When you say "our" are you referring to your AC at home? If so, take a look at the larger of the two lines that go into the outdoor unit. Is there some condensation forming on it? If not it might be time for a "tune up" Is the outdoor coil clean? If not, turn the system off and turn off the power to the outdoor unit. Take a hose and wash down the outdoor coil. Allow some time for the coil to dry or use a leaf blower and blow it dry then restart the system and check for condensation. Make sure your air filter is clean and in some cases, turn your fan switch on the thermostat to the on position to allow the furnace fan to run continuously.

On the outdoor coil, I think you can buy coil cleaner from places like Lowes or Home Depot. A not so easy thing to check is the evaporator coil. Sometimes debris gathers on the inside of the coil, the side you can't see, that reduces airflow across the evaporator.

You might have already known these things but many people don't.
