After floodback and slugging, Park said the major causes of compressor failure, in order of importance, include bad contactors, system leaks, dirty evaporators, dirty filters, dirty condensers, rapid loading/unloading, mis-wired/misadjusted controls, low superheat, and wrong oil for the system refrigerant.

How do I know what size my AC compressor is?

Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.

Are Copeland scroll compressors good?

Superior reliability and energy-efficiency — At the end of the day, what matters most to our customers are reliable performance and energy-efficiency.
