What Causes Air Conditioner Leaks? October 28, 2019

What Causes Air Conditioner Leaks?, Ashland, Kentucky

Your AC unit allows you to keep your home comfortable, but issues with various components can lead to severe damage to your space. Even a minor air conditioner leak should be addressed immediately. The water could drain inside your space, causing mold growth and additional damage. The excess moisture can also cause rust buildup and short-circuit electrical components. To take better care of the equipment, below are three reasons that your unit could be leaking. 

3 Reasons Why Air Conditioners Leak

1. Clogged Condensate Drain Line

When the condensate drain line is clogged, water will build up in the channel. With nowhere to go, it will leak from the air conditioner and settle inside the house. Dirt, mold, and rust buildup can cause blockages. To check your unit, locate the outdoor condenser component and inspect the casing for the drain line opening. Stick a long broom handle in it, and, if met with resistance, there’s most likely a clog.

2. Low Refrigerant Levels

Hot air is released over the coils before leaving the unit. Running low on refrigerant can also cause the evaporator coil to freeze and the condensate pan to overflow. A refrigerant leak could be to blame for the low levels, and a hissing sound often accompanies it. Muggy interiors could also point to a problem, so be aware of changes in your home’s temperature and moisture levels.

3. Dirty Air Filter

When the filter is covered in dust, pollen, dirt, and other grime that is pulled into the system, it can cause excess water to accumulate in the condensate pan, leading to leaks. This happens because air can’t pass through the clogged screen. Without a steady supply of air over the evaporator coil, it will frost over. When the frost eventually melts, it ends up draining into the pan. In addition to leaks, the strain a dirty filter puts on components can cause premature breakdowns. High cooling costs could be a sign that the filter needs to be cleaned or replaced.
