Answers to Common Questions

  • What Does a Thermostat Do?

    Thermostats turn on your furnace or air conditioning system until the temperature you set is reached. Once the desired temperature is met, the thermostat will turn the HVAC system off.

  • What Does a Programmable Thermostat Do?

    Programmable thermostats automatically change the thermostat’s set temperature between comfort levels and energy saving levels at specified times, depending on the programs you set up. Typically, programmable thermostats can be used to replace most conventional thermostats.

  • Is It Possible to Install a Thermostat on My Own?

    Yes; however, unless you are an experienced technician, we do not recommend it. The process involves knowledge of the way around your circuit box, and having to remove your existing thermostat. It also involves handling wiring, which can be dangerous and should be handled by a trained professional.
