QUESTIONS

COS CentreAC service FAQs

What address should be provided for COS Centre air-conditioning enquiries?

COS Centre can be found near 56 Tsun Yip Street. Different phases, blocks or units may use different entrances, and on-site service still requires the actual street number, block and unit. Please provide the full street number, phase, block, floor and shop/unit number of COS Centre, together with the model, quantity and photos of the unit location.

Does COS Centre have a separate estate or building rate for AC cleaning?

No separate pricing for Cos Centre by property name. Please check against the existing model, number of units and the main price list; commercial models, outdoor units, high-level work or additional work require scope confirmation and a quotation first.

If the air conditioner at COS Centre is dripping water or not cooling, should cleaning or inspection come first?

First explain where and when the symptom appears. Dust buildup, poor drainage and component faults are handled differently; if the cause is unclear, inspect first before confirming cleaning or repair, and cleaning does not guarantee the fault will be resolved. If water is near electrical equipment, stop using the relevant equipment first.

How is the on-site inspection fee for COS Centre calculated?

The inspection/call-out fee is HK$500, and it is the same charge, not charged separately twice. If repairs are carried out after the inspection, this HK$500 can be deducted from the repair fee; if no repair is carried out or the quotation is not accepted, HK$500 will be charged.

Does air conditioning repair include a warranty?

Our repair service does not include a warranty, including parts and workmanship. After inspection, we will first explain the fault, the method of handling, the parts needed and the quotation. Work will only begin after confirmation; parts availability is checked according to the actual model.

What information is needed for replacement or new AC installation?

Provide the new and old unit models, indoor and outdoor unit locations, mounting support, piping, drain and power supply positions, and confirm removal of the old unit, transport and any extra works. Running a new power supply from the main switch to beside the unit is not included in basic installation. The general installation warranty is one year and is calculated separately from the manufacturer's warranty for the unit. Building or management requirements are subject to actual confirmation.

Is there a warranty for AC cleaning?

The cleaning service includes a 90-day warranty. The applicable scope and conditions should be checked against the cleaning service terms; for example, in a dripping case, it must first be confirmed whether it was caused by the cleaning. This does not mean all pre-existing faults or leaks are repaired free of charge.
