Keeping You Comfortable Since 1967

Making sure that your HVAC system is functioning properly is vital to maintaining the comfort in your Jacksonville, Florida, home. Over the years, your HVAC system will begin to show signs of wear and tear. You should learn to pay attention to your system, especially if you don’t have a preventive maintenance plan so that serious issues don’t develop. Here are four HVAC noises that should always be investigated:


While a rattling furnace can be distracting, it is also a sign that there is probably a loose part in your system. Bearings can come loose, rattle around the system, and damage other parts if not addressed. This type of noise can also signify worn parts or something disconnected in the motor, which is likely if it becomes louder after it starts running.


Another possible sign of damaged or weak bearings is squealing. Squealing can also occur when the parts in the motor become misaligned. If the problem is in the motor, the noise will most likely occur when the system starts up. Call an HVAC professional if you hear this sound.


Loud, booming noises can be scary, especially when coming from your furnace. Booms are often associated with gas buildup, and if they go unchecked, they can result in a cracked heat exchanger, which can lead to an expensive repair and possibly even cause severe damage to the furnace.


Your furnace may make a slight humming noise when it turns on. However, if the sound is more like hissing than humming, it could mean there’s a problem. Hissing is often a signal of leaking, either in your ductwork or in other components.

Don’t let a minor problem become a major one. If you hear any of these noises coming from your HVAC system, contact our professionals at Abaco Air Experts at (904) 268-3800 to schedule your repair appointment.
