Common conclusions
Due to the power outage your AC may have malfunctioned. Call your local utility supplier and inform them about the power outage.
Flip the switch to turn on your AC.
The tripped switch might be the cause of the malfunctioning AC. Flip the switch and the air conditioner should start working properly.
Plug the AC in properly and try to start it again as the issue may have been with the incorrectly plugged in switch.
The damaged wire may be why the AC isn't turning on. Contact a professional to repair the wire or repair it yourself if you have the skills to do so.
The socket in which you plugged in the AC may have overloaded and burned. Change the socket or reconnect the wires properly. You may do so yourself or hire a professional.
Contact the AC's original manufacturer regarding the problem as there may be a fault in the internal circuit.
Open the vents as this may be the reason why the air is not flowing.
First change the settings using the remote as it may be the cause for the air to not blow.
Clean the air filters by removing and washing them as filter's clogged with dirt or other debris won’t allow any air flow.
Contact the original manufacturer or a professional as the problem may be with the motor or a leak in the refrigerant pipe.
First set the temperature properly as it may be the cause for the AC to not cycle properly.
Open all the vents as even one closed vent makes it difficult to cool the area.
You may have to replace your air conditioner with a bigger unit as your currently fitted AC may be of the wrong size for your home.
Contact the original manufacturer or a professional as the problem may be a leak in the refrigerant pipe due to wear and tear due to long time use.
This might be normal as in hot and humid weather,some times water starts leaking as long as it only forms while the unit is working.
Clean the filters as some time water leakage may be caused by the filters. If problem persists, call a professional electrician.
Turn the AC off and contact an electrician as the problem can be caused by a clogged condensate drain line or rust.
