Your home should be a place of comfort—not a concert of mysterious clanks, hums, and bangs. But when your HVAC or plumbing system starts making noise, it’s usually a sign that something needs attention.
At Crisafulli Bros., we help homeowners throughout the Capital Region, Hudson Valley and North Country keep their systems running smoothly—and quietly.
Here’s a guide to the most common noises you might hear and what they could mean:
Common HVAC & Plumbing Noises (And What They Might Mean)
1. Rattling
Sounds like: Loose change in a dryer
Possible causes:
- Loose screws or bolts
- Damaged fan blades
- Debris in the vents
- Unsecured ductwork
Action: Rattling can escalate into major wear and tear. It’s best to have a technician check it out before parts loosen further.
2. Squealing or Screeching
Sounds like: Nails on a chalkboard (ouch!)
Possible causes:
- Worn-out fan belts
- Failing motor bearings
- High-pressure flow in pipes
Action: If it’s your HVAC, the belt may need replacing. If it’s your plumbing, it could be a pressure or valve issue.
3. Banging or Popping
Sounds like: Someone slamming a cabinet
Possible causes:
- Expanding or contracting air ducts
- Dirty furnace burners
- Ignition delay in gas systems
Action: This one can be tricky. While some duct noise is normal, sudden bangs could mean ignition issues, which need a professional.
4. Hissing
Sounds like: Air escaping from a balloon
Possible causes:
- Refrigerant leak in AC system
- Leaking air duct
- High water pressure escaping through a valve
Action: A hissing HVAC system could be losing efficiency (and costing you money). If refrigerant is involved, it’s especially urgent to call a pro.
5. Gurgling
Sounds like: A percolating coffee pot
Possible causes:
- Air trapped in plumbing lines
- Slow-draining pipes
- Sediment in water heater
Action: Gurgling plumbing is often caused by improper venting or buildup. Don’t ignore it—it could be a sign of a brewing blockage.
