Omega Environmental Technologies, a distributor of aftermarket mobile air-conditioning parts and tools, offers some preventive maintenance tips that will keep a fleet's air-conditioning systems working at peak performance during summer.
Inspect all hoses for signs of oil seepage and replace if necessary.
Check all drive belts for crack or wear.
Check inlet and outlet O-ring fittings for leaks and replace if necessary.
Evacuate the system.
Check the evaporator coil for debris and replace the intake filter if the unit has one.
Replace all Schrader valves and check the voltage to both the clutch and the blower motor.
Inspect and clean the condenser coil to allow proper airflow through the fins. If necessary, use a fin comb to straighten the fins for proper airflow.
Replace the receiver-drier at least every year. The receiver-drier, which contains a desiccant that absorbs moisture that may occur, should always be the last component replaced in the HVAC.
Inspect the oil for signs of compressor wear, moisture absorption, or other internal problems.
Evacuate the system and recharge.
