Central air conditioners run quieter than ever before, which makes strange sounds more obvious. When you hear your AC starting to make noises you haven’t heard before, please don’t shrug them off. Often, these sounds are warnings to call our technicians for air conditioning repair in Conyers, GA.
Below is a list of some of the more common warning sounds you may hear from your AC and what they might mean.
This might be a simple issue: the door to the indoor cabinet isn’t fully latched. You can easily check to see if this is the case. Rattling can also mean screws or other parts that are coming loose, or the HVAC cabinet itself has come loose and is vibrating too much. This can lead to even greater damage later.
Grinding and shrieking
These are the sounds of motor problems. Shrieking is the noise a motor makes when its bearings are wearing down. This is a true warning sound because if you have professionals on the job soon enough, they can replace the bearings and keep the motor from burning out. Grinding usually means a motor is burning out and will need experts to replace it.
An electronic buzzing sound that you aren’t used to hearing is a warning of problems in the electrical components of the AC. The likely culprit is in the air conditioner’s control board, such as an electrical short or a damaged relay. Only AC technicians have the training necessary to fix these problems, and it can be dangerous to tamper with the control board on your own.
Clanging and banging
This is the noise of metal striking metal somewhere in the air conditioner. This can point toward many different loose parts, but one of the more common sources for these sounds is trouble in the blower assembly. A misaligned fan, a bent fan blade, or a loose part that has fallen into the assembly. The damage can be extensive if not stopped soon, so call for repairs right away.
Hissing or bubbling
These sounds are connected because they point toward a similar problem: leaking refrigerant. Refrigerant in gaseous form will make a hissing sound as it escapes through leaks in the refrigerant lines, and refrigerant in liquid form will make a bubbling sound. Loss of refrigerant puts the entire AC in jeopardy and will eventually lead to the compressor burning out. Please don’t hesitate to call for professional repairs if you suspect leaking refrigerant.
Loud noises in general
If you aren’t dealing with a specific odd noise from your air conditioner, just more noise than you usually expect from it, the problem may be larger than something a repair can take care of. An air conditioner that’s become a source of general noise pollution is often ready for a replacement. If your air conditioner is more than 10 years old, this amount of racket coming from it should prompt you to call us for a possible system replacement.
No matter the worry you have with your AC’s operation, you can trust our team to have the problem fixed fast and accurately.
