Specialized AC Maintenance • Makati & Taguig
Hospital-Grade AC Unit Maintenance & System Reset
Is your split-type blowing warm air in 35°C heat, dripping water on your hardwood floor, or tripping your circuit breaker? Sterling Air provides rapid, root-cause component diagnostics and repair across Makati, BGC, and Taguig. No guesswork. No temporary patches. Just durable engineering that holds.
Is Your Aircon Warning You?
If you say “YES” to even one of these signs, your unit requires a technical deep maintenance reset — not a basic filter rinse.
Running All Day, Still Lukewarm?
Unit works continuously without reaching thermostat temperature.
Rising Monthly Electric Bills?
Clogged coils force the motor to draw double the electricity.
Musty or Moldy Odor?
Fungus and bacteria breeding in clogged evaporator coils.
Water Leaking On Wall / Floor?
Algae and drain pan sludge causing overflow damage.
Over 12 Months Without Cleaning?
Overdue maintenance leads to sudden compressor failure.
Rattling or Humming Noises?
Dirty blower wheels creating mechanical motor imbalance.
Full System Sanitation & Technical Calibration
Our 9-Point Deep Maintenance Protocol
Unlike quick surface cleaners who just wash your plastic grilles, every Sterling Air maintenance visit follows an exact technical workflow across Makati and Taguig.
STEP 01 • SANITATION
Deep Chemical Coil Sanitation
We open the indoor unit and flush the evaporator coil with anti-bacterial solution using high-pressure hydro-jets, removing hidden mold, grease, and dust.
STEP 02 • DRAINAGE
Drain Line Hydro-Jet Clearing
We flush and vacuum the drain pan and drainage line, completely removing algae and sludge to prevent catastrophic water damage to your ceilings or walls.
STEP 03 • REFRIGERANT
Freon & Pressure Audit
We connect manifold gauges to test R22, R410A, or R32 operating pressures. If refrigerant is low, we inspect for copper pipe leaks before refilling.
STEP 04 • ELECTRICAL
Capacitor & PCB Ampere Test
We test electrical capacitors, contactors, and control board connections under full operating load to flag weak electrical components before they burn out.
STEP 05 • AIRFLOW
Blower Wheel De-Molding
We deep-wash the indoor blower wheel and balance fan blades to eliminate rattling sounds and restore maximum cubic-feet-per-minute (CFM) air velocity.
STEP 06 • OUTDOOR UNIT
Condenser Coil Pressure Wash
The outdoor unit bears Manila’s road dust and humidity. We hydro-jet the outdoor heat exchanger coil to allow proper heat release and lower power draw.
STEP 07 • DISINFECTION
Anti-Bacterial Grille Treatment
Filters and outer casings are disinfected with hospital-grade sanitizing solution to ensure clean, odor-free air quality for your family or office staff.
STEP 08 • MECHANICAL
Motor Bearing & Noise Inspection
We inspect indoor and outdoor fan motors, checking for shaft play, dry bearings, or unusual vibration before mechanical failure occurs.
STEP 09 • QUALITY ASSURANCE
30-Minute Stress Test & Sign-off
Before leaving, we run your unit at maximum cooling for 30 minutes, measuring temperature differential output and confirming zero water leaks.
