3 Scary Noises Your Furnace Shouldn't Make

Most furnaces make some sort of sound when starting up. This is perfectly normal and to be expected. However, it's not good when a furnace makes bizarre sounds when you least expect it. If you are concerned about some of the scary noises your home heating system has been making lately, keep reading to learn more about sounds that should be reason enough to contact an HVAC professional.

1. Bangs and Booms

Banging and booming sounds are expected if we're talking about the Fourth of July, but not so much when it comes to your furnace. Possible reasons for these furnace noises include:

• A gas buildup in your furnace, which could contribute to a cracked heat exchanger
• Dirty burners, which sometimes delay the process of starting your furnace
• Contracting ducts, which is a problem often remedied by insulating your ducts

Fear not! These are issues an HVAC expert can deal with safely and effectively. With your ducts, it's also a good idea to have them regularly cleaned. An accumulation of dirt and debris has the potential to make a bang and boom sound more noticeable.

2. Rattling Noises

Rattling sounds are another issue often easily correctable. In this instance, the reason for the rattling is usually a loose panel or other parts that need to be tightened up. Just be sure you turn off the power first. If you don't feel comfortable doing anything inside your furnace, contact an HVAC professional. It's best to take care of loose parts as soon as possible to avoid damaging various internal parts of your furnace.

3. Squealing or Screeching

These sounds are certainly eerie when heard. Screeching, squealing, and whistling sounds are often associated with issues with a belt-driven motor. You may also have a blower belt that's damaged. In other cases, these sounds could also mean some parts that normally move inside your furnace need lubrication. Fortunately, a professional HVAC technician can help you with any of these issues.
