Every house is full of its own particular sounds, from ice makers kicking out ice to creaking doors and stairs. When it comes to HVAC equipment, there are also a range of noises you can expect to hear. After all, HVAC systems are powerful, so it’s natural that they generate sound as they operate.
There are some sounds, however, that shouldn’t be ignored because they can indicate problems may be on the way. It can be difficult to know the difference between normal noise and sounds that are troublesome, but these tips can help.
Under normal conditions, your system may hum, buzz, or whir as it operates. This sound may be a bit louder when it kicks in, but for the most part it’s like a background noise in your home. Get to know the typical sounds your system makes by paying attention to it as it operates on a regular basis. This simple step will help you identify changes in how your system operates.
While anything different coming from your HVAC should get your attention, there are certain noises that warrant immediate attention. For instance, a screeching or squealing sounds are never normal. If you hear this type of noise, then you should call an HVAC professional as soon as possible.
Rattling is another sound that shouldn’t be ignored. This type of noise can indicate a range of issues, including a problem with your fan. Unfortunately, operating your system with a fan issue can lead to more serious and expensive issues. If you hear a rattle during any phase of operation, then you should immediately call an HVAC professional.
Another sound you may hear is the sound of air moving through your vents, especially near the vent or the area where you change your filter. This is a faint, steady sound from the air moving through the system. What’s not normal is a hissing sound, which could indicate improperly sealed duct work or even a coolant leak.
If your system is a bit older, then it may be more noisy. That’s common and may not always indicate a problem, which is why it’s important to get familiar with what’s normal for your system. Essentially, anything that’s different should be watched, especially if it’s accompanied with changes in performance.
