First, don’t panic. This is rather common. Begin by going to your thermostat. Switch the fan setting from “auto” to “on.” This will help to thaw the unit out. You’ll also need to switch it from “cool” to “off.”
The next thing we recommend you do is check your air filter. Is it dirty? If so, you may be lucky in that it was only a clogged air filter! Change the filter out and run your air conditioner normally once it thaws out.
If the filter is clean, you may have another air flow issue such as a collapsed duct run, undersized ducts or even a blower motor on its last leg. Another common issue is a refrigerant leak. This causes a pressure drop in the air around the coil which causes the moisture in the air to freeze which is what you might be seeing on your coil.
Unfortunately, if it’s anything more than a clogged air filter, you will need a certified HVAC technician to inspect the unit and make repairs and possibly add refrigerant back to your system.
