The answer to 'why is my condenser high energy bills' is that there are several common causes, including a dirty or clogged air filter, low refrigerant levels, a malfunctioning compressor, or an oversized system. These issues can lead to the condenser working harder and using more energy to cool your home, resulting in higher energy bills.
Some common symptoms of these problems include the condenser running constantly, the air coming from the vents feeling warm, and the system not cooling your home effectively. Solutions can range from simple DIY maintenance like replacing the air filter, to more complex repairs that require a professional HVAC technician, such as recharging the refrigerant or replacing the compressor.
