It may be buildig ice on the indoor coil and outside coil. If ice is found see the "What is freezing up?" Faq. Also if your system is extremely low on freon it may not be cooling at all. If your system does turn out to be low on freon this means your system has a freon leak in it somewhere. The best thing to do is have a service technician come out and check your system.
