Chemical Wash & Overhaul

Deep Chemical Cleaning & Overhaul

When regular general servicing fails to clear stubborn mold, thick dirt layers, and jelly blockages inside your air conditioning system, a chemical wash or chemical overhaul is the ultimate solution. A chemical overhaul involves completely dismantling the indoor unit from the wall, allowing our technicians to deep-clean every single component with eco-friendly chemical solutions.

This process completely removes stubborn odors, clears deep-seated dirt from the cooling coils, improves cooling performance, and helps save up to 30% on energy bills by reducing strain on the compressor. It is the best way to make an old, smelly air conditioner run like new.

Our Scope of Work

Our chemical overhaul is a meticulous restoration service comprising several key steps:

Completely dismantle the indoor unit from the wall mounting bracket
Soak and wash the cooling coils in a non-corrosive chemical solution
Wash fan blower wheel, drain tray, and outer covers chemically
Flush the drainage pipe with chemical cleaner to dissolve thick blockages
Reassemble, vacuum-test, and check operating pressure levels
Re-commission and test overall cooling and wind speed performance

Frequently Asked Questions

Got questions about chemical cleaning? See our answers below:

  • What is the difference between a chemical wash and a chemical overhaul?
    A chemical wash is performed on the wall by spraying chemical cleaner, whereas a chemical overhaul involves taking the entire unit down and dismantling it to wash every single part, which is much more thorough.
  • How often should my aircon undergo a chemical overhaul?
    We recommend a chemical overhaul once every 1 to 2 years for residential units, or whenever the aircon has low cooling, weak wind flow, or emits a moldy smell that general servicing cannot resolve.
  • Is the chemical solution safe for my aircon and family?
    Yes. We use high-quality, diluted, industrial-grade, non-corrosive chemicals that are thoroughly rinsed out with water. It leaves only fresh, sanitized, and odor-free air.
