Are you noticing spooky noises coming from your HVAC unit? With Halloween right around the corner, these noises could seem weirdly coincidental. Don’t worry – your house isn’t haunted. More than likely, your HVAC system is just trying to alert you of some problems it may be having. Here are the top 3 spooky noises coming from your HVAC unit you should never ignore.

1. Rattling

A rattling noise could mean nothing, or it could mean something. That being said, you never want to ignore this sound coming from your HVAC unit. There are typically two reasons for rattling noises inside your furnace. A rattling noise may indicate the following issues:

– A Loose Panel or a Loose Screw:

A loose panel or a loose screw in your HVAC unit is usually an easy fix. While it’s something you want to have checked out soon, it’s typically not something that puts you or your family at risk. On the contrary, it could be a much more dangerous issue.

– A Leak or Crack In Your Heat Exchanger:

This is very dangerous if not addressed quickly. Faulty heat exchangers can end up leaking carbon monoxide into your home, which can be deadly. Whether it’s just a loose panel or your heat exchanger, it’s better to be safe than sorry. That being said, if you hear this noise, contact your local HVAC professionals right away.

According to the EPA, one of the ways you can reduce exposure to carbon monoxide is by having a trained professional inspect, clean and tune-up your HVAC systems annually.

2. Booming

A loud boom that sounds similar to that of a gunshot can be scary and alarming. A booming sound is typically an indication that there is gas build-up in the system. This noise should never be ignored because it could eventually lead to your heat exchanger cracking. Once the heat exchanger cracks, it could completely burn out the furnace. Not only can be this be inconvenient to deal with (especially in the winter when you rely on your furnace the most), but it can also lead to expensive repairs or replacement. The sooner you address the problem, the better for your overall comfort – in both your home and in your wallet.

3. Whining or Squealing

A whining or squealing noise is likely not an animal like you may have thought, but it could still be spooky. If you hear this noise coming from your HVAC unit, it’s likely your blower belt. Over time, it can experience some wear and tear, causing it to misalign or loosen. We recommend you schedule your annual maintenance and address this at your next appointment. You may find that your blower belt just needs some lubrication, or you may find there is a more serious issue at hand. Either way, your HVAC technician will be able to help you resolve the problem.
