The Importance of Cleaning the HVAC Condenser

BeforesplitIMG_20130719_132215_852If a condenser becomes dirty or fouled, less heat transfer can take place from the refrigerant to the surrounding ambient space. Dirty condensers are probably the most common problem found during a service call next to dirty filters. It is hard to say which one is the most devastating to a system. List below are some the results of a dirty condenser.

  1. Compressor amperage begins to exceed its design limits shortening the life of the compressor.

  2. Discharge gas temperature can reach critical levels causing a breakdown of the refrigerant and oil lead to compressor or system failure. This level is about 225degs.

  3. The suction gas coming back to the compressor is no longer sufficient to cool the compressor motor, again leading to compressor failure.

  4. The condensers air discharge temperature is greatly elevated and if the condenser fan motor relies on it for cooling, it may fail as well.

  5. Flash gas reaching the metering device causing erratic operation, high Superheat and lower net refrigeration effect. Aftersplit IMG_20130719_134050_470
