Understanding the Causes of Air Conditioner Coil Leaks and Prevention Strategies

Spread the love

Air conditioners are a vital amenity for homeowners in Hamilton, particularly during the intense summer months. The ability of these systems to maintain a comfortable indoor climate is crucial.

However, owning this valuable asset requires regular maintenance and addressing potential repair issues. A frequent problem encountered in AC units is the leakage of the air conditioner coils, also known as evaporator coils.


The Evaporator Coil in Your Air Conditioning System


Understanding the role of a leaking coil within the HVAC system is essential. Indoor units contain an evaporator coil pivotal to the system’s operation. Heat is absorbed from indoor air and cooled before circulating into your home.

When these coils leak, the air conditioner’s overall performance significantly declines. This malfunction manifests as reduced cooling efficiency, necessitating frequent refrigerant refills, increased air conditioning costs, and the need for repeated searches for “AC repair in Hamilton.”

Grasping the reasons behind these leakages and their prevention is crucial for homeowners.


Identifying the Root Cause: Why Do AC Coils Leak?


Leakages in the evaporator coil typically stem from two main issues: corrosion of the coil’s copper tube and the presence of volatile organic compounds (VOCs) in the environment.


Corrosion in the Coil’sCoil’s Copper Tube

The most common cause of leakage is corrosion in the copper tube of the coil. This occurs due to the chemical interaction between water, copper, and VOCs in the surrounding area. These interactions lead to formic acid build-up, promoting rust on the copper tube and eventually causing leaks.


Volatile Organic Compounds in the Atmosphere

Everyday lifestyle activities contribute significantly to the presence of VOCs around us. Items like household cleaning supplies, personal products, and even wall paint are sources of VOCs that increase the chemical concentration in indoor air. When this air interacts with the air conditioning system, it can accelerate the corrosion process, especially in coastal cities where environmental factors like salt are prevalent, increasing the demand for “AC repair in Hamilton.”


Addressing the Leakage Issues: Prevention and Maintenance


Understanding the causes of evaporator coil leakage is just the beginning; proactive prevention is critical to avoiding this common HVAC problem. Here are several strategies homeowners can implement:


Regular Maintenance is Key

Regular AC maintenance prevents rust build-up and enhances system efficiency. Establishing a maintenance contract with a trusted local HVAC contractor ensures your AC unit’s long and productive lifespan, saving you from unexpected, costly repairs.


Limiting VOC Emission

While eliminating VOCs from your home is challenging, reducing their emission is feasible. Choosing natural, non-toxic alternatives for cleaning products and other daily-use items can decrease indoor VOC concentrations, thus minimizing corrosion and the need for frequent “AC repair in Hamilton.”


Invest in an Air Purification System

Installing an air purification system can be beneficial. These systems help reduce the VOCs and other contaminants that contact your air conditioner, thereby minimizing the risk of coil corrosion.
