Energy monitoring is the process of tracking and analyzing energy use across HVAC systems, water heaters, and other building loads. Smart meters, home energy management systems, and equipment sensors provide real-time data on consumption patterns. By reviewing this data, homeowners and facility managers can spot inefficiencies, reduce waste, and prioritize upgrades that lower utility costs.

Monitoring reveals HVAC and water-heating energy trends.
A family installs a smart energy monitor and discovers their HVAC runtime spikes in the afternoon and their water heater cycles overnight, prompting schedule adjustments that lower bills.
Review monitoring data monthly to catch unusual spikes that may signal HVAC issues or water heater inefficiencies.
“Review monitoring data monthly to catch unusual spikes that may signal HVAC issues or water heater inefficiencies.”
IoT-enabled meters make real-time energy tracking accessible for homes and small businesses.
Do I need a smart meter for energy monitoring?
Not always. Whole-home monitors or smart HVAC systems can track usage without a utility smart meter.
Can energy monitoring reduce bills by itself?
It reduces bills when you act on the insights, such as adjusting schedules or fixing inefficiencies.
Is energy monitoring useful for water heaters?
Yes. It helps spot high runtimes, inefficient cycling, or opportunities for upgrades.
