What You SHOULD Hear Coming From Your AC

We talk a lot about things you shouldn’t detect from your air conditioner. If you’re picking up on a foul odor, loud and uncomfortable noises, or even the fact that it’s not working at all, then you should call our team for help. These occurrences almost always signal a problem that can and should be fixed by a professional.

However, this blog post isn’t about those noises or smells. In fact, you can probably check back to this blog in a couple of weeks, or even check a previous blog post for some tips on how to detect problems. This week, we’d like to ease your mind and talk about some of the noises your air conditioner should be making.

Just remember, if any of these noises sound a bit louder or more uncomfortable than they should be, then you still should call for help with AC repair in Pine Bluff, AR.

Whooshing of Air From the Vents

When you turn your air conditioner on, you probably expect it to get to work cooling the air in your home. This process doesn’t happen magically, the system needs to actually cool the air inside the system and send it through the ducts of your home to reach the areas where you can feel it. This is done with a blower fan system that sends it on its way.

Fans can make a gentle noise, especially when they’re located far away, but they still make sounds. You should hear the sound of air whooshing through the air vents and into the rooms of your home where you can feel it. If you don’t hear any whooshing, check the vents. If there’s no air coming from them, then the AC is likely either not on or it’s broken.

Creaking Ducts

Air ducts go through drastic temperature changes when you run your air conditioner. They can start at a hot point and be lowered a considerable amount in just a short period of time. This causes the air ducts to expand and contract quickly. Since air ducts are usually constructed out of sheet metal, or some kind of metal, that expansion and contraction can make a noise.

Don’t be alarmed, unless this sound is extremely loud or disconcerting. It’s probably nothing to be worried about.

Clicking On or Off

The capacitors in your air conditioner need to signal to the system when to turn on or off. Every time the temperature jumps above what it’s set to on the thermostat, the system should kick on. This is usually done first with a clicking sound, which is completely normal. Then, the system usually clicks again when it shuts off. If there are multiple clicks (more than two) per cycle, then you should call us to inspect the unit.

The Hum of the Compressor

You’ve probably heard your outdoor AC compressor hum while it cools the inside of your house. This is nothing to be alarmed by. The compressor is the heart of the AC, continuously pressurizing the refrigerant and cooling the air as it cycles. Think of this hum as the heartbeat of your air conditioner, and a signal that it’s working hard to keep you comfortable!
