Corrosion is particularly common in condenser units within HVAC systems due to their exposure to moisture and external environmental factors. Condensers operate by dissipating heat and typically have water present, which can lead to rust and deterioration of metal components if not properly maintained. The presence of pollutants or salts in the air, especially in coastal areas, can accelerate this corrosion process.

While evaporator coils and compressors can also experience corrosion, the nature of their operations and the materials used in their construction often allow for better protection against corrosion compared to condensers. Thermostats, on the other hand, are primarily electronic devices and are less susceptible to corrosion than the metal components found in evaporators, condensers, and compressors.
