Problem with Florida AC unit and wife is 9 months pregnant - need suggestions

Heard a "woosh' sound and the AC unit shut down. Breakers look fine. I dont have any idea what else to check and its 85 degrees outside and wife is due to give birth anytime so any suggestions are VERY welcome. I dont know my way around this and will likely call an expert but would sure like to try and fix it myself if possible. Are there any built in shut-offs I should check?

(I am in a condo and everything is only 4 years old...)

"Woosh" makes me think it may have lost its charge. Other then checking to make sure the unit has power with a meter (240 volts) and the contactor is pulling in sending power to the compressor, that is all I can suggest.

What kind of system is it? Air handler and heat pump? Air handler and standard A/C condenser? Mini Split? Make and model numbers will help out the pros when they swing by.

Hmm......To me "Woosh" sounds like the silence you hear when a fan shuts down.
"WhooshHissssssss" could be a refrigerant leak.

Really though, more info would be helpful.
Answer Tolyn's questions about what you have and what it is all doing and we might be able to help.

Whoosh is often the sound that a heat pump makes when power is removed.

A common cause for this is a float switch tripping.
Many systems have a float switch in the secondary pan under the unit. Some have a float switch in the primary pan as well. Geothermal units often have a spade connector that shorts to ground when the primary pan overfills.

You might check for a full secondary or primary pan.

Post the make and model of your unit for more assistance.
