As Halloween creeps closer on the Space Coast, the last thing you want is your HVAC system adding eerie sounds to the spooky season. Strange noises coming from your heating or cooling unit can be unsettling, but they often signal specific issues that need attention. At Complete Air & Heat, Inc., we’re here to help you decode those creepy clanks, bangs, and screeches so you know when it’s time to call in the professionals.
Banging or Clanking: The Monster in the Machine
Hearing loud banging or clanking noises from your HVAC system? It’s not a ghost rattling chains—it’s likely a sign of a loose or broken component. This could be a fan blade hitting something inside the unit, a loose motor mount, or even a failing compressor. These issues can worsen over time, potentially leading to costly repairs if ignored. If the banging is persistent, especially when the system starts or stops, it’s time to schedule a professional inspection to prevent further damage.
Screeching or Squealing: A Banshee’s Cry
A high-pitched screech or squeal coming from your HVAC unit might remind you of a banshee’s wail, but it’s often a sign of a worn-out belt or motor bearings. These components can wear down due to age or lack of maintenance, causing friction that produces those unsettling sounds. In some cases, a screech could also indicate a refrigerant leak, which requires immediate attention to avoid system inefficiency or environmental harm.
Hiss or Whistle: Ghostly Air Leaks
A hissing or whistling sound might seem like a ghostly whisper, but it’s typically caused by air escaping from your HVAC system. This could point to a leak in the ductwork, a clogged filter restricting airflow, or even a problem with the system’s pressure balance. While a hissing noise might not seem urgent, it can reduce your system’s efficiency, driving up energy bills and leaving your home less comfortable. A professional can locate and seal leaks or replace filters to keep your system running smoothly.
Rattling or Vibrating: The Poltergeist Effect
Rattling or vibrating noises can feel like a poltergeist shaking your HVAC unit. These sounds often come from loose panels, screws, or debris caught in the system. While a loose screw might seem minor, vibrations can cause parts to wear out faster or lead to more significant damage. If you hear rattling, check the unit for obvious loose parts, but don’t hesitate to call our team if the noise persists.
When to Call the Professionals
While some HVAC noises might have simple fixes, like tightening a screw or replacing a filter, most require expert attention to avoid bigger problems. If you hear persistent or loud noises, notice reduced system performance, or experience uneven heating or cooling, it’s time to call in the pros. At Complete Air & Heat, Inc., our experienced technicians can diagnose and resolve HVAC issues quickly, ensuring your home stays comfortable and your system runs efficiently.
