Why Loud HVAC Noises Should Never Be Ignored
In order to keep your James Island, South Carolina, home comfortable, your HVAC system will make noise as it powers on and off. You may also hear the gentle sound of air flowing through the ductwork. Aside from these expected noises, if you hear unusual sounds coming from your HVAC system, it may be an indication that there are problems with your ductwork system. Let’s take a look at a few specific HVAC noises that should never be ignored.
If you hear grinding or higher pitch squealing noises coming from your HVAC system, it is likely that there are problems with the moving parts in your system. This could be a lack of lubrication, a broken or worn belt, or loose or damaged bearings. While these issues may seem minimal, if left unaddressed, they could lead to a failure of the motor.
Rattling noises are typically a sign that parts in your system have come loose and are freely circulating around your system. The most likely culprit behind this are bearings that have become dislodged. A major thing that could also be the problem is issues with the circulation of the fan. In either case, failing to address it, could lead to components becoming damaged from the loose parts and a possible shut down of your fan system, which can lead to a major emergency repair.
Hissing noises are often a signal of a dangerous situation that will warrant an emergency call to your HVAC technician. Hissing that is coming from your outdoor unit is a sign that there is coolant leaking from your system. This can be dangerous and you should never attempt to repair this yourself. If you hear hissing noises coming from inside your home, it could be a sign of leaking ductwork. This specific issue can cause your system to work harder than it should, leading to lower efficiency.
If you hear the noises above, or any other loud noises coming from your HVAC system, contact M&B Heating and Air at 843-628-1775 today to schedule your repair service.
