Hearing a strange humming noise coming from your air conditioner can be unsettling. After all, your AC is supposed to provide relief from the heat, not create additional noise pollution. Has your air conditioner been humming more than usual lately? If you can’t find the noise source, it might be due to one of six possible causes. Some of them could be serious and could cause your unit to break down, so it’s important to have a professional take a look for possible AC repair.
If you’ve noticed a strange humming noise coming from your AC, it could be caused by electrical issues. The most common scenario is that your AC compressor is trying to start but can’t because the voltage is too low. This often happens when the unit isn’t getting enough power from the outlet or has a loose connection somewhere in the wiring. If the compressor tries to start too many times without enough power, it can overheat and cause permanent damage.
Another possibility is a problem with the capacitor, which supplies power to the compressor. A failing capacitor will also cause the compressor to try to start but fail, leading to overheating. If you suspect your AC’s humming noise is due to electrical issues, it’s best to call a certified technician for diagnosis and repair. Trying to fix the issue yourself could result in further damage or even injury.
An Issue with the Control Board
If your AC makes a strange humming sound, it could be due to an issue with the control board. The control board is responsible for turning the AC on and off and regulating the temperature. If the control board is failing, it can cause the AC to turn on and off erratically, which can create a humming sound. In some cases, the control board may also overheat, which can cause the AC to make a clicking sound.
You may also notice that your AC unit isn’t cooling as effectively as it should be. This is another sign of a problem with the control board, and you’ll need to call an AC repair technician in Keller, TX. If the control board isn’t the problem, they’ll be able to diagnose and repair the issue quickly.
Another possible cause of a strange humming sound coming from your AC is dirty coils. The evaporator and condenser coils are an important part of your AC system. The coils transfer heat from the air inside your home to the outside air if they are dirty. If they become caked with dust and dirt, they may not be able to function properly. For example, it can restrict airflow and cause the system to work harder than it needs to. As a result, the coils can overheat and begin to hum.
If you suspect your coils are dirty, you need to hire an air conditioning repair technician to clean them. This is not a job you should try to do yourself, as it’s important to avoid damaging the coils. While cleaning the coils can resolve the issue, you may need to replace them if the coils are severely damaged. This is mostly when they are neglected for too long and develop corrosion. Therefore, it is important to have your unit regularly serviced by an AC repair professional to ensure that the coils are clean and in good working condition.
A Refrigerant Leak
If you’re hearing a strange humming noise coming from your AC, it could be due to a refrigerant leak. A refrigerant is a substance used in air conditioning and refrigeration systems to transfer heat. When there is a leak, the refrigerant can escape and cause the system to malfunction. If you hear a humming sound coming from your AC, it is important to have it checked out by a professional as soon as possible to prevent further damage. This is because a refrigerant leak can also damage the compressor, leading to a costly air conditioning repair. A refrigerant leak can also harm your health if inhaled. If you believe you have a refrigerant leak, contact a qualified AC repair technician for help.
Thermostat Needs Calibration
If your AC makes a strange humming sound, it could be because the thermostat needs to be calibrated. The thermostat is an essential component of any AC unit and must be properly calibrated. If the thermostat is not calibrated, it can cause the AC unit to emit a strange humming sound.
In addition, a poorly calibrated thermostat can also lead to inefficient cooling, as the AC unit will not be able to regulate the temperature properly. As a result, it is important to have an AC repair technician calibrate the thermostat. They will be able to properly adjust the settings so that your AC unit can function properly and efficiently.
The Motor Is Overloaded
One final possible cause of a strange humming sound emanating from your air conditioner is overloading the motor. The motor is responsible for powering the air conditioner’s compressor; if it becomes overloaded, it can start to make a humming noise. There are a few different reasons why the motor might become overloaded, such as if the air conditioner is too big for the space it’s in or if the vents are blocked. Therefore, ensuring that your AC unit is the proper size for the space it is in and that all of the vents are clear is important. You can contact an AC repair technician in Keller, TX, for help if you’re still having trouble.
