  • Check thermostat to ensure your cooling and heating system maintains at a reasonable and comfortable level. You can reduce power bills by investing in digital thermostats to keep their homes warm in the winter and cool in the summer, and even kick on at specific times to lower energy use.

Belleville HVAC companies like Weis note that poorly-functioning equipment reduces a systems' life expectancy. Also check all of the system's controls and oil/gas connections.
