Evaporator Coil Failures and Refrigerant (Freon) Leaks
The common problem of refrigerant leaks often stems from the evaporator coil section of the home air conditioning system.
Historically, most evaporator coils were made of copper tubes inside of aluminum fins that were sandwiched between galvanized steel tube sheets. These surfaces stay wet when functioning correctly during the cooling cycle.
Formicary Corrosion, caused by the Volatile Organic Compounds or VOC’s often found in today’s home environment (often from the building materials of the home, furniture, carpet, hair sprays, etc.), cause the copper and steel to corrode creating many small leaks (this is sometimes called Ant Nest Corrosion) in the refrigerant system.
Galvanic Action, the corrosion of 2 dissimilar metals touching can also play a significant factor in coil failures.
Today, to help prevent these failures, many coils are made with aluminum tubes and tube sheets instead of copper and galvanized steel. Aluminum Coils are much less susceptible to Formicary Corrosion than Copper Coils are.
