A noisy residential HVAC system can be a constant nuisance, as well as a sign that there’s something wrong with your system. When you hear something unusual, it’s important to understand what’s causing it so you can seek repairs, if necessary. Here are a few common sounds your HVAC system might make. 

The Meaning of Common HVAC Noises

1. Booming

Loud booms can be disconcerting, and whether they happen one time or frequently, they need to be investigated. In some cases, it’s your ductwork contracting and expanding from the heat; other times, the airflow may be too hard. In the worst cases, rodents or debris may be jumbling around, which warrants a cleaning and inspection. If you notice the noises coming from your furnace, you may have combustion or ignition issues that require assistance from a residential HVAC professional.

2. Shrieking

Shrieking noises can also be alarming and are most often tied to your ductwork. If there are any cracks or small houses where the pieces connect, air will whistle or shriek as it passes through. These leaks cause your system to work overtime, in turn, raising utility bills. If you can see your ductwork, look for perforations; if it’s in the ceiling, have a residential HVAC contractor take a look.

3. Rumbling

Rumbling noises from your furnace or air conditioning unit are often related to breaking or broken parts. The broken pieces might vibrate or clank around inside your unit. It’s impossible to tell without taking a closer look, and a professional is your best bet for diagnosing and repairing the issue.
