Depending on how old our equipment is, or how often we have it checked by a professional, finding out our AC units are loud and noisy might mean that something is not working properly. Even the slightest sound shouldn’t be ignored, as it could help us avoid having to completely replace our air conditioning. These are some of the most common noises that AC units tend to make after time, and the reason why they are making such noises. If you have heard anything like this, make sure to give us a call and we’ll be happy to inspect your equipment.
Rattling noises are some of the most common noises we are likely to hear coming from our AC and ventilation units, especially those that are installed outside our house. Most of the times, this type of noise is caused by something falling into the vents, like leaves, sticks, tiny rocks, and other outdoor debris. Another simple cause of a rattling noise could be that a component of our unit has become loose, including its bolts, screws, and fasteners.
Another common type of noise that we might hear coming from our AC unit is a popping sound, which can be coming from our ductwork and not the unit itself. This is a common noise that starts becoming more usual when our ductwork starts to age, and we should have the installation inspected by a professional to make sure nothing in there is faulty or damaged. In order to avoid having popping noises coming from our ductwork, we should make sure we are giving it the proper maintenance regularly.
When we don’t give our ductwork the proper maintenance, noises coming from the installation may become a constant problem. Hissing sounds or whistling noises tend to be another common problem that comes from faulty or damaged ductwork. However, this kind of sounds could be coming from our AC unit, too, and it might be because of a refrigerant leak. If this is the case, we must make sure we get an HVAC professional to handle it, or we could end up damaging our unit more than it was, turning what could be a simple issue into a more complicated problem.
Last but not least, we have one of the most dreaded noises by any responsible homeowner, which is grinding noises. Having our AC unit making loud and annoying grinding noises should never be taken lightly, as it might be coming from one of the fan motors. This type of noise indicates they are not working properly, whether because they are damaged or completely broken. If we hear a grinding noise, don’t hesitate and have an HVAC professional inspect your unit, as we might need to replace either the fans or the entire unit.
