Although most air conditioners see their heaviest use during those hot Florida summer months, it is still possible for a central air conditioning system to freeze up. There are a variety of causes for this problem, but before you can diagnose it, you must first thaw the ice.
To thaw an air conditioner unit, turn the entire unit off. Deactivate the breakers so that the circuits do not short out during the thawing process.
WARNING: This is a very important step as water and electrical devices do not mix.
As the air conditioner thaws, water will drip and leak from the unit itself. To prevent the thawing water from making a mess, place a bucket underneath the air conditioning unit. Monitor carefully as the ice melts.
Once the ice has melted, allow the air conditioner unit to dry for 24 hours
