Why won t my AC go below 73?

A clogged and dusty air filter will force your air conditioner to labor in circulating cool air to reach your desired temperature (e.g. your set your thermostat at 73 but the air won't drop below 76). The evaporator coil, which cools the air, will then freeze, forming ice that obstructs the airflow.
