Hello, If its an older system the problem is caused by a dirty cooling coil and blower wheel in many cases.

.

If its a newer system, the problem is caused by not enough air flow or not quite enough refrigerant in the system.

.

Not enough air flow can be solved by setting the blower to a high speed (you need a technician for that).

Or not enough air is caused by air ducts slightly too small for the air flow needed,

.

Also, most systems will ice the coil if you set the thermostat below 70F when its also cool outside.

.

Look all that over and let me know what you think is most likely in your situation.

.

We can go from there without a time limit, In depth with as much detail as needed , after you rate this answer:
