Direct Answer: Cleaning Service
Our cleaning service prioritises air-conditioner cleaning, with post-renovation formaldehyde removal and deep disinfection. After renovation, whole-home cleaning should come before formaldehyde treatment for better results.
Key service points
Professional cleaning for window units, split units, cassette/ceiling-concealed units, outdoor units and central AC.
Testing, decomposition treatment and follow-up advice for newly renovated units.
For homes, offices, schools and institutions, covering touchpoints, space disinfection and long-lasting coatings.
Emphasis on eco-friendly, low-harm solutions safer for children and pets.
Whole-home cleaning should come before formaldehyde treatment to avoid dust affecting coating performance.
AC cleaning can include maintenance or review arrangements by plan; other services can include follow-up.

Post-renovation formaldehyde removal
Formaldehyde is a common indoor air pollutant from building materials and new furniture. Release is highest in the first months but can continue for years.
Common formaldehyde sources
- Plywood, wood products and panels
- Flooring, carpets and insulation
- Paints, adhesives and decorative materials
- New furniture and renovation materials
- Tobacco smoke (if present on site)
Health impacts
- Eye, nose and throat irritation
- Long-term exposure may affect respiratory health
- Higher risk for pregnancy, infants and sensitive occupants
- WHO classifies formaldehyde as carcinogenic and teratogenic
We reference indoor air quality guidelines targeting 0.08 ppm (80 ppbv) or below.
Formaldehyde removal process
Record formaldehyde levels in each room, living area, bathroom and kitchen; remeasure at same points after treatment.
Decomposes formaldehyde without light; non-toxic, colourless and odourless.
Catalytic oxidation under light degrades formaldehyde, benzene and other VOCs; also antibacterial.
Used when site is unoccupied; ventilate and confirm safe ozone levels before re-entry.
Before/after readings, photo records and improvement recommendations.
Deep cleaning and disinfection
Professional deep cleaning and disinfection for homes, offices, public/private institutions and schools to improve hygiene and reduce pathogen spread.
For higher hygiene standard environments.
Persistent protection on high-touch surfaces.
Deep cleaning to remove stains and odours.
Comprehensive cleaning of touchpoints and hidden areas.
