Your HVAC system is designed to run quietly in the background, providing your home with comfort without being too noticeable. The moment it begins to make noises, you know that something has gone wrong. Learn about the most common noises faulty HVAC systems make and how to properly address them in today’s post.
Hissing Noises
Loud hisses are a sure sign of pressurized air escaping from an unseen point. If you can follow the sound and determine its location, you can find the areas where the air is escaping your system.
Your ducts are the most prone to leakages and can be too complex for a DIY fix. If you suspect any escaping air within your ductwork, contact an HVAC professional right away.
Slight hissing noises may indicate an issue with your filters instead of the ductwork. This simply means that air moves around the filter in the vents instead of going through it. Oftentimes, this is caused by improper placement or size of the filter and can easily be fixed by setting it correctly or replacing it with a properly sized filter to remove the gaps that cause the hissing.
Rattling Noises
Rattling noises can occur in the outdoor unit or the indoor unit. There are a lot of things that can get inside the outdoor unit of your air conditioner. Larger pieces of debris are usually filtered out by the protective grating, however, pebbles, twigs and other smaller items may still find their way inside and cause the rattling noises. If this is the case, turn off your system and remove any visible debris. If the coils have become damaged, call a professional HVAC technician immediately.
If the rattling noises are coming from the indoor unit, the most common culprits are loose components within the HVAC system itself. If any internal part has come off from inside your unit, it’s time to call for professional help.
Clanking Noises
Loud clanking noises are commonly caused by blower fans, pipes or blades coming loose and banging away at each other. These loose parts are a definite symptom of a much bigger problem that’s well beyond any DIY approach and will need the attention of a professional technician.
