As part of preventive maintenance, we carry out periodic servicing of Air conditioning Units.
Air conditioners usually have a warrant period of 12 months after installation.

During warranty period, we provide a free maintenance service (No charge) for the first three months and our arrival Time does not exceed three hours after call time within the city limits.


We encourage clients to enter maintenance Contracts. This can take form for Annual General service of the Air conditioning systems for better performance and longer life but we can still arrange for Quarterly or Semi – Annually servicing.

We stock common spares for the Air conditioning Units in order to tackle any reported failure within 48 hours.

APC UPS systems

The APC RS 650 Back-UPS RS 900VA

Pros: Voltage regulation and battery backup sufficient for many office workstations.
Cons: A heavyweight for its size at 20.5 lbs. Mine is beige.
Recently I purchased two new APC Back-UPS – the BR750 and the BR800. I purchased them a little late for two of my computers as a severe lightening storm removed three of my four computers from service. Surge protection at the outlets was working before.

More Information
Smart-UPS protects your data by supplying network-grade battery backup when power fails. With Power Chute plus software the uninterruptible power supply (UPS) will safely store data and shut down your network operating system before the battery is fully discharged, whether you’re there or not. Smart Slot internal accessory slot allows you to install optional accessories to enhance the performance of your UPS. APC Smart-UPS is the perfect UPS for fileservers, minicomputers, UNIX CPUs, Internet hubs, telecommunications systems and other mission-critical applications.
