Why Does My Aircon Leak

Why Does My Aircon Leak?


An air conditioner is more than just a common household item; it is something that many of us could not live without. This is especially true during the summer months, when the weather may quickly become unbearably hot, and you find yourself spending as much time indoors as possible.

Water leaks from air conditioners are known to be harmful. They cause damage to neighboring furniture, increase the danger of accidents due to slick surfaces, and may even raise your electrical expenses. Because you know why your air conditioner is leaking and how to fix it, you won’t have to waste time figuring out what’s wrong so you can fix your home or business air conditioner right away. Here are some reasons why your air conditioning unit is leaking:


When the air filter becomes clogged, the air movement through the system is slowed. This causes the air to freeze, and when you switch off the air conditioner or reach the ideal air temperature, the ice on the filter begins to melt. The water seeps out and the air conditioner begins to leak.


The condensation pump is a device that is installed beneath the cooling coil. The pump’s job is to drain the water completely so that leaks do not occur. Water dripping indicates that the pump is damaged or malfunctioning due to the collection of dust and filth, which is a clear indicator that the pump is not working correctly. 


Refrigerant coolants assist in cooling and blowing away heated air for your comfort. If there isn’t enough gas, the air conditioner won’t blow cold air, and the air won’t condense on the evaporator coil, causing your air conditioner to leak water. You may also hear a bubbling or hissing sound, indicating that the air conditioning coolant is leaking and that you require quick air conditioning repair. You will just only need an aircon gas refill; but, if you believe that the aircon is leaking refrigerant rather than water, then you must reach out to an expert immediately as this harms not only you but also the environment.


When iron is involved, it rusts as a result of the action of water and air (oxygen). The drain pan rusts fast since it is composed of metal. The unit is prone to getting blocked as a result of persistent rusting in the drain pan, obstructing the flow of water outside. This eventually results in spills and air conditioning leaks.


An air conditioner draws humid, warm air from within and blasts it over frozen pipes. Because the coils are filled with cold refrigerant, they are colder than the air. Moisture vapor in the air condenses on the cool coil and condenses into liquid water. The air conditioner will drip unless the water is properly collected and drained.

Any of these might be the reason why your aircon is leaking. If this happens though, you should not hesitate to call KYC Air Conditioning for repairs and checkups.

Just had my air conditioning installed by KYC and am thoroughly impressed by the company as a whole. From the initial meeting at my house through to commissioning they were all extremely polite, friendly, respectful and above all professional. Chris came to my house and came up with a design that no other companies had thought of which suited my house and needs perfectly, and at a better price than the other quotes I received. They came and completed the job in the specified time, tidied up after themselves and said goodbye with a smile. I can’t recommend this company enough.
