What action can help to improve the efficiency of your HVAC system?

Using a programmable or smart thermostat is an effective way to improve the efficiency of an HVAC system. These types of thermostats allow users to set specific schedules for heating and cooling, which can significantly reduce energy consumption. For instance, a programmable thermostat can automatically adjust the temperature when residents are away from home or during the night when lower temperatures are preferred. This prevents the system from working harder than necessary during times when heating or cooling is not needed, leading to lower energy bills and prolonged equipment life.

Additionally, smart thermostats offer advanced features such as learning capabilities and remote control, which further enhance energy efficiency. They can optimize temperature settings based on user habits and preferences, making it easier to maintain comfort while minimizing energy use.

Other options such as regularly adjusting the thermostat settings may lead to inefficiency because constant manual changes can cause the HVAC system to work harder than required. Leaving windows open during cooling seasons can introduce heat and humidity into the home, negating the efficiency gains of an air conditioning system. Lastly, limiting servicing to just summer can result in poorly maintained equipment, as regular maintenance is crucial to keep the system operating efficiently year-round.
