Is My Furnace Running Inefficiently If It Makes a Lot of Noise?

There is so much focus on energy efficiency these days; it feels good when we do the right thing to use less energy. Not only is it good for the planet, but it’s also really good for our utility bills. But if your furnace is running a little louder than usual, should you be concerned about your energy efficiency dropping? Let’s take a look:

Noises and Your Furnace

When your furnace is making new and strange noises, it can be concerning if not alarming. The noises can range from humming or vibrating to scraping, squealing, or banging. There are a number of reasons for each of these noises. Some of these include:

  • Broken blower wheel
  • Blower wheel out of balance
  • Bad or damaged fan motor
  • A clog in the ductwork, loose ductwork, or gaps in the ducts
  • A dirty air filter
  • Dirty burners

Noises and Your Energy Efficiency

Sometimes noises can be something minor and easy to fix, such as a dirty filter, but often, if you hear loud furnace noises, it’s a sign of a bigger problem. When your furnace has an issue that is causing loud noises, even if it hasn’t impacted the temperature in your house yet, it is going to impact your energy efficiency.

One key factor in an efficient furnace is that it is running in peak performance. When it’s not, it’s going to have to work harder to do the same job, which results in excessive energy use.

Whenever you hear noises in your furnace or heating system, don’t ignore them. Calling for service will ensure consistent temperature in your home, potentially prevent even bigger and more costly repairs down the road, and it will get your furnace functioning efficiently again.
