4 Reasons Your AC is Leaking Water Inside Your House

Have you noticed water inside your house? This is annoying and alarming because this can do damage to your home. One of the things that you need to check when you find water leaking inside your property is your air conditioner. When your AC is leaking water inside, it’s crucial you act fast to prevent water damage and costly repairs. 

The question is, what are the reasons your AC is leaking water?

Problems with the Drain Line

The most common cause of AC leaks is when there’s a problem with the condensate drain line. See, your AC unit cools by removing water vapor from the air. This water vapor condenses into water and collects on the evaporator coil that flows down through the drain line. 

If the drain line is clogged with dirt and debris, the backup can cause leaks, or worse, it can rupture the line.

Another issue with the drain line may be due to improper installation. When this happens, make sure you hire a trained professional to repair it and prevent any future leaks. 

Problems with Pan & Pump

If the air handler in the AC unit is in the basement, your drain line may empty condensate into a drain pan, which is then pumped out by a condensate pump. This setup often leads to water leakage because of the old drain pan that gets rusted. When the old drain pan gets rusty, it can develop holes and cracks. Another reason may be due to the condensate pump breaking down, which will then cause the pan to overflow. 

Frozen Coils

If you notice a layer of frost or ice on the evaporator coils, the compressor could get fried. When this happens, you’re looking at expensive repair bills. The worst that could happen is that you may need to replace the unit. 

Reduced airflow over the coils can clog the air filter; therefore, it clogs the coils. Another reason will be a leak in the refrigerant. 

Dirty & Damaged Coils

If you haven’t had your AC unit maintained, then dirt could have accumulated, which causes water to leak inside your property. Lack of maintenance can have the coils be covered with dust and grime. On the other hand, the insulation outside of the coils may already be cracked or damaged. 

Whatever the reason is, the condensate might not be able to run down the coils and down the drain line. What happens here is that it will get diverted by the holes in the insulation and by the accumulated debris. 

So, if you’re seeing small drips or puddles instead of a large amount of water inside your home, then it’s likely the drips are coming from the evaporator coil.
