If your thermostat has a mercury bulb it has to be level to be accurate. Check and make sure it is level. If the thermostat is level as a heating tech. i would next check the amp. draw through the thermostat so I could make sure the heat anticipator is set properly. This may be more than a home owner wants to tackle.

SOURCE: My A/C is operating outside
With such limited information the following is the most likely problem.
1. The fan outside is running but the compressor is not.
2. The inside air handler blower fan is not working.
3. The system is froze up and not allowing any cold air to come out of the vents.
Hope this helps
