Air Conditioner Acid Formation and Removal

In this week’s blog, we will explore the causes of acidic refrigerant and one method used to remove air conditioner acid.

One of the most common causes of refrigerant leaks in AC/R units is the presence of acids in the system. While technicians can patch holes, leaks are likely to reoccur unless the acid is removed from the system. How do these acids form? How can HVAC technicians safely and effectively remove these acids? In this week’s blog, we will explore the causes of acidic refrigerant and one method used to remove air conditioner acid.

Detecting and Treating AC Coil Corrosion

This post will discuss methods of detecting and treating leaks due to AC coil corrosion.

Last week, we discussed methods of detecting and removing acid in air conditioner systems. This week’s topic is somewhat related; AC coil corrosion is often a result of exposure to organic or inorganic acids. Some suggest that the uptick in AC coil corrosion that HVAC professionals have seen in recent years is the result of homes with increased insulation. When airflow is reduced due to better construction and insulation practices, compounds like acetic acid, formaldehyde, and acetone remain inside the home for longer. When these compounds come into contact with copper air conditioner coils, it results in formicary corrosion. This post will discuss methods of detecting and treating leaks due to AC coil corrosion.
