Air conditioner leaking water is a common issue during Sydney summers. It can be alarming to find a puddle of water next to the evaporator (indoor unit) and around the compressor (outer unit). It is a confusing issue because there can be multiple causes for this problem. Oftentimes, your air conditioner’s dehumidifying process causes some condensation but there are various other factors to consider.
One thing you can be sure that if your AC is leaking water, it means your system is not working as efficiently as it should. You might be able to find the source of the leak after running few tests by yourself but it is recommended to consult an air conditioning system expert to help you fix the issue correctly.
Here are few factors for your air conditioner causing water leakage problem. These causes may help access the issue and help run your air conditioner more efficiently.
Clogged condensate drain line
If the condensate drain line is clogged with sludge, dirt or dust, it can cause water backing up into your home. This is one of the most common causes of water leaking from your air conditioner system. To unclog the condensate drain, various methods are available; for example, a dry/wet vac is usually used to suck the dirt out. However, having an expert air conditioner repair or maintenance service Sydney help you access and resolve the issue in a better way.
Broken condensate pump
If the condensate pump is broken, the water will not be pumped outside. So, you will need the pump repaired or replaced. To access this issue, consulting a professional will be required to help properly check the power to the pump, the condition of the motor as well as the condenser itself.
Rusted/damaged drain pan
If your AC leaks water, the drain pan might have been badly rusted or damaged. It mostly occurs when you have got an old system. So, replacing the pan may help stop the water leakage. And if your AC is 10-15 years old then you might consider replacing a whole new efficient unit.
Dirty air filter
If the airflow is blocked due to dirty air filter, the evaporator coil can get frozen, which when melted releases extra amount of water that may overflow the pan. So, make sure your air filter is clean and it is also crucial to get new filter for every 1 to 3 months depending on the season.
If you are low on refrigerant, your air conditioner will have lower pressure, resulting the evaporator coil to get frozen and when it is melted, the drain pan may not be able to handle the excess water. You may have low on refrigerant if your system is not cooling properly or if you keep hearing the bubbling and hissing noise. To resolve this problem you will have to hire a professional air conditioner service in Sydney to help you determine whether you need to re-charge the refrigerant or replace the entire air conditioning unit.
