We’ve seen countless homeowners struggle with one common issue: noisy air conditioning units. Your air conditioner should keep your home comfortable without drawing attention to itself. But when it starts making unusual noises, it’s a sign that something could be wrong. Ignoring those sounds might lead to bigger, more expensive problems down the road.
Today, we’ll examine the common reasons behind a noisy AC and how our Peaden Pros can help you restore peace and quiet to your home with AC repair.
Common Noises Your AC Might Make
Let’s start first by looking at the most common noises that a faulty AC may make.
- Banging: A loud banging sound typically signals a major issue with the compressor or another internal component. This could mean that a part has come loose and is knocking around inside the unit, or the compressor itself is worn out. In either case, you’ll want to address this issue quickly before more serious damage occurs.
- Clicking: It’s normal to hear a clicking sound when your AC unit turns on or off. But if the clicking becomes continuous, it could indicate a problem with the electrical system such as a faulty relay or a loose connection. Electrical issues should be addressed immediately to avoid the risk of more serious system failures.
- Buzzing: A buzzing noise can stem from several causes. It may be a sign of loose parts, debris inside the outdoor unit, or an issue with the condenser coil or fan motor. In some cases, buzzing could also point to an electrical problem, like a malfunctioning contactor.
- Squealing or Screeching: High-pitched squealing or screeching usually points to a problem with the fan motor or blower. Worn-out belts or bearings can cause these noises, especially in older AC units. Left unchecked, these components may eventually fail, leading to a complete system breakdown.
- Hissing: A hissing sound could signal a refrigerant leak, which can severely impact the efficiency of your AC system. Low refrigerant levels not only make cooling less effective but also strain the compressor, potentially leading to an expensive repair or replacement. If you hear hissing, it’s time to call in a professional for a thorough inspection.
- Rattling: Rattling sounds may indicate loose components, such as screws or bolts, inside your unit. Over time, vibration from the AC can loosen parts, leading to this noise. It’s often a simple fix, but if left unaddressed, loose parts can cause more significant damage to your system.
