The answer to 'heat pump high energy bills' is that there are several common causes, including improper sizing, lack of maintenance, and inefficient operation. Symptoms may include the heat pump running excessively, uneven heating/cooling, and higher than expected energy bills. Solutions can include adjusting thermostat settings, cleaning the air filters, and having a professional inspect and tune-up the system.
If the heat pump is old, inefficient, or not properly matched to the home, it may be time to consider replacing it with a more energy-efficient model. This is a job best left to a qualified HVAC technician, as they can properly size and install the new system.
