Thermostat malfunction
The thermostat is like a mini-computer that reads the temperature in the room and compares it with the temperature you set it for. When the temperature in the room matches what you selected on the thermostat, then the A/C unit will turn off—that is IF it is working properly. When there is a problem, it will keep either running (not realizing the room has reached the right temperature) or it will turn off too soon. A certified technician can fix the problem.
Dirty coils
Dirt and air conditioners do not get along well together. The reason for this is air conditioner must have unrestricted airflow to do its job; if dirt clogs up the coils, then air cannot flow smoothly through and problems result.
Compressor
The compressor is one of the most important parts of your A/C unit. Its job is to be sure the refrigerant keeps flowing and it pressurizes the system. When the compressor is not working, you may first hear unusual noises coming from the unit. High-pitched squeaking or squeals or low-pitched rumbling could be indicative of the compressor going bad. Another problem that occurs when compressors go bad is the clutch will cease to operate.
