Is your AC Making These 4 Sounds? It’s Time to Bring in the Experts

Uncategorized  |     |  

Ignoring unexplained noises from your air conditioner can transform little problems into significant expenses, as these noises could indicate anything from a simple tune-up to pricey repairs or, in the worst-case scenario, the complete replacement of the machine. The sooner you can figure out what’s causing the noise and fix your air conditioner problems, the better.

Here are some of the most frequent sounds your system might produce, as well as what they could mean.

  1. Clicking
    Electrical components clicking at start-up and shutdown is a regular element of system operation, but steady or continuous clicking is unusual. Constant clicking during operation may indicate an electrical problem, which can be extremely dangerous in a home. It could be an indication of a faulty control or a malfunctioning thermostat. As your unit has many electrical components, it is vital to address any potential electrical concerns as soon as possible before they become more serious.
  2. Buzzing
    A buzzing noise from your air conditioning system should never be ignored. This noise could indicate that your outdoor condenser unit’s fan blades are loose or imbalanced. Issues including a malfunctioning outdoor fan motor, filthy condenser coils, and loose components can all produce this type of noise. A buzzing sound could potentially be an indication of a blockage near your air conditioner’s copper lines. A refrigerant leak is the most serious issue that could be causing this situation. Please don’t dismiss a buzzing noise. Hire a professional expert to execute an air conditioner tune-up to be proactive and prepared for the summer season.
  3. High-Pitched Whistling
    Shut off the air conditioner and call a specialist at once if you hear high-pitched whistling or screaming. A refrigerant leak is the most likely reason, which can harm not only your air conditioner but also your family’s health. High-pitched could potentially signal a dangerously high internal pressure within your compressor. Don’t be alarmed if your air conditioner shuts down on its own. Take this as a positive. A sensor is performing its job to keep you safe in an otherwise dangerous scenario.
  4. Whirring Noise
    If your air conditioner sounds suspiciously like a helicopter, it could be due to various mechanical issues with the indoor blower or the exterior unit. Poor bearings in the interior blower fan motor or a malfunctioning fan in the indoor or outside blower unit are the most common causes of a whirling sound in an air conditioner. A whirring, helicopter-like noise might occur when the blades start to come loose, or the fan otherwise starts to fall apart.
