How to Save Energy (and Money) with a Programmable or Smart Thermostat

Heating and cooling account for a large portion of a home’s energy use. A programmable or smart thermostat is one of the simplest upgrades homeowners can make to reduce energy consumption—without sacrificing comfort. When used correctly, these thermostats can lead to noticeable savings on monthly utility bills.

Here are some practical tips to help you get the most out of your programmable or smart thermostat.

1. Set a Schedule That Matches Your Routine

The biggest advantage of programmable and smart thermostats is automation. Instead of heating or cooling your home all day, set the thermostat to adjust based on when you’re home, asleep, or away.

• Lower the temperature in winter (or raise it in summer) while you’re sleeping

• Reduce heating or cooling during work hours or extended absences

• Schedule comfortable temperatures shortly before you return home

• Even small adjustments of 1–2°C can add up to meaningful energy savings over time

2. Avoid Constant Manual Adjustments

Frequently turning the thermostat up and down can cancel out energy-saving benefits. Once your schedule is set, let the thermostat do the work. Smart thermostats learn your habits and fine-tune temperatures automatically, improving efficiency without constant input.

3. Use “Away” and Vacation Modes

If your thermostat has an “away” or vacation setting, use it. These modes prevent your system from running unnecessarily when no one is home—perfect for weekends away or longer trips. Smart thermostats can even detect when the house is empty and adjust automatically.

4. Take Advantage of Smart Features

Many smart thermostats offer features that help maximize efficiency, such as:

• Energy usage reports and monthly summaries

• Weather-based temperature adjustments

• App-based control from your phone or tablet

• Integration with smart home systems

Reviewing energy reports can help you understand patterns and identify opportunities for further savings.

5. Don’t Set Extreme Temperatures

Turning your thermostat to the highest or lowest setting won’t heat or cool your home faster—it only makes your system work harder. Choose moderate, efficient temperature settings to reduce strain on your HVAC system and lower energy costs.

6. Check Placement for Accurate Readings

Thermostats should be installed away from direct sunlight, drafts, windows, or heat-producing appliances. Poor placement can cause inaccurate readings, leading to unnecessary heating or cooling.

7. Pair Your Thermostat with a Well-Maintained Home

A thermostat works best when your home is energy-efficient overall. Make sure:

• Windows and doors are properly sealed

• Insulation is adequate

• HVAC systems are serviced regularly

These steps help your thermostat maintain comfortable temperatures more efficiently.

8. Adjust Seasonally

Update your thermostat settings as seasons change. What works in winter won’t necessarily be efficient in summer. A quick seasonal review ensures your system isn’t working harder than it needs to.

Programmable and smart thermostats are powerful tools for improving energy efficiency, lowering utility bills, and extending the life of your HVAC system. With the right settings and habits, they offer comfort, convenience, and savings—all year long.
