or copper units and pressure-test for zero leaks.
STEP 09 • CONDENSER
Outdoor Condenser Coil Replacement
Overheating outdoor units caused by severely damaged condenser fins require full coil replacement. We swap coils, pressure-test, and verify powerful heat release.
