No matter how new or old your HVAC unit is, you should never assume that it will be free of problems. When it is working efficiently, your HVAC system should be relatively quiet. Once you start to hear strange sounds that should tell you that something is wrong. Though different strange noises are indicative of problems in various areas of the HVAC system. In general, it’s always a good idea to look at strange noises as a warning sign. Contact Stahl Plumbing about those unusual sounds. If you have those weird noises checked out immediately, you can avoid more serious and much more expensive problems.
Possible Problems Related to Rattling Noises
If you’re hearing rattling sounds, the most likely place where the rattle is occurring is in the unit’s motor or blower assembly unit. A loose component in either place could be the cause. The problem may not seem like a big deal. If you continue to use your HVAC unit in spite of the noise, the loose part will eventually break off entirely. When that happens, the rattling will turn into loud banging.
The Reasons You May be Hearing Squeaking or Squealing Sounds
Your HVAC unit shouldn’t be making strange squealing or squeaking sounds. If it does, there’s a good likelihood that you have a problem with the fan belt. If you continue to use your HVAC system, the fan belt will eventually break. Once it breaks, the motor won’t turn at al anymore. If your blower component of your motor has a port for oil, you may resolve the noise problem by adding oil. The ordinary household doesn’t work for HVAC motors. Unless you know what oil to use, you should wait for the HVAC repair service to fill the port for you.
Excessively Loud Banging and Clanking Sounds
When you hear annoying banging and clanking noises, something is awry in the motor or blower assembly unit. By the time your system is this noisy, it is safe to assume that something is broken. The problem will keep getting worse until you have a professional HVAC service technician assess the problem.
Hissing and Clicking Sounds
If you hear a hissing sound coming from your HVAC system, that is a telltale sign that your system is losing refrigerant because there is a leak somewhere. The cooling part of your HVAC system won’t cool your home if it doesn’t have enough refrigerant.
Clicking sounds are often a warning sign of a potentially dangerous electrical problem. Turn your system off immediately and call our 24/7 Emergency Services Hotline.
