Wait for the ice to melt off the coil then restart the system.
Indoor ac coil freezing up.
If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation.
This happens because the refrigerant in the evaporator coils can no longer absorb the heat needed for the coils to warm 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.
If it is dirty that is your problem.
Refrigerant temperature plunges into the range below 32 degrees.
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.
Turn the fan switch on the thermostat to on.
Turn it off remove the filter.
It is also a recipe for several other unpleasant problems with your ac like dirty sock syndrome.
If your air conditioner is running low on refrigerant due to a possible leak it can freeze up.
The reason your evaporator coils can freeze is that in addition to cooling the air inside your home air conditioners also dehumidify it.
When problems occur this condensation can form a block of ice around the coil causing it to freeze.
All sorts of mechanical problems and other issues can cause an air conditioner s coils to freeze.
This makes the refrigerant lines and then the coils freeze over.
In the process it also drains a lot of condensation.
A dirty evaporator coil the inside one can cause a lack of airflow across it dropping the temperature and causing your air conditioner to freeze up.
In many cases freezing up ac is simply the result of a poorly configured thermostat.
This can also result from running an ac at a sufficiently low temperature for long enough.
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.
This ice acts as an insulator preventing the heat transfer that creates cooling.
If it leaks the lack of pressure will make it absorb more heat than it should.
Let it run for a couple hours to thaw the coils.
If the filter appears extremely dirty or clogged install a new filter.
The more the refrigerant has to expand the cooler it makes the temperature.
They pull the water out of the air which makes condensation that builds up on the coils.
The evaporator coil is prone to freezing primarily because it transfers heat or evaporates it from the indoor to the outdoor air.
