Let's be honest, there is never a good time for the air conditioning to go out!  Waiting for it to be repaired can seem like forever. So we're found a simple list of troubleshooting A/C problems and perhaps preventing it from going out in the first place.  First on your list should be regularly changing the filter at least once a month. A clogged filter restricts airflow through the unit, decreasing its efficiency and reducing the ability to effectively cool the air. Check to make sure your windows and doors aren't leaking your precious cool air outside.  Make sure the intake vents are not blocked by furniture or other objects and regularly clean them with a vacuum and duster to keep them free of blocks. Look at what is around the thermostat.  If you have a heat source, such as a TV or lamp near it, the excess heat may be causing your unit to run too often thinking the room is hotter than it is and leading to failure. Now head outside to the compressor unit (the noisy-humming metal object essential to cooling your home.  Make sure plants and any structures are at least 2 to 3 feet away from the unit. Also make sure any tree or hanging structure is at least 5 feet away from the unit. Finally, schedule an annual checkup. Preventive maintenance means your A/C won’t quit unexpectedly.
