The answer to 'air conditioner high energy bills' is that there are several common causes, including an oversized AC unit, poor insulation, air leaks, dirty air filters, and issues with the thermostat or ductwork. Symptoms include the AC running constantly, uneven cooling, and high energy bills. Solutions can include sealing air leaks, upgrading insulation, cleaning or replacing air filters, and having a professional inspect and tune up the HVAC system.
If the high energy bills persist after basic maintenance, it's best to call in an HVAC technician to diagnose and fix any underlying issues. They can check refrigerant levels, inspect the compressor and other components, and make recommendations for improving the system's efficiency.
