Commercial Aircon Servicing in Serangoon
Ever had your aircon give up at 2pm, just as the shop fills up? It happens more often than you’d think, and it is almost always avoidable.
Brian started Cool Earth Aircon in 2007 as a one-man workshop, and Aircon Servicing Serangoon is our local team. We do commercial aircon servicing for small offices, shops and eateries on a fixed schedule. Every visit is planned around your opening hours, so your staff and customers barely notice us.
Here are the units we cover:
- Wall-mounted split units
- Ceiling cassette units
- Concealed ducted units
Why bother with a schedule? Studies reported by The Japan Times put cooling at 40 to 60% of a building’s energy use, so a unit that runs badly costs you every day.
Pricing is quote-based. It depends on the number and type of units and the schedule you choose. Every visit carries our 90-day workmanship warranty, and we keep a job record for each unit.
Business Types We Serve
Offices and light industrial units
Serangoon North Industrial Estate has many light industrial and office units. According to Dollars and Sense, the estate is home to light and clean industries such as precision engineering, electronics, logistics and warehousing.
Many of these units run ceiling cassette and ducted systems for long hours, and dust from work areas clogs filters quickly. We usually recommend servicing every 3 months, with visits before staff arrive or at weekends. That sits within the one to three month range that Singapore contractor MET gives for most commercial buildings.
Shophouse eateries
Around Serangoon Garden Circus, a roundabout bordered by eateries, and along Upper Serangoon Road, shophouse eateries face a special problem: kitchen grease. Grease in the air sticks to filters and coils and traps dust, so units clog much faster than in homes.
Servicing every 2 to 3 months keeps the dining area cool and stops grease-laden drips. Some Singapore contractors, such as Airple, suggest monthly visits for very oily kitchens. If you run a wok-heavy kitchen, tell us, and we will check the coil condition on the first visit and adjust the gap.
Small retail shops
Small shops need steady cooling for customers all day. A fixed schedule prevents the mid-afternoon breakdown that empties a shop.
Cost matters too. Singapore servicing firm NewCool says dirty filters and coils can push energy use up by 10 to 30%, which is a lot on a unit that runs from opening to closing.
Unit Types We Service
| Unit type | Where you find it | What we pay attention to |
|---|---|---|
| Wall-mounted split | Offices, shops, eateries | Filters, coil, drain line |
| Ceiling cassette | Offices, shophouses, shops | Drain pump, drain tray, 4-way louvres |
| Concealed ducted | Offices, larger shophouses | Ceiling access panel, filters, fan coil unit |
Cassette and ducted units need a ladder and ceiling access. Tell us about access when you book, and we plan the visit time to suit.
A clear ceiling panel saves time. Technicians reach the drain pan and condensate pump from above, as Singapore contractor SACES points out in its 2026 guide to cassette cleaning.
How the Servicing Schedule Works
- You send your unit list, address and opening hours.
- We check the site and agree a fixed quote and a servicing schedule.
- We remind you before each visit and turn up as planned.
- Each unit is serviced, tested and logged.
We set the gap between visits by how hard your units work, not by a calendar date. MET makes the same point: the right frequency follows the actual load on the system.
If a unit needs more than a service, such as a chemical wash for weak cooling or a repair, we quote it first and wait for your approval.
Common Problems We Solve for Businesses
Leaking cassette units
A failed drain pump or choked tray drips water from the ceiling onto desks or customers. SACES notes that a jammed float switch or a seized pump motor is behind most cassette leaks, and the water can stain ceiling tiles brown over time. We check the pump and clear the drain.
Standing water also carries a legal risk. NEA’s 2025 Code of Practice on Environmental Health says premises owners can be penalised under the Control of Vectors and Pesticides Act when trays create conditions for mosquito breeding.
Grease-clogged eatery units
Grease and dust form a sticky layer on filters and coils. Regular servicing, with a chemical wash when needed, keeps airflow steady.
Uneven cooling across an office
One cold zone and one warm zone often comes from a dirty indoor unit or a blocked ducted filter. A proper service usually evens it out.
Filters are worth watching. Singapore firm Prima Services says dirty filters alone can raise energy use by 5 to 15 percent, because the fan has to push air through the clog.
