General servicing. A general service cleans the filters, front panel and drain line so the unit keeps cooling and stops dripping. 71 companies here list it.
Chemical wash. A chemical wash takes the indoor unit's coil and blower out of the grime that a normal service can't reach, without fully stripping the unit. 69 companies here list it.
Chemical overhaul. An overhaul strips the indoor unit down so the coil, blower and tray can be soaked and scrubbed, and is the deepest clean on offer. 59 companies here list it.
Gas top-up. A gas top-up adds refrigerant when pressure is low. A good technician checks for a leak first, because gas doesn't get used up. 64 companies here list it.
Installation. Installation covers new systems and replacement units, including piping, trunking and the outdoor condenser bracket. 61 companies here list it.
Repair & troubleshooting. Repair work covers units that leak water, blow warm air, trip the breaker or make new noises. 68 companies here list it.
How to pick a company
Start by deciding the job. Routine cleaning is a general service. A unit that smells or blows weakly may need a chemical wash, and one that has gone years without a deep clean may need an overhaul. Then ask two or three companies for written quotes on the same units, and compare what each one includes: the outdoor unit, drain flushing and any warranty.
Be careful with gas top-ups. Refrigerant runs in a sealed loop, so a unit that needs gas usually has a leak. A good technician checks for one first. Our guide on gas top-up signs explains what to ask.
Where the companies are based
The biggest clusters in this directory are in Woodlands, Serangoon, Geylang, Tampines. Each company's area is worked out from its business address and the URA planning area boundaries, not from where it says it works. Smaller planning areas with one or two companies don't have their own page yet, but those companies still show on the near-me map and the A to Z list. Where a company is based says little about where it works, since most send technicians across the island.
Looking after your aircon between visits
Rinsing the filters every few weeks is the easiest thing you can do. On most wall units the front panel lifts up and the filters slide out by hand. Let them dry fully before you put them back. Switch the unit off at the isolator before opening it, and leave the coil, blower and drain line to a technician.
Keep an eye on the outdoor unit too. Leaves, bird nests and items stored on the ledge can block airflow. If it can't release heat, the indoor unit cools less well and works harder. And if you notice water dripping indoors, switch the unit off and book a check. A blocked drain is usually a simple fix, but water can damage walls and furniture if left alone.
What we check, and what we don't
Every company here has a business address confirmed against OneMap and a website we could read that talks about aircon work. We note the services and brands each company names itself. We don't verify licences or the quality of work, and we don't show star ratings or prices. Details change, so confirm with the company before booking. Read more in how we verify.
How this directory works
We started with a list of aircon companies in Singapore, then kept only those with a website we could read or an OpenStreetMap entry. For each one we noted the services and brands the company names itself, and matched its postal code to OneMap for an address and map pin. We don't show star ratings or reviews, and there are no paid rankings.
