Drip. Drip. Drip.
There’s an incessant drip coming from somewhere in the house and you can’t find it.
Drip. Drip. Drip. There is goes again!
You follow the source of the sounds to find a neat little puddle under your air conditioner on your brand new carpeting. Ah ha! You finally located the source of the dripping and low and behold you realize, “my AC’s leaking water!”
While this is nothing to panic about, it is something that needs to be addressed. We take a look at t the possible reasons as to why your air conditioner is leaking water inside your house and what you can do to fix it.
Clogged Condensate Drain
The most common cause of your air conditioner leaking water is due to a clogged up condensate line. This part of the air conditioner is responsible for draining the condensation from the overflow pan into a drainpipe or outdoors, and not in your home.
Unfortunately, over time this drain line can get clogged with dirt, dust or mold, which means that the water gets backed up and floods the overflow pan. If the drain line isn’t cleaned regularly, algae and mold can grow inside the drain, causing blockage, musty smell, and water leaking.
The solution? Yup, you guessed in – unclog the condensate drain. This can generally be done by vacuuming the drain line with your hoover or using some surgical tubing to free the blockage. If this doesn’t do the trick you may have to call in the services of a professional AC technician to do the job properly.
A clogged condensate drain can be avoided altogether through regular cleaning. A great way to prevent a build-up of algae and bacteria is to pour some chlorine bleach down the drain every four to six months.
Clogged Air Filter
Another part of your AC system that, when blocked, can lead to your air conditioner leaking water is the air filter. When the air filter is dirty and clogged, it causes a build-up of ice on the AC’s evaporator coils.
When this ice melts, it drips an excess amount of water into your overflow pan. And that causes water leakage inside your house.
To avoid this problem, your air filter needs to be changed on a regular basis. Continuously check it to see if it’s dirty and if it needs changing, but this should be approximately every one to three months, depending on the season.
Damaged Overflow Pan
As you may have noticed, the overflow pan plays a crucial role in making sure your air conditioner doesn’t leak any water inside your house. It’s the metal part of the AC that catches any condensation.
If it overflows, it causes water leakage, but another reason could be because of a faulty overflow pan itself.
If your overflow pan is damaged or seriously rusted, water could be simply falling right through the pan, defeating its whole purpose. To check for this, use a flashlight to check for any holes.
Look along the edges of the pan, as well as the specific spot where the water is leaking through.
You could try to patch up small holes or cracks with an epoxy adhesive, but your best bet would be to simply replace the whole overflow pan. Rather safe than sorry.
Broken Condensate Pump
The condensate pump is responsible for pumping and lifting water from the overflow pan to outside of your home. If it is broken, has a hole or a leak, it could be the reason for water leaking inside your house.
To test if the condensate pump is faulty, pour water into the overflow pan and see if the excess water is being pumped out correctly. If it isn’t, the next step is to check to see if the pump is getting enough power. If it is, it is either the motor or the condenser that is causing the problem.
A professional should be contacted in order to confirm which one it is and fix it.
AC can be complex systems to install. If the specific air conditioner brand isn’t installed exactly as it should be or is not the right fit for your home, it could cause some serious problems, including water leakages.
A common problem with installation is if the AC unit is installed skew and is not level, which can cause water leakages. Another possibility is a build up of pressure due to closed vents which were not spotted during an incorrect installation.
The best way to combat this problem is to ensure your AC is installed by a professional AC services company, with experience installing your specific AC brand and model.
Cold Temperatures Outside
When the temperatures outside your house are low, less water is evaporated. That can cause a buildup of water inside the AC unit, which results in your air conditioner leaking water.
Another possibility is when the outside temperature is below 60 degrees. In this case, if you are still trying to cool your home at such low temperatures, the AC coils are likely to freeze up, causing water leakage.
Low Refrigerant Level
When the refrigerant level of your AC is too low, your AC unit loses pressure. This leads to the evaporator coils freezing over, and when those melt, it can cause an overflow of water in the overflow pan. And we know how that can cause your air conditioner to leak water.
Fix Your AC’s Leaking Water
