Like any other piece of equipment sometimes your air conditioner has issues and does things it is not supposed to do – like ice up. I think we can all agree that we would prefer for our air conditioner to leave ALL the ice making to that other piece of equipment called an ice maker.
Sometimes when a homeowner discovers that their unit is not cooling because it is covered in ice they decide to turn it off, let the ice thaw (this takes a LONG TIME) and then turn it on again. This is not a good idea or a fix-it-yourself issue. While you may get the ice to thaw you will not be able to fix the underlying problem which caused the ice in the first place.
Some of the reasons you’re a/c may ice up are:
Low Refrigerant – If there is a leak or just not enough refrigerant in the line to begin with it can cause a pressure drop in the evaporator coil (in an indoor unit), this will cause moisture in the air to freeze and accumulate in the coils.
Clogged Air Filter – Replacing a clogged air filter is probably one of the most common air conditioning repairs. In this particular case the clog causes an insufficient flow of air over the coils and reduces their temperature to below freezing – the condensation will then freeze and voila – you have ice. Just not the kind you like.
Outside Temperature – If the outdoor temperature drops below 60 F it can cause you’re A/C to not operate properly and freeze. When it starts getting cooler at night, just turn you’re a/c off and maybe enjoy sleeping with a window cracked.
