Common Problems

## Aircon Problems in Serangoon Homes? We Fix the Cause

These are the calls we get every week from Serangoon homes. Each one has a clear cause, and most are cheaper to fix early.

### Runs but the room is not cold

Usually a dirty coil, low gas or a failed part. We test before we quote.

Aircon not cold

[/aircon-not-cold-repair/ →](/aircon-not-cold-repair/)

### Water dripping onto the wall or bed

Most leaks are a choked drain line or a dirty drain pan. Switch off and catch the drips.

Water leak repair

[/aircon-water-leak-repair/ →](/aircon-water-leak-repair/)

### Musty or sour smell at start-up

Mould on the coil and blower wheel. A chemical wash or overhaul clears it.

Chemical wash

[/chemical-wash/ →](/chemical-wash/)

### Rattling, buzzing or grinding noise

Each noise points to a different fault, from a loose cover to a worn fan motor.

Noisy aircon repair

[/noisy-aircon-repair/ →](/noisy-aircon-repair/)

### Power bill up, same usage

A clogged coil makes the compressor run longer. Regular servicing helps the unit cycle normally.

Got Questions?

## Aircon Servicing in Serangoon: Your Questions

### How much is aircon servicing in Serangoon?

General servicing costs S$50 for 1 unit, S$55 for 2, S$70 for 3, S$85 for 4, S$100 for 5 and S$115 for 6 units, then S$18 per unit for 7-9 units and S$16 per unit for 10 or more. You get a fixed quote before work starts and there is no callout fee.

### Is there a transport or callout fee for Serangoon?

No. There is no callout fee for Serangoon, including Serangoon Garden, Seletar Hills, Lorong Chuan, Kovan, Bartley and Braddell Heights. The price on your fixed quote is the price you pay.

### Is there a warranty on the work?

Yes. All work carries a 90-day workmanship warranty. If the same fault comes back within 90 days, we return and fix it at no extra charge.

### How often should I service my aircon?

Every 3 to 4 months for units used daily. Singapore is hot and humid all year, so units in Serangoon run almost every day and filters and coils clog quickly.

### Can you come on the same day?

Often, yes. We keep same-day slots in Serangoon, subject to availability. WhatsApp +65 9427 3833 for the fastest reply.

### Do you work on Sundays and evenings?

Yes. We are open Monday to Saturday 9am to 9pm and Sunday 9am to 8pm, so working households can book evening and Sunday slots.

### Do I need a chemical wash or a chemical overhaul?

A chemical wash (from S$80 per unit) suits weak cooling and mild musty smells; the unit stays on the wall. A chemical overhaul (S$130-S$180 per unit) suits heavy mould, strong sour smells, jelly sludge or units unserviced for over a year; the unit is taken apart.

### Do you service my brand?

Yes. Our technicians work on all common brands, including Daikin, Mitsubishi Electric, Panasonic, LG, Fujitsu, Samsung, Toshiba, Hitachi, Sharp and Carrier, both inverter and non-inverter.

### Where are you based?

Our office is at Block 108, Simei Street 1 (Singapore 520108). Aircon Servicing Serangoon is the Serangoon service of Cool Earth Aircon, and our technicians travel to your home or shop in Serangoon.

### Do I need to be at home during the service?

Someone should be home to let the technician in, confirm the work before it starts and check the units after testing. Clear the area under each indoor unit before the visit.

### Still have a question?

Send us a WhatsApp with your units and the problem. We reply with a fixed quote.
