Hello, my name is Darby Aldrich. I would like to talk to you about the importance of maintaining your air conditioning system. When I moved to a hot climate, I did not realize how vital having a running air conditioner was for living comfortably. When the unit just stopped working one day, the temperature inside the house rivaled the piping hot weather outdoors. We had to go to the community center to keep the kids from feeling sick. While we were gone, we had a local HVAC contractor fix the unit. She let us know that some simple maintenance tasks would prevent that situation in the future. I will use this site to closely explore those tasks in great detail. I hope you can use the information to keep your air conditioner running like new. Thanks.
Few people know what sounds should come from their ACs and which ones are cause for alarm. You should know that a new and functional system makes a low hum as it cools down the home. So, if the noise escalates to levels interrupting your daily activity, it is time to assess the unit for possible damage. Not that unusual sounds are a common sign of system complications. Here are the reasons why your AC might buzz and what you can do to fix the problem.
Assess the State of the Wiring
The most common reason AC units make buzzing noises is electrical faults, and changing the relay switch might solve the problem. Note that this is a low-voltage switch in your outdoor unit, operated by your indoor thermostat. Moreover, if it suddenly stops working, it will cause a tremendous buzz. Alternatively, the buzzing may result from something as simple as a loose electrical connection or as significant as the unit's age. No matter the cause, you should fix the issues immediately since they can cause electrical shorts and other catastrophes if you do not address them.
Check for Possible Frozen Components
The noise can also result from the air conditioner freezing up after being on for too long. If this occurs, you will need to unplug the device and wait for it to defrost. Ultimately, turning it back on after a few hours of rest shouldn't cause any problems. On the other hand, if your unit is experiencing frequent freezing or continued humming after a few hours of operation, it indicates a coolant leak. Note that this is a complex AC issue that needs servicing from an AC contractor.
Inspect the System for Loose and Moving Components
There are many moving parts inside your air conditioner, and it's not uncommon for some of them to vibrate when loose. Also, while it may not seem important, missing or loose parts can hinder the unit's efficiency and performance, leading to more costly issues. So, get an expert to disassemble and inspect for missing or damaged pieces. Once they make the necessary repairs, it should put an end to the noise.
Check If the Motor Powering the Fan Might Be Ruined
The condenser fan resides in the outer part of the AC unit. Note that the motor will be loud if your blower is running and the blades have stopped moving. In most cases, fan blades stop because of dirt inside the unit, they are broken, or there are loose components.
These are the common reasons why your system might be making these noises. So, speak to an AC repair technician if your unit has been making these noises to help you resolve them. Reach out to a professional for more information about air conditioning repair.
