Frequently Asked Questions

Common queries and expert answers.

Due to Singapore’s high humidity and constant usage, we recommend a General Service once every 3 months for residential units. For commercial units with heavy daily usage, monthly servicing is often required to maintain peak efficiency.

A General Service is a maintenance clean (filters, panels, vacuuming drainage) to keep a healthy unit running smoothly. A Chemical Wash is a deep-cleaning restoration process using specialized solutions to dissolve stubborn grime, jelly, and mold from the internal coils—recommended if your unit is leaking water or has weak airflow.

Yes! We stand by the quality of our work. AC HUB provides a 90-day workmanship warranty on our servicing and repairs. If the same issue persists within this period, we will return to fix it at no extra cost.

A typical air-conditioner installation usually takes 3 to 6 hours, depending on the setup.

Factors that can affect installation time include the number of indoor units, piping length, mounting location, electrical work, and site conditions.

Absolutely not. We believe in transparent pricing. Our technicians will assess your unit and quote you for the necessary work before starting. You will never be shocked by the bill at the end of a service.
