Sometimes the smallest things that go unnoticed might be the most important tell-tale sign that something is not right. In the case of your A/C, it is the sounds it makes. It is one of the easiest ways to catch the problem early and prevent any further damage to your HVAC system. Professional help is just a ‘find an air conditioning installation near me’ search away! But first, you need to know what these sounds mean.

And with this article, we try to help you understand what your A/C is trying to convey with sounds so that you can make an early call and save yourself from paying extremely high electric bills! 

  • Banging

This sound can indicate a problem with the compressor of your A/C. The compressor distributes refrigerant throughout the HVAC system by removing the hot air from the room where the A/C is installed. The banging sound may indicate the loosening of compressor parts that end up colliding with the external metallic frame of the compressor. In case of any metallic sounds, there might be parts of your A/C that need replacement. Either way, this is not a fix-it-yourself job and might require professional AC repair in Alvin, TX for better assistance. 

  • Screeching 

The refrigerant that is circulated throughout the HVAC helps carry away the heat from the room, while a motor blower fan is provided within the indoor A/C unit to help distribute the cooled air in the room. The squealing or screeching is a sign that either this blower fan is malfunctioning or that the motor of the fan, installed as the outdoor unit, might be damaged. If the bearings of these fan motors are damaged, even then a screeching sound can be heard.

  • Buzzing or Humming 

Usually, these sounds are characteristic of an electrical issue that needs immediate attention. The problem can be due to a short-circuit in the contactor relay switch. Apart from this, the reason can be mechanical – dysfunctional fan blades, loose condenser coils, or even a problem with the copper lines. When you hear a buzz or a hum, it’s better to contact a professional, especially an electrician, so that the risk of the short growing into an electrical fire can be minimized.  

  • Bubbling 

This sound might translate to a problem with the pipes – either a block, a hole, or crack in the drainage pipe or severe damage to the pipe that carries the coolant or refrigerant leading to a refrigerant leak. This problem reduces the efficiency of the HVAC system and consumes a lot of energy which will get reflected in your monthly electricity bill.
