Air conditioners are not meant to be quiet—they’re machines that require grinding gears to work, along with various tubes and tunnels to keep your rooms cool and fresh. Normal noises are to be expected, but more often than not, these noises turn into things more serious. You may end up sitting one day, trying to make sense of the terrible noise you’ve just heard.
Any unexpected noise from an air conditioner could mean a symptom of a problem, which can range from a major to a minor one. In some cases, it could just mean that your air conditioner is getting older. Different noises pertain to different problems, and you’ll likely need the help of an expert to figure the issue out.
A home inspection can be made possible, however, up until the professional AC service team comes over. Here are some noises you need to be aware of—and take very seriously:
Noise #1: A buzzing sound
A buzzing noise from your air conditioner can be tricky to notice. No such sound will be present inside your home while it’s running, but walking past the machine outside will make the buzzing loud and clear. While buzzing bees may be welcome, anything of the sort from your unit could mean a problem in the condenser motor, circuit breaker, relay switch, and so on.
The buzzing sound indicates an electrical problem, one that needs to be addressed as quickly as possible. You may end up endangering your home and your family members, so contact a repair company as soon as possible.
Noise #2: Any hissing or whistling
A hissing sound can be a normal occurrence, so long that it lasts for only a few seconds. If it persists, however, you may be dealing with an expansion valve problem, now filled with a refrigerant gas leak. This usually occurs in the valves and lines and can be difficult to keep track of.
In some cases, however, the hissing and whistling sounds can eventually lead to high-pitched whistling, almost near whistling. This usually comes from the compressor, so it’s best to turn your air conditioning off—and refrain from using it until a technician comes.
Noise #3: Metal grinding
If your air conditioning unit begins exhibiting a metal grinding sound, you’re likely dealing with an unfortunate situation. If your unit begins making such a sound, you’ll do well to call a repair company as soon as possible.
The problem could be serious, such as a compressor problem and damaged belts. You’ll likely be compelled to change the compressor, or perhaps even replace the entire unit.
