The answer to 'mini split high energy bills' is that there are several common causes that can lead to high energy usage with a mini split system, including improper sizing, poor installation, lack of maintenance, and inefficient settings. Symptoms may include the system running constantly, inconsistent temperatures, and high monthly bills.
To address high energy bills with a mini split, you'll want to first check the system sizing to ensure it's properly matched to your home's heating and cooling needs. Improper sizing can cause the system to work harder than necessary. Next, inspect the installation to make sure all components are properly connected and the refrigerant charge is correct.
