If you are running unit hard to cool building, then the probable cause is it is working too hard. A residential unit is designed to maintain a set temp. if there is too much difference between inside temp and temp desired the unit will work too hard to " catch up ". solution, turn off ac unit, remove ice build up ( you can use a garden hose ) then set thermostat to 3-4 degrees below indoor temp. Once it has lowered temp, keep going in 3-4 degree increments until temp desired is reached.

Is freon added to the outside or inside of an AC unit?
you add the refrigerant in your outside unit but still is going to circulate to your inside unit doing a complete loop
Does covering an outside AC unit and keeping the sun off of it make it run better?
depends on what you mean by covering. if the unit is shaded with no restriction of air flow in any way the answer is yes. that simple.
Why is your outside ac unit blowing cool air?
the compressor is not running. Check your breakers.
Where is the capacitor located on an outside ac unit?
near the compressor on the wall of the cooling condenser
How do you check the breaker on the outside ac unit?
Even though the A/C unit is outside, the breaker for it will be in the entrance panel box inside your home. It should be clearly marked.
Should the outside unit ac fan be blowing cool?
No the out side fan is for venting heat away fromt he unit.
Why is discharge line leaving outside unit cold on central ac?
The expansion device inside the outside unit expands the refrigerant gas and as a result, the discharge lines chills
What causes the outside AC compressor unit not come on after 7PM?
Improperly programmed programmable thermostat.
Where Is the freon located in your ac unit?
Throughout the entire system, inside, outside and in the connecting piping.
Quest about window AC unit can the temperature i have it set to be warmer that the temp outside but cooler than the temp inside my place ie 67 outside 82 inside ac at 76 is this okay?
Yes it`s ok. For a window unit outside temp does not matter. Thermostat operates according to the indoor heat load.
Want a wiring diagram from ac condenser to furnace?
I think you mean from the furnace to the ac unit as the ac unit does not power anything, so here is the low voltage wiring schematic from furnace to ac unit.

Does an outside ac unit have freon?
The proper term is actually refrigerant - Freon is a specific brand name trademarked by DuPont for a series of CFC and HFC refrigerants - thus, an AC system only has Freon if it has the product manufactured by DuPont. Answering your question, yes, an outside AC unit uses refrigerant, although it's normally not the same type used in automotive AC systems.
