FAQ

Frequently asked questions

What you most want to know about on-site service in Xuhui

Do you fix desktops on-site or must I bring it in?

Most faults can be fixed on-site — our technician brings tools and common parts. If specialist equipment is needed, we'll explain and agree on a time.

Do I pay if it can't be fixed?

On-site diagnosis is free. We give you a quote after diagnosis and only start once you confirm; if it can't be fixed for technical reasons, there's no charge.

How much is cleaning and how often?

Dust cleaning is generally RMB 80–150, including internal cleaning, fan cleaning and thermal paste. Recommended yearly, ideally before summer.

Is an old machine worth upgrading?

Most of the time, yes. Adding RAM or an SSD is the cheapest speed boost — install is usually RMB 50–100, parts can be sourced or brought by you, and done on the spot.

Will my data be lost during repair?

For anything involving storage, we back up or image it first. For recovery, we assess the success rate and confirm the cost before starting.

How long does a visit take?

As fast as 30 minutes if close and traffic is light; most jobs scheduled the same day.
