Check These Things Before You Call Us:

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.
