Like all machinery with moving parts, every air conditioner is going to make some noise when in operation. However, certain noises can be clear signs that your HVAC system needs to be inspected by a qualified professional.

When you’re dealing with a noisy air conditioner and require Manteca AC repair, we’re here and qualified to provide any HVAC services, 24/7.
Fortunately, an AC making noise can also be an important clue in diagnosing the issue with the system — different types of noises can be indicative of different problems. To help our customers out and give you an idea of what the noises coming from your AC could mean, here is a breakdown of the most common noises and their potential causes.
Buzzing Noises
Buzzing can be one of the more common, and unfortunately difficult to diagnose, problematic noises your system can make. This is because there are a lot of issues, large and small, that could cause your unit to buzz. Some of the many reasons your AC might be buzzing are:
- Debris in the outdoor unit
- Dirty air filters
- Potential freezing
- Malfunctioning blower motor or compressor
- Random loose parts
Buzzing is one of the most ambiguous sounds any piece of equipment can make, and because of this, it can be notoriously difficult to identify the cause of it. That’s when a professional eye is the most valuable!
Humming
While humming and buzzing might sound similar, there are distinct differences that can generally be recognized once they’re heard. Humming is generally a sign of electrical issues and requires the eyes and ears of someone trained to truly pinpoint. You never want to risk electrical damage or even a fire, so make sure you pay attention to the humming from your AC unit.
Banging/Knocking Sounds
If you turn your HVAC system on and hear something that sounds like metal banging against metal, it’s probably a sign that something is wrong with your compressor and the rod/crankshaft used to reheat refrigerant in the system.
Sometimes, banging or clanking can also be caused by a faulty motor blade or any other improperly functioning or obstructed fast-moving part.
Squeaks ‘N Squeals
There are a few problematic areas of an HVAC system that could cause it to squeak or squeal. Generally, these noises are either caused by issues with your fan motor, compressor or any number of belts that your unit may use.
Loud Screaming
Loud and alarming noises are a sure sign that you want to immediately shut off your HVAC system. These loud, obstructive noises tend to be caused by breaches in the pressurized refrigerant system or faults in the high-pressure compressor.
