Ok, last time my unit went out and was able to fix it with the help here but now I have another problem.

My unit outside is working and inside as well but this morning not much air was flowing so I had no time to check everything so I turned the unit off and left the Fan on ON to melt the coils which I guess are also frozen just like the outside pipes and also the tank inside the outside unit was covered in ice. Before I left to work and saw everything was melted I turned it back on and my wife just now during her lunch break went and checked it out and said it was frozen again but not much like in the morning and air was flowing a little better but maybe it's just starting so I told her to turn it off and put the fan on the ON position to melt the coils again and with the heat here in Houston it doesn't take long to melt outside.

*All filters are new and no obstructions to flow in the room.

My question which of the following sounds more of the problem:
- Coils are dirty
- Leak
- Not enough refrigerant
- Other

Could be any of the 4
If its number 2 or three you need to have it checked by a hvac tech
Number 1 you could deal with yourself if you have the no-how
The number 4 covers a lot, so check on 1-2-3 first

Thanks, I'll do the first as I was able to change the motor, capacitor,transformer and board by myself and get it working so on the know how I think I can handle it. Oh, almost forgot, I couldn't have done it with the help from this site.

If I see the coils are clean then I will have to get someone to check the other because I don't have the equipment or license to do it.
