Our Recommendation

Smart thermostats are worth considering if:

  • You do not currently use programmable features
  • You want remote monitoring capability
  • You have an irregular schedule
  • You are interested in energy tracking

They may not be necessary if:

  • You already manage your thermostat efficiently
  • You prefer simple, manual control
  • Your home is already very efficient

Either way, proper HVAC maintenance and a well-set thermostat (smart or not) will provide the biggest efficiency gains.
