The evaporator coil is an essential part of the cooling system in your home, and evaporator coil leaks can be destructive to the air conditioner. There can be many causes of evaporator coil leaks, but corrosion is one of the significant causes of leakage in humid parts of the country.

This corrosion occurs outside when formic acid creates microscopic pinholes on the coil’s surface. Acid forms from a chemical reaction between condensation on the coil, oxygen, and the copper coil.

Here, in his blog, we will discuss some causes of evaporator coil leaks in your AC.

1) Improper installation

Causes of Evaporator Coil Leaks

 

If you’re dealing with a newer system and water is leaking, there’s a chance that the system was not correctly installed. If the condensate trap is not set up perfectly, it will keep draining inside your home rather than outside.

In this case, you’ll need a licensed professional Rockville Air Duct Cleaning service to fix improper installation.

2) The drain line is disconnected

While somewhat rare, the drain line connected to the drain pan can become loose or disconnected. It will occur when swapping out the air filter or if someone is working nearby the unit. Air conditioner leaks may occur when the drain line disconnects from the pan.

To eliminate the causes of evaporator coil leaks, check your air conditioner to see if the drain line is fully connected to the coil drain pan and if the drain line is disconnected. We recommend calling a professional to resolve this issue right away. Schedule an appointment with Rockville Air Duct Cleaning today.

3) Copper pipe erosion

This is among the most common causes of evaporator coil leaks. As your air conditioner operates, the copper tubing in the evaporator coils can begin to erode. When the corrosion occurs, small holes develop in the evaporator coils, which leads to small leaks that are hard for homeowners to detect.

After some time, all of your refrigerants can end up leaking out and causing your air conditioner to operate poorly. 

4) Physical damage

Any physical damage to the evaporator coil can affect system function, and if severe damage occurs, it will create openings in the coils that cause them to leak.

5) Evaporator coil is dirty or cracked

If you see a tiny dribble instead of a bigger one near the air heating system or air handler, water may thrive off the evaporator coil rather than the condensate line. This can take place if holes in the insulation around the coils redirect the water or if the coils are soiled.

Leakage is a typical air conditioner problem. The best way to eliminate the causes of evaporator coil leaks is to keep up with annual air conditioning maintenance with Rockville Air Duct Cleaning.
