Why won't my AC cool below 76?
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.

How do you check if a condenser is clogged?
With a clogged condenser, you will notice higher pressures even though you have the right amount of refrigerant in the system. These higher pressures are noticed on both the high and low side. Condensers are subject to clogs because of the leftover particles in the refrigerant.
How do I know if my evaporator coil is clogged?
One thing that will be noticeable when the evaporator coil is dirty is that your AC won't produce air that's as cold as it should be. When the heat transfer is reduced, the efficiency of the cooling process is impacted. If it becomes clear that the AC isn't cooling your air, have the evaporator coil inspected.
