What Causes Your A/C's Evaporator Coils to Leak?
Whenever you have an appliance large enough to cool or heat your entire house, there is always room for problems. Air Conditioning Evaporator Coil Leaks can become a very expensive headache for a homeowner. With all the Florida conditions such as salty air, high humidity and long periods of heat, these all play an important role in reducing the life expectancy of your Air Conditioner. As a Florida homeowner, you are able to minimize the issues that may cause the evaporator coil to leak.
When you are inspecting your system, it will ease your mind to know that water dripping from the coil is completely normal. This is due to condensation that forms when the cool air passes through the coils. However, if you are seeing water overflow the condensation pan, then you may have a serious problem on your hands. These pans are intended to catch small amounts of condensation. So if it is overflowing, that usually means a drain tube has become blocked or plugged up which will cause water to overflow.
If you notice any of these issues then you want to call your local Air Conditioning company right away. You may not know that refrigerant is escaping the leak since you are not able to see it with the naked eye. Your HVAC technician will be able to tell just by how often he is needing to top off the refrigerant. If you have recently purchased your new AC system, the evaporator coil leak may be due to manufacturing defects or even by a faulty installation not done by a professional company. If you can catch these issues early, the repairs to your system should be covered by your warranty. Most repairs are simple enough to tighten connections or re-solder joints. All of this should be covered by warranty.
One of the most common causes of evaporator coil leaks in older equipment is Formic Acid build-up. Chemical reactions between moisture, copper coils and Volatile Organic Compounds (VOC's) are what makes up these acidic deposits. These VOCs are known to be in several household chemicals, including paints, personal hygiene products and even in the fabric of new carpets.
To reduce the build-up of formic acid on your evaporator coil, here are a few steps you can take:
Try to minimize the use of household products that contain VOC's. This will keep the build-up out of the air.
- If the weather is nice outside, let some fresh air in. Not only will it allow circulation in your home, but it will rid the stale air that may be holding onto harmful particles.
- Have your HVAC technician clean and examine the coils semi-annually. This will allow a professional to keep an eye on any problem areas that may need further attention.
- Install an indoor air purifier. The UV light will neutralize the VOC's which will reduce any build-up that may occur.
