What does commercial aircon servicing cover?
Ever walked into a shop where the aircon has quietly given up? Customers leave, and staff get grumpy fast.
Small offices and shops in Ang Mo Kio need aircon that keeps running through business hours. A warm shop loses customers, and a stuffy office loses a working afternoon. Good commercial aircon servicing stops that before it starts.
We service wall-mounted split units, ceiling cassette units and concealed ducted units on a fixed schedule, timed around your opening hours. Brian started our parent company, Cool Earth Aircon, in 2007 as a one-man workshop, and the same hands-on habits still guide how we work.
Each unit gets the same core work as a home service:
- Air filter cleaning
- A check and clean of the coil in the fan coil unit
- A drain line flush and a drain pan check
- A refrigerant pressure check at the condenser unit
- An electrical check
- An airflow and temperature test before we leave
Clean filters matter more than most people think. Singapore servicing company Prima Services says dirty filters alone can raise energy use by 5 to 15 percent, because the fan has to push air through clogged material.
How is a commercial job priced?
Every job gets a fixed quote based on unit count and type before any work starts. Cassette and ducted units take longer than wall-mounted ones, so we quote them separately.
Here’s what that means for you:
- No callout fee
- A fixed quote before we touch a unit
- You pay after the job

Why do commercial units need more frequent servicing?
Office and shop units often run ten hours a day or more, six or seven days a week. Doors open and close, dust comes in, and filters clog faster than in a bedroom. For comparison, a servicing guide from SACES says the commonly cited interval for home units is about every three months, and a shop that runs all day works its aircon much harder than that.
A unit that is undersized for the room works harder still. So does one whose BTU rating no longer matches a new layout. BTU is simply the cooling power of the unit, and it needs to suit the space.
Temperature settings add to the load. In May 2025, the Singapore Green Building Council and the Ministry of Sustainability and the Environment launched the Go 25 movement, which encourages setting indoor aircon at 25°C or above. A study with Ngee Ann Polytechnic found energy savings of up to 12 percent for each degree raised from 23°C to 25°C in offices, with no reported rise in discomfort. A clean, well-serviced unit reaches that setting far more easily.
Regular servicing keeps cooling steady. It also catches small faults, like a slowly choking drain line, before water drips onto desks or stock.
Ang Mo Kio Industrial Park and Tagore
Ang Mo Kio Industrial Park and Tagore are home to light industrial and office units. Jobs here are usually scheduled servicing of ceiling cassette and concealed ducted units, done around business hours so work on the floor isn’t interrupted.
You’ll often see two patterns in these spaces:
- Several cassettes sharing one room
- A few concealed ducted units serving meeting rooms
Planning the visit ahead means we bring the right access gear and finish within the time you set. Units on factory floors also collect more dust, so a regular schedule matters more here than in most offices. Since dirty filters can push energy use up by 5 to 15 percent, a dusty floor can show up on your electricity bill quickly.
Common Problems We Solve
Water dripping onto desks or stock
A choked drain line or a tilted drain pan in a cassette unit can drip straight onto a desk, shelf or counter. Singapore’s humidity runs at around 80 to 90 percent, according to HomeJourney’s aircon leak guide, so units produce a lot of condensation and the drain has to keep up.
Clearing and testing the drainage is part of every service. If it keeps coming back, our water leak repair team finds the cause.
Weak cooling during busy hours
When a shop is full or an office is at its busiest, a unit with a dirty coil can’t keep up. Servicing restores airflow. A heavily soiled unit may need a chemical wash, which we quote before any work.
Units breaking down at the worst time
Most sudden breakdowns follow months without servicing. A fixed schedule cuts the risk. If a unit does fail, our aircon repair service has same-day slots, subject to availability.
What should you prepare before the visit?
A little planning keeps the job short. Here’s what helps us most:
- A list of units by type and room, with a photo of each type if you can
- The location of your outdoor condenser units, whether on a ledge, a rooftop or a back lane
- How the technician gets to those condensers
- For ceiling cassette and concealed ducted units, the ceiling height and whether there’s an access hatch, so the right ladder comes along
On the day, clear desks or shelves directly under each indoor unit where you can. The technician lays down covers before opening any unit. Even so, moving laptops, documents and fragile stock first is safer.
If your building has a management office that needs to approve contractors, register the visit in advance. That way, no time is lost at the door.
Shops, clinics and small offices across Ang Mo Kio
Beyond the industrial park, we service units in neighbourhood shops, tuition centres, small clinics and offices across Ang Mo Kio and the areas we cover. Most of these run wall-mounted units, sometimes with one cassette in the main room.
If you only have two to four wall-mounted units, the process is the same as our home aircon servicing in Ang Mo Kio and the visit is quick. The same fixed quote, no callout fee and 90-day workmanship warranty apply.
Setting up a schedule
Send us your unit list, unit types and opening hours. You’ll get a fixed quote and a proposed servicing schedule, so commercial aircon servicing fits around your trading hours instead of cutting into them.
For homes with many units, see the annual maintenance contract. Aircon replacement for offices is handled by Cool Earth Aircon at coolearth.com.sg.
