AC Acting Poorly? Check These Things:

On a majority of our air conditioning repair calls, it turns out the problem is simple and could have been remedied easily by our customer.

You should make sure that your thermostat is in "On" mode, set to "Cool" and the desired room temperature is set cooler than the current ambient temperature.
Assure that your circuit breaker is "ON" for your cooling system.
Ensure that your "SYSTEM SWITCH" is set to "ON". This switch typically is a toggled dial-plate that may have a RED casing.
When your AC thermostat was out of commission or the system power was shut down, after turning the system back on give it a few minutes; many AC systems have a time-delay function on startup.
If your system is blowing cool air, but not cooling as well as it should, check your outdoor unit to ensure there is nothing blocking airflow through the outdoor coil.
