When your HVAC unit begins making noises, this can be an inconvenience to yourself and house guests. Minor noises and quiet hums are normal, but strange sounds could be a sign that your HVAC system needs a tuneup. Here are three noises that suggest your HVAC system in Surf City, NC, needs professional service:

Humming Noises

Loud humming and clanking could indicate a loose blower motor fan, pipes, blades or a number of other problems. If you don’t address these noises quickly, they could pose a serious threat to your system’s health and the quality of the air it’s producing. Therefore, it’s vital to schedule an HVAC repair right away.

Rattling Noises

Rattling noises within your HVAC system can mean a variety of things. If the rattling is coming from the outdoor unit, this could be a sign of debris in the system. Although the unit’s grate will protect it from larger objects, it’s still possible for smaller particles to make their way inside.

When this happens, turn off the unit and shut off the power. Remove any debris and inspect your unit for damage. If the rattling continues, the problem may be internal. Call your HVAC service technician for more extensive repairs.

Hissing Noises

When you hear a hissing noise coming from your unit, this likely means there’s an air leak in it. If you hear this noise coming from your walls, this could mean your ducts are leaking. If you’re hearing a light hissing noise, this could be a sign that the problem is in your air vents.

A gap can be created in the seal if your filter is the wrong size or isn’t installed correctly. Instead of being pulled through the filter, air is squeezing past or around it. This is a simpler fix that can be resolved with a properly sized and correctly installed filter that eliminates gaps in the system.

HVAC Maintenance Matters

If you’re hearing any questionable noises coming from your HVAC system, this likely means your system isn’t running efficiently and is costing you money. Regular HVAC maintenance can resolve any problems you might be having and will get your unit running in top shape.
