## Aircon Services in Serangoon Central

Most homes around Serangoon Central are 1980s HDB flats with two to four wall-mounted units. Many of these units and their pipes are old, so we often see choked drain lines, sludge-filled drain pans and mould that a simple service cannot shift. That is why chemical overhauls and water leak repairs are among our most common jobs here. Evening and Sunday slots suit working households near Serangoon MRT and NEX.

Local Knowledge

## What We See in 1980s Serangoon Central Flats

Serangoon Central is mostly **1980s HDB flats**. A typical flat runs two to four **wall-mounted split units**, often a mix of an older living room unit and newer bedroom units. Three problems come up again and again in these homes:

-   **Choked drain lines.** Older piping and long runs through trunking collect sludge. The first sign is usually a drip onto the wall or bed, often at night.
-   **Heavy mould in older units.** Units that have run for years with only basic servicing build up black mould on the blower wheel and coil. A normal service cannot reach it. That is when a **chemical overhaul** makes sense.
-   **Weak cooling in the living room.** Large open living areas with one unit work hard all day. Dirty coils and filters show up here first.

Because of this, chemical overhauls (S$130-S$180 per unit) and water leak repairs (from S$60) are among our most common jobs in Serangoon Central. We always check first and explain what we found before quoting.

Got Questions?

## Aircon Servicing in Serangoon Central: FAQs

### Do you do chemical overhauls for old units in Serangoon Central HDB flats?

Yes. Overhauls are one of our most common jobs here because many 1980s flats run older units. A chemical overhaul costs S$130-S$180 per unit, fixed before work starts, and carries a 90-day workmanship warranty.

### My bedroom aircon near Serangoon Avenue 3 keeps leaking. Can you help?

Yes. Older piping makes leaks common in these blocks. Switch the unit off and catch the drips. Repairs start from S$60, and if the same leak returns within 90 days we come back and fix it at no extra charge.

### How much is general servicing for a 3-room or 4-room flat in Serangoon Central?

It depends on the number of units, not the flat size. Most flats here have 2 to 4 units: S$55 for 2 units, S$70 for 3 and S$85 for 4. There is no callout fee.

### Can you come on the same day to Serangoon Central?

Often, yes. We keep same-day slots for Serangoon, subject to availability. WhatsApp +65 9427 3833 with your block number and the problem for the fastest reply.

### Do you have an office in Serangoon Central?

No. Our office is at Block 108, Simei Street 1. Aircon Servicing Serangoon is the Serangoon service of Cool Earth Aircon, and our technicians travel to your flat for every job.

Yes. We work until 9pm Monday to Saturday and until 8pm on Sunday. Evening slots go fast, so book a few days ahead if you can.

### Should I get a chemical wash or an overhaul for an old living room unit?

If the unit still cools but feels weak or smells a little musty, a chemical wash (from S$80) is usually enough. If it smells sour, blows black specks or has jelly-like sludge, an overhaul is the better fix. The technician checks first and explains the choice.
