When an air conditioner freezes over there are two main reasons.
1. Something is dirty - it could be the coils outside the house, the coils at the unit inside the house, and/or a dirty air filter. If any one or more of these are dirty the air flow is restricted. Without warm air giving off it's heat to the air conditioning coils, the AC system will freeze itself.
2. The system is low on refrigerant. This generally takes more tools and knowledge to test and correct. It's best to get an HVAC tech to do take care of that.
In this video I show how I cleaned the evaporator coils to my air conditioner. They were really dirty. The other problem I had was a dirty air filter.
It's also best to get an HVAC tech to clean the evaporator coils too, but with a fair amount of caution and patience one can do this and save the expense of paying a tech to do it. However, one careless slip resulting in puncturing a refrigerant line and you WILL need a tech to fix that and it will probably cost more money overall than the service call you are trying to avoid by cleaning the coils yourself
Additionally, there are some fairly sharp edges and one can suffer a serious cut from just a split second of inattention.
Go slow and pay attention.
You will break it or it will heat up the house even more without hanging the back out the window. If it's blowing cold out the front it'll blow hot out the back with in/out split almost even=no cooling. Exhaust to outside, no options.
The F0 error code indicates that the control board detects a stuck key on the control keypad. This is often caused by a bad control keypad but it can sometimes be caused by a failed electronic control board in the oven console. A technician will normally determine which component is causing the problem by
shutting off the breaker
and unplugging the ribbon wire cable for the control keypad from the electronic oven control board in the console. The oven would then be powered back up to see if the F0 error code returns with this ribbon wire cable disconnected. If it does, then the problem is with the electronic oven control board. If it does not return, then the control key panel will need to be replaced. I normally recommend that you have a service technician repair this type of problem.

The Sharp AH-A12LEV air conditioner uses a maximum 12,000 BTUs of energy from the 220V electricity input. Horse power isn't usually calculated for HVAC systems.
I hope this helps.

(due to machinery inefficiencies, the output cooling is ~9,600 BTUs)
