Copper pipes are iceing over. I shut it off and they melted. so I turned it back on and it was working but now the pipes are iced over again.
On a "Non Heat Pump" unit, icing of the pipes is not good. It is an indication that you either have a low freon level (Charge), low load, wrong superheat.
A low load usually means, in this case, something wrong with the air flow. Clogged filter, wrong fan speed, something blocking the return air grill, like a chair/ blanket, etc.
If low on charge, the evap (Indoor Coil) will ice up and the ice will then slowly creep along the pipe untill it gets to the outdoor unit. This is really no good. Air cannot go thru solid ice so naturally there is no cooling happening.
If a company replaces the outdoor unit (Condensing Unit), there is no warranty on the indoor unit. I do not know of any company that will repair an indoor coil (Evap). Just not smart money. They have to capture the freon, open the system, make the repair, ensure the correct level of freon is in the system, and most time, add a filter/ dryer for additional filtering and drying of the freon. With all that, no one is going to patch a leak on an old coil because if it leaks now, it's going to have another soon. You'll just be chasing leaks and spend money after money. Hope that makes sense. HVAC companys have to follow the EPA rules too. Leaving a system leaking above a certain percent of it's total charge is a major no-no. They will not do it.
Hope this helps clear up a few things and good luck.

My ac unit was replaced 08/07& when it was replaced, it cost $1600. It would have an additional $1000 if I had also replaced the coils. My pocket opted not to do that. After the initial install my home still wasn't cooling, so they came back out and checked the unit then added more freon. It then started cooling the house. In 07/08 I'm having the same problem of my unit not cooling. The same company came back out & he stated that I have a slow leak. I can either pay $1000 to replace the coils or he could add freon & it would cost me $118. I opted to pay the $118. My coil outside now has ice on it again. I've turned only the fan on to let the ice melt and also changed the filter. It started cooling but after a while the ice came back and my home is hot again. What should this company do for me to fix my problem. I don't have $1000 to replace a leaking coil and I definitely can't keep calling them out to my home to add freon every other week. Isn't there some type of warranty. I never had this problem with my old unit. What do you suggest?
