320 views

Leaving the thermostat on at a consistent temperature is generally more efficient than turning it off, especially during extreme weather. This practice can prevent your HVAC system from working harder to reheat or recool your home, leading to energy savings over time. However, for long absences, lowering the thermostat setting rather than turning it off can strike a balance between maintaining efficiency and conserving energy.

FAQs & Answers

  1. Is it better to leave the thermostat on or off when not at home? It's generally better to lower the thermostat setting rather than turning it off completely during absences to maintain efficiency and prevent your HVAC system from working harder later.
  2. How does leaving the thermostat on save energy? Keeping the thermostat at a consistent temperature prevents your HVAC system from using excess energy to reheat or recool your home after temperature extremes.
  3. What thermostat setting is recommended for long absences? Lowering the thermostat to a reduced temperature instead of switching it off helps balance energy savings and system efficiency during long periods away.
