We typically associate high energy bills with the summer months when air conditioners are running at full blast. However, cold winter temperatures can cause heating systems to work just as hard. Since heating and cooling can account for nearly half of your electric bill, you may notice a spike in energy use in the coming months as the region settles into winter.

If you think an efficient HVAC system will protect you from higher energy bills, think again. Even the most efficient systems consume more energy during extreme weather conditions.

For example, even if you set your thermostat to the recommended 69 F in the winter, when it is 19 F outside, your system has to work hard to make up that 50-degree difference. With your heater working harder and cycling on and off more often, your energy use will be much higher. This means your bill will be higher.

Space heaters can also raise electric bills. Use them strategically to keep the room you’re in warm, and turn down your furnace thermostat to accommodate the additional electric use.

To manage your energy costs this winter, seal windows and doors, use heavy curtains, and maintain your HVAC system for efficiency. Slightly lowering your thermostat when you’re not home can also help. While winter increases energy use, small adjustments can make a big difference in reducing your electric bill.
