Usually, your heating and cooling system runs quietly, keeping the house comfortable without disturbing you. So if yours has started to make noise, you might wonder if something is wrong. Not all sounds indicate a serious problem, but some do signal the need for repairs, says the team at Dave’s Cooling Heating & Plumbing of Staunton, VA. Here, these HVAC contractors discuss three noises systems make and what they might mean.

3 Common Noises HVAC Systems Make

1. Clanking

If you hear this sound, something inside the unit is either loose or off-balance. For instance, the compressor may have rattled off its mounting, or the blades of the blower fan might be hitting other parts. This problem will escalate if it’s not fixed, so turn the unit off right away and call an HVAC contractor for repairs.

2. Hissing

A hissing noise indicates air is escaping from somewhere it shouldn’t. The problem is usually in the HVAC system’s ducts. Sometimes, it is the result of an improperly installed or wrong size filter. A technician will first check to make sure the filter is the right size, and they’ll likely try replacing it. If that doesn’t fix the problem, the ducts might be leaking.

3. Clicking

While it’s normal to hear a clicking noise when the system starts or shuts down, this sound shouldn’t be constant. If you hear it all the time, the thermostat could be failing or a control might be broken. Ongoing clicking indicates an electrical issue, so it’s crucial to get it fixed right away.
