All machinery usually make some kind of low noise when they are working, such as the hum of your refrigerator or the sound of your oven heating. Your air conditioning unit makes noises too when it’s on, as its fan spins and the cooled air is pushed into your home. However, most of us can recognize the sound of a piece of machinery that really shouldn’t be making that particular noise, such as a grinding sound or an irritating sound. When you hear this sound, you know it’s time to call in a professional technician to investigate.

WHAT THE SOUNDS OF YOUR AIR CONDITIONING UNIT MEAN

You hear a buzzing sound

If your air conditioner is buzzing, give Boyd Brothers Services a call. Your AC unit (like all machinery) is composed of many parts. This weird buzzing sound usually is either one of those parts that has come loose, missing or broken isolation feet, refrigerant leaks, or a compressor that is not happy.

  • A loose part can put pressure on the other components of your AC unit that can lead to wear and tear until that leads to the buzzing noise you are hearing.
  • Isolation feet are basically the stands that elevate your AC unit a few inches off the ground. Like all mechanical parts, these feet can break, crack, or otherwise wear out, causing your air conditioner to tip. This slight tip is just enough to move the parts out of alignment and create a buzzing sound.
  • Refrigerant lives in the coils of your air conditioner and is the substance that cools the air intake. First, refrigerant absorbs heat from the interior of your home. It passes over the fan, which blows the hot air out. Then the refrigerant cools back down, returning to your home and bringing cool air with it that is then transferred to the interior of your home by a separate fan located inside your home. This process is how your air conditioner works. However, if anything goes awry in this process, the refrigerant can leak, causing a buzzing sound.
  • There may be a problem with your compressor. The compressor in your AC unit works with the refrigerant to cool down your home. The compressors’ job in your AC unit is to keep the refrigerant flowing. It does this by raising and lowering the temperature and the pressure of the refrigerant in accordance with where it’s at in the process.
  • Debris may have fallen into your outdoor or indoor unit.
  • Outdoor fan motor or the blower may be failing.
  • Some part of the AC unit needs to be cleaned or changed, such as your air filter or condenser.

You hear a banging noise.

Compressor problems usually have a loud banging sound, indicating a connecting rod, piston pin, or crankshaft is loose inside the air conditioning compressor.

You hear a clanking noise

As we’ve discussed, your air conditioning unit has fan blades. Either your indoor blower or outdoor fan gets out of balance, resulting in your fan blades hitting other parts of your air conditioning unit. This is not a good thing. Furthermore, the air conditioning compressor itself can become loose, making a horrible clanking noise, or other component parts may be rubbing or hitting other parts. Call Boyd Brothers Services, your expert AC company in Punta Gorda, today for an inspection.

You hear an abnormal amount of clicking noises

All AC units make a clicking noise to indicate when it turns on and when it turns off. However, if you are hearing too many of these on and off indicators or you are hearing clicking noises when you shouldn’t be, odds are you are dealing with a defective control or a thermostat that is failing. These electrical components should be investigated right away to prevent any electrical issues in other parts of your home.

High-pitched squealing

Worse than a two-year old throwing a temper tantrum, high-pitched squealing usually indicates a blower or a motor is going out. These squeals can be transmitted through your AC ductwork, which is sure to get your attention.

Humming

Humming usually indicates vibrations, which can be the first sign of something major about to break. This AC maintenance problem can range from electrical, loose parts, wiring, or even piping.

Rattling

Rattling usually indicates something is moving around in your air conditioner unit that shouldn’t be. Twigs or leaves could be the cause. The fan itself rattles when loose, as does the loose screws or bolts. Rattling, when taken care of by a professional air conditioning repair company like Boyd Brothers Services in Punta Gorda, is usually just an indication of light maintenance tasks that need to be completed.

Screaming

Anytime you hear screaming if life, it’s usually an emergency, and you naturally come running. This is the same thing you should do if your air conditioner starts screaming — you should stop whatever you are doing, and shut down the air conditioner immediately. This whistling or screaming sound usually indicates refrigerant is leaking, or it’s a sign your compressor is about to blow. If your AC is blowing refrigerant into your home, you can get refrigerant poisoning, which is when you inhale an unhealthy dose of freon (the gas in refrigerant) that can be deadly in extreme cases. Hopefully, an internal sensor shut off the air conditioning for you. Either way, you’ll need to have your local HVAC company (Boyd Brothers Services in Punta Gorda) take a look at your AC unit before you can use it again.
