It's winter! And that means low temperatures and high heating costs. If you're looking to reduce your energy bills this season without compromising comfort, this guide is for you. We’ll discuss how to make sure your Wilmington home stays cozy without costing you an arm and a leg. With these ideas, it'll be easy to keep cozy all winter long!

Let’s review what temperature to set your thermostat in winter:

  • While you’re home during the day.
  • While sleeping at night.
  • While you’re away.

We’ll also go over how installing a smart thermostat can reduce heating bills, as well as a few of our top energy-saving tips for cold weather.

Our Suggestions for Winter Thermostat Settings

You might be wondering if 70 is a good temperature for the winter. It can be, but it also depends on your comfort level and your goals for energy efficiency. According to the U.S. Department of Energy (DOE), setting your thermostat at 68 is the smartest way to keep heating costs under control.

What Temperature to Set Your Thermostat in Winter During the Day

While Home

The DOE recommends 68 degrees during the day. If you’re feeling too chilly, there are a couple of other ways you can stay comfortable.

  • Set your ceiling fan in reverse when you’re in a room. This redistributes hot air that collects near the ceiling.
  • Choose energy-efficient window treatments, like honeycomb shades or plantation shutters. If your home has old or drafty windows, putting up plastic sheeting or window blankets offers an additional barrier against the cold.
  • Make the most of natural warmth by opening south-facing window treatments during the day. Don’t forget to shut them at night to minimize heat loss.

While Gone

If it dips under 30 degrees, setting your thermostat around 64-65 degrees is a sensible choice while gone. Your furnace won’t be heating a vacant home, but it’ll be easy for the temperature to bounce back when you get back.

You may want to set the thermostat slightly higher if you have a dog, especially a puppy, senior dog, small dog or a dog with short hair. Between 66-67 degrees will keep them comfortable and happy.

What Temperature to Set Your Thermostat in Winter at Night

Keeping your bedroom cool can help you sleep better. The National Sleep Foundation recommends a thermostat setting of 64-65 degrees.

That might seem too cold if you’re used to a warmer temperature. If you’re used to sleeping at 68 degrees, try slowly lowering it over the next few days and sleep with more blankets or thicker pajamas.

Options for You to Manage Energy Bills During Winter

Keeping your thermostat at the right temperature in the winter is a good first step to keeping energy costs low. But there are a few other things you can do to cut your bill.

  • Upgrade your thermostat. Programmable thermostats are inexpensive, but most households don’t have them set up correctly. If yours is constantly on “hold,” you’re missing out on energy savings. While you can program yours, it can be a lengthy process, especially if your schedule fluctuates from day to day. A smart thermostat can get rid of all that work because it can create an energy-efficient heating schedule based on your routine and temperature preferences.

  • Change your furnace air filter regularly. A dirty air filter can cause a lot of problems for your furnace, including making it consume more energy or even causing it to break down. That’s why it’s important to replace yours every month if you use a flat filter. Or every three months if you use a pleated filter. If you have pets or someone in your home suffers from allergies or asthma, you may want to replace your filter more often.
  • Add more insulation. Your home is probably among the 90% in the U.S. that don’t have adequate attic insulation. Homes in northern climates require 16-18", while those in southern climates need 13-14".
  • Install a new furnace. If your HVAC system is nearly 15 years old, it’s time to start thinking about furnace installation. Getting an ENERGY STAR® furnace can keep you comfier while keeping heating costs down. A new heating system is a big investment, but Brandywine Heating & Air helps make it more budget friendly through rebates, special offers and financing for qualified customers.
