Noisy HVAC System? 3 Sounds to Never Ignore

January 22, 2022

Keeping your HVAC system running smoothly is vital to the comfort of your Ocala, Florida home. Unfortunately, there may be times when you experience problems with your HVAC system that signal the need for repairs to prevent a minor problem from becoming a major concern. While your HVAC system will emit some normal noises as it runs, there are sounds you should never ignore.

Grinding

Grinding and high-pitched squealing are signals that the moving parts located in your HVAC system are no longer working properly. When parts stop functioning, this indicates a serious problem that needs addressing.

First, turn your system off. Wait a few minutes, and turn it on again. If the noise persists, shut your system down and contact an HVAC service technician. The issue can be as minor as a belt that needs to be replaced or as major as a motor problem.

Rattling

When you hear a rattling noise as your system is running, it’s often a sign that there’s some issue with the fan. This problem is often a simple fix by an HVAC service technician. If left unaddressed, though, it can result in complete shutdown of your system. Continuing to run your system when there’s a fan problem will cause more damage. Therefore, you should shut off the system immediately and call for repair.

Hissing

Hissing noises inside the home or around the outdoor unit of your system often signal there’s a leak somewhere. It can be as simple as leaky ductwork, which lowers the efficiency of the system, or as major as a coolant leaking. Running your system for a short time when hissing occurs is OK. But you should call a service technician immediately to identify and address the problem.

If you notice the smell of rotten eggs anywhere in or around your home, it could signal a gas leak. If this occurs, shut the HVAC system down immediately and call the gas company and your service technician. Vacate the home until you know it’s safe to return.
