There are a couple of different causes for Port Charlotte short cycling. The first possible cause is a malfunctioning thermostat. The thermostat is the brain of the Port Charlotte air conditioning system, and if it starts to experience problems it can transmit conflicting signals to the Port Charlotte air conditioner. The second possible cause of short cycling in your Port Charlotte air conditioner is a damaged compressor. The compressor is a part responsible for circulating refrigerant through your Port Charlotte air conditioning system. This means that the compressor sets the rhythm of the system while it is operating. If the compressor is faulty or damaged, it can throw off that rhythm and cause the system to short cycle. The exact cause, of course, will have to be determined by a professional.
