It’s important to pay attention to the sounds that your HVAC system makes.
You want to know how your HVAC system is supposed to sound when it’s operating correctly.
You also want to be able to tell if your HVAC system is making strange noises that it is not supposed to be making. These noises sometimes can be extremely irritating, but don’t ever choose to ignore the sounds! A soft humming noise is usually a common sound that an HVAC system should be making, and the sound of the air moving through the HVAC vents. If there is a loud humming though, you might be having some sort of issue with a circuit breaker being overloaded or loose wiring somewhere in your system. If you start hearing rattling noises, it could be a number of things. You might have loose debris moving around in your system. You will need to shut off your HVAC system power and check to see if you can find the debris. You will want to make sure there is no damage to the inner workings of your HVAC system as well. If you are not able to find the source of the debris, it’s best to have an HVAC professional come in to fix the issue for you. If you hear any hissing sounds, there’s a good chance you have a rip in your ductwork or the seal is compromised. You will want to call an HVAC professional to have your ductwork resealed if this is the case. If you hear clicking, it could be the capacitor in your system is failing. If you hear a whistling noise, it could be a refrigerant leak. For most of these issues, it’s important to get a hold of HVAC professionals for assistance.
