Aircon Water Leak Repair & Diagnosis in Singapore
Is your aircon leaking water, not cooling properly or running low on gas? We diagnose the actual fault before recommending a repair, so you receive a clear explanation and quote before work begins. For water leaking from an indoor aircon unit, our technicians inspect the drain line, drain pan, condensate pump, filter and evaporator coil to identify the cause before repairing it. Our team repairs water leaks, refrigerant gas leaks, drainage problems and damaged aircon piping for homes across Singapore.
What we fix
Common Aircon Repair Problems We Fix in Singapore
Most aircon problems typically develop from noticeable changes in the cooling, drainage or noise level. Firstly, your system will be examined meticulously to locate the reason before our engineers will propose any solution. In the process, we assist customers with Midea, Mitsubishi, Daikin, Panasonic, LG, Hitachi and other big aircon brands for homes.
We fix a lot of aircon systems that are not producing cold airflow, causing water to leak from the indoor unit, not holding the cold air because of refrigerant leaks, producing strange sounds or causing the household's circuit breaker to trip. In addition, we look into damaged, leaking or insufficiently insulated aircon pipelines, especially when there are indications of weak cooling or refrigerant loss.

Aircon Leaking Water? Causes and Repair
If water is leaking from your aircon indoor unit, common causes include a clogged drain line, a dirty filter, a frozen evaporator coil, a badly sloped drainage pipe, a damaged drain pan, a loose drainage connection or a faulty condensate pump.
Water running out of an aircon can also be caused by a broken drain pan, a pipe that's not properly fixed to the drain, or a malfunctioning condensate pump. Left unnoticed, the problem could cause water stains, develop mold, and even damage walls and furniture.
Our first step is to locate the source of the leak, which could be the fan coil, filter, drain line, drain pan, or condensate pump. If we do not detect the problem right away, then we will proceed by cleaning, fixing or replacing the part that is affected before carrying out a complete drain test. If water is dripping close to a plug, wall socket, or electrical part, then turn the system off and get in touch with our team so that they can carry out an inspection on it.

Gas & refrigerant
Aircon Gas Top Up, Refill and Gas Leak Repair
Aircon refrigerant, commonly known as aircon gas or Freon, is not used up during normal operation. If your aircon is running low on gas, there is usually a refrigerant leak at a piping joint, flare connection, valve or copper pipe coil. Weak cooling, frost or ice on the piping or indoor unit, a hissing sound and higher electricity bills can all indicate a possible gas leak.
We first assess the refrigerant pressure and locate the source of the leak. We carry out the required gas leak repair before we top up or refill the aircon gas according to your aircon model and refrigerant type. Refilling gas without repairing the leak may only provide a temporary solution. Our aircon gas top-up price depends on the refrigerant type, the amount required and whether repair work is needed, and we provide a clear quote before we begin.
Piping
Aircon Piping Repair and Replacement
Aircon piping carries refrigerant between the indoor fan coil and outdoor condenser. Damaged, corroded, kinked or poorly insulated piping can lead to refrigerant leaks, ice on the pipes, water dripping from the indoor unit and weak cooling performance. These issues may occur at copper pipes, flare connections, insulation or joints, especially in older systems or after renovation work.
We inspect the aircon piping, insulation and connections to identify the affected area. Where needed, we repair or replace damaged sections, pressure-test and vacuum the system, then verify cooling performance after the refrigerant has been refilled. For new systems or renovation work, we can also provide aircon piping installation as part of our installation service.

Signs Your Aircon Needs Repair Now
Early repair can prevent a small drainage, cooling or refrigerant issue from becoming a more costly breakdown. Contact us for an inspection if your aircon takes longer to cool the room, leaks water, develops frost or ice, makes a hissing sound or causes a sudden increase in electricity use.
We recommend switching the unit off and contacting us promptly if water reaches an electrical outlet or if the circuit breaker trips. We will assess the fault, explain the repair required and provide a quote before proceeding.
Why choose us
Why Homeowners Choose Us
We believe a proper diagnosis is the most important part of aircon repair. Our technicians explain the issue clearly, recommend only the work your system needs and provide transparent pricing before we begin. We use suitable genuine or compatible replacement parts where required and support major residential aircon brands.
After the repair, we test cooling performance, drainage and the affected component before we leave. We also provide service warranty support for completed repair work. Same-day or next-day slots may be available, subject to technician availability.
On the visit
What's Included
When you book an aircon repair visit with us, we start by inspecting the problem and checking the relevant components. Depending on the fault, this may include refrigerant pressure, leak points, drainage, aircon piping, electrical parts, cooling performance, the capacitor, PCB or compressor.
We provide a clear quotation before repair work starts. Once you approve the repair, we carry out the appropriate work for your aircon brand and model, then test the system before we leave to confirm that cooling and drainage are operating properly.
How fast can you attend to a breakdown?+
Most requests are attended to within 24–48 hours, with priority slots for urgent cases.
Do you charge a callout fee even if I don't proceed with repair?+
A standard diagnosis fee applies for the visit; it's communicated upfront and offset if you proceed with the repair.
Is my aircon still under warranty?+
If your unit is within the manufacturer's warranty period, let us know — we'll advise whether repair should go through the original installer or brand service centre instead.
Why is my aircon leaking water?+
Aircon water leaks are commonly caused by a blocked drain line, dirty filter, frozen coil, damaged drain pan or poor drainage slope. We inspect the indoor unit and drainage system to identify and repair the cause.
Can I still use my aircon if it is leaking water?+
You should switch the aircon off if water is dripping near a power socket, electrical component or the circuit breaker. For other leaks, avoid running the unit for long periods and book an inspection, because continued leakage can damage walls, flooring or nearby furnishings.
How much does aircon gas top-up cost in Singapore?+
The cost depends on the refrigerant type, the amount required and whether a gas leak must be repaired first. We inspect the system and provide a clear quote before we begin any gas top-up or refill work.
How much does aircon water leak repair cost in Singapore?+
The cost depends on the cause of the leak and whether cleaning, part repair or part replacement is required. We inspect the indoor unit and drainage system first, then provide a clear quotation before any repair work begins.
Do I need an aircon gas top-up every year?+
No. Aircon refrigerant is not consumed during normal operation. If the gas level is low, there is usually a leak, so we identify and repair the source before we refill the refrigerant.
