Main air conditioning and air-source warm pushes in chilling mode are typically rated on a periodic angles using the periodic energy-efficiency rating (SEER). This is the total periodic chilling outcome in Buts divided by the watt-hours of electricity consumption. Central air Conditioning and Air-source warm pushes must have SEER scores of 13.0 or higher. On Jan 1, 2015, those standards are scheduled to be stiffened. To qualify for the Power Star standard, central warm and air and air-source warm pushes both must have SEER scores of 14.5 for split systems (separate outdoor and indoor components) or 14.0 for packed units

Still trying to understand the above reply to your OP.

The first thing I would check is to go outside and see if compressor inside condenser is running. You should be able to hear it. Check your breaker box as well for a tripped circuit. Beyond that, you should call a dealer tech out to check your system.

Good luck!

Don't delay, in case you are still under a 10 year warranty. If you are, put this issue in writing to carrier to document it in case it takes a bit to resolve.
