Suction line filters are generally designed

• A. To be removed after the system is clean
• B. To stay in place permanently
• C. To be replaced after every service
• D. To be removed before starting the system

Answer: (A)

Suction line filters are temporary protective devices used during service to trap debris and moisture and protect the compressor while the system is being cleaned or flushed. They’re designed to be removed once the cleaning and any flushing is finished so they don’t obstruct the refrigerant flow during normal operation. Leaving a filter in place permanently would create a flow restriction on the suction side and could reduce system efficiency or cause problems. Replacing a filter after every service is unnecessary unless it’s damaged or saturated, and removing it before starting the system would defeat the protective purpose during service. For proper operation, the filter is taken out after the system is cleaned and ready to be charged and operated.
