3 Common HVAC Noises & What They Mean, Stonington, Connecticut

While they have some unique sounds of their own, today’s HVAC systems are quieter than ever. When they develop loud or annoying sounds, it’s important to investigate right away. Below are some of the most common sounds these units are prone to make and what you can do to resolve it.

What You Should Do About These 3 Common HVAC Noises

1. Rattling

A rattling noise can come from either your HVAC’s inside or outside unit. Typically, when it is an external issue, it will be due to some sort of debris, and you can often easily remove it by turning off the power to the system and removing it. However, if you notice the debris caused any damage to the compressor, fan, or condenser coils, call a technician. Also, when the sound is coming from the furnace or another internal component, you should call a contractor from the start, as loose parts or other obstacles in this region can be more difficult to locate and repair.

2. Whistling

HVACProbably one of the most annoying sounds your HVAC could start making is a high-pitched whistle. When this occurs, it’s usually because the system is not getting enough air through the vents because something is blocking or restricting the airflow. This can be due to several issues, but the most common ones are dirty air filters, blocked return vents, closed or dirty dampers, and having too many doors closed inside of your home. However, if you rectify each of these problems and the whistling persists, you might have a more serious issue on your hands, like leaky ducts or a lack of return inlets, which will require you to contact a contractor immediately. 

Banging

Usually, a banging sound is one of the clearest signs that you have a broken or loose part inside of the air conditioning compressor. While this can sometimes be a simple fix, turn your system off right away when this type of noise arises, and call a contractor to repair it before turning it back on. Leaving it running could cause additional damage.
