If your energy bills have been higher than usual and you can’t pinpoint the reason why, it’s possible that your furnace may be to blame. While furnaces are essential for keeping homes warm during winter, they can also be one of the biggest energy offenders when it comes to home heating. If your furnace is old or inefficient, it may be time for an upgrade. A new, efficient furnace can not only help lower your energy bills but also improve the comfort of your home. Talk to a local heating and cooling contractor to learn more about whether a new furnace is right for you.
