First, unplug the contactor from all wires. Next, take a multimeter (available at most hardware stores) and measure the current flow through it. Connect the low-volt terminals of the multimeter to the contacts. If readings are low it is likely that the contactor should be replaced. Replace the contactor, and reconnect the wiring. After the repair is complete, make sure you turn off the power supply to your air conditioner.
Installing a central HVAC system thermostat that can be programmed to adjust to your desired temperature is a must.
