If the ice formed while the unit was operating it is a heat pump. The defrost board or whatever other control you may have to initiate the defrost cycle is probably bad. Switch the unit over and run the air conditioning, that wil defrost the ice until you can have it repaired.

∙ 14y agothe filter is the first thing to check ,then it could be a dirty a-coil. if the unit has run fine in the past check those things first if those are fine then it probably could use some freon

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
How cold should be copper lines on ac unit?
There is no real set temp for the lines ,the bigger thing is the heat that the outside unit is producing when the unit is on. A normal functional AC unit will be around 105 to 110 degrees as for the copper lines they should feel pretty cold to the touch like an ice colds beer feels in your hand......
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
Where Is the freon located in your ac unit?
Throughout the entire system, inside, outside and in the connecting piping.
What causes the outside AC compressor unit not come on after 7PM?
Improperly programmed programmable thermostat.
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.
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.
What's wrong if the house was hot and you noticed ice on the outside central air unit lines and today lines are ice free and the house is still hot and youpushed the reset button on the outside unit?
Low on refrigerant or dirty filter.
