Refrigerant temperature plunges into the range below 32 degrees.
Indoor ac coil freezing up.
If it is dirty that is your problem.
If the filter appears extremely dirty or clogged install a new filter.
If it leaks the lack of pressure will make it absorb more heat than it should.
In the process it also drains a lot of condensation.
In many cases freezing up ac is simply the result of a poorly configured thermostat.
Check your evaporator coil if your air conditioner is freezing up.
Frozen ac coils are caused by refrigerant leaks refrigerant is the chemical that runs through your ac coil changing pressure and temperature in order to absorb heat.
They pull the water out of the air which makes condensation that builds up on the coils.
If your air conditioner is running low on refrigerant due to a possible leak it can freeze up.
This makes the refrigerant lines and then the coils freeze over.
This can also result from running an ac at a sufficiently low temperature for long enough.
At this point the air conditioner won t work anymore.
All sorts of mechanical problems and other issues can cause an air conditioner s coils to freeze.
Normally this isn t a problem because the condensation droplets fall off the coils into the drip pan.
As the coil continues to condense water ice inevitably forms on freezing coil surfaces.
Replace the filter with a new or.
Turn it off remove the filter.
Turn the fan switch on the thermostat to on.
Let it run for a couple hours to thaw the coils.
If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation.
The more the refrigerant has to expand the cooler it makes the temperature.
This happens because the refrigerant in the evaporator coils can no longer absorb the heat needed for the coils to warm up.
The evaporator coil is prone to freezing primarily because it transfers heat or evaporates it from the indoor to the outdoor air.
It is also a recipe for several other unpleasant problems with your ac like dirty sock syndrome.
When problems occur this condensation can form a block of ice around the coil causing it to freeze.
Moisture that is condensed by the cooling process freezes due to the coil s low temperature before it can drain away creating the ice you see on your cooling coils.
This ice acts as an insulator preventing the heat transfer that creates cooling.
