At Brown Heating, Cooling & Plumbing, we’re here to help answer your questions about air conditioner noises and help you find a solution. Scheduling maintenance for your AC may seem daunting, but with our guidance, you’ll be well on your way to a quieter home.
Are AC Noises Bad?
Your cooling system is bound to make a few occasional noises. Infrequent sounds aren’t an indicator of a problem with your unit. If you notice your air conditioner making a frequent commotion, a problem is likely present. A few sounds to look out for are:
- Rattling
- Banging
- Clanking
- Clicking
- Squealing
When your system sounds like the inside of a robot, don’t ignore it! These noises indicate that the machinery isn’t operating as it should. Additionally, they may be a warning sign of a potential breakdown if overlooked.
What Causes Loud AC Noises?
The world of AC noises is huge. As a homeowner, you may experience many different types of sounds, each of which may be caused by operational issues. You’ll need to address the problem causing the noise rather than tuning it out.
Loose Parts
Loose parts inside the machine cause many types of noises. Old AC units break down over time, which can cause the smaller internal parts to come loose. Since there are moving parts in the system, like the fan and motors, these loose components might get spun around inside the unit.
If you notice a rattling sound in your air conditioner, a loose part is probably the culprit. Loose parts can also cause banging and humming if caught between two moving components. The best way to address this issue is to contact your local Hueytown AC professionals at Brown Heating, Cooling & Plumbing. A technician will locate and replace the broken parts without causing further damage.
Dirt And Debris
When dirt and debris get stuck in your unit, you may hear buzzing or humming. If you notice a buzzing coming from your outdoor unit, a stick or leaf might be caught in the outdoor unit. If you hear buzzing inside your home, it could be from a dirty air filter or filthy ductwork.
Broken Blower Or Fan
When the motors that control the fan and blower in your air conditioner start to fail and break, they might produce a loud squeaking or squealing noise. Some AC units, especially older ones, make this squealing noise when first turned on. However, constant squealing is not normal and should be addressed by an HVAC professional.
Refrigerant Leak
The most dangerous AC noise is caused by a refrigerant leak. Usually, this problem produces a whistling sound, indicating the pressure is high inside your unit. Breathing in refrigerant can be dangerous for your health, so it’s important to turn off your system as soon as any whistling or screeching starts.
Many units will automatically shut off when they detect a refrigerant leak. However, it’s best to act fast and turn off the machinery as soon as you hear any obnoxious sounds to prevent potential health effects. Once you turn off the unit, schedule maintenance as soon as possible.
