Maybe dirty air filter or slow fan motor or if the ice build-up does not cover whole of coil it maybe short of gas due to minor leak.

Why does my central air keep freezing up?


An air conditioner freezing up is either low airflow or low on refrigerant. If the filter is clean, then check the refrigerant level, blower running at proper speed, make sure indoor coil is not dirty or restricted. Make sure that the duct outlets are all open and some have not been closed.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

The unit keeps freezing up solid even on energysaver


Change or clean the filter and clean both coils, no air flow or reduced air flow, the coil will freeze. It will also freeze if its set to cold 72 min. setting. Example if your room temp is 72 degrees, than the air will be 52, and the coil temp is 32 degrees, any moisture will freeze. Hope this helps

I have a Coleman Central Air Conditioner/Heat Pump. On the cooling mode the coils inside the unit in the basement continue to freeze up causing no air flow. I relpaced the filter thinking it might have...


The most common reason for freezing up is 'air flow,' and since you've already changed your filter - have you checked out the coil (the one that cold air comes from) to see if it's clean? If the filter you changed was really 'bad dirty' then it's a good bet the coil could be dirty also - thus restricting the air flow.

If you're satisfied that the coil is clean - about the only other thing it could be - is 'low on refrigerant,' which of course will take a Service Tech to find the leak, repair it and then re-charge the unit with refrigerant.

One other thing you might think about - are you running the blower motor on 'low speed?' If you are then put it on 'high' and see what happens.

Again, the most likely cause of your problem is air flow or 'low load,' - so I would really look hard for an air flow problem of some sort.

hope this has helped a little

Frigidaire central unit freezing up leaking


The coil freezing can be caused by a couple of things. 1) Not enough air flow over the coil or 2) A low refrigerant charge. First make sure that the indoor fan is running. Then check your air filters and make sure your evaporator coil is clean. After that you can get the refrigerant charge checked. The lower the refrigerant pressure is, the lower it's boiling point is and when it gets below 32F then the evaporator coil and usually the low pressure line freeze up. The leaking you were talking about is probably from the ice melting. Hope this helps.

Lines freeze in central air unit


If you are not certified to do H V A C then I highly recommend that you call in the pro's. However there is something you as a homeowner can do. Start by checking the air filter. if it is too dirty it will slow the air flow across the coils and cause the coils ti ice. The line freezing is a sign that your coils are beginning to ice or already have. This is also true if the coils are dirty. You can check this by removing the air filter and using a flashlight to look up inside of the air handler. If they are dirty then you can clean them with a solution of water, mild dish detergent and a soft bristle brush. Be sure to rinse them thuroly. If this does not fix the freezing problem then you may very well have a small leak and need to have some refrigerant added. hope this helps. Good luck.

Central air unit


Make sure you let the blower run for a while after it freezes to make sure there is no more ice. Then run the unit. Check the refrigerant lines the large copper line that has insulation on it should be cold to the touch. If it runs for 10 minuits and is barely cold or warm you are low on refrigerant. If its starts out nice and clod then check your filter and retun ductwork for blockage you should not have noisy return air vents or that can indicate you have too small a return.

Also are the outdoor unit and indoor coil a match? Same tonage?
Is the furnace big enough to handle the tonage? (fan size)

No cold air


Freezes up is only caused by either low on freon or low aiflow across the indoor coil, which could be caused by dirty or blocked filter ,,dirty fan blower wheel or pluged coil.
