My AC unit keeps freezing up on the copper lines going into the house from the outside unit. It also freezes up on the inside lines and the air is not cooling my home down.

  • Ruby162 Jun 09, 2008

    Our air conditoner keeps freezing over.. How do I prevent this...It doesn't completely make sense what you wrote on the "suggestion" section.



    I still think its a good airconditioner but I need some help on preventing it from freezing over.. We mainly use the airconditioner at night..during the day its always off......

    First we wiped off the snow that built in it ( we noticed there was a problem when no air was coming out of the air conditioner) then we notice a layer of ICE in our air conditioner.. so I took the hair blower and melted the ice and cleaned the air filter to it...



    But I definately need a more practical way of preventing this from happening again.. Also could it start a fire from being built up with ice and snow?

Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.

Ours kept freezing over last summer and we couldn't figure out why. We eventually had some ac people come and look at it and they said the unit was not large enough for our house. We got a larger unit and we haven't had a problem since. You should check what square footage your ac unit is rated for. http://www.dawncohvacoh.com/services

Our house is hot! The ac unit outside comes on and freezes up, and the blower is not coming on. We have had the inside thermostat changed and freon added and now a new capasitor but no luck.....HLEp

Man, it sounds like you have a heat pump with a bad defrost board or reversing valve. I assume your description of the unit outside freezing up is the condenser and the blower you refer to is the condenser fan motor. Or, is it the big copper line to the compressor that is freezing up? If so, have someone stand by the inside blower and listen for a click as you move the thermostat fan switch from auto to on a couple of times., Make sure at the time you are testing that the thermostat is in the off position. Those 2 switches operate separately. If you hear those clicks during the test you probably have a bad blower motor if there are are no clicks you may have a bad blower relay or board. Hope this helps good luck.

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

Ac line freezing up from outside to house

AC lines freeze on the outside of the house when the insulation for the copper tubing is damaged or missing. if this is not the case in your situation, there may be a small refrigerant leak in the tubing.

Hope this helped you and thanks for choosing FixYa.

Heater,....

First check your air filters and make sure the inside and outside coil are clean. If they are clean and you are getting good air flow over the coils then you probably will have to get the unit charged.

The copper line going from my outside unit up to the inside unit keeps freezing up. This on the outside of the house.

This sounds like you are low of refrigerant. Or you evaporator needs cleaning. Have it check out to see if you have a leak in the system

Goodman Model CK60-1C with White Rogers mercury tube thermostat

The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.
