In case you use AC daily to beat the heat, the chances are quite high that the unit may show you some signs of wear and tear. One of the most common issues is the water leakage. If you are also wondering why is my air conditioner leaking water, you should keep in mind that it is a good sign because it indicates that the unit needs overdue servicing. However, some other causes could be there that you should not overlook if water is dripping. To locate the same, explore this detailed guide.

What are the Common Reasons for Water Leaking in the AC?

Whenever you see something like this, you must immediately connect with an expert and schedule the servicing. Besides, it can have different causes i.e. rusted parts, dirty filters, etc. that the water is leaking from your air conditioning unit. Below, we have outlined some of them. Have a look:

Improper Installation

Even though a newly installed unit cannot drip water, if it is doing so, it is all because of the installation that is not done properly. You will be amazed to know that even a small mistake during the AC unit’s installation can result in water seeping from the crevices. Hence, it is recommended to opt for professional installation facilities offered by the retailers. Yes, they will charge some extra bucks but you can save on the expensive repairs, replacements, and even re-installation.

Dirty Filters

Well! It is no surprise that every AC unit starts showing issues when the air filters are not cleaned. It is obvious that over time, debris and dust can easily build up on the filters. This will block the airflow and result in extra pressure while providing cool air. This will eventually make the evaporation process difficult which will sooner or later turn into the reason why do AC units leak water. Thus, you can always check the air filters first to see if it is the reason behind the water dripping or if you need something else.

Fungus or Mould

You may or may not know but AC offers the most suited breeding ground for fungus and mould. This is because of the moisture. When the airflow or water is hindered by mildew and other bacterial build-ups, the water inside the unit will start searching for other outlets to go out. Ultimately, it will discharge from unexpected areas and cause leakage. Regular AC maintenance is essential to prevent such issues and ensure the AC functions properly. Apart from this, you can also have health issues because of fungus and mould. They are so harmful that you can have respiratory issues such as asthma and bronchitis when not cleaned.

Rusty Drain Pan

This drain pan is situated under the AC’s evaporator coils. It collects the wastewater before throwing it out. However, the water that is collected in it will start leaking if this pain is rusted or damaged. A rusted pan does not occur overnight. Instead, it is a sign that your AC unit is ageing. Thankfully, you can eliminate the issue and expand the lifespan by keeping the pan clean and doing timely servicing.

Condensation Accumulation

Although condensation is just a normal thing with the functions associated with an AC unit, excess condensation is among the reasons why air conditioner leaking water. With condensation, a dehumidifying process takes place but when it starts in excess, you will notice water dripping. Speaking about the reasons for excess condensation, clogged ducts and high humidity are the main culprits. To fix this issue, you will need to do the ductwork so that insulation can accurately take place.

Disconnected Drain Lines

You must know that the primary function of the drain pipelines is to eliminate the wastewater that is gathered in the drain pan. When there is a malfunction in the connection of these two, you will see some water seeping into the indoor unit. However, you should not fret by seeing this issue as it is easy to fix. All you need to do is – just call an expert who can clean the blockage or mitigate any disconnection between the drain pipe and pan.

Leakage in the Refrigerant

In some cases, the AC unit is not the element that is leaking the water but the refrigerant is the one that is showing the sign of water dripping. This tell-tale water leakage sign can be combined with warm air. In case you are wondering what is refrigerant, it is nothing but a liquid substance that is used to convert warm air into cold one. In case your AC is leaking and the air is not as cool as it is anticipated, it is best to schedule a technician’s visit to get these issues fixed.

To Sum It Up!

You must keep in mind that AC is one of the most complex appliances. Hence, it is not suggested to troubleshoot any issue that occurs. Instead, you must conduct regular servicing, cleaning, and thorough checks to ensure longevity and performance.
