AC coil corrosion is a major HVAC problem that can cause serious problems. As is the case for any other HVAC-related issue, preventing coil corrosion is better than repairing it. With that said, in cases of advanced AC coil corrosion, which leads to refrigerant leaks, the air conditioner may not be reparable, and therefore, you may have to replace the entire system. However, these systems can be extremely susceptible to corrosion if not properly set up and operated.
What is Coil Corrosion
Corrosion can result from a chemical reaction with fluoride or chloride, as is often seen in air conditioner coils—the pitting corrosion results in metal consumption by fluorine or chlorine. As a result, holes can develop in the coils and become larger. If your refrigerant needs to be recharged, this might be why. Formicary corrosion can damage or corrode your air conditioning unit’s coils, which can also lead to airflow problems. In addition, Formicary corrosion creates microscopic holes within coils, which could eventually form leaks and lead to system breakdowns.
How to Prevent It
The Prevention of AC Coil Corrosion is an important task that every mechanic should take on. By taking proper precautions, you can help protect your coils from corrosion. Here are a few tips to follow:
Understanding Corrosion
Understanding Coil Corrosion can help prevent it from happening in the first place. Coil corrosion is an issue that often occurs in AC electrical systems. It’s a common problem that can lead to loss of power and even fire. Proper diagnosis and prevention are essential for avoiding coil corrosion.
Cleaning the coils
There are many ways to prevent coil corrosion, but one of the most effective methods is regularly cleaning the coils. Cleaning the coils can help remove any built-up dust and deposits, and it can also improve the performance of the AC circuit. Cleaning your coils also helps protect them from being corroded by environmental factors like moisture or salt.
Coil corrosion on the outside unit
After cleaning the outside unit’s AC crossbars twice yearly, you will prevent them from rusting. Here’s how to go about doing it:
Turn off the power supply to the outer unit at the main switch
Detach the side panels and the top grill of the unit Begin
Use the inner part of the condenser unit with a garden hose
Excess water has settled before returning the panels to the top rack.
Conclusion
AC coil corrosion is a problem that can be prevented using proper maintenance techniques. Keep your AC coil in good condition by following the above tips to avoid corrosion.
