Woke up to a wet patch on the bed, or a steady drip on the floor? It’s stressful, but it’s usually a quick fix. We’re Aircon Servicing Ang Mo Kio, the local service of Cool Earth Aircon, which Brian started in 2007 as a one-man workshop. Aircon water leak repair is one of the jobs our team gets called out for most in the estate. Here’s the thing: every aircon makes water. As warm, humid air passes over the cold coil, moisture condenses and drips into the drain pan, then runs out through the condensate drain line. A leak means that water has found another way out. In most homes, the cause is one of these: - A **choked drain line**, where dust and slime block the pipe so water backs up - A **drain pan** that is cracked, tilted or full of sludge - Worn **pipe insulation** on the copper piping, so cold pipes sweat onto the wall - An indoor unit that is not level, so water tips forward instead of draining Singapore’s weather makes the first one worse. Gree’s Singapore aircon guide explains that year-round humidity lets dust and moisture combine into a slimy biofilm, which narrows the drain pipe until water backs up and spills from the front of the unit. Age matters too. According to a Remember Singapore history of the town, the first flats in Ang Mo Kio were completed in 1973. In the older HDB blocks, ageing piping makes leak repairs a common job. Our technician finds which cause applies before quoting. That way, the fix stops the leak instead of hiding it for a week. ![Technician clearing a choked aircon drain line with a vacuum pump in an HDB bedroom](/images/content/technician-using-vacuum-pump-to-clear-choked-airco.webp) ## How Is the Leak Fixed? Our technician starts at the fan coil unit and follows the water. The steps run in this order: 1. Check the drain pan for cracks, sludge and level. 2. Test the drain line by running water through it. 3. If the line is choked, pull out the blockage with a vacuum flush. 4. Inspect the pipe insulation and the trunking along the wall, especially on older runs where the insulation has gone brittle. 5. Run water through the system again to prove it drains freely. You pay after the job. If the same leak returns within 90 days, we come back and fix it at no extra charge. Prices depend on the cause. A February 2026 cost guide from Homejourney puts typical leak repairs in Singapore at $50 to $300 per unit, which is why we diagnose first and quote after. ## When Is an Overhaul the Better Fix? Some leaks keep coming back because the drain pan is full of jelly sludge. This is a thick layer of slime and mould that re-chokes the line soon after each flush. Clearing the pipe helps for a while, but the source is still sitting in the pan. In that case, the lasting fix is a chemical overhaul [/chemical-overhaul/ →](/chemical-overhaul/) , where we take the unit apart and soak and scrub the pan. It’s quoted separately, and you decide before any work starts. Is dirt building up but no sludge has set in yet? A chemical wash [/chemical-wash/ →](/chemical-wash/) flushes the drain parts with the unit still on the wall. ## Common Problems We Solve ### Water dripping onto beds and floors This is the most common call. Usually it’s a choked drain line, and we clear it on the spot. While you wait for us: - Switch the unit off. - Put a towel below the drip. - Move bedding and electronics out of the way. ### Water stains on the wall Stains below the unit or along the pipe run often point to worn pipe insulation or a drain connection that has come loose. Left alone, they damage paint and plaster. The usual suspects: - Brittle insulation where the cold copper pipe sweats - A drain connection that has worked loose over the years ### Leak only at night Units run longer and colder overnight, so they produce more water. A drain line that is half blocked copes in the day and overflows at night. A frozen coil can also play a part. Gree’s guide notes that when the ice melts, more water lands in the pan than the drain can clear. ### Leak right after servicing Loosened dirt can settle in the line, or a panel may not be seated properly. If the leak follows our own servicing, the 90-day warranty covers it. ## What Can You Do Before the Technician Arrives? A few quick steps keep the damage small: - Switch the unit off at the remote and at the wall switch, especially if water is near a power point. - Put a towel or a bucket below the drip, and move bedding or electronics out of the way. - Leave the drain pipe and the unit alone. Pulling the pipe or opening the unit yourself can crack the drain pan or loosen a connection. - Take a photo or a short video showing where the water comes out. - Send it on WhatsApp with your Ang Mo Kio address. That last step helps a lot. Our technician can bring the right tools and, where the cause is clear, quote a likely price before the visit. One more tip: empty the bucket once the leak is fixed. The National Environment Agency lists pails and similar containers as places where Aedes mosquitoes can breed, so don’t leave standing water around. ## Older HDB Flats in Ang Mo Kio Many blocks in Teck Ghee, Cheng San, Chong Boon and Kebun Bahru [/areas/teck-ghee-cheng-san/ →](/areas/teck-ghee-cheng-san/) were built in the late 1970s and 1980s, and their drain piping and insulation have aged with them. Repeat leaks are more common in these flats. For that reason, we check the whole drain path, not just the pipe end. To keep drains clear between visits, book general aircon servicing [/ →](/) every 3 to 4 months. Each visit includes a drain line flush. If you run 2 to 4 units, it’s easiest to service them all in one go. For anything else that has gone wrong with your unit, see aircon repair [/repair/ →](/repair/) . Got a drip right now? Send us a photo on WhatsApp, and we’ll sort out your aircon water leak repair fast. Pricing ## How much does water leak repair cost in Ang Mo Kio?

