Cool Earth Aircon Now Has a Dedicated Serangoon Service, With Published Prices
By Brian 5 min read 
Today we are launching Aircon Servicing Serangoon, a dedicated service for homes and businesses in Serangoon, run by Cool Earth Aircon. It comes with something many people have asked us for: a full, published price list, so you know what a job costs before you even message us.
Here is what the new service is, who runs it, what it costs and where we cover.
Who We Are
Aircon Servicing Serangoon is the Serangoon service of Cool Earth Aircon. I started Cool Earth Aircon in 2007 as a one-man workshop in Simei. Today the company has serviced more than 4,560 units and completes more than 380 jobs a month across Singapore.
To be clear about one thing: our office is still in Simei, at Block 108, Simei Street 1. We do not have a shop or workshop in Serangoon. Our technicians travel to your home or business for every job. What is new is a service, a team focus and a website built around Serangoon’s estates, its housing and the problems we see there most.
Why a Dedicated Serangoon Service
Serangoon is not one type of home. In a single morning our technicians might service an older unit in a 1980s HDB flat in Serangoon Central, a ceiling cassette unit in an office in Serangoon North Industrial Estate, and a whole landed house in Serangoon Garden with eight units on two floors.
Each of those needs something different. Older HDB flats often need chemical overhauls and leak repairs. Landed homes need whole-house visits, where multi-unit rates and contracts make a big difference. Condos around Lorong Chuan mostly run inverter multi-split systems. A dedicated service lets us plan for all of that, and give clear answers for each part of Serangoon.
Our Full Price List
Hidden charges are the most common complaint we hear about aircon contractors. So we publish our prices.
General aircon servicing (per visit, wall-mounted units):
| Units | Price |
|---|---|
| 1 unit | S$50 |
| 2 units | S$55 |
| 3 units | S$70 |
| 4 units | S$85 |
| 5 units | S$100 |
| 6 units | S$115 |
| 7 to 9 units | S$18 per unit |
| 10 or more units | S$16 per unit |
Other services:
| Service | Price |
|---|---|
| Annual maintenance contract | From S$200 a year for 2 units (4 visits) |
| Chemical wash | From S$80 per unit |
| Chemical overhaul | S$130 to S$180 per unit |
| Gas top-up | From S$80 |
| Aircon repair | From S$60 |
| Commercial servicing | Quote-based |
The final price for cleaning and repair depends on the unit type and its condition, and the technician confirms it before any work starts. The full list, with what each service includes, is on our aircon servicing price page.
How every job works
Fixed quote before work starts. No callout fee for Serangoon. Pay after the job. 90-day workmanship warranty: if the same fault returns within 90 days, we fix it at no extra charge.
If you want to know what a good quote should include, and which add-ons to ask any contractor about, read our guide on what a fixed aircon servicing quote should include.
Why We Publish Our Prices
Most people book aircon servicing once every few months, so it is hard to know what a fair price is. That gap is where surprise charges creep in. A transport fee here, a “gas is low” there, and a S$50 service becomes a S$150 bill.
Publishing our prices closes that gap. You can compare us with anyone before you book. You can check that the quote we send matches the list. And our technicians know that the only way to charge more is to show you why and get your yes first.
What Has Not Changed
The way we work has stayed the same since 2007:
- The technician checks the unit and confirms the work before starting.
- Nothing extra is done without your approval.
- You pay after the job, once each unit is tested.
- If the same fault returns within 90 days, we come back and fix it at no extra charge.
Where We Cover
Our Serangoon service covers:
- Serangoon Central and Serangoon North, including Serangoon North Industrial Estate
- Serangoon Garden, including shophouses along Upper Serangoon Road
- Lorong Chuan and Upper Paya Lebar
- Seletar Hills
