When your air conditioner is running smoothly, it tends to be relatively quiet, producing a gentle hum. However, unusual noises coming from your AC can be a clear indication that something is wrong. Ignoring these sounds can lead to more serious issues and costly repairs down the line. In this blog post, we’ll discuss five noises your AC shouldn’t make, what they might mean, and when to call us for AC repair in Dover, PA.
1. Banging or Clanking
If you hear a loud, metallic banging or clanking noise from your AC, it’s a sign that something is amiss. This sound often indicates that a part inside the unit is loose or broken. This noise might also be a sign that the fan blades are hitting something inside the unit.
Ignoring this sound can lead to more severe damage as the loose part continues to move around and potentially break other components. If you hear banging or clanking, it’s best to turn off your AC and call us to inspect and repair the unit.
2. Squealing or Screeching
A high-pitched squealing or screeching noise can be quite alarming. This noise typically points to a problem with the fan belt or blower motor. Over time, the fan belt can become worn out or misaligned, causing it to make a squealing sound.
Alternatively, the blower motor might need lubrication or could be malfunctioning. If left unchecked, these issues can lead to overheating or complete motor failure, which can be costly to repair.
3. Rattling or Chattering
A persistent rattling or chattering noise can be annoying and concerning. This sound often occurs when screws or bolts inside the unit become loose. It can also be caused by debris that has found its way into the AC or by a failing motor.
4. Hissing or Bubbling
A hissing or bubbling sound coming from your AC is usually a sign of a refrigerant leak. This noise can occur when there’s a high internal pressure issue or problems with the valves. Refrigerant leaks not only decrease your AC’s cooling efficiency but can also pose health hazards.
A sign of a refrigerant leak is an AC that is blowing lukewarm air, icy coils, and a home that doesn’t reach the desired temperature. If you suspect a refrigerant leak, it’s important to contact us immediately.
5. Buzzing
A continuous buzzing sound can indicate several issues, most commonly electrical problems. Loose wiring, failing electrical components, or a malfunctioning compressor can all cause buzzing noises.
Electrical issues are serious and can lead to complete system failure or even fire hazards. If you hear buzzing, turn off your AC and contact our HVAC professionals immediately.
Unusual noises from your air conditioner are more than just an annoyance; they are often a sign that something is wrong. Addressing these noises promptly can prevent further damage and costly repairs.
