Daylight Saving Time Checklist: Your HVAC System

Daylight Saving Time Checklist: Your HVAC SystemDaylight saving time (DST) ends November 5, 2017, which means it will be time to change the clocks and your programmable thermostat one hour back. It’s easier to remember how to set it by thinking about springing forward in the spring and falling back in the autumn.

The purpose of the time change was to save energy by reducing the amount of indoor lighting required in the summer. It has proved marginally successful for this purpose. Much greater energy savings have come from more efficient HVAC systems, lighting, stricter building codes and appliances. Efforts to overturn DST have met with resistance because people enjoy longer daylight hours while the weather is comfortable outdoors.

Changing the Thermostat

Some types of programmable thermostats are fairly intuitive, but if yours isn’t, you may need to consult the owner’s manual to reset it. Most manufacturers provide these manuals online if you’ve misplaced yours.

It’s also a good idea to change the batteries for the thermostat when you adjust the time for daylight saving time. Without working batteries, the thermostat won’t be able to turn the HVAC system on. Most programmable thermostat covers are easy to take off by twisting or prying the covers off, or removing a few screws.

Changing the Temperatures

Unlike summer, chances are you’ll want the home warmer during the day and cooler at night. As you prepare to change from DST to standard time, set the thermostat for optimal energy savings.

Turning the temperature down at night helps you sleep better and save energy. While you’re home during the day, a setting of 68 degrees F is comfortable for most. You may also want to increase the daytime temperatures during the weekends when your family is at home.

Adjusting the thermostat for the end of daylight saving time will give you better temperature control for winter. If you need help with this project or haven’t had your system serviced for winter, please contact Roth Heating & Cooling, providing trusted HVAC services for Portland area homeowners.

Our goal is to help educate our customers in the Metro Portland, Oregon area about energy and home comfort issues (specific to HVAC systems).
