A/C unit
My A/C unit fan runs all the time now,I can hear the compressor kick on and off. Has this happen to anyone?

I read your problem as the compressor cycling on and off quickly. If it is doing that then in all probability it is a Freon problem. If it is cooling normally then you will need to check different components to determine the cause.
I did not read that it was short cycling. There can be other issues that will cause the short cycling other than low refrigerant charge which need to be checked out first.
Check the air filters, evaporator (indoor) coil is clean. Also check for air bypassing in the unit, check for a clean condenser coil. Also, the compressor or motor could be going bad.
See it the compressor is cycling off based on the thermostat or on the thermal overload on the side of the compressor. Check the motor amps as well.
To check for refrigerant charge you have to tap into the sealed system with a temporary valve. Then find a leak, remove the charge, install permanent Schrader valves, evacuate the system and finally recharge it.
The OP did not tell us the age of the A/C unit. If it over about 8 years old, I would just replace it before I dumped a bunch on money into the unit.
