Heating, cooling, and water systems often account for the largest portion of a home’s energy use. Efficient systems improve comfort, reduce costs, and help maintain healthy indoor air quality. Poorly maintained systems can exacerbate indoor pollutants or safety hazards, while efficient systems contribute to lower emissions and reduced environmental impact.
What residents can do:
- Replace HVAC filters regularly
- Adjust thermostat settings seasonally
- Set water heater temperature to 120°F
- Consider programmable or smart thermostats
Professional upgrades:
- Install high-efficiency HVAC or water heating systems
- Balance airflow and integrate with ventilation
- Perform diagnostics and system optimization
