Evaporator coils play a critical role in the cooling system of HVAC units. However, these coils are prone to leaks, leading to inefficiency and costly repairs. Understanding the causes of evaporators coil leaks and how to prevent them is essential for maintaining your HVAC system. Consulting with the evaporators supplier in usa can also be helpful.
Common Causes of Evaporator Coils Leaks
The list of common causes includes:-
1. Corrosion
One of the most common reasons for evaporators coils leaks is corrosion. Over time, moisture and chemicals in the air can corrode the copper coils, leading to pinhole leaks. This issue is often more prevalent in homes with high humidity or poor air quality.
2. Formicary Corrosion
A specific type of corrosion known as formicary corrosion can also cause leaks. This occurs when organic compounds like formaldehyde react with the copper, forming small holes in the coils. These compounds are commonly found in household cleaning products and building materials.
3. High Pressure Inside the Coils
Another cause of leaks is excessive pressure inside the coils. When refrigerant levels are too high, or the system is overworked, it puts additional strain on the coils, increasing the likelihood of leaks.
4. Age of the System
Older HVAC systems are more likely to experience evaporator coils leaks. As the system ages, the coils become more vulnerable to wear and tear, making leaks inevitable after years of use.
Evaporator Coil Leak Symptoms
Poor performance is a common sign of a broken evaporator, which is crucial for removing heat from the air. Alaqua, a USA-based supplier, offers various processing equipment.
There are further signs, though, that indicate damage to your AC evaporator:
The AC evaporator can be damaged by leaking coils or cores, causing weak or absent cooling, causing unusual odors when using the air conditioner, preventing the compressor from turning on due to a leak, and causing the air conditioner’s temperature to fluctuate, even if it’s a minor leak. These symptoms can significantly impact the effectiveness of the air conditioning system.
How to Prevent Evaporator Coil Leaks
Tips to prevent evaporator coil leaks are:-
1. Regular Maintenance
Regular maintenance and scheduling annual HVAC inspections are crucial for preventing evaporator coil leaks and catching potential issues early. Cleaning the coils regularly will also help prevent corrosion and other issues.
2. Use a Refrigerant Additive
Adding a refrigerant sealant or additive can protect the coils from corrosion. These products coat the inside of the coils, reducing the risk of leaks caused by formicary corrosion or other chemical reactions.
3. Improve Indoor Air Quality
To prevent formicary corrosion, it’s crucial to maintain good indoor air quality. Reduce the amount of organic compounds in your house by using air purifiers or increasing ventilation. This simple step can significantly extend the life of your evaporators coils.
4. Replace Old HVAC Units
You might want to think about upgrading your HVAC system if it is more than ten years old. Modern systems are more energy-efficient and designed to resist corrosion better than older units. Upgrading your system will not only prevent leaks but also save you money in the long run.
To Wrap Up
Evaporators coil leaks can be costly and disruptive. However, by understanding the causes and taking preventive measures, you can significantly reduce the risk of leaks. Regular maintenance, improving indoor air quality, and using protective additives are all effective ways to prolong the life of your HVAC system.
