Like all machinery with moving parts, every air conditioner will make some noise when operating. However, certain noises can be clear signs that your HVAC system needs to be inspected by a qualified professional.
In these cases, when your HVAC system is humming, buzzing, banging, or making noises that don’t sound right, no one in Manteca is more qualified than the hard-working professionals here at Star Mechanical. 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 system issue — different types of noise can indicate various problems. To help our customers 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 many 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 equipment can make. Because of this, it can be relatively easy to identify the cause. That’s when a professional eye is the most valuable!
Humming
While humming and buzzing might sound similar, distinct differences can generally be recognized once they’re heard. Humming is typically a sign of electrical issues and requires the eyes and ears of someone trained to pinpoint it. You never want to risk electrical damage or even a fire, so pay attention to the humming from your AC unit.
Banging/Knocking Sounds
Suppose you turn on your HVAC system and hear a sound like metal banging against metal. In that case, 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 be caused by a faulty motor blade or any other improperly functioning or obstructed fast-moving part.
Squeaks ‘N Squeals
A few problematic areas of an HVAC system could cause it to squeak or squeal. Generally, these noises are caused by issues with your fan motor, compressor, or any of the belts your unit uses.
Loud Screaming
Loud, alarming noises are a sure sign that you should immediately shut off your HVAC system. These noisy, obstructive sounds are typically caused by leaks in the pressurized refrigerant system or faults in the high-pressure compressor.
