Most people book the wrong one, either paying for an overhaul when a wash would do, or paying for servicing three times before someone tells them the unit needed a wash. The short version:
Every 3 to 4 months for a unit in daily use. Singapore runs humid all year, so coils stay damp and grow biofilm far faster than in a temperate climate, and a neglected unit loses cooling efficiency long before it actually fails.
If a bedroom unit runs overnight most nights, treat quarterly as the baseline rather than the maximum. Units in rooms that are rarely used can stretch to twice a year.
In rough order of likelihood: a clogged filter or coil restricting airflow, a drainage tray blocked enough to trip the unit, low refrigerant from a leak, or a failing compressor or capacitor.
The first is by far the most common and is fixed by servicing or a chemical wash. The last is a repair, not a service, and we will tell you that rather than sell you a wash that cannot help.
That smell is biological growth on a permanently damp evaporator coil, and it is not something a filter clean reaches. A chemical wash removes it. General servicing usually will not.
If the smell returns within a month or two of a wash, the unit is holding water somewhere it should not, which points at the drainage tray and an overhaul.
On chemical overhaul we are cheaper than the major platforms at every unit count, $150 for one unit against roughly $160 elsewhere. On chemical wash we are level at one unit and better above it.
On plain general servicing we are not the cheapest per unit, and we are not going to pretend otherwise. If your only criterion is the lowest advertised per-unit rate for routine servicing, there are cheaper options in Singapore.
What you get here instead is a price that does not move: no weekend or public holiday surcharge, no card fee, GST already included, and no upsell to an overhaul when a wash is what the unit needs.
Tell Helen how many units you have and what the symptom is, or book on this site. She comes back with real slots and the exact total for your unit count, not a range.
You get a reminder before the visit, the technician's name before they arrive, and a receipt afterwards. Everything stays on WhatsApp.
Our general servicing is $50 for one unit and $88 for four, which works out at $22 a unit. A chemical wash is $80 for one unit and a chemical overhaul is $150. All prices include GST with no surcharges.
Every 3 to 4 months for a unit in daily use. Singapore's humidity keeps coils damp all year, so biofilm builds up much faster than in a dry climate. Units in rarely used rooms can stretch to twice a year.
A chemical wash cleans the coil in place, from $80 a unit. An overhaul dismantles the fan coil, cleans it fully and reassembles it, from $150 a unit. A wash suits a unit with reduced cooling or a smell; an overhaul suits one neglected for years or leaking from a blocked tray.
Most often a clogged filter or coil restricting airflow, which servicing or a chemical wash fixes. It can also be a blocked drainage tray, low refrigerant from a leak, or a failing compressor. The last is a repair rather than a service, and we will say so.
Biological growth on a permanently damp evaporator coil. A chemical wash removes it; general servicing usually will not. If the smell comes back within a month or two, the unit is retaining water and needs an overhaul.
No. Weekends and public holidays cost the same as a weekday, and there is no card or PayNow surcharge. All prices include GST.
Roughly 20 minutes a unit for general servicing, 30 minutes for a chemical wash and about an hour for a chemical overhaul. A four unit general service is normally done inside 90 minutes.
Yes. Window and portable units are priced separately from wall mounted fan coils, so tell Helen what you have and she will quote the exact total rather than a range.
No. Refrigerant is a closed loop, so a unit that repeatedly runs low has a leak. Topping it up again treats the symptom. We would rather find the leak than sell you gas twice.
If you are servicing quarterly anyway, yes. The quarterly plan covers 4 visits from $180 for one unit, which is less than four separate general services.
Someone needs to let the technician in and be available at the end, because you will be asked to confirm the work. Helen arranges access with you beforehand.
Message Helen on WhatsApp with your unit count and the symptom, or book on this page. You get real slots and an exact total before committing.
