Local Knowledge

## Multi-Unit Landed Homes and Multi-Split Systems

Seletar Hills is a landed estate, and most homes run many units. Some use separate wall-mounted units in each room. Others use **multi-split systems** (System 3 or System 4), where one outdoor unit serves several indoor units.

This changes the maths. Here is how our multi-unit rates work for a whole-house visit:

| Units | Price per visit |
| --- | --- |
| 6 units | S$115 |
| 7 to 9 units | S$18 per unit |
| 10 or more units | S$16 per unit |

For a house that needs servicing every 3 to 4 months, an **annual maintenance contract** with four visits and priority booking often costs less than booking each visit separately. It also means you never have to remember to book. Repairs and chemical cleaning are quoted separately if a unit needs more than a general service.

## Planning a Whole-House Visit in Seletar Hills

Our technicians travel to Seletar Hills from our office in Simei. We have no shop or workshop in Serangoon. We bring the tools and cleaning gear to your home.

Seletar Hills jobs are almost always **whole-house visits**. When you WhatsApp us, tell us:

1.  How many indoor units you have, and roughly what type (wall-mounted, cassette, ducted)
2.  Where the outdoor units are
3.  Any unit with a problem, such as a leak, a smell or weak cooling

With that, we give you a fixed quote and the technician confirms the expected time. Evening slots until 9pm Monday to Saturday, and Sunday slots until 8pm, suit families who want everyone home. Same-day slots are available, subject to availability.
