Aircond Chemical Wash vs Normal Service vs Chemical Overhaul, What’s the Difference?

Aircond Chemical Wash vs Normal Service vs Chemical Overhaul, What’s the Difference?

Still not sure which aircon service you actually need?

You’re not alone. Most people book a “service” without knowing there are three very different types,  and choosing the wrong one either wastes your money or leaves your aircon just as dirty as before.

Here’s the honest breakdown.

The Short Answer

People often search for “aircon chemical wash vs chemical overhaul” or “chemical wash vs chemical overhaul” without realising there’s actually a third option,   the basic normal service. Here’s how all three compare at a glance:

|| |General (Normal) Service| |Chemical Wash| |Chemical Overhaul|

|---|

Unit dismantled? No No Yes |

Chemicals used? No Yes Yes |

Outdoor unit cleaned? No Yes Yes |

Gas top-up included? No Yes (20 psi) Yes (20 psi) |

Water leak fix included? No Yes Yes |

Warranty None 30-day water leak 30-day water leak |

Time to complete 30–45 min/unit 45–60 min/unit 60–90 min/unit |

Recommended frequency Every 3–6 months Every 1–2 years Every 2–3 years |

Starting price (1 unit) RM 110 RM 149 RM 268 |

Best for Regular upkeep Dirty/smelly units Long-neglected units |

Option 1: General Cleaning, Your Regular Normal Service

Starting from RM 110 for 1 unit (RM 90/unit for 3–4 units)

Think of this as the basic wash your aircon needs every 3–6 months to stay healthy. No chemicals. No dismantling. Fast, clean, and straightforward.

What’s included:

• Air filter cleaning

• Front cover and panel cleaning

• Blower and fan cleaning

• Drainage system check

• Basic performance check

Who needs this: If your aircon is cooling well, doesn’t smell, and you just want to keep it in good shape,  this is the right service. It’s the most affordable option and ideal for units that are serviced regularly.

What it won’t fix: If your aircon smells musty, is leaking water, isn’t cooling properly, or hasn’t been serviced in over a year,  general cleaning alone won’t solve the problem. You’ll need one of the services below.

Note: General cleaning comes with no warranty. It’s a maintenance service, not a repair.

Option 2: Premium Chemical Wash + Water Leak Fix, The Deep Clean

Starting from RM 149 for 1 unit (wall-mounted 1.0–3.0hp)

This is the most popular service for a reason. Chemical wash goes where a regular clean can’t,  flushing out mould, bacteria, calcium buildup, and years of accumulated grime using professional-grade cleaning agents.

Unlike general cleaning, your unit does not need to be dismantled. Our technicians use high-pressure water and chemical solution to flush the evaporator coil, blower, and drainage system,  then test everything before they leave.

What’s included:

• Premium Chemical Cleaning

• Water Leak Repair (Worth RM 130)

• Free Gas Top-Up (Up to 20 PSI)

• Full indoor and outdoor unit wash

• Blower cleaning

• Filter cleaning

• Drain pipe flushing

• Cooling performance check

• Before & after service photos

• Digital service report

• Free transportation, toll, and parking

• 30-day water leaking warranty

• No hidden charges

What's not included: Refrigerant leak repairs, spare parts replacement, damaged drain pipes, drain pump faults, electrical repairs, hacking works, and major repair works. Any additional work is quoted and approved before proceeding.

Chemical Wash Prices

Wall-mounted 1.0hp – 3.0hp (one price list, all HP):

|Units| |Price per unit|

|---|

1 unit RM 149 |

2 units RM 129/unit |

3–4 units RM 119/unit |

5+ units RM 109/unit |

Who needs this:

• Your aircon smells musty or mouldy

• Airflow feels weaker than it used to

• The unit hasn’t been properly serviced in 1–2 years

• You want a thorough clean without the higher cost of overhaul

• Your unit is leaking water

Option 3: Chemical Overhaul, The Full Restoration

Starting from RM 268 for 1 unit (RM 227/unit for 3+ units)

This is the most thorough aircon service available. Everything in the chemical wash,  plus the indoor unit is fully dismantled for cleaning. The blower wheel, evaporator coil, drainage tray, and housing are cleaned individually, then reassembled and tested.

If chemical wash is a deep clean, overhaul is a complete restoration.

What’s included:

• Full indoor unit dismantle

• Chemical cleaning of all internal components (blower, filter, coil flushing)

• Full indoor and outdoor unit wash

• Water leaking fix

• Free gas refill up to 20 psi (1.0–1.5hp; 2.0hp and above: RM 2/psi)

• Free transportation

• 30-day water leaking warranty

Chemical Overhaul Prices

|Units| |Price per unit|

|---|

1 unit RM 268 |

2 units RM 241/unit (10% off) |

3+ units RM 227/unit (15% off) |

Who needs this:

• Your aircon hasn’t been serviced in 2–3 years or more

• Chemical wash has been done but the unit is still not performing well

• There’s visible mould or black deposits on the blower wheel

• You want the most thorough clean possible before a new tenancy or renovation

• Your aircon is still under warranty and you want to keep it in peak condition
