What’s That Noise?


Summer can be a noisy time of year, especially if you are in a neighborhood filled with kids on summer break. It is also filled with the sound of air conditioners working hard to keep our homes cool.

These systems have a lot of work on their hands. Temperatures throughout the summer are high so they are going to have to do their best to keep your home cool. It makes sense then that you would want to address any problems in your air conditioner that would make the cooling process harder.

While it is noisy during the summertime, we want to encourage you to listen a little more closely to your AC system while it is running. Picking up on any concerning noises from your AC unit can help you figure out if you need to schedule air conditioner repair in Northfield.

What Does That Noise Mean?

If you hear any of the following sounds from your air conditioner, it means that you should have a technician check out your system to see if it needs repairs.

1. Rattling

Rattling is something of an early warning noise. This is most often created by bolts, screws or other internal components that are beginning to loosen and vibrate in their housing. The sooner you address a rattling noise, the better since this sound will escalate into…

2. Clanging

We get it. Not everyone realizes that rattling sounds are a problem or maybe they forgot to call the technician. But now the rattling noise has been replaced by a clanging. This may be due to the loose part fully coming free and banging or bouncing around in your AC. It is easy to understand that this can cause a lot of additional damage until it is addressed. Call a professional ASAP to get this fixed.

3. Hissing

Hissing sounds aren’t the same as the regular whoosh of air. Hissing is the sound of air escaping your system in a way it isn’t meant to. One cause of this noise may be due to a leak in your ductwork. Another cause however may be refrigerant escaping the refrigerant line.

4. Bubbling

Does it sound like your AC is brewing something? That isn’t normal! There is no water that is “used up” in the cooling process. That bubbling noise is actually another indicator of a leak in the refrigerant line. What you are hearing are the air bubbles that are now present in the liquid refrigerant.

5. Screeching

Arguably the most noticeable sound, screeching or screaming is often annoying enough that homeowners call us without ever reading a blog like this. But, we include this sound just to make sure that you know that, yes, that screeching sound from your AC is not normal. This can denote a loose fan blade that is scraping the metal walls of its housing or may indicate a dry blower motor belt.

If something sounds off with your air conditioner, make sure to reach out to a technician. Even if the issue is resolved easily with a minor adjustment, you are better off having a technician complete the job rather than leaving the issue to escalate.
