Watch Your A/C System's Coolant and Oil Levels

By · January 16, 2011 · Filed in Maintenance, System Reliability

here are hundreds of moving parts in a roof top heating and cooling systems. Many of these parts require the coolant and oil level in the system to be at proper level to provide lubrication and cooling. In fact, some A/C system with low refrigerant level may maintain proper room temperature but overheat the motor windings of the compressor which will thermal age the compressor. Next to an A/C set too low, this is the #2 leading cause of premature compressor failure
