4 HVAC Noises and the Problems They Warn You About
A well-maintained HVAC system usually runs quietly, so if you hear sudden and unusual noises then there might be something wrong with your system. Countryside Plumbing and Heating is the top HVAC and plumbing expert in our area, and we suggest researching typical HVAC noises so that you know what they mean. Here are four noises you need to know about:
-
High Pitched Whistling – You need to turn off your cooling system and call a heating and cooling professional the moment you hear high pitched screaming or whistling from your air conditioner. A refrigerant leak is the most probable cause of this sound, and this can damage your air conditioner. There might also be high internal pressure within your compressor, which can be hazardous.
-
Metal Scraping – Shut off your heating and cooling system if you hear this sound to prevent further damage. This sound can indicate that there is a foreign object that’s obstructing the blades of your fan. This is a problem because repeated contact with the object can damage the blades and motors of the fan. When a fan blade is broken or bent, it can damage the tubing and fins on the coil.
-
Clanking or Banging – If you hear rattling, clanking, or banging, then there might be a problem with the motor or blower assembly of your heating and cooling system. The louder the sound, the worse the problem so you need to shut your HVAC off and call a professional for an inspection. Fortunately, a timely repair can usually fix the loose part before it breaks off completely.
-
Hissing – If you hear a loud hiss from your heating and cooling system then your home might have improperly sealed ductwork. The conditioned air that should be circulating around your home is leaking into your walls and wasting you money. On the other hand, a light hiss can mean that you have the wrong size air filter or that the filter is not set right. Air is moving around the filter instead of through it, causing the hiss. You need to call a professional to get a more accurate diagnosis of your problem.
