What you are looking for: Visually restricted or plugged filters. How to correct potential issues found: Replace all with equivalent- twice a year on spring and fall startups or as needed. Possible consequences of neglect: High/excessive current or amp draws on supply fan motors and contactors result in premature component failure. Poor or no airflow, low suction pressure, low superheat. frosting/icing of evaporator coil(s) and! or slugging of liquid refrigerant back to compressor resulting in premature mechanical failure of internal moving compressor parts. Unsatisfactory/uncomfortable space conditions and unreliable equipment.

What you are looking for: Belts that are out of adjustment, stretched, cracked -there should only be a half inch of belt deflection on the driven side or enough tension so the belt does not slip on startup of associated motor. How to correct potential issues found: Inspect, adjust or replace as needed. An inspection at least twice a year can help extend belt life. A properly adjusted/aligned belt can last up to a year or more. Possible consequences of neglect: Poor or no air flow, frosting/icing of evaporator coil(s), slugging of liquid refrigerant back to compressor resulting in premature mechanical failure of internal moving compressor parts. Unsatisfactory/uncomfortable space conditions and unreliable equipment.
