Ominous HVAC noises
Most of the sounds home electronics make aren't a cause for concern. But if an HVAC system (heating, ventilation, and air conditioning) sounds drastically different from the usual low-key hum, it's time to have it checked by professionals. Those ominous HVAC noises can be an indicator of more significant issues, so pay attention to them. Here are some sounds an air conditioner can make and what they might mean.
Hissing
A subtle hissing sound is typical with some AC systems. But if at the same time, the unit isn't as effective at cooling the air as it was before, this could be an issue. The hissing sound often results from the air going through the vents. There are a few reasons why this might occur: using the wrong size filters, leaking ducts, a clogged filter, internal valve issues, etc. Whatever the reason, call a technician who can find the root of the problem and fix it as soon as possible.
Screeching and squealing
If an AC is screeching, it's time to repair it. These noises are often signs of component issues such as a faulty motor belt or a wobbly fan blade. Sometimes all it takes to fix this problem is a lubricant.
But before grabbing a can of oil from the garage, know that there is a special kind of lubricant that professional HVAC technicians use. Furthermore, a worn-out belt can break, causing even more damage and increasing the repair costs. So the moment it starts the squealing noise, don't hesitate to call a professional.
Thwapping
Fortunately, the thwapping noise you hear coming from the HVAC device isn't always an indicator of a serious issue. Most often, it's simply something stuck in the fan blades. However, if it isn't removed, the object can cause more damage.
Buzzing
Although buzzing is a standard HVAC system sound, if it lasts too long, there might be a malfunction. Additionally, something could be wrong with one of the electrical components. Other times, it's only a loose part. Have it checked before the problem worsens.
Taking care of your HVAC system
HVAC systems are expensive, so be sure to take steps to prolong the device's usefulness. First, you need to clean the system before every cooling or heating season. Next, regular checkups will alert you to potential problems and prevent those issues from damaging the system even more. You should also check the filters. Occasionally, they might be clogged or dirty, which changes the airflow and puts stress on the motor.
Finally, try not to overuse the HVAC system. If it doesn't have to be in operation continuously, give it an occasional break and turn it off to extend its lifespan.
Final thoughts
Timely maintenance and repair will ensure your HVAC system serves for years to come. There are a couple of things that will help keep the system running efficiently between professional HVAC company checkups, but pay attention to any ominous noises. These can be telltale signs of serious issues. If you notice them, call a technician right away.
