    It could be just depends on alot of things.  first has it been really hot where you are like its been last few weeks?  we've been in upper 90's here so our A/C runs continuously.   

    1st thing how old is that filter?  If it's older than a month you might /probably need to replace it.How long has it been since the units been serviced?    If its been more than a year it should be checked.  coils, refidgerent level ect.

    Try taking the look at the brains of the unit (Thermostat) it may be on a wrong setting or it may be faulty.

    You could be running low on freon or whatever it is they use as refrigerant these days.

    Is your house comfortable? 

    How is your electric bill? 

    Maybe your FAN switch at your thermostat is set to ON instead of AUTO? 

    If that's the case, then your blower in your furnace is always running.  The general advantage for that would be to keep your room air constantly circulating, and possibly run it through an electronic air filter to remove cigarette smoke. 

    Otherwise, set the FAN switch to AUTO.

    sure -- it could be low on refrigerant, it could need cleaning, the filters could need replacing.  and it could merely be a very hot summer in a house with inadequate insulation in the attic

    If it is 90s outside and you set the thermostat to 70, the AC will not stop running.  It will stop at night when the temp goes down to low 80s or high 70s.  Replace the air filter if you have not replaced it since Obama was president.

    Wash off the outside fins with the hose.

    Its summer. It will constantly run because it is hot outside. Even if you set it on high to 70 degrees or higher it will be running. You need AC. Don't shut it off. Keep it at 68 or lower.

    First of all, check your settings to be sure nothing changed.  

    Many units have a "fan" setting that will keep the fan running even when the AC compressor actually isn't running.  The fan options are usually "on" or "auto".  You want the fan to be on "auto" so that it only runs when the AC compressor is running.

    If your unit has a filter - make sure the filter is clean.  Change or clean the filter if needed.

    If your area is experiencing temperatures over 90 or high humidity, then it may just be an issue with the air not being able to keep up with the heat outside.  If the temperatures are not unusually high or your unit has not had issues in the past, then it probably does need  a service check to see if anything is wrong.

    You can schedule a service call to have it cleaned and checked and the tech that checks it will be able to tell you if anything is wrong with the unit.

    I'm curious...How do you "feel" the AC is constantly running?

    It either runs or it doesn't.  If it runs then there are no issues.

    The unit outside is NOT your AC, it is basically a radiator like in your car.  The coolant in the AC unit circulates and heats up. 

    Once it reaches a specific temperature it moves to the outside unit to get cooled down.  While that is happening the coolant outside moves inside.

    If the unit outside is constantly running then it is constantly switching over heated coolant for cooler coolant.

    If you have any concerns you should probably get someone in to check it to check your coolant level.
