Minimum outdoor temp for running AC?

During the spring and fall, a sunny day can warm our house up to uncomfortable levels even though the outside temp may only be in the 50's. (The sun is pretty intense in Utah.) My wife and I both have bad allergies so we don't open our windows. Is there a minimum outdoor temperature below which I should not be running the air conditioner?

Thanks.

the unit can be run in cold temps with a head pressure control and crankcase heater...... however, on a typical a/c it would be best to not run the unit when the outdoor temp is below 70.

Check with MFG. Most co make a cold weather kit to install on there units. It might include a hard start kit also. Like hvactechfw said crank case heater, hard start kit and it can cycle the condenser fan off and on to to keep the temps. and pressure in check. Paul
