Dealing With High Energy Bills? These Are the Common Causes to Avoid

As temperatures keep dropping and we get closer to the official arrival of winter, some spikes in energy bills are to be expected. But, if your energy bills are significantly higher than average, it could put an unnecessary strain on your life. To make things easier, we’re going to cover the ten most common reasons for high energy bills, so you can avoid them. 

10 Common Causes of High Energy Bills During the Winter 

Tinkering With Your Thermostat 

In most homes, there’s usually a thin line between finding the perfect temperature and sending energy bills through the roof. If you have an outdated or malfunctioning thermostat, finding this balance becomes more challenging and leads to decreased energy efficiency. 

If you don’t have one yet, a programmable or smart thermostat is the best step you can take toward lowering high energy bills related to thermostat troubles.

Automatically setting your thermostat back 7-10 degrees for 8 hours a day (when you’re not home or while you’re sleeping) can save you up to 10% on energy bills. Smart thermostats that can be controlled from anywhere can save you even more, and upgrading your thermostat comes with other added benefits too.  

Poorly Installed or Damaged Insulation 

There’s no point in your HVAC system working hard to heat your home if all the heat is escaping due to poor or damaged insulation. If you feel like you constantly have to run the heat or turn up the thermostat, but your home isn’t warm, or temperatures are uneven, then you might have an insulation problem on your hands. 

Check doors, windows, attics, basements, and other areas that should be well insulated for any drafts or leaks. If drafts or leaks are found, reinsulate right away for energy savings. 

Dirty Filter 

It’s essential to stay on top of regularly changing your furnace filter for many reasons, and one of them is that a dirty filter can lead to higher energy bills. When your filter isn’t changed regularly, it becomes clogged, and your furnace can’t operate as it should, causing it to work harder than it needs to. 

Leaky or Dirty Ductwork 

Since ductwork is usually kept out of sight, it’s often a component of HVAC that homeowners don’t give much thought to. But, your ductwork plays an essential role in the safe and clean heating of your home during the winter. 

If ductwork is damaged or punctured, it can lead to leaks that let out heat. Additionally, dirty ductwork can lead to air circulation, heating, and airflow problems that can also lead to spikes in energy bills. 

Old or Inefficient Furnace 

Another factor that can have a huge impact on energy bills is the condition of your furnace. If your home is operating with an old, outdated, or malfunctioning furnace, you’re sure to experience increases in your energy bills. 

While you might think a furnace repair or replacement is too costly, in the long run, it’ll cost you more to ignore it. Here are some common signs that it’s time for a furnace repair or replacement

Missed Maintenance

From safety to comfort, there are many reasons why proper HVAC maintenance is essential. One of these reasons is that HVAC maintenance helps ensure your system is operating optimally, which leads to better energy efficiency, longevity, and energy savings. 

Holiday Heating 

Winter brings with it some of the most joyous holidays of the year, but if you’re not careful, these holidays can lead to spikes in energy bills. From cooking large meals to kids staying home for winter break and family and friends visiting, there are many ways the holidays can lead to higher energy bills. Remember to be mindful of energy spending during the holidays with energy-saving tips

Dazzling Decor 

Along with the holiday heating mentioned above, the winter holidays also mean decorating both the interior and exterior of homes with lights. Holiday lights bring with them a festive, joyous spirit for all to enjoy, but they can also lead to significantly higher energy bills. 

When decorating your home, always opt for energy-efficient lights and make sure everything is unplugged before you go to sleep for the night. 

Blocked Radiators or Heating Vents 

If you like to rearrange your furniture or change the curtains with the seasons, then you should do a walkthrough of your home to ensure that none of your radiators or heating vents are blocked. 

Covered radiators or blocked heating vents reduce energy efficiency and can also pose a fire hazard. 

Loading Up the Laundry 

Winter generally means cozying up in added layers and blankets, and while that means more warmth and comfort, it also often means more laundry. Now, we’re not saying that you should avoid doing laundry to reduce your energy bills, but being mindful of how often you wash things can be helpful.