He showed me the sludge in the drain pan." RRavi K.Cheng San FAQ ## Water Leak Repair FAQs ### Why is my aircon leaking water? Water dripping from the indoor unit is usually one of three things. The most common is a choked condensate drain line. Dust, mould and slime build up inside the pipe until water backs up into the drain pan and spills over. The second is the drain pan itself: it can crack, tilt or fill with jelly-like sludge. The third is worn pipe insulation on the copper piping, which lets cold pipes sweat so the water runs down the wall. A unit that is not mounted level can also tip water forward. The technician checks each of these to find the actual source, then gives a fixed quote for the fix before starting. ### How much is aircon water leak repair in Ang Mo Kio? Water leak repair starts from S$60. A choked drain line that only needs clearing sits near that starting price. A drain pan fault or a pipe insulation repair is quoted after the technician sees it. If jelly-like sludge keeps choking the system, the lasting fix may be a chemical overhaul at S$130 to S$180 per unit, which takes the unit apart so the drain pan can be cleaned properly. That is always quoted separately, and you decide before any work starts. There is no callout fee and you pay after the job. If the same leak returns within 90 days, the team comes back and fixes it at no extra charge. ### Is it safe to keep using a leaking aircon? It is best to switch it off. Water can stain walls, soak beds and damage flooring, and if it reaches electrical parts or sockets it becomes a safety risk. Put a towel or bucket under the unit and turn it off at the switch. If you need cooling while waiting, use another room or a fan. A drip can also mean the drain pan is full and about to overflow faster. Send a photo or short video on WhatsApp showing where the water comes from, as that helps the technician bring the right tools. Same-day slots in Ang Mo Kio are available subject to availability, with usual arrival within 90 minutes. ### Why does my aircon only leak at night? Units run longer and colder overnight, so they produce more water. A drain line that is partly choked copes in the day but overflows during long night use. ### Why is my aircon leaking right after servicing? Sometimes loosened dirt settles in the drain line, or the drain pan or front panel was not seated properly. If it happens after our work, it is covered by the 90-day warranty. ### Water is dripping from the outdoor pipe. Is that a problem? Some water at the outdoor end of the drain pipe is normal. Dripping from pipe joints or along the trunking is not, and may mean worn insulation or a loose drain connection. ### Can a chemical wash stop the leak? If dirty drain parts are the cause, yes, since the drain pan and line are flushed. If the pan is cracked or the insulation is worn, a repair is needed instead. ### Why do older HDB flats leak more often? Many blocks in Teck Ghee, Cheng San and Kebun Bahru date from the late 1970s and 1980s, and old drain piping and insulation wear out. Leak repairs are a common job there. ### Do you fix leaks on condo multi-split units? Yes. Each indoor unit has its own drain, so the technician checks the leaking unit and its drain path, whether it is a single split or a System 2, 3 or 4 setup.
