Our Periodic Maintenance Checklist
Each service visit is conducted according to manufacturer checklist standards, ranging from physical deep-cleaning to electrical audits and performance testing.
Filter & Indoor Cover Cleaning
Removal, washing, and sanitizing of indoor air filters and unit casings for clean air circulation.
Evaporator Coil Jet-Wash
Controlled high-pressure wash of evaporator fins using protective wash bags and safe cleaning agents.
Drainage Line Flushing
Flushing of drain pans and discharge piping to eliminate slime buildup and prevent ceiling water leaks.
Outdoor Condenser Jet-Wash
Pressure washing of outdoor condenser coils to ensure efficient heat dissipation for the compressor.
Refrigerant & Electrical Check
Measurement of refrigerant operating pressure and compressor running amperage using digital gauges.
Delta T Testing & Handover
Testing temperature drop across supply and return air, followed by formal handover of service records.
Why Regular Maintenance Matters
Micro-dust accumulation on cooling coils reduces heat exchange efficiency by up to 25% and strains the compressor. Regular servicing keeps indoor air healthy and energy bills under control.
Efficiency Fact
Servicing every 3 months restores cooling performance by up to 99%, cuts electricity consumption by 20–30%, and extends equipment service life.
Zero Mess, Protected Work Area
Our technicians always use waterproof wash bags and floor drop-cloths to keep your room spotless and dry.
Energy Efficiency, Air Hygiene, and Unit Longevity
Three tangible benefits delivered by the preventive maintenance program of PT IMM.
Save 20–30% on Electricity
Clean evaporator and condenser coils optimize heat exchange, reduce compressor workload, and directly lower monthly electricity bills.
- Maximum coil heat exchange restored
- Compressor runs at optimal amperage
- Reduces monthly electrical expenses
Clean Air & Allergen-Free
Eliminates mould, bacteria, slime, and musty odours inside the AC unit, ensuring the air your family or workforce breathes is always fresh.
- Sanitizes dirt and evaporator mould
- Eliminates musty odours and stale dust
- Fresh, breathable indoor air
Extended Equipment Lifespan
Early detection of potential issues such as minor leaks, weak capacitors, or blocked drains before they develop into expensive major breakdowns.
- Prevents compressor overheating and seizure
- Avoids water leaks that damage ceilings
- Documented digital service history
