With the way technology has evolved over the years, it's no wonder that the smart-house movement has gained popularity. As a result, programmable thermostats have taken over the HVAC industry by storm.

By definition, a Programmable Thermostat is a thermostat designed to adjust and change temperature according to a series of programmed settings that take effect throughout the day at different times. Typically, there are four pre-programmed settings that you are able to set-up to help regulate the temperature in your home. The four pre-programmed settings are: Wake, Day, Evening & Sleep. Please see below for a brief overview of each setting:


Not only do programmable thermostats help regulate temperature settings in your home or office, but they can help you save approximately $180 a year in energy costs if programmed and used correctly. According to Energy Star, "The $180 savings assumes a typical, single-family home with a 10-hour daytime setback of 8°F in winter and setup 7°F in summer, and an 8-hour nighttime setback of 8°F in winter and a setup of 4°F in summer."

 Now that you understand what a programmable thermostat is and how it works, it is important to understand what model programmable thermostat best meets your needs. There are three different programmable thermostat models: 7-day model, 5+2-day model and 5-1-1 model. Below is a brief overview of each model:

  • 7-Day Model: This model allows you to create a different temperature schedule for each day of the week. This model offers the most flexibility.
  • 5+2-Day Model: This model allows you to create one temperature schedule for weekdays and another schedule for weekends.
  • 5-1-1 Model: This model allows you to create one schedule for weekdays, one schedule for Saturdays and one schedule for Sundays.

In order to get the most out of your programmable thermostat, there are a few tips that we recommend you follow.

  • Have your programmable thermostat installed by a certified HVAC technician.
  • Follow the pre-programmed settings to help properly program and set-up your thermostat.
  • If your thermostat is battery-operated, remember to change the batteries at least once a year (or when indicated on your programmable thermostat screen).
  • Understand how to program your thermostat when you are away on vacation so you can reduce the energy consumption and costs during that time frame.
