5 HVAC System Sounds You Don't Want to Hear

5 HVAC System Sounds You Don't Want to HearHave you noticed strange noises coming from your HVAC system? Many homeowners understand that unusual smells indicate hidden problems, but it is equally important that you keep your ears open for noise. An out-of-the-ordinary sound just might mean it’s time to call a professional.

Which HVAC sounds are cause for concern?

It’s important to note that some noise can be expected when turning your system on and off. However, most should not be continuously occurring during operation. The following six noises can indicate the need for professional furnace repair or furnace replacement.

1. Squealing or Screeching

Much like in your vehicle, a squealing noise generally points to a worn-out belt. This isn’t necessarily an immediate problem; however, your belt should be replaced before it breaks entirely.

2. Rattling

If you hear rattling coming from your HVAC unit, a small piece of hardware has likely broken loose and is rolling around the system. This can cause damage if not attended to quickly, so you should turn off your system and call a professional ASAP.

3. Clicking

Clicking generally indicates that your HVAC system is having difficulty making an electrical connection.

4. Squeaking

A squeaking noise probably means that something needs to be lubricated. This can be fixed simply by adding some lubricant to the correct unit.

5. Noises from exterior compressor

A hissing noise coming from the exterior compressor might indicate a refrigerant leak. This should be examined by a professional immediately, as loose refrigerant can be harmful to anyone living in your home.

What Should You Do When You Hear Strange HVAC Noises?

If you notice strange noises coming from your furnace or air conditioning unit, you can begin by investigating on your own. If you can’t locate a source, do not hesitate to call a professional. It is always better to locate problems in the early stages than to be surprised by a system breakdown later on. Not only will this save you money, it will save you a major headache.

It is also important to schedule routine HVAC inspections by professionals. Taking the time to properly care for and maintain your system can help keep things operating smoothly.
