Is the HVAC system in your New Braunfels, Texas, home making a lot of noise? If so, you’re probably wondering what the sounds mean and whether they’re a cause for concern. Here are some of the most common HVAC sounds that can come from a heating and cooling system:

Squealing

When you hear a squealing noise in your heating system, it could be caused by the furnace blower. It’s an indication that you need to get the housing cleaned out. You shouldn’t try to perform this cleaning yourself, as it involves opening the system. During routine maintenance service, an HVAC service technician can clean the housing and check the blower to make sure it’s working properly.

Grinding

A grinding sound coming from the HVAC system is often more serious than other noises. Therefore, you should take care of it right away. Grinding can indicate the blower motor is failing, either because it has reached the end of its lifespan or you haven’t been keeping up with regular maintenance. Investing in preventive maintenance helps you avoid breakdowns and maximizes the life of your equipment.

Rattling

If your system makes a rattling sound when it starts up, you may have something stuck in one of the air intakes or vents. Young kids are notorious for sticking their toys and other objects down the vents. If you can’t find anything around the vents, you could have an item trapped in your ducts. An HVAC service technician can locate and remove it before it causes further damage. As a result, you’ll avoid costly future repairs.

Banging

A banging sound could mean that one of the components in your system has come loose and is knocking against something else. This noise may also occur if you have a problem with your ductwork. As the walls of the ducts contract and expand, their movement may result in a banging or popping sound. This noise is certainly alarming, especially if the volume is loud. Therefore, it’s best to have it checked out by a professional.
