Let’s continue answering the question: “Why is my AC so loud?” Here in Texas, it is not a form of competition who has the loudest AC in the summer. With temperatures being so high, in Plano, Carrollton, and other cities we cover, it is not fun when your AC starts sounding funny.
Here are some noises you can hear:
Let’s take a look at those strange noises.
Reasons: loose parts, old parts
Most units have some minor type of pulse emanating from them, which is entirely normal. However, this pulsing should be barely audible unless you are really listening for it. If an outdoor unit begins to make noises that you can hear inside, some parts are likely loose and some part inside the unit needs to be repaired or replaced.
Reasons: outdoor debris, electrical contractor, loosening parts
Sometimes outdoor debris like leaves and branches can get caught in your system, causing a clogging issue. Also, it can indicate loose things, flying around. Your first troubleshooting actions should include checking to make sure that all of the bolts and screws in the unit are tight and snug.
Reasons: degradation, damaged housing, blower wheels
Squealing can be indicative of malfunctioning or damaged housing or blower wheels. Some units may have natural squealing, so to speak, so keep your ears open for sounds when it does not sound like, as they say, normal squealing.
Reasons: refrigerant leak, over-pressurization
The one noise that calls for an immediate ceasing of the use of your AC unit is if you begin to hear a “screaming” or high-pitched whistling noise. At this point, drop everything and call Dragon Air Services. In some situations with this type of problem, the AC unit is equipped with a sensor that will shut the unit off. If this happens, don’t worry. This is a failsafe mechanism included for your safety.
Reasons: bad bearings, bad fan, torn or ripped belt, displaced or loosened fan blades
If your AC sounds as if a helicopter flies overhead, that’s when you really want to ask: “Why is my AC so loud?” and the outdoor unit or the indoor blower may be having a difficult time operating properly in Texas heat. Usually, a whirring sound is indicative of bad bearings around the indoor blower, or a bad fan on either the external or internal AC. The helicopter-like noise occurs when the blades are spinning at an angle, out of place, or hitting what they should not be.
If your air conditioner needs replacement, look into a company that can provide a strong warranty. This could save you substantial money on costs or the unit and its installation. This will also help you rest assured that you are operating a newer, quieter, and more reliable AC unit.
