Causes of AC Corrosion and How to Address Them

In this week’s blog, we discuss some of the leading causes of AC corrosion as well as detection and repair methods for subsequent pinhole leaks.

As HVAC professionals know, AC/R systems with copper coils are ubiquitous in day-to-day life. Unfortunately, pros also know that AC corrosion causes these systems to become inefficient and fail over time. There are plenty of contributing factors that lead to AC corrosion and refrigerant leakage. Knowing your clients’ risk factors and being able to determine the root cause of formicary corrosion in their units is crucial. In this week’s blog, we discuss some of the leading causes of AC corrosion as well as detection and repair methods for subsequent pinhole leaks.

Common Causes of AC Corrosion

Advancements in construction and insulation have led to homes and businesses that are more energy-efficient. Although this is an excellent trend in terms of energy consumption, buildings with fewer drafts and less airflow can create the perfect environment for AC corrosion to occur. Chemicals contained in paints, cleaners, and other household items can become trapped inside buildings. These compounds can react with copper evaporator coils, resulting in pitting and formicary corrosion. In addition to internal factors, external factors such as saltwater and high pollution in the area can have a negative impact on condenser coils. If your clients’ AC/R systems have recurring and extensive damage from corrosion, you may have to replace the unit or suggest that they invest in replacements or protective coatings for their copper components. However, if their systems experience an average level of corrosion and leaks, detection and repair are possible with help from Cool Air Products.

Detecting and Repairing Pinhole Leaks

There are a few different methods for detecting holes in AC/R systems. Along with costly electronic leak detectors and nitrogen tests, HVAC professionals can pinpoint suspected leaks using Brilliant, an injectable leak detection product from Cool Air Products. Brilliant travels through the system to the site of any leaks and fluoresces under any UV light for easy and accurate results. For holes up to 5mm in diameter, technicians can utilize AC SmartSeal External, a leak repair putty that provides a strong and permanent seal. Simply knead the putty together and apply it to the site of the hole following the manufacturer’s directions.
