The Role of Contaminants and Moisture Moisture and acid formation are silent killers of HVAC efficiency. The compressor is the heart of any air conditioning system, and when it stops working, the entire cooling process comes to a halt.
How Dirty Coils Lead to AC Compressor Failure
Mechanical failure is often the final stage of a longer process. Dirty coils and blocked drains force the equipment to work harder, increasing the thermal load on the compressor.
Similarly, a failing relay or contactor can arc and create inconsistent power delivery, leading to overheating and burnout. This causes the compressor to "hard-start," placing immense stress on the windings.
How Dirty Coils Lead to AC Compressor Failure
When moisture enters the system, it can mix with the refrigerant and oil to form acids. When a system is low on refrigerant, often due to a slow leak, the compressor has to work significantly harder to move the reduced amount of coolant.
