Air conditioners have a tendency to "freeze up", leading to little or inefficient cooling in your home. Surprisingly, this may tend to occur when the temperature is below 60 degrees. There are some common solutions to this problem however.

The air filter in the AC unit may be dirty. Check your air filter and make sure it is not dirty or obstructed with particle matter. If it is, then clean it and make sure to stay on a regular cleaning schedule point forward. Poor airflow can bring the machine down quickly.

If the air filter remains dirty for to long it could lead to a dirtying of the coils inside of the machine. This can also be solved by simply cleaning the coils.

Check the tubing which runs into the house. This is typically made of copper and may feel excessively cold to touch. The culprit here may be a loss in refrigerant pressure, most likely from a small leak. Hire a professional to charge the unit with additional freon. You may also want to ask to technician to check for a leak within the tubing itself. If you continue to run the machine you may risk damaging your compressor which could ultimately cost even more money to fix.

When a unit freezes, be sure to check all the copper tubing that runs to it and into your home. If a significant amount of ice has formed it may begin leaking. The tubing may run through a closet and ultimately to the coil which may be in the attic. This could leave you with two areas of concern for water damage. Make sure to keep an eye on exposed tubing inside of the home and keep towels ready. You will also want to take into consideration that drip pan could potentially overflow, or that other water pooling could occur within the attic itself. You certainly don't want to damage your ceiling in the process of fixing a broken air conditioner.
